Floor jack pad

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.

Yup, in a nutshell.
Here comes another, logically connected.

Awh so you got your post in while I was typing
I like your solution your are correct steel on steel without some means fo keeping it from slipping under load is always a concern even when just relying on the jack to hold a load long enough to place a safety stand.
I currently don't have a floor jack they don't work well on sand but I have on occasion replaced the rubber suspension pads on older Mack trucks the pads make perfect jack pads as they have a steel plate bonded to 1 side of them with a cylindrical protrusion of about 1 /12" in diameter and 3/4" high On the last floor jack that I had I welded a 1/2" plate with a hole to match the protrusion to the jack plate then Sliced the rubber pad down to about 1/2" thick it worked great at least until somone wanted to borrow the 5 ton jack to lift a 10 ton load Sheesh that is why I had a 50 ton bottle jack for those too heavy to lift things.

FWIW, the proper name for what you're calling a "jack cup" is a saddle.

Thanks. From now on, I'll recall with this mnemonic; when I jack (c)up the chassis, use a saddle.
