Picked this up recently, it needs work! Not too much I hope but once you start...
The known issue is with the vice and it turned out to be quite an oddball problem.
It has a half nut!
At first I thought it had worn out but closer inspection revealed an odd looking "button" which was siezed and displaced from the spring and the remaining threads were choked SOLID with crud.
So I did a quick clean up to see what's what.
Here's the button which is now fitting fully into the hole and not siezed. It really hardly seems to reach the thread at all and certainly does nothing to "retain" the thread.
The key is the shape of the carrier which can rotate in the cradle above. When it rotates in one direction, the stub hits a roll pin on the cradle and wedges the thread into the half nut
Seems like an odd way to do it but it works
Wind the handle in and the thread "picks up" grips and clamps. Release the grip and it acts like a quick release and the moving jaw can be shifted by hand.
That's as far as I got with it. There is still an issue with pitch. It works perfectly sometimes and sometimes it picks up an odd pitch and basically sticks. I may need to clean it more thoroughly, it might just be an odd bit of crud somewhere which judging by some similar crusty deposits, can be as hard as concrete.
Not planning on doing a full resto yet, I just need to de-spider it before I fire it up and start using it for other projects.
I would say the chances are, I'll pretty much have to rip it apart to clean all the bearings and guides etc. so it may end up being a mini-resto anyway...
