Dave51B Posted October 6, 2015 Share Posted October 6, 2015 Ha Ha , Alan......Don't ya think it should be working first ? Then I'd have to figure out how to divide all that royalty money with you guys...... To much trouble..... Dave Quote Link to comment Share on other sites More sharing options...
Dave51B Posted October 18, 2015 Share Posted October 18, 2015 Well, time for an update......no, I don't have any pics yet. But I think I've got the mechanics figured out the best I can. When I step down on the peddle (not permanent yet). It travels about 20" from the top of stroke to bottom. This will close the jaws 2". Which in my old brain figures 10 to 1 ratio. Sooo ,disregarding friction, If I put 200lbs. on the foot peddle I should get 2000lbs closing force on the jaws. Does that make sense? I do not have it mounted yet but just clamped in one of the other vices. The only 2 test I have done are.....putting my finger in the jaw test (ouch) and clapping a RR spike and trying to twist with a 12" crescent wrench. (couldn't twist it around).I'm waiting to find a suitable plate to mount this on. And, I think I will make it the same height as my anvil as that might be handy at some point. I'm thinking holdfast here. Maybe use one of Charles's fancy RR rail on end anvils for a post to mount it.Any thoughts, additions, or corrections ? And yes I know......without pics it didn't happen......I'll fix that tomorrow I hope Dave Quote Link to comment Share on other sites More sharing options...
Dave51B Posted October 19, 2015 Share Posted October 19, 2015 (edited) I'm going to try to add a short vid to this post to give an idea where I'm at on this. I have some more pics if needed. As stated before I'm not finished yet, so if anyone has any good suggestions, I can still change a few things.

Dave51B Posted November 18, 2015 Share Posted November 18, 2015 I'm 98% done. I just need to use it for a while to figure out how much of the screw out the back to cut out of the way. Also what to add for a foot pedal. I have some checker plate but I may go with an oak board. It might be easier on the shins..... Any questions or comments ? I have a couple of questions I'll post later. Thanks Dave Quote Link to comment Share on other sites More sharing options...
VaughnT Posted November 20, 2015 Author Share Posted November 20, 2015 Beautiful execution, Dave. Do you think you'll cut the pedal's arm length down, or is the added leverage really needed to get a good grip? What's the reasoning behind the stand's design? Is the rail section as tall as it is to help with some operation, or just because that's how long the rail was? I'll certainly be very keen to read your long-term report after a few months of working with it. Quote Link to comment Share on other sites More sharing options...
Dave51B Posted November 20, 2015 Share Posted November 20, 2015 Hey Vaughn, I would not say "beautiful" maybe functional ......My intent was to build a multipurpose unit. The rail and vice are both set to my anvil height. The pedal is just the length of the iron I had on hand. Final length to yet be determined. Same with the length of the screw and screw lever. Right now if I put my 180lbs. on the pedal I can hold my 1/2 " torque wrench stable up to 50 ft.lbs. of torque in the position shown. When moved to the outer hole in the screw lever, I can hold it to 85 ft.lbs. This should be more than enough to hold any item for hot twisting or bending I my need.....I think. As stated before I reserve the right to change anything at any time. I have to put it to work to determine how it will end up. Also I figure I have about $35 in this build, It may work great or may be scrap .......... To be determined...... Dave Quote Link to comment Share on other sites More sharing options...
Alan Evans Posted November 20, 2015 Share Posted November 20, 2015 How far out along the pedal was your foot when you did the torque test? If you bent the excess pedal metal into a curve to form two "P"s The left hand one reversed…it would give you foot access to the pedal from various positions to the side. Depending on the project in the vice and where you need to stand to carry it out... Alternatively, leave the pedal lever long and put a large weight or spring on the end to hold it down and add a lever to lift it up. That way, you lift it up, put in your work piece and let it down, trapping the piece and leaving you hands free. A hook attached to a floor ring might be another way of enabling you to be hands free….sorry I really mean "foot-free" but you know what I mean.

Dave51B Posted November 21, 2015 Share Posted November 21, 2015 Alan, I was basically standing past the cross bolt at the end. Not full body weight, had to keep balance with left foot, to pull torque wrench. Just from messing with it, I think a round pedal will work OK. It feels like I'll want to use it mostly from the left side, giving me access to the rail anvil and the flat plate better. Plus use my right foot for pressure. I still may add a notch system to the far side (right) to be able to just push the foot pedal away to lock it. I have got to get this set up to my little gas forge or something. Time to put it to work. That's the only way I know of to test it. So, anyone care to calculate how much jaw pressure it takes to hold a 1/2" torque wrench @ 50lbs. ?

ThorsHammer82 Posted November 25, 2015 Share Posted November 25, 2015 How hard is it to adjust the screw to change your jaw opening? Quote Link to comment Share on other sites More sharing options...
Dave51B Posted November 25, 2015 Share Posted November 25, 2015 TH82, Actually the adjustment is easy. Hardest part is to remember this is a left hand thread I'm using. I do have to raise the foot pedal to release the static pressure on the screw. I may end up adding some kind of grip surface on the screw box just for kicks. I did get a chance to work with it a bit, and so far so good. I was just playing with some small stock. A smith buddy of mine, checked it out yesterday when we met up to go to another guys shop to sharpen some plough shares, and now he wants to build one. Maybe Alan was on to something.........(still not sure how to divide up all that royalty money) Dave Quote Link to comment Share on other sites More sharing options...

But they would, wouldn't they? Alan Quote Link to comment Share on other sites More sharing options...

David Einhorn Posted November 25, 2015 Share Posted November 25, 2015 If you add a handle on the washer/ferrel, that looks like you could make the opening adjustable if you wanted to. However, with a foot operated vise, I doubt if that would be necessary, since your foot is what is opening and closing the vise. Quote Link to comment Share on other sites More sharing options...

Michael Cochran Posted November 26, 2015 Share Posted November 26, 2015 I spell it vice. Idk about anyone else but I know my spellin is always a little off. I think I spell some of the English words that's spelled differently between this side and that side of the world like people on the far side. I can't think of any examples now but I'm sure there's at least one. Quote Link to comment Share on other sites More sharing options...

Dave51B Posted February 29, 2016 Share Posted February 29, 2016 Well, after using this vice, anvil combo for a bit. I like the way the vice is working, but I am finding the "face" on the RR rail is to small. I'm leaving way to many hammer marks, because the face of the rail is smaller than my hammer face. The "fix" I'm thinking, is to cut out the rail and weld in a sledge hammer head on end, pretty much flush with the rest of the web of the rail. Any thoughts, or suggestions? Thanks Quote Link to comment Share on other sites More sharing options...

Alan Evans Posted February 29, 2016 Share Posted February 29, 2016 Well you have all the back up you need with the rail going down to the ground, so if you are going to weld a sledge hamer head on, I would put it on sideways and grind it flat to give you and even larger face. It may only be face hardened but will certainly be tough enough for a hot work anvil on the side. I would almost be inclined to weld on a bit of 2" plate of whatever size or shape you can get instead of the sledge head...mild steel will work fine and can always be re levelled with the Mig.

Dave51B Posted March 1, 2016 Share Posted March 1, 2016 Allen, I'll have to think on that a while. all my sledge heads are hex shaped with the flat side over the handle hole. Not sure I want a hole under the face of my anvil. I have ground the web of the RR rail some and want to keep the features I've added. If I weld the sledge head on, should I worry about getting it to hot? Also, I'm thinking I should get full penetration and not just tack the edges. Das, jeepers I'm only using A 2 lb. now....I'd have to go to a tack hammer. LOL Thanks Dave Quote Link to comment Share on other sites More sharing options...
