mlinn77 Posted December 5, 2016 Share Posted December 5, 2016 Hi, I picked up this Yost vise it's 6" opens to 10" I got everything working has a broken mounting bracket. I've heard of Yost I can't find anything on dating or on this model # it's a 78, and I was curious on what that knob on the back is for looks like some sort of gig hooks to it. Any info would be appreciated thank you. Quote Link to comment Share on other sites More sharing options...
C-1ToolSteel Posted December 5, 2016 Share Posted December 5, 2016 All I know about Yost is that they can be really expensive. More than some Wiltons. Great find. How much did you pay for it? Quote Link to comment Share on other sites More sharing options...
mlinn77 Posted December 5, 2016 Author Share Posted December 5, 2016 Paid 220 including a 120 lb Colombian anvil that's in decent shape. The vise was apart and wouldn't swivel a little heat, patience and grease works like new. Quote Link to comment Share on other sites More sharing options...
Jim Coke Posted December 5, 2016 Share Posted December 5, 2016 Greetings 77, The pin on the top should come out to allow the rear section to pivot. Great vise for uneven gripping. Forge on and make beautiful things Jim Quote Link to comment Share on other sites More sharing options...

Forge on and make beautiful things Jim Do you know if that pin is spring loaded, or how it doesn't come out with you pull it, it's really suck I'm trying to look at my options on how to move it. It's soaking in penetrating oil now. Quote Link to comment Share on other sites More sharing options...
Will. K. Posted December 13, 2016 Share Posted December 13, 2016 On my Prentice swivel jaw vices the pin is tapered and is held in by the taper fit. I imagine it is similar with your Yost. The one I've removed the pin on my father carefully pressed out the pin from underneath using his shop press. I was worried it was going to break. Drilling it out would have been a safer option. I had the machinist where I work turn me up a new pin with a bigger head and a hole going thru it perpendicular to the axis of the pin for easier removal. There not as stout as a fixed jaw vice of the same size, I've seen pictures of several with the back jack welded/brazed back on. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted December 13, 2016 Share Posted December 13, 2016 Heat the body and chill the pin? Hopefully not an excessive amount either way... Out here we would leave it in the sun during the day in the summer and then try an icecube for about 100 deg F differential. Putting it in the kitchen oven set on low has also been done if one is un partnered or has no fear of pain and death! Make sure there is a drip pan underneath it to catch any grease or oil residue...

mlinn77 Posted December 13, 2016 Author Share Posted December 13, 2016 Haven't tried the hot, cold method yet, I have tried just heat, right now it's soaking, I'll give some more patients then I'll look into drilling the knob was pretty boogered up before I got it.
