I've challenged myself to get 50 items listed on my Etsy store by November 16 when I will have a 50% off sale on my 50th birthday.
Let's do this!

WatUR: The World's Oldest Board Game, Modurnized
I've been working on a new project all summer. I saw a video in April of Tom Scott and Irving Finkel playing an ancient board game and I became obsessed with it. I loved the dice especially. It uses four dice that represent 0 or 1. You add them up. This appeals to me because I have trouble adding big numbers and I have some relatives with the same genetic deficiency. It's not an impediment to doing higher mathematics or anything, but if you're playing a game for fun it's nice to be able to relax and not have to face your shortcomings whenever the dice come up with too many spots showing.
I decided I could make this game myself. It's 4500 years old, surely it's in the public domain. I got some blank tetrahedral dice like they found in the Royal Tomb in Ur and I modified them for the game. The ones in the museum were carved from bone. I was ready to embrace modern materials though, so I used plastic.
I had some scrap 1x6 pine boards so I cut out the shape of the board. I bought Affinity Designer when they came out with the upgrade recently so I set out to learn that software and design the decorations for the squares. I studied the original closely.
I don't actually like the original design. It's a lot of variations of the all-seeing eye and it sort of creeps me out. There are a lot of copies of this game and they all just look like this. Why? As long as the designs repeat in the same places it could be anything. Why not be original when you're copying the oldest board game in the world?
I thought the 5 spot squares looked like frog eggs. So I designed Frog Ur as my first version.
I tried several of these but I felt compelled to be true to the 8 pointed rosette theme that ran through all the artifacts I saw on the British Museum website. I finally came across Enki, the god of Water. He was often shown as a mountain goat with a fish body, or he had a river just shooting out of his head with fish jumping in it. That's how I settled on WatUR, with mountain goats, turtles, fish, and sun and stars instead of rosettes.
I made some more of the wood boards with decals and played it with a friend. He complained that the dice were hard to pick up. I didn't mind sliding them off the table, but I wasn't crazy about how hard it is to make them. I'd contacted all the dice makers to see if they could customize these dice to have contrast colored tips and they refused to even try. They were happy to customize dice on the flat faces. So I decided I could solve two problems at once by having 6 sided dice made to only have 2 outcomes. Put spots on 3 sides, leave 3 sides blank. Now the odds are the same as the tetrahedral dice. And it's this probability that makes the game work. The fact that your opponent is more likely to roll a 2 than a 1 or a 3 helps you decide where to put your pieces.
I found some ready-made binary dice that had 1 and 0 on them. 1 and 0 made me think of digital logic and that made me think of printed circuit boards. TransistUR was born.
I did some research and found there are prototype board houses in China with no set-up charges and quite a low fee per board. Cost less for fiberglass cut with a CNC router and shipped express from China than it costs me to cut out a piece of wood and sand it, let alone decorate it and hand paint it.
While I was working on my board layout I was also exploring the possibility of doing laser engraving on wood. In the process of getting the vector file to a laser engraver I figured out I could convert my Affinity Designer files to AutoCAD format, good old DXF. And the board layout program can import that. In just a day or so I had my WatUR design rendered as a printed circuit board too. But I can't have 1 and 0 with Sumerian artifacts. They used cuneiform, not Arabic numbers. So I had to find a source for custom dice. It turns out they're just as affordable as the circuit boards. But only if you buy 2000 of them.
But by now I really really wanted them. I kept working on the rest of the steps to product launch and decided I could do it if I could get 250 people to pay $35 ea for a set.
I'll come back and paste in a link to the KickstarUR when after I launch it some time this week.

Hurricane Harvey is no Wilma. Now we have iPhones.
— Holly 🚀 (@absolutspacegrl) August 27, 2017I saw a lot of people on Twitter talking about praying. This is not an interesting activity for me. Where are all the people wondering why there were cars completely submerged with their headlights on? There were interstate height lamp posts with water within a few feet of the canopy and they were still on, shining on the water. I have so many questions! How much electrical current is running through that water? What's the conductivity? Is everything getting electroplated? Or the reverse, corroded? Is there a system to disconnect power to electrical infrastructure when they go underwater? I'm thinking of telephone nodes, street light controllers, stuff like that. Why are people playing in this water today? Do they have no understanding of risk?! Electricity aside, think of the live fire ants floating around in rafts. People trying to help their neighbors, that's one thing. But just playing, that's not cool.

