Nothing fancy here. Long ago like 4-5 years, I made this tri square specifically for my drill press. I know the light colored wood is Maple but not sure about the darker one. I think it's Walnut. It's assembled with Maple dowels. It's pretty accurate when I hold it next to my machinist square which is dead accurate. In the first photo I'm holding them up in front of florescent lights. No gaps at all. Cold and hot weather hasn't changed it a bit which surprised me a bit. I was thinking over time it would change sitting in my garage cabinets but it hasn't.
Thanks Barbara. I don't have much Walnut. I thought it might be torrefied maple which I have a fair amount. However.. Torrefied Maple has a roasted smell that unmistakable. I agree... it's Walnut.
I made one in HS shop class. It's 54 years old right about now. It never did quit moving, so one day it was good, the next. not so much. I tried to use it for real work back in 1971, but it just lacked even against a POS square from the lumber yard. As I picked up better tools, I found a big clunky machinist square that is dead nutz, and it hasn't budged a bit since I bought it. At my last shop I had it hanging on the wall, since we moved 12 years ago, not sure which box it's stuffed in now, but some day it will pop up. For my square at the tool, for just end cuts, I mostly use those plastic squares you see everywhere. If a person couldn't afford a great machine square at each machine, they are pretty darn accurate, and that plastic of the heavier class stays stable, unless you get it too close to the heat gun. DAMHIKT.
