There's one section of the tooling on this Hydroform I bought that shows up when folding alu. The rest isn't perfect but this one's the worst...been used to bend pipe or flatbar or something 
tried dressing it with file/grinder/sander but not much help
so.....any idea how much it would be to get the entire tooling (8ft..6 sections i think) machined back to a clean straight edge
or any chance of welding/dressing the really bad section? oir will the weld just break off/warp the tooling?
cheers
