Nice looking square. I also made one, a little larger like a framing square, but I've not trusted it much, just hangs in the shop.
Thanks Oldtool! For a while I didn't trust mine either and it sat there looking pretty, unused, and looking lonely. Every now and then I'd checked it and always find it accurate and stable. Then a few days ago I checked it again and still.. it's good. I'm using it now mainly on my drill press. It finally has come into use.
