Yes sir.Is that the pheumatic corner notcher you mentioned to me?
Nice box BTB!
Welded. If it's 16 gauge or thicker I TIG them. But this was 18 gauge, and I'm not as good with a TIG as I used to be. So lots of stick out, and just go slow and stitch them together. A few passes on the belt sander and wire brush, and I'm done. Lots of fun.
