On the first day of Subtraction class, I was asked if I was afraid of using power tools. I was taken a bit aback; it hadn’t occured to me that I’d be afraid, and I would describe my feelings more like a deep-seated anxiety than fear. I wasn’t afraid I’d cut off my hand or injure myself, but I knew that my projects would likely go wrong– and my exercise did go wrong. Now that I’ve messed up, I do feel fine. It was the anticipation more than anything. Now I just feel that I’ve learned a lot.

The first step was straightforward– finding materials. I knew I didn’t want to spend any money, so I just salvaged some 0.5” plywood from the garbage.

I then measured out where I’ll stick in the pin, with a weird twist. The ruler I used had apparently been imprecise, the product of another itper on the laser cutter. My original measurements became this unhappy face.

I then loaded the circle jig and the router bit onto the router.

A long time ago, in high school shop class, I had used a drill press before, so using it wasn’t as intimidating as the other tasks.

The sad, imprecise face is still sad, though.

Then, it was time to actually use the router. I had a little trouble securing the plywood, as I didn’t realize I would want flat screws. The trickiest part, unexpectedly, was adjusting the depth of the head. It took a little finesse sometimes.

Then the circular cut was done! It was a little imprecise, but I was too content with my work to think to fix it. In future projects I will know better.

Then came time to measure out the straight edge of the cut. Because I had been imprecise earlier, I changed my mind about where I needed to cut. It’s less certain whether the piece would come out if I had followed my original plan.

Cutting this was very straightforward.

But the piece is now done, despite the imperfections.