I can't stop thinking ahead to what the recovery from this will be like. I'm remembering back to 2005, 4 years before I started this blog, when Hurricane Wilma went for a wild ride all around the Gulf of Mexico. It forced my step-sister to move her wedding from Isla Mujeres, Mexico to Destin, Florida, in the panhandle, on five days notice. My brother and his daughters, who had flower girl dresses made, couldn't come from South Florida because of gasoline shortages.
I was working for a civil engineering firm in Tallahassee at the time. They had a disaster recovery division that got a contract with Broward County (Fort Lauderdale area) to manage the clean up effort. I was sent down there to work on it. I took my personal laptop, cell phone, GPS, camera, and car. They gave me a company hard hat and a company safety vest. I went to Walmart and bought some steel toed boots.
My job was to go out to neighborhoods with private contractors who had come from all over the country with loaders and dump trucks. All I had to do was stand there and watch them load trucks with debris. When the truck was full I filled out a form with many duplicates. It had the time and date and how full I thought the truck was. Then I gave the driver one copy and he went to dump the load at the landfill where they were grinding up all this organic debris.
The landfill where the trucks took debris to be ground into bits small enough to move efficiently |
Ficus trees down everywhere |
The kind of neighborhood that got cleaned up first in Broward County |
Most people don't even have power back on, but by all means, run the pump on your fountain |
Even the peacock thinks he owns the public property |
On MLK drive we couldn't pick up empty cans, but we were told to collect anything these people put out by the road. What is that, a trampoline? |
3.25 Acres, Pool, 6 Horse Stall Barn |
When they'd block the road like this they'd have to stop working to let cars go by. Over and over. |
I was quite content to watch this machine all day. This guy got that thing on three wheels all the time. |
For my next assignment I was sent to document tree damage in the right of way of a small municipality. I started out with a partner who was a temp hire who came from up North somewhere excited by the high pay. On the first stop she told me I was using my GPS wrong. "You have to point it at the tree." I tried to explain that SHE was using it wrong, for maximum precision we should go all the way up to the tree and point it at the sky. But the error was so big it was fine to take the reading from where we took the photo and get it done as quickly as possible. Accurate final count more important than precision. The next day she told me she'd called her pastor from the hotel and he'd advised her to talk to me to be sure I'd accepted Jesus Christ as my savior. By lunchtime I'd gotten the city manager to let me do the whole job alone. I designed a database in my hotel overnight to use instead of the paper form and I personally documented all the trees down in the right of way for an entire Broward County town, uploading the GPS waypoints and photos into the database directly. They were so amazed by my grasp of technology.
That was in 2005. Remember 2005? This was 2 years before the invention of the iPhone. There were some modules you could use with DSLRs to put the GPS coordinates in the metadata of digital photos but they were out of my reach. But now everybody has a device in their pocket that can document storm damage with the GPS location embedded in the metadata of every photo. This job now would not require a salaried scientist to drive every mile of road in a town or county. You would just need to scrape the data off social media. Instead of writing a receipt for every truck of debris you just have the driver snap a photo and text it to a specific number where it could automatically be recorded in a database.
The key to efficient management is a robust cellular data network and a few good computer scientists. We still need people with chain saws, dump trucks, and loaders, but a lot of the expense for people like me to stand there and just watch them all day is sort of obsolete.
I'm curious if these systems are already in place. If they aren't then I am going to be extra bitter than I was wasting my time in 2005 trying to point people in the right direction with innovation. But when am I not extra bitter? Nothing really changes.

