Oh yeah, I went looking for 3/8-1/2" round SS to make rod holders. Found 3/8 sq SS so I got maybe 15'. It's just been laying around so just for giggles I tried it as a guide for the PP50. It 'rode' on it perfectly. Set it 5/16 from the intended cut and it just zips right through...and being square it clamps easy. I welded a 90* piece so I can clamp it away from the cut. Neat stuff.
