Where do I get jackstands with a flat base?

[Maengelito]

i just had a 2'x2' piece of wood cut into 4 smaller squares. that works fine as well. i'd like to go the welded route if i knew how to weld, but wood works fine too

If you want to cut some steel for the bottom of your jacks I'll bring the welder to the track and weld them up for you sometime. I can't weld any thicker than 1/4" though, but 1/8" should be plenty thick for something like this, best idea is to match the thickness of the jack, that way even heat will go into each piece.

its not too big of a deal. the wood works well and i honestly dont need flat bases on a concrete garage floor. i also dont have room for jackstands and a jack in the miata so i dont bring them to the track anymore. i appreciate the offer though chad