I can't think of a better name for a 4x4
Yesterday I saw a story on FHB about a Chicago law firm filing suit against Menards and Home Depot for selling 4x4s that are only 3 1/2" x 3 1/2". They included some tweets from people reacting to this news. I'm sort of glad I saw this hot take first because it pointed out to me how unnecessary it is to be mean about people who don't know that the name refers to the nominal rough cut size and that the dried planed 4x4 is a standard dimension of 3 1/2" square.
I see nothing wrong with not knowing that. The people that don't know standard lumber dimensions are not stupid. They probably know a ton of stuff I don't know, like how to keep score in tennis or what it's like to shovel snow.
To me this seems more of an opportunity to educate than a need to mock people who never had to build a deck before. I find the process of turning trees into studs and posts fascinating. It seems like an opportunity for watching a YouTube videos that shows how there are a lot of steps after sawing a board into a 4"x4" post before it turns up at Home Depot, mainly it gets dried, which shrinks it, and then it gets planed on all 4 sides, which gets it down to the final standard dimension.
I started an informal Twitter poll to see how many people think a 4x4 is really 4x4. More than I would've thought. 75% of respondents knew 4x4 was nominal and not the actual size. 25% really thought it was 4 inches square. (n=44, which is a lot more than the 18 questioned in the store for the original story, and they got 1/3 not knowing vs my 1/4)
I found anecdotal evidence that Norwegians have their own lumber dimensions, 95 mm for a 4x4, which is about 3 3/4", 1/4" bigger than the American version. They dimension drawings and give the specs in mm. This used to be true for the US as well. When I did AutoCAD work for the Army Corps of Engineers in the '90s they required all architectural plans to be dimensioned in mm. According to David Luke at Merrick this is no longer the case. They dropped that requirement around 2005.
But even though the actual size may vary my research shows that all around they world they still say "two by four" to refer to a standard piece of framing lumber. (Here's an interesting pdf about Japan where they have their own standard stick frame construction but "2x4" is still part of the name. It's based on a 3'x6' panel convention vs our 4'x8' version. This sounds good to me. I might not have such an aversion to doing anything with sheet goods if they were that small. Apparently 3'x6' is the standard size of a traditional tatami mat.)
I haven't come up with any good ideas for better names for 4x4s, 2x4s, etc. It doesn't really make sense to rename them based on a round metric number since everything else is still in inches and feet. I would support a sudden change to metric though. I could learn to say 90x90 and 40x90 as easily as I converted myself from °F to °C. (I just flipped the switch on my thermostats and weather app and learned that 25°C is a good nominal summer air conditioner setting. I think of 15°C as a summer night in the UK and anything less than that I call cold.)
Anyway, back to the lawsuit. Home Depot clearly states the actual size of all their lumber on their website. And if you're in the store you can see what size it is with your actual eyeballs and get a tape measure out of your purse and measure it if you want to.
Here's the description of a Pressure Treated 4x4x8 (which they seem to have measured soaking wet). I don't think anything will come from this except that a lot of people may learn what nominal and actual mean.
Interestingly you can also learn lots of other information about lumber from the Home Depot website by reading the reviews. Yes, a 4x4 is going to twist like a bitch when it dries. Prepare yourself. I learned to install my deck railing posts long and brace them diagonally until they dried in place. Then I took off the braces and cut them to length and finished the railing.
Good luck to all the DIYers out there. It's hard enough with the names of the wood not matching the measurement without people in the trades mocking you for not knowing it. But getting mad in the Home Depot reviews because wood acts like wood is pretty mean too. Acting all butthurt when carpentry turns out to be a lot harder than it looks on HGTV is insulting to people who do this for a living so I sort of get why they turn so mean.

I also got some comments from people saying it's not the same where they are, outside the US. I did some digging to see what people call dimensional lumber in other countries, particularly ones that use the metric system. They still call a stud a 2x4 or maybe a 4x2. Wikipedia says that they say timber instead of lumber for building materials, but I haven't been able to confirm this.You buy a standard 8' long square post that is called a 4x4.

