After making a simple zero clearance insert with my new Shapeoko 3 XXL, I wanted to try something else fairly simple but slightly more challenging. Ever since I installed our Ecobee 3, I’ve wanted to replace the white plastic plate that goes around the thermostat. But building something that has a nice shape and fits well would be a challenge so I dropped it in my “if I ever get a CNC” project list.
To get started, I grabbed a photo of my model online (there are a lot of slight variations through the years!) and traced around the outside in Inkscape. I used some cheap 1/4″ MDF as test pieces on the Shapeoko and after 4 attempts with tweaks in between, I had a good fit around the thermostat.
Then I added a lot more complexity. Instead of just being cut out, that original hole that I designed became a pocket in the material. I added in a hole all the way through the back for the wires and two more for the mounting screws to pass through. That all went pretty smoothly but the tricky part was making room for the vent on the bottom of the thermostat to exhaust air but not making the vent bigger than it needed to be. I’m still not convinced I have that designed as well as I could, but it got to the “good enough” point after 4 attempts in 3/4″ pine.
For the final cut, I milled up some walnut and put it on the CNC. The first attempt went ok but ended up failing near the end. Despite slowing down the program to account for hardwood, I think I was still a little too aggressive and I might have had the router carriage adjusted a little too loosely. The second attempt went slower (about 35 minutes instead of 20 minutes in pine) but it came out perfectly. I finished up with some sanding and routed a chamfer around the outside using the router table. I finished it with a coat of boiled linseed oil and mounted it on the wall.
This project really made me feel the value of the CNC. It was awesome to tweak my design by fractions of an inch and have a completely new part in under half an hour. It’s a lot easier to experiment than if I was trying to do this all carefully by hand.
Fun fact: about 80% of the way through this project, I was installing a test plate and when I put the thermostat on, it didn’t turn on. Of course this was the last thing I was doing before going to bed. After some panic and opening up service panels on my furnace, I found a fuse that had blown. The next morning, I called my favorite HVAC expert, and verified that replacing the fuse would work. After a quick trip to the store and $2, I was back in action, but boy was that a cold and stressful night! Always turn off your equipment before working on it!
Big Decisions
The first was “Where should we send Elijah to school?” Proximity to school through grade 8 was a big reason why we bought this house. It would be so nice to just walk out the door and be at school instead of dealing with traffic and commute time. But on the flip side, we’ve really been enjoying our experience at our church preschool and kindergarten. Tyla and I both attended WELS grade schools and we have reaped the benefits both spiritually and intellectually. There are some great WELS schools in the area but they are too far away to make them work.
At the marriage retreat last fall, we talked to a Pastor from our area who mentioned Zion Lutheran School up in Lake Stevens. It’s an LCMS school and after visiting it, we felt like God was nudging us in that direction. It will mean a ~30 minute commute one way to school, but it’s doable and we’re going to give it a shot. We don’t love it as much as we’ve loved the WELS schools and we’ll need to pay closer attention to the doctrine he’s taught, but we’re going to give it a go.
The second big issue arose after I popped my head up into the attic for my annual (well… less than that because I’m lazy) check of the crawl space and attic. I discovered obvious mold. I stared at it for quite a while before acknowledging that there was no way to ignore this and hope it went away. Thankfully, we found a contractor who has been great to work with and the remediation plan is well underway. We caught it plenty early so that no structural damage was done and there were no health concerns. Once we finish the remediation plan, there will be a lifetime warranty that gets transferred to future owners so I feel pretty good about the situation.
During the decision making processes, there was no avoiding the fact that both choices could have dramatic and long-reaching effects on our future. The school one was obviously more important, but making the wrong choice with the house could easily cost us tens of thousands of dollars in the short term or when we sell the house. Through it all, my prayer was always “Lord, you know the path I should take. I feel like you’re leading me to this choice. Please make it obvious if I’m supposed to choose something different.” God has it all planned out for us and it can feel like a shock when he reveals some of the bumps to us, but there’s comfort in knowing that he’s going to make it all work out for the best. (Romans 8:28, Jeremiah 29:11)
