I'm making this post to help others in the future who may need to find a part for their Vintage quick release Columbian woodworking vise.
I found myself in this situation recently after having bought a vintage Columbian Model 9-R quick release wood vise (10” wide jaws) at a garage sale.

When I got it home and took it all apart, I discovered that the threads on the bronze "half nut" that engages the steel acme screw were so badly worn that the nut would slip and disengage from the screw when tightening. The original part was made of silicon bronze and was designed to be sacrificial (i.e. to wear out before any damage was done to the threads of the acme screw.) But the challenge was where to obtain a replacement.

Columbian Vise & Manufacturing Company (Cleveland, Ohio) was eventually bought out by the Walter Meier holdings company. Calls to them resulted in the answer that "we no longer have any parts for these Columbian woodworking vises." But fortunately, I found a post on another online forum that the Milwaukee Tool Company (Milwaukee/Morgan vises) still makes a very similar model of woodworking vise that uses a similar bronze half nut.

After checking their website http://www.milwtool.com/v_wood.htm speaking with their sales department and getting a copy of the parts list for their vise, I went ahead and ordered two replacement bronze nuts (one to use now and the other as a future spare). Cost was $40 ($20 for each nut) and $10 for freight. Although the part is not 100% identical (1/8” shorter) to the original Columbian part, fits just fine and works in the vise. So if anyone here is needing to get a similar replacement part for their vise, know that one is currently available. Hope that this will help somebody.
Copoliot, why did you take down the post. Looking for a half nut for my vice
Gravity is important. The vise quick release may not work if upside down.Not completely familiar with how the nut works in the vice and if it floats or gravity plays apart, like other similar ones that I have. Any help is appreciated.
Wasn’t sure if you would get notified of my response so I put my reply here. Thanks.Gravity is important. The vise quick release may not work if upside down.
The two I have worked with will not work if upside down, where you can see it easily.
All the quick release WW vises I have used or worked on have this function. Jam it closed by pushing, then you get about 3/4 of a rotation (270⁰) of clamping effect.this type of clamp with a quick release is not meant for the handle to turn several rotations with the half nut staying engaged each time. It is meant to slide smoothly into the work piece and then engage the half nut for a partial turn to lock the piece in.
My Cardinal Speedvise DP vise seems to work this way, too.All the quick release WW vises I have used or worked on have this function. Jam it closed by pushing, then you get about 3/4 of a rotation (270⁰) of clamping effect.
You don't get to crank 2-3 revolutions.