An Ultimate Guide or Fair Warning
This morning I read an article about introverts that basically describes the arc of my life but it's written by a white dude and somehow his superiority over figuring it out kinda irks me. This is not advice anybody else needs, dude. To assume everybody else is deficient because they still regularly do things they don't like is obnoxious. I'm kind of jealous of them that they don't seem to mind other people telling them what to do. I wish I had that ability.
I think what really got under my skin was his unrecognized privilege. Just delegate anything you don't want to do; profit! If my blog comes across like that then I'm mortified. I try to write stuff less as advice and more as a reminder to myself of how freaking hard it was. I hope I don't sound like I'm advising other people to be like me. I guess since I often put more than one sentence in a paragraph I'm probably not at risk of being another James Altucher, even though I am the exact same age and have similar introvert coping strategies.
Also he forgot to mention the importance of arranging your life so you can live without a lot of money. None of this works if you have a mortgage and two kids to put through college. I guess if you're a white man it works out for you because people will still give you a lot of money for trivial effort instead of expecting you to do complex tasks or pennies per hour.
I don't think I'm very good at anything. I'm a generalist. Sometimes I find myself thinking, "That was easier than I thought it was gonna be." But I NEVER say "That was harder than I thought it would be." I am happy to go into a new task with open ended expectations. It takes as long as it takes. I try to plan stopping places to accommodate my physical limitations. But it would be an insult to people with experience and skills to presume anything I don't know how to do is going to be easy.
An ex-boyfriend of mine called me recently and asked how to build and insulate walls and a ceiling inside an airplane hangar. I told him. I sent him YouTube links to Fine Homebuilding videos to watch to learn techniques. He called me a few weeks later and said it was a lot harder than he expected. So many layers! Yeah, I know. He lived with me while I was building an addition on a house in Atlanta and we still dated for a year after I had to move away and build a whole other house from scratch where I could live on less money. But I guess mainly he wasn't paying attention. Not sure why he assumed it was easy. I was a little insulted. It was only slightly gratifying that now he understands that carpentry is damn hard. His room doesn't even have to be weatherproof or survive live loads and he thought it was hard. You think that's complicated layers, do it again to stand up to wind and keep out rain. Good grief.
I made a video last week that is over 17 minutes of showing exactly how hard it is to ombré dye a heavy cotton sweater. When I finished the project I didn't really know how to show the end product. I decided to try the Facetime camera on my monitor to record straight into iMovie. It's great to have an articulating arm on my monitor. I did the rest handheld with my phone. I would normally never do anything with such low production value, but the bar is so low now for how-to videos on YouTube it would seem like topping it the knob to use a tripod and a real camera. I was surprised how good that dot on my monitor works as a camera. Free with $1000 monitor. Why didn't I try it before? Probably because I was horrified at the idea of actually appearing on camera. I think I have passed a Fuck It threshold. It must be this Nazi Youth haircut I got by accident at the walk-in barbershop a few weeks ago. (FYI, fashy is short for fascist, not fashionable.) I had the Facetime camera intentionally chop off the top of my head so the place where they shaved off my cowlick isn't so obvious. Thanks to being an always-alone introvert it's not a big deal if my hair looks stupid. I only go out in the daytime and it's perfectly acceptable that I always have on a hat. I started to do the video in a wig AND hat but I thought it would be draw the eye away from the flaws I was pointing out in the sweater.
I really never meant anybody to see this video but me and my niece Kara who is into crafty stuff. She said it was a good video. She wants me to dye a hat next. But I might as well put it on here since it's thematically valid. This is not a how-to, it's for me, and for people who were thinking about trying to dye a sweater and need to be talked out of it. Maybe that's the Ultimate Guide we all need. You have a fun creative idea and you look for tips on YouTube and wind up saying fuck, that's a lot of work and what would I even do with that? Never mind. (I'm looking at you, making a hollow concrete sphere with fiberglass and a yoga ball.)

I guess since I often put more than one sentence in a paragraph I'm probably not at risk of being another James Altucher, even though I am the exact same age and have similar introvert coping strategies.
From The Ultimate Guide to Being an Introvert by James Altucher: (highlights)Notations by me
How I Deal With Being an Introvert
#1 — FIRST “Quiet” by Susan Cain is a good book.This is a book, not a coping strategy.
#2 — CREATE A LIFE WHERE YOU CAN HAVE MORE TIME BY YOURSELFDone. Most days I wake up and can't wait to go to my lab to do whatever I feel like doing that day, all by myself.
#3 — ONE PERCENT RULE
Every day I want to make more choices for myself, instead of letting other people make choices for me.I'm up to 99.9% on #3. I take commissions but they mostly tell me what to make, not how to make it. This is the most important part to me.
#4–15 YEARS, GIVE OR TAKE TEN
It took me a long time to realize I wasn’t shy. I thought the reason I had trouble talking to people in groups was because I was shy or insecure.Nah, I just thought it was because they didn't like me.
That’s the ten years part. I was so deluded about my strengths that it took me ten years. Maybe it will take you fewer.Or maybe I'm not deluded, I just lack the white male privilege to get away with treating people like they don't matter to me.
#5 — NO MONEY REQUIRED
It requires asking yourself throughout the day: is this activity giving me energy or draining me?
Energy is everything in life. At night we have little of it, so we need to sleep.
When an introvert is around a lot of people, it drains quickly.
When you are around people who put you down, it drains instantly.
When you aren’t creative, it drains.
When you aren’t happy with your current moment, it drains because anxiety and regret are leeches on our energy.
When you are with someone you don’t love, it drains.
When you are at a job you don’t like, it disappears.
Note that none of the above has anything to do with money.
Energy is more important than money. Energy is what makes you live a long and productive and happy life.
If I wanted a billion dollars I wouldn’t sit around writing and reading and podcasting a good chunk of the day.
I wouldn’t hire people to help me run the various businesses I’m involved in because it’s hard for me to meet with employees and do “business things”.
I’d run a hedge fund, or directly run my businesses, or buy a company and become a CEO. I’ve done these things before and failed miserably.
Not because I don’t have the knowledge. But because it doesn’t make me happy. And those activities drain me.If I could hire people to run various businesses I'd be a white man and not a woman who has to do everything her damn self. If I was a white man people wouldn't ask me to do shit that hurts my hands and back because I have seemingly endless free time and lady skills like dusting, vacuuming, laundry, dishes, and a unique skill at restoring plumbing fixtures. If I was a white man could I get four figures for couture knitted items and sci-art instead of getting orders from relatives who want to pay the same thing they would pay for clothes at Target?
Also he forgot to mention the importance of arranging your life so you can live without a lot of money. None of this works if you have a mortgage and two kids to put through college. I guess if you're a white man it works out for you because people will still give you a lot of money for trivial effort instead of expecting you to do complex tasks or pennies per hour.
#6: HUMILITY IS MORE IMPORTANT THAN SELF-ESTEEM
Be humble enough to realize what you are not good at.I have never been afraid to try something I've never done before. It was sort of my professional speciality back in the day. I'd come along as a consultant and figure out the new thing and then when it didn't turn out to be as profitable as the management thought (because they assumed it would be easy) I'd leave and they'd blame the whole thing on me. Everybody goes on with their life.
I don't think I'm very good at anything. I'm a generalist. Sometimes I find myself thinking, "That was easier than I thought it was gonna be." But I NEVER say "That was harder than I thought it would be." I am happy to go into a new task with open ended expectations. It takes as long as it takes.

