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 full 6"X6"X14" long blocks (Scrap from pole barn construction) Use 2 fencing staples and a length of 1/2" nylon rope with a knot (and staple) at each end for a handle. (6" is not ideally wide enough) If this stuff isn't available, one could purchase a treated 2"X10"X10' long and make 10"X10" blocks then attach rope handles. Remember when figuring the height you want; 2" isn't a full 2".
