Members dikman Posted Tuesday at 03:11 AM Members Report Posted Tuesday at 03:11 AM I made another die bending jig. I had the idea to make one with a simpler linkage so just had to do it. Unfortunately while the linkage looks simpler it took a bit of messing around to get it to work, and the angle of the handle is too high which meant I had to put a hefty downward bend in it to get it to a comfortable height. I might re-make the handle linkage as my original idea seems to work better. The other difference is the push slide, the original square tube sliding in a square tube has a bit of slop in it, the rod version is quite a snug fit, but it meant attaching the fittings to it was more complicated. I now know how to make an even better one - but I won't as it will require too much machining and there's nothing to be gained.

I am going to assume you made the base larger on the new one as you had the metal hanging around. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
Members dikman Posted Tuesday at 05:48 AM Author Members Report Posted Tuesday at 05:48 AM Yep, I didn't have any more of the smaller channel iron, this one was about the same length (so I didn't have to cut it) but is considerably heavier (it's been sitting in my forge for years!). I sat down for some time staring at the handle/pivot area and came to the conclusion that the design isn't very efficient when it comes to applying force and transferring it to the slide. So I'm redoing it similar to the original, shouldn't be too difficult, just some more cutting/drilling/welding. Hey kgg, don't you ever sleep?

Members dikman Posted Tuesday at 10:36 PM Author Members Report Posted Tuesday at 10:36 PM (edited) Yep, I don't need another one but over the years I've realised I'm happiest when I'm making something. I forgot to mention that another improvement is the knob on the left, it's so I can clamp the lefthand tool to stop it moving around.

Members dikman Posted 6 hours ago Author Members Report Posted 6 hours ago (edited) Finally finished it, made a new handle/pivot, took me two goes to get the right length linkage but the beauty of this design is it's pretty easy to modify. It is much better to use with the handle like this. And please ignore the crappy welds, there's nothing wrong with the MIG, just the operator!