How I made a minisplit line chase out of vinyl gutter
When I decided to recaulk and repaint my lap siding I thought it was finally time to do something about this eyesore on the north side of my house.
Refrigerant lines, condensation drip, and control power for my minisplit air conditioner inside wall unit |
This is the penetration through the wall |
The rest of the situation is pretty abominable though. I screwed something to the wall like a giant hook for storing ladders for the technician to secure the lines to when he installed them. Then when I put up the siding I replaced it with a small Simpson Strong Tie bracket and wired the lines to it. The algae growing on the insulation is pretty embarrassing.
Clearly that pipe insulation needs to be replaced. And as long as I'm painting I should remove the insulation and paint underneath with less junk in my way. And then I should put the whole business inside some kind of enclosure.
This L bracket fiasco is my own doing |
I tried to figure out a way to do it with round aluminum duct. I was thinking of that kind that has a crimped seam on the long edge that you push together to make a cylinder. It would look cool, but I couldn't figure out how to do the L bend at the top.
So I went to work figuring out how to do it with vinyl K-gutter. This stuff is stupid cheap. 10' sections are less than $4. I bought one piece and brought it home to play with it. I was thinking I could just put it over the lines with the flat side against the house. But it wasn't deep enough. So I decided to figure out how to make a clamshell out of it. I got a preformed inside corner and an outside corner and some joiners and started figuring out how to cut it.
Cutting PVC gutter
To make the clamshell work I had to cut the folded over parts off the bottom half of the shell. This is a two step process and takes two different tools.
To cut off the lip on the flat side I used a 4x4 clamped to a table as a rest for a jigsaw. I pushed the saw through the vinyl, then slid the whole business back, repeating until the whole length was cut.
Use a jigsaw and a block to cut the lip off the straight side |
The fiber cement siding shear is the perfect tool for cutting PVC gutter |
Clamp the flat side of the gutter to the fence of the chopsaw if it's warped |
I finally had the long overdue inspirational thought, "What you need is a skyhook." So I went in the shed and got one. In this circumstance the skyhook is my big ladder with a standoff and a length of rope I use for tying boats to my car.
Skyhooks are real |
Safely remove the old bracket. I caulked the screw holes. |
In progress. Aluminum drip ledge moveable to ether side for access. |
I slipped the aluminum drip edge under the shingles above the chase. I'm going to call it drip ledge because it's massive. I secured the back piece of vinyl gutter to the wall with some sheet metal screws. I taped the slit in the end of the gutter by the hole for the penetrations. I also reinforced it with a piece of gutter cut from the same curved portion. My PVC cement was all dried up so I used the glue for the foam insulation. That product is the messiest glue I have ever used. I was so glad I was wearing disposable gloves.
I put the new insulation on the refrigerant lines. I glued all the joints unlike the original installer. I'm thorough that way. I'm hoping this batch of insulation will last a lot longer covered up. It's expensive.
The bottom of the vertical section is held away from the lap siding slightly. I shimmed it out from the ribbon joist of the house with a piece of PVC molding scrap I had in the shed.
Found a piece of PVC molding that fit just right |
Found a long sheet metal screw that looked good for going through to the 2x12 under the fiber cement |
Two screws at the bottom and one up top seem adequate for the vertical section |
I decided I needed some reinforcement at the top of this whole business so I went rummaging through the shed looking for something that would work. I found a bracket of unidentifiable provenance that looked promising. I modified it with a hacksaw and then hit it with some primer since it was probably some junk from IKEA and would rust if I put it in the shade and then breathed on it.
Primer just in case |
This end reinforced |

