chassis jig design

[1meansnake]

Almost there.. there was minimal warping with this method, although there was a bit on the short overhanging end pieces. Will have to reverse this by some heat and force on the ends. Nothing major though. Had to brush up on my MIG skills as I have only been using TIG for while now. TIG would just make the warping much worse.

The braces are thinner walled than the main pieces - just extra material I found sitting around. Should have this up and running under the car within the week.. can't wait. The Carr-Lane leveling feet (part CL-8-SLF) work perfect.



Also set this up so I can put an 1" thick or so sheet of plywood in between the braces to drop the plumb bob on. A 4x4 sheet will fit exactly in between the two middle sections.

I don't understand how TIG would make heat input worse than MIG????

You have a foot pedal to control heat with TIG. Care to explain???
