Reed 206R vise project

[Bigredford]

I've got a Reed 206R vise I had saved from scrap. The swivel base is welded solid. The moveable jaw is stuck. I had gotten the lead screw freed up about 4 years ago and that's as far as I had gotten.

First picture is when I brought it home.

2,3 pictures. The notched collar...does it unscrew out?

Last picture is the lead screw..I've sprayed a lot of PB blaster and dumped in a lot a of automatic transmission fluid in the space around the lead screw from both ends and it seems through but no luck yet.

Okay to start with, yes the collar (commonly referred to as a split nut) does thread out. There is a set screw just below the oil hole on dynamic jaw. I can't make it out in your pic so you may need to hit it lightly with a wire wheel but it's there. First hurdle is getting it removed.

Once it's out in a perfect world the split nut can be rotated out counter clockwise. On your vise that process may require some heat and a lot of patience. If your lead screw can be threaded completely out and removed it should make it easier to tap the split nut and thread it out or alternatively you can fashion a tool or spanner to fit in the slots.

Now here is the main problem I see. The leadscrew and handle assembly on these Reeds is normally retained by that split nut. The flange that would normally be present at the base of the handle assembly is absent. That means your leadscrew is essentially non operational and broken. Technically that missing flange is what applies the clamping force to the inside of the dynamic jaw when tightening the vise and also works to draw the dynamic back out when loosening the vise. You may actually find the broken flange inside once you get the split nut out. Either way finding a replacement handle will be a tall order!

Hmm. I wonder if the missing flange could be made and welded on? Then machined to fit?
