Would something like a brake cylinder hone clean it up well enough to
work for a while?
I have a Sears 3 ton floor jack that is starting to fail after about 18
years. Wish I knew more about fixing the things. The jack saddle on
the thing is so dang high, it has trouble getting under most new cars
anyway. But I worry a new low-profile one will just expire quickly
anyway. Hmmm.
