Yost 204 1/2 main screw

[Penn31]

Hi,

I recently inherited a Yost 204 1/2 vice which was covered in grease and surface rust. Not knowing anything about vices, I reviewed a number of the post on this site and I can now at least identify the parts by name.

Ive cleaned and disassembled the vice and all the parts are in good condition but the main screw is broken and approximately half of it is missing.

Given the age of the vice I’m pretty certain parts are not available from Yost. Is this a part that is availble used or should I chalk it up as a learning experience and move on?

Thanks for any responses.

Can you, will you post a picture?

Couple options...

1.) Replacement new, may fit.

2.) Replacement used, people on here and ebay part out vises. There is a thread in the general forum for vise parts swapping.

3.) Make a new one. Unless you have access and knowledge of custom thread cutting, may not be cost effective.

4.) Graft a new section onto the remaining section. About the same as #3.

5.) Live with it. Like lathes, most vises see the most use in their first couple inches of travel.

If your Yost has a "meatball" nose on its spindle it was likely made by Reed. There are many parts available for Reed vises.

I’m new to the board and not familiar in posting photos, but I’ll give it a shot. As you see in the first photo quite a bit of the main screw is missing. So much so it does not attach to the main nut. At this point it is not functional.

The second photo identifies the model. The draw bar is in fairly decent condition other than there is a small crack at the very end of the bar. If Reed was the original manufacturer do you know the model that has interchangeable parts? Also, given the condition of the vise how much is a reasonable amount to invest to make it workable?

Reed PN is the same: 204 1/2

But it is NOT the current model which has the blunt spindle nose and the split retaining collar. It would be the earlier model Reed from about 100 years ago if you want the exact spindle for your repair.

I would not invest too much into your old Yost. The non-replaceable jaws reduce the value, and Yost does not carry the same recognition as others like Reed or Wilton. At most I would try to source an alternate spindle and matching nut. If you could provide some key dimensions of your spindle (length and diameter) as well as the nut (height, width, bore-to-base dimension) you might find someone to help. In fact, I have a spindle & nut from a late model Morgan 4-inch that might fit.

I appreciate your response, but the questions you pose far exceed my abilty to answer them in an intelligent fashion. I was an accountant in my former life so my machinist/engineering ability is limited to reading a digital caliper (lol).

I measured the remains of the main screw and the outside diameter is approximately .837 inches. The jaws are 4 1/2 inches wide and it appears to me the main screw would have been in the area of 16 inches. All that remains of the main screw is 6 inches. The main nut remains in the vise as I don’t see how to remove it.

I see a number of main screws for sale on ebay in the $35 range and there are a series of numbers associated with the listing. I suspect its the dimensions and other information pertinent to the screw, but it’s a foreign language to me.

Thanks for all your help and I appreciate your patience in responding to my limited knowledge.

dumbed down version
you can probably get a replacement screw if you know the Outside thread diameter , the minor diameter of the threads , the threads per inch ,the thread type ( in your case it looks like acme) and the overall lenght .
overall length could be longer & simply cut off to fit .
a machine shop could make a new screw too, we did it in high school. it may not be an economical way of repairing tho.

I just picked up a Yost at a yard sale for $20, not realizing the top of the base has a chunk missing (it had a piece of plastic wedged in there covered with dirt and looked solid--that's what low price seduction does to your evaluation skills, lol). still works but is likely just a parts vice, let me know the dimensions, maybe mine will fit.

How much did you pay for the vice mounted on the steel tube setup? That is a sweet setup.

$20. vice was like brand new, appeared to never have been used. it's my 2nd one, I got another identical to that a few years ago for $5. I figured the tube was worth what I paid...it was a good weekend for tools. that blue point 3/8 impact works like new, and I had a rubber nose cone off a HF impact that fit perfectly so I upgraded my HF for $1 to blue point, lol...

Is the vise you’re willing to part out a Yost 2041/2? As I mentioned in an earlier post I am not a machinist so my ability to take specific measurements is limited to what Ive already posted. Plus, the majority of the screw is broken off and missing.

I’m going to call Yost in the morning and try to speak to one of their technical staff members to find out if they can tell me what other Yost model screws, if any, interchange with the 2041/2. There are several Yost screws available on another site and one knowledgeable GJ member believes the Reed 2041/2 will fit.

Thanks for responding.

yes looks like a 204 1/2, everything is good but the base (non-swivel)

my mistake, it's a 104 1/2. pics of the slide and screw, and messed up base.
