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 cut 2 15" long pieces from a railroad plank. These planks are heavily treated, so no rot. I screwed a handle on one end of each, for ease of carry. Been using them many years, still in great shape.
