Now your comment makes way more sense. I was very about what you were saying.
I see what happens when you miss a thread around here.
Funny, I have both of those jacks and some other similar ones. One I have almost exactly like the one on the right quit working last week. I noticed bearings falling out of it, got a magnet and picked them all up, took it apart, it has small ball bearings in the threads and a little U pipe screwed on outside the threaded block letting the bearings move back and forth in the threads and return end to end. Who knew? One of the screws had fallen out and let the bearings go. Shortened a new screw for it and loctited them both in, should last longer than I do now.I've always thought someone needs to make a kit to convert a high-lift jack into the same geometry as an old school bumper jack for those kinds of uses.
They existed along side each other for the first 50yr but the latter died out with no good replacement.
The one above for the center punch.
This one for the scribe:
Been using these punches for years...
