Anyone know where I can get a replacement part for a very old woodvice? It’s a 1904 Rock Island Mfg vice (no longer in business). It’s missing the threaded nut at the base that the main screw turns into. I imagine that the part is similar or identical to most of the vices of similar design. I’d just have to make sure the threadcount was the same and could probably modify a similar part to fit. Attached is a pic. Thanks

How about showing the nut? If it's a standard acme thread nut, it should be findable.
I suppose once he finds one he can show it. :-)
Well that's the problem, the nut is missing, so I'm not sure even what it looks like. You say it's an standard acme thread nut...what does this mean?

Life is what happens to you when you're making other plans.
When your ship comes in... make sure you are not at the airport.
Thanks guys. Learned something new today! I never heard of an Acme thread. Hopefully I'll find that part and my $10.00 vice will be shined up and working soon.
You could try a good hardware store that sells threaded rods. Acme threads are used in jacks and a store that has the rods will have the matching nuts.Note that a nut will cost more than $10. I paid 8 euros (call it $14) each for 12mm ones. The nuts are likely to be cylindrical, are made of tough stuff and more difficult to cut than run-of-the-mill steel.If you need to do any welding you need specialist rods.
Well guys - it looks like I'm stymied on this one. That threaded rod is a 1 5/16' diameter, a dimension that hasn't been used since WW2. Getting a nut of any sort, much less a vice type half nut is impossible unless it's custom made. The cost of this is way more than a new top-of-the-line vice. Even getting a new matched set acme rod and nut is way too expensive.
None of the existing vice manufacturers have anything close.
Unless I can find this part in some auction or junk bin, it appears that my $10.00 vice is now a boat anchor, or perhaps big paper weight. Anyone want to buy a nice old vice? It only needs one part ;-)
Thanks for all your ideas.
Put it in a garage sale. Somebody not as enlightened as you are will give you $10 for it. :-)

Why not custom made. Isn't it a pretty easy thing for a machine shop to turn out? Perhaps a hobbiest machinist?
steve, the amateur machinist was exactly what I was gonna post...

Good idea. Perhaps a high school machine shop might be a good bet. A normal shop would charge well beyond the cost of a new vice.
The next trick is to find out exactly what this part should look like. It would be nice to get the full quick release functionality.
You could make one out of wood .
Ah, I shoulda read closer. You might do a search on "acme nuts" on http://www.mcmaster.com. You may be able to get some ideas from that.
Many vices use a twin or double set of threads , you can look on the end of the threads and pehaps see the two .

I have a couple of the columbian wood vices that look very close to what you have in the picture. I think the thread pattern is similar. The nut on the vice I have is floating one.
I think you might find what you need if you go to the site above and see what is close to your vice. They have a phone number and contact information.
Hope it works
