my legs come way down does anyone build a set of blocks to put under jacks. someone told me it is unsafe because it could roll off. I am thinking of cutting 2x4x12" and make them about 8" tall
I use 2x4's. about 8" long. 2 goes side by side then 2 more side by side the other way.....screwed together....then 2 more going the opposite way which are screwed to the others. Makes an 8" square block about 4 1/2" high.
