Thanks for all the replys and insight guys. I'm back to rethinking options though. The material I'm using for the floors and fire wall is 17 gauge stainless and most of the machines I've found are onlly rated of 18 gauge (I'm pretty sure they are only talking about mild steel).

For grins yesterday I built a die and tried to hand form some beads and got a pretty good idea on just how tough the stainless is. Even using my press to try to form a bead didn't work out.

It looks like my options are either finding someone around town with a roller HD enough to form the beads (I'll be checking this morning) , using lighter metal, heating the area I want the bead just prior to running it thru the roller (which I think would end up causing a lot of warpage), or building a frame work under the stainless.
