Thanks guys.
My problem has become finding the right materials. I know Nick Wheeler used Schedule 80 pipe. But when I go in to try and find pipe and a wide flange or I-beam, I can't. I went to the junk yards, and I went to the metal distributor in town and the didn't have pipe that would fit "nicely", meaning there was a ton of slop.
It doesn't matter what the schedule pipe is to me, any more.
I just need the vice to be 2" - 2.5" inside diameter. And then go from there. Same for the wide flange.
So I am working on just finding what I need then getting someone to weld it together for me. But so far no luck on materials yet.