End capped with wood didn't want to fit tight |
The weather stripping stacked up at the back of the chase in the photo below is to stop the drip ledge from settling down so much it can't drain. On a sunny side of the house I would expect lizards to go in between the chase and the drip ledge, but in full shade they probably won't.
After I was done connecting the front and back of the clamshell together on top I ran two screws through the aluminum into the vinyl at the front edge. That secures the front section to the wall without depending on the back piece of vinyl. Also stops wind from lifting the aluminum ledge.
The end of the vertical section ends in a molded outside corner. I drilled a hole for the condensate line to come through. The post in the photo below is a reused gate post, thus the hole. The sole purpose of that post is to hold the hose bib. The footings around the posts of the house make it inconvenient to run the pipe up them. This existing post conveniently allowed the perfect amount of clearance for the chase.
I needed the end of this outside corner open to be able to work the hose bib handle. I shoves some extra foam insulation up in the end of the chase to stop critters from going exploring up there.
I secured the clamshell halves together with plenty of the stainless steel screws along the overlapping edges. I used about twice as many on the K profile side.
After I finished the chase I sent my brother photos. He told me I need a trap for my condensate line because wind washing makes biofilm grow. I rigged up something out of PVC parts I had on hand. It still drips into my reused toilet tank condensate catcher. If I decide I like keeping a little vessel constantly full of water right there I can paint it to match the post.

Stand back and admire the work |
I was happy when I was done and I could clean up all the PVC dust in the shed once and for all. I was looking forward to painting the lap siding, a job I could do listening to podcasts.
When I stood back and looked at that side of the house that big white thing on the wall just seemed unnecessarily prominent. I decided to paint more of the trim around the windows white, to draw the eye away from it. I guess it's better, I don't know.
Finally I replaced the hose hanger on the side of the house and I call it done.
It should be straightforward to take the chase apart if the refrigerant lines ever need to be replaced or serviced. I shopped for little plastic rivets to use instead of stainless steel screws to connect the halves. I didn't use them for two reasons. 1. They are stupid expensive 2. All HVAC techs have a screwdriver, but rivets might stump them. It's entirely possible this piece of kit will outlive me. If nobody thinks to look at the web archive to see how I built this they need to be able to figure out how to take it apart just by looking at it.
In conclusion: DO NOT ATTEMPT. This project came out fine. I didn't hurt myself. I didn't spend a ton of money. But it took me a ridiculously long time to do this, like three entire days and multiple trips to Home Depot. I guess if I'd had instructions I could have gotten all the stuff in one trip, but the figuring it out with the junk I had on hand was slow. If I'd spent three days figuring out how to rough in these lines inside the wall by bumping out the inside corner by the door to the bathroom it would have been a superior solution. But building a time machine to go back to 2005 was totally beyond the scope.

Regret for my Past Self: Correcting Caulk
When I built my tiny house by myself I used a Snapper Shear to cut the fiber cement siding. I love this tool because it's quiet and feels relatively safe compared to a circular saw with a fiber cement blade. But most production carpenters don't use this kind of tool because it costs over $300 and it's what Alton Brown would call a uni-tasker.
The video talks about the advantages of the tool, but leaves out the main problem. A saw leaves a sort of burnished edge. The shear basically works by pulverizing the product. It leaves the cut end very dusty. I did not realize at the time this was going to be a problem in the future, but I should have. Caulk can't stick to dust. Where the factory ends butt up against the corner boards the caulked joint looks perfect. But the ends I cut, the caulk didn't stick. Little cracks appeared. I should have washed the ends of the siding in a bucket of water and then let them dry before caulking.
The weather has been pretty good for working outside so I decided it was time to take care of this problem. I worked up a special tool for cutting the caulk at the corner board so I wouldn't go too deep and cut into the house wrap. I used my straight mat cutter with a 3" scraper blade modified to fit it. This turned out to not work any better than my regular utility knife so I'm not even going to put up photos.
The most useful tool was a dental spatula I got as part of a $5 set from PJ Tool and Supply, the same place I got some hemostats, also useful.
After I cut the caulk where it was very strongly bonded to the corner boards I got all the old caulk out of the joint.
I hoped the caulk would take most of the dust with it, but it sort of didn't. I could make dust come billowing out of the crack with a little brush I got at the grocery store by the dental floss. I washed the whole house down with a scrub brush and a hose after I opened up all the cracks. Then I scrubbed out each little crack again with the brush until I could not make any more dust come out.
I used Dap Dynaflex 230 caulk when I built my house. I like it. It was my fault I had to redo it, no fault of the product. But for the sake of curiosity I wanted to use a different caulk for the replacement. I did some research and found some people on the Fine Homebuilding forums like this stuff called Big Stretch by Sashco. I made a special trip to Lowes to get some Big Stretch since they don't carry it at Home Depot.

