Made this for fun, and for minor work on my bike. Bought the jack on sale for about $26 last year. Had a square 1/4" plate welded on top the jack. Had some plank and high density plywood laying around. 2 lag bolts mounts it to the bottom plank. 3/4" socket is easier and faster than the one that came with the jack. A small carry handle and it slides right under the bike.
