reefera4m Posted August 31, 2010 Share Posted August 31, 2010 reefera4m The original press was made from scrap that I had lying around my shop, that scrap happened to be 2” square tubing. You cannot tell from the graphics, but all of the tubing wasn’t even all the same wall thickness. The beauty of this press is what I presented and offered to the group was a concept; ever one that has made this press has added or subtracted their own ideas. Every press is just a little different, everyone trying their ideas and then presenting the ideas to the group and making the concept not mine but ours. Try your ideas and then let us all know what you found out. Just remember - its little, but it still exerts 20 tons of pressure on the frame and components. Twenty tons is enough power to hurt you - really quick. I always make test runs on a new press before I get my face and body in harm’s way. Test the press then check your welds and determine if your bracing is deforming or moving off center. A bad weld or a frame that is not square will fail. I suggest stick welding; I don’t trust mig or wire welders they just do not seem to penetrate deep enough. Your experience may be different. Good luck and tell us what you find. T. A. Toler Thanks for the feedback - hard to tell your press was made from scrap! I've been making/fabricating this and that for a while and I've learned (sometimes the 'hard' way ) , to test and validate. I'd planned to use the same 2" square tubing (1/4" wall) since I already have enough for the uprights. Since I don't have a stick welder, only a 220V Millermatic 175, I've learned to make some accomodations. While it will weld 1/4" plate single pass, I find it produces the best welds if I bevel the ends of the work pieces. Cranked up to near max for .030 wire, you still have to be diligent in your welding technique. But I've successfully welded a 12,000 lb dead lift receiver hitch with this machine. To be sure, I had the prototype tested to 15,000 lbs and then cut it up to further evaluate the welds. That taught me more about making proper welds that anything up to that point. I've also been concerned about getting the pieces square and plumb so that the bottom ram bar moves up and down smoothly. To that end I'm first fabricating a squaring jig to hold the pieces in place. I've tried corner magnets, metal squares, etc but I seem to inevitibly pull the pieces of kilter when welding - even though I tack weld first. I have a friend that build the type of jig I'm making and it has a number of heavy 'C' clamps to hold the pieces to be welded. Once clamped in place it's almost like its already welded - you can't move the pieces with a hammer! I've also got a few ideas for some options. When I get it completed I'll post them. I'm almost tempted to wait a few more months to build my press - there are so many grat ideas that constantly show up that I'm afraid I'll miss something too good to leave out:D .