Here's the useful dental spatula |
I really wore down the end of this little tool |
Caulk didn't fail, just the bond to the siding |
I cleaned the ends of the siding with tiny brushes for cleaning braces |
I actually don't like it as much as the Dap. It feels kind of gritty. And it didn't fill the gaps as well. Some places it shrank so much I had to caulk again after I painted to make it look consistent. Time will tell how it does in the long run.
Tiny house benefits. All the caulk I had to replace only comes to 115 grams |
Because I'm a woman who has eyes I put down a drop cloth while I dug out the old caulk. I dropped the pieces into the same apron I use to pick blueberries. Any stuff that fell on the cloth, I scooped it up before I moved to the next corner. At the end of the job I had about 115 grams of wasted caulk. This is a data point without a purpose.
I was able to recaulk all these joints with less than one tube of caulk. I bought one gallon of paint and repainted the lap siding on three sides of the house. I still have over a quart of paint left. Tiny houses rule!
I repainted the siding on the front porch when I built the porch and turned the door around to swing out. That was 2013. I changed from flat to satin paint on the front porch then. So this time I made all the lap siding satin. I left the flat paint on the shingle siding and overhangs. The caulk seems fully adhered to all the joints of the shingle siding even though I cut the top edge of that with the shear to fit the angle of the gable. I would say it was due to not being in direct sun, but on the north side of the house the lap siding caulk joints failed and they are in the shade all the time. Perhaps larger joints don't exert as much pulling force against the bonded edges. My corner joints are pretty tight, but they are within the specifications of the product. I left bigger gaps for the shingle siding.
Oh, I just figured it out sitting here typing this. The expansion and contraction of a long siding run changes the size of the end gap more than what would happen next to a narrow shingle. Even the short pieces of lap siding between windows are longer than the widest shingle. Expansion and contraction is cumulative.
Next blog: The rabbit hole I went down to pretty up the lines to my minisplit and a new use for the siding shear.

Empathy for my Future Self: New and Improved Lab Entrance
I got a case of Titebond Polyurethane Fast Set Construction Adhesive in the mail two weeks ago. I was one of the first 50 people to email them after they talked about the product on the Fine Homebuilding Podcast. The shelf life on this stuff is only a year, so I was a bit worried about how I was going to use it up in time. I mentioned it to my brother and he said to bring it to him so he could use it between concrete blocks for a retaining wall around his pool. It needs to be high strength so he can compact the soil behind the wall and install pavers. I hadn't thought of using it for concrete blocks. Good idea.
The other day I missed the last step on my shitty back steps and hurt my foot. I mean, it was messed up. I looked up orthopedic treatments on WebMD and everything. Amazingly the ice worked great and it was all better in just two day. But while I was hobbling around with a walking stick for a day I really regretted that I had no handrails to help me in and out of the lab. Also I blamed myself for considering steps a luxury I couldn't afford. Were a couple dozen $1.69 cinder blocks more precious than my continued mobility? That's illogical. I resolved to fix them. I started with a dozen concrete blocks at Home Depot and started playing around with how to stack them around the doorway. I came up with something like this. By messing with the orientation of the lightweight blocks I planned to block all the openings so critters can't fill them with acorns. Which they have happily been doing for the past two years.
One one side I have to put solid blocks to cover the end. I made another run to Home Depot and got more supplies. I needed another whole row on the hinge side of the door and a lot of caps.
When I got back with more blocks I played with my arrangement some more. I had to work in something to hold onto. You can see in the above photo that I already have a cast aluminum handle screwed to the side of the Spartan to stop the door lever from slamming into the side and making a hole. Secondarily if you lift the door lever and drop it behind the handle on the wall of the Spartan it holds the door open. I decided to order some more of those same style cast aluminum handles since they were working well. I ordered two of the longest ones they have at McMaster. They cost around $20 each, more than all the stair components combined. While I waited for the UPS man I kept working on the steps.
I decided not to use the four old cinder blocks. They don't match the new ones. If I'm going to this much trouble it better look nice. But I was ready to glue caps on one side of some of the blocks. I did that in the morning so the glue could cure while I went to town.
I wanted to stick the blocks to the slab with something that would even out the surface so they wouldn't rock, but I may need to disassemble this whole thing one day. I'm not using the construction adhesive there. It's way too sticky and doesn't have enough body to fill in gaps. I started on the main section using up some rapid set cement I had leftover from a septic tank repair. I only had enough for the main rectangle.
The weird shape of the top step lets me grab the handle from the ground and then step right foot on the first step, left foot on the second step. Then I'm standing out of the way to open the door.

