I would use 4 x 4 material placed cross to each other per layer, bolt them
together with ready rod or carriage bolts. cut them 8-12 inches long.
what part of the car are you working on? what kind of car is it?
you might be able to place a large bolt thru the stack so that it aligns
with a hole in the frame.

I have a small (=light) car that will need a lot of work done. It would be
easier if it was off the ground by more than the height those car stands
you
get at the auto stores can do.

So I'm thinking of making some stands from wood, and jacking it up in
stages
onto them. Has anyone done this, and are there any pitfalls (a
particularly
appropriate term) of which I should be aware?
