chassis jig design

[raustinss]

Hey guys as a professional fitter /fabricator I've made a living on a 4x8
1" thick table it had 3"angle legs with spreader bars obout a foot from
The bottom and more about 5" from the underside of the plate surface
Keep te legs in about 4 " in on the sides and about 18" on the ends . Now
If you can afford it machine the surface "flat" and tap 1/2" holes all over the
Plate . Roughly a 6" grid . These holes will allow you to bolt on "risers"
And hold downs . These can be welded (tack) to the car and bolted down
To hold everything in place while you work. DO NOT rely on gravity to hold
Steel and shims as steel moves when you weld and hammer. A light coating of oil
Will prevent splatter from sticking and rusting.the problem with I beams which are
Actually called wide flange is they aren't true the web (center) can be off center
And they can twist . Tubing is really nice it is at least nominal . (diamenstionally) true This makes measuring easier . I personally would make mine out of tube or the above
Table just make it 10'-12' long. The benefit to a "plate" surface is you can write and draw on it and have somewhere to place your tools.
