Yost #1 Patternmakers vise

[Joe Huld]

Picked up a pretty nice Yost number 1 patternmakers vise today in great shape missing only the handle and the under bench bracket. The handle is easy enough to replace with a piece of pipe and a couple of caps but I'd like to replace the bracket as well before selling it. I made a replacement bracket for an Emmert years ago and may still have the sketch but if anyone has a picture of an original Yost bracket assembly I'd really appreciate it.

I'd like to see the replacement bracket drawing for the Emmert - I need to build one for mine.

I have a Yost apart on the floor right now, had it for a while and it's waiting to get in the parts cleaner. I'm a computer ***** , however l'll get my son to take pictures and post them, it's a 16" version pattern makers vise and all the parts are there. It will be a day or two as he is out of town right now.

Sorry for the long delay in reply. I never did find the drawing so had to reverse engineer one and did not bother to do a drawing this time . The attached pics show the final version. My first try looked a bit more like the original but I found that it did have some flex and was much harder to fabricate so I came up with this one which was easier to make and hopefully will be rigid. To avoid the problem of milling an 18 inch long slot, I made a long "U" from 3/8 square and welded a 1 1/2 long piece of 1 1/4 x 3/8 stock and drilled I with a 5/8 hole to fit the pivot stud on the vise. The under bench bracket consists of 2 pieces of the same 1 1/4 x 3/8 flat stock plus a piece of heavy wall tube about 1 1/4 OD with a 1/2 inch ID that I drilled to 5/8. The base is 8 inches long with 1/2 inch holes 1 inch from each end. The "V" shaped piece started out 10 inches long and was bent to match the OD of the tubing and was welded to the base. I then welded the tube "boss" to the "V". This was intended to fit my Yost but a friend needed one for his Emmert so I made 2 at the same time. I'll let you know how it works on Rons vise.

Thanks for the explanation Joe. I’ll look forward to hearing how it performs.

Anyone here have any extra original parts for the above G.M. Yost?
