setlab Posted April 17, 2015 Share Posted April 17, 2015 (edited) Has anyone ever made a vice like this? Looks like it would be really useful for upsetting. If I had a scrap piece of that gear rack I think I'd be building one now, but that stuff looks kind of expensive for an experiment. http://azblacksmiths.org/plans/upsetting_vise.htm Edited April 17, 2015 by setlab Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted April 17, 2015 Share Posted April 17, 2015 That would be the rack from a rack and pinion gear set, what it came out of i have no idea but simulare parts cam me found in rack and pinion automobile front stearing units. Ot the can be fabricated a stedy hand could forge them with a small fuller i supose but a drill press, hacksaw and file would proobably be the way I would go. I would also think drilling a searies of 1/2" holes and bolting the ubseting block would work as well. The basic mechanics could be adopted to several uses Quote Link to comment Share on other sites More sharing options...
DSW Posted April 17, 2015 Share Posted April 17, 2015 Maybe I'm just being dense today. What's the point of the adjustable block on the rack? Quote Link to comment Share on other sites More sharing options...
setlab Posted April 17, 2015 Author Share Posted April 17, 2015 That adjustable block is for the end of the bar or whatever your upsetting to set on. So it has nowhere to move when hammering it. I suppose with a lot of time you could make a pretty nice substitute for that gear rack, I like the idea of stumbling across one at a scarpyard a little better though lol. Enco sells 1.5" square gear rack for about $150 for 4' in comparison. Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted April 17, 2015 Share Posted April 17, 2015 Upseting the top end like a rivet header, DSW Quote Link to comment Share on other sites More sharing options...
Michael Cochran Posted April 18, 2015 Share Posted April 18, 2015 I think it looks pretty cool. I may have to make it just so I can say I have one :) Quote Link to comment Share on other sites More sharing options...
DSW Posted April 18, 2015 Share Posted April 18, 2015 Ah! Now it makes complete sense. I was thinking more the cam action of the vise was clamping the rivet body like what happens when you use 2 pieces of drilled angle iron in a standard vise vs an upsetting block.

Jim Coke Posted April 18, 2015 Share Posted April 18, 2015 Greetings Setlab,Thought I would post a picture of an early upsetting Combo caulking vise.. The theory is the same .. Good luck on your build.Forge on and make beautiful thingsJim Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted April 18, 2015 Share Posted April 18, 2015 I think it dose both. It looks like it clamps the rod as well as providing a stop and suport. Quote Link to comment Share on other sites More sharing options...
Jacob Nothstine Posted April 20, 2015 Share Posted April 20, 2015 I was at a blacksmith event a few month ago and they had this vise for upsetting. Used it on a cup holder demo and it worked great. Been thinking about making one. Quote Link to comment Share on other sites More sharing options...
VaughnT Posted April 20, 2015 Share Posted April 20, 2015 Looks to me like the really important part of that vise is the adjustable rest for the workpiece to sit on. Other than that, it's not really doing anything that a set of jaw covers for any vise wouldn't also accomplish.Making the adjustable rest wouldn't be too hard because all you need is a series of holes that you can pin the rest in place by. The gear teeth are neat, but certainly not the only way to accomplish the adjustability. Not saying that I wouldn't love to have a dedicated upsetting device, though. We all need more tools!

DSW Posted April 20, 2015 Share Posted April 20, 2015 Jacob, that's a neat idea I might steal. I have a swivel head vise that got partially damaged when someone over tightened it that I haven't had the chance to play with yet. That would work really well for that purpose.

Dave51B Posted April 21, 2015 Share Posted April 21, 2015 Just thinkin" I got an old auto jack stand I may repurpose.....it has adjustable teeth for height ....10 ton, I think,....great idea....Thanks a bunch Dave Quote Link to comment Share on other sites More sharing options...
Quarry Dog Posted April 22, 2015 Share Posted April 22, 2015 I think I get it, but I'm not sure. So the hot end goes above the clamping dies? So it acts like a giant rivet header? Quote Link to comment Share on other sites More sharing options...
Frosty Posted April 22, 2015 Share Posted April 22, 2015 I think I get it, but I'm not sure. So the hot end goes above the clamping dies? So it acts like a giant rivet header?Yes. Heading a rivet IS upsetting after all.Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Quarry Dog Posted April 22, 2015 Share Posted April 22, 2015 Just seeing if I understood how it was set up. Somewhat off topic, but I always thought it would be cool to see a setup that would clamp either side of a section and upset toward the middle. I imagine it would function somewhat like a wagontyre upsetter that I read about in an old book/catalog that I can't remember the name of.

Frosty Posted April 22, 2015 Share Posted April 22, 2015 They're hydraulic upsetters. Grant Sarver was operating the one he used to make his tongs in the pic on his web site. I just spent some time searching for a "hydraulic center upsetting machine" without finding one but there are some really cool videos from folk selling the things.Surf in good health.Frosty The Lucky.

Quarry Dog Posted April 22, 2015 Share Posted April 22, 2015 I couldn't find one that was set up for center upsetting, but I'll keep an eye out. Quote Link to comment Share on other sites More sharing options...

arftist Posted April 22, 2015 Share Posted April 22, 2015 Upsetting doesn't have to be done via impact; simply pushing the metal when hot enough works. The issue is gripping the metal firmly enough to cause it to build up rather than slide.I built a device which bolted onto the jaws of an 8" Wilton vise. The vise jaws held one end of the bar and a set of tapered "grippers" held the other end, then a simple screw press advanced the ends towards each other. The use of a torch enabled easy duty in swelling the center of bars. It worked well for the job it was built for (a single window grate) but the mini single screw press didn't survive. I built it in vertical orientation out of habit; Jock Dempsey suggested that it should have been designed for horizontal use for added versatility.
