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.
