Spiral_out Posted January 31, 2017 Share Posted January 31, 2017 I scored some tines at the scrap yard for about $40 and I'm going to make a post vise out of them. Since I don't have the equipment to put a hole in the tines for the screw to pass through, I was contemplating this design. The yellow tine of course needs to be trimmed a little! The white 1" plate underneath the nuts will be welded to the stationary leg (the yellow tine), then the nuts welded to that plate. Another plate will be on the top side of the nuts. The screw will just push against the movable jaw to close the vise. The hinge at the bottom will probably just be a U passing through both holes with cotter pins to hold it in place. The bent up plates at the base will probably be cut off unless I can find a useful way to turn them into a mount. Nothing is purpose cut in this picture aside from the movable jaw being trimmed. It's all on the table as far as actual dimensions and locations of welds. The screw is a 1.5" 8 TPI. That's a little slow so I thought of welding a large nut to the tip of it and making it a power assisted vice using an impact driver or drill. I'd need a wheel or removable bar to allow final tightening by hand though. I could also just get another screw, I already have several of these though. I could drift huge holes using a hole in the ground coal forge for a more traditional design, but I think that's a lot more work than it's worth to me at the moment. I also see there being an accuracy problem when I'm trying to get the holes to line up. I can buy an acetylene torch setup to cut holes, but that's not cheap. Buying a real post vice would be great, but I can't seem to find any locally. Give it to me straight, am I wasting my time with this? Should I bite the bullet and hire out someone to make the cuts? Should I bite the bullet and buy a torch? Quote Link to comment Share on other sites More sharing options...
