I am a brand new member of this forum, so this post will likely not get seen by many. Hoping to get some guidance in restoration of the old ball vise (block) that I have had for a few years now.
As I took it apart, it became obvious that I am missing a piece of the puzzle, as it were, and perhaps even a piece of the vise! There is a largish brass collar or shaft that remains firmly attached to the upper half of the "ball". This brass part threads into the steel casting of the lower half, and evidently is supposed to ride on the lower ball bearing race.
I strongly suspect there is an upper bearing set INSIDE that brass part. The only rotational movement the vise currently has is on the assembly threads, brass to steel. I cannot for the life of me figure out how to get this thing apart!
Given the level of crud I have so far cleaned out of the rest of this tool, I figure the upper bearing is either seized or overtightened - but can't get it apart.....
If there is anyone here who is willing to assist with instructions on dismantling this critter I would mightily appreciate some help. LOTS of photos - hopefully this works.
