Floor jack pad

[Toolmaker51]

A recent buy, this surprisingly good HF dual piston lift. Like many, I use a floor jack, occasionally for other than a particular automobile. Main driver is a full-size FWD, most of front is one big flat heavy plate. Strong enough for jack but nothing to 'bite' and prevent slipping. Working without help or anyone nearby 99% of the time, cautious about being in jeopardy.
So this rubber pad is attached to a pair of welded spacers. The combination extends beyond prongs of the normal jack saddle. Milled saddle just enough to be a flat bearing between castellations [something else microsoft is unaware correct spelling] for the longer plate. The smaller milled to fit remaining space, bears on bottom of saddle's cup, all intended for minimizing deflection of rubber to frame member.
