I'm in the process of contrsucting my own frame table. I'm trying to figure out the best way to come up with some leveling legs. Any ideas?
Any decent industrial supplier will have swivel adjusting feet for cheap. Cheaper than you can make them. Weld a tapped block onto the frame,screw the leg in,tight the lock nut.
Couple of years back the local speed shop loaned me their funny car frame table. It was constructed of 6" I-beam for the frame and supported by six 3" square tubing legs. Each leg had a 1/4" plate with a 1" nut welded inside, on center. The plates were drilled 1" on center like you'd expect so that 1" bolts could go into the plates. 1" bolts with nuts spun on were installed in each plate and the frame table weight rested on the bolt heads. Using a digital level - a bubble level works just fine - it was easy to get the frame table level and the weight of the frame table kept it from creeping or moving. I used the accurate, flat and level frame table to build the 32 frame for my 31 roadster, installed front end components including radius rods, installed the narrowed rear end and did the engine swap with the frame up on the table. The engine/trans were removed separately with an engine hoist and the frame/ wheels and all were brought down with the same hoist. All done by myself. In fact, at several times during the build the body was installed for accurate fitting. Since it was a roadster, that made life easy. A coupe may have fit under the garage ceiling, but it would have been a tight fit. The speed shop owner offered to sell me the frame table at one time, but I declined. Then I realized it would make a helluva work bench if it had a removable top on it. By then, the speed shop owner had decided to keep it since there would be room to store it in his new shop addition. Storage . . . the bane of many a hot rodder and the letting go of some cars we should have kept....
you could look at adjustable scaffold feet or mobile home jacks for parts I built mine very flat and and sturdy but on wheels, I don't use a level on it much but reference off the table itself when I do want to use a level I place shims under the wheels, plywood, plate or sheet metal