Unstacked blocks to be glued up. I cleaned off all the loose sand with a brush |
Puncture the inner seal on the adhesive |
Run a bead of adhesive around the block |
Place the cap on and twist it back and forth a bit. I had a bit of squeeze-out to clean off on the first one but I learned to keep the bead away from the outer edge |
After I finished with the glue here's how I saved the tube. Bamboo skewer and aluminum foil |
I poke the skewer through the foil |
Stick the skewer in and wrap part of the foil around the spout |
Break off the skewer and wrap over the whole thing |
Make a collar over the tube |
Put the tube back in the caulk gun so the foil doesn't get knocked off |
I used this method on a tube of this stuff after I secured a plastic door threshold at a client's office two days before the step project. The adhesive had barely even skinned over under the foil. I had to squirt out about an inch worth and throw it away. I will update this post when I try to use the half tube put away after this job. Two days definitely fine.
This product does not have an offensive odor to me. It's has the same lack of smell of other polyurethane glues. It's nothing like Liquid Nails construction adhesive that stinks like a silk screen shop. It's still good to have a lot of ventilation though, and wear gloves. It will stain your skin as bad as Great Stuff.
Mark Schroeder, the Titebond VP of Marketing, mentioned on the FHB podcast that they worked on the consistency so it doesn't keep shooting out of the nozzle when you put it down. I had no problem with that at all. Very well behaved stuff. I confess I probably have muscle memory for releasing the pressure when I put down the gun though. I probably automatically hit that lever on the back whenever I finish running a bead so I didn't really give it a chance to make a giant mess.
Squeeze out on the inside is better than on the outside |
For the rest I used some polymer modified thinset leftover from the tile floor. I keep it in a 3 gallon bucket so it doesn't go bad. I prefer working with it so much I'm not even showing photos of the other stuff.
After the steps were all done I left them overnight. I came back the next day to work on the handles.
Let the thinset slake while getting ready to use it |
Chalk outline around the blocks where I want them |
Move the blocks out of the way and put some thinset down. I used a large notched trowel |
I added a little bit of polyurethane adhesive between the blocks |
Here's how they come from McMaster inside a box inside another box |
I tested the enclosed screws with a neodymium magnet to be sure they were good stainless steel They gave me a lot extra. I still have 6 of these nice oval head screws |
The cast aluminum handle has a wallowed out place to allow it to go over this rivet. Rivet means strut on the inside which is good |
The top of the handle is not over a strut but it goes into the wood I added when I was installing the deadbolt. It gets longer stainless steel screws than the bottom of the handle |
I always put gutterseal under my aluminum to aluminum connections |
If a little gutterseal oozes out that's ok |
Clean up the excess gutterseal with acetone on a rag |
Here's the finished entrance from the outside |
I mounted the second handle on the inside of the door. This one turns out to be the one I use the most |

"Tetris" is not a valid step shape for a house built to code. But this is not a house. I'm not going to get a ding on the inspection report when I try to sell it. If I sold the lab it would require knocking these steps loose to put the whole thing on a flatbed and send it away.
I'm already used to alternating tread stairs because of the ship's ladder to my loft in my house. To me it feels natural. I asked my aunt with the bum knee to come over and try it out. She gave it the seal of approval. She appreciated both the handles.
If the climate situation keeps going this way I will never have a problem with freeze/thaw cycles. I don't think it's going to freeze again this season. There's a lot of thermal mass here too. When it does freeze here it's only for a few hours. I don't expect the underside of these blocks on the south side of the lab to ever get below freezing.
I've been using the steps for a few days now. I mostly come from the non-handle direction and go straight in without grabbing any handle. I like being able to open the door from the top step. Now that I'm ready for inevitable infirmity I will probably enter an extended period of peak health. I would say my enhanced grace and lack of clumsiness is assured, but that pyrex pie plate I smashed in the kitchen sink this morning says otherwise.
