Set the height of the bolts so that top plate hits the bolts just after the leather is cut. If your dies are the same height (mine are) then you don't need to change height. IF you also use the press for wet forming and thus need a different height on occasion, then add a jamb nut to teh bolt(s) so you can remove teh bolt, do the forming, and put the bolt back in the same position easily. Expand I'm seriously liking your work here as I appreciate those who "think outside the box" and who will stay at something till they solve the issue . . much genuine respect from one who comes from an engineering family.

How do "they" - or rather you - know when to stop? My reason is that I can use my welding and engineering skills to make similar to the above to suit our leather needs . . whereas here in the UK a reconditioned second hand machine costs about GB£3000 up to between GB£5000 to GB£7000 for a new machine. So, a truly cost effective exercise then. Expand Here is a picture of the bed with the positive stop bolts on each side of the bottom plate. Quote

Members Brianm77 Posted March 31, 2017 Members Report Posted March 31, 2017 So, I have been thinking about turning a press into a clicker. My question is, any reason you should dedicate your press to being a clicker, over just setting some plates on top of your die and getting after it? Quote

Members Brianm77 Posted March 31, 2017 Members Report Posted March 31, 2017 So the plate welded on the bottom of the jack is only to speed up the process? Quote
Members Hooper26 Posted March 31, 2017 Members Report Posted March 31, 2017 This is just the type of question I wanted to ask. Using a shop-press for clicking out leather. The 20 ton press is very cool. Has anyone ever used a little one ton arbor press, from Harbor Freight, to click out small pieces? I was hoping to get a small, inexpensive press, that I could have a die made for, to click out firefighter helmet shields with. With a few modifications I could start clicking out my pieces for way less than paying for an expensive clicker from Weaver or Tippmann. Has anyone ever tried this? Thanks. Quote

On 8 oz. and up, takes 4 presses, 1 at each quadrant. Didn't use a full size piece of steel plate over the top, so maybe could have done it with one press in the center, but would be a heavy pull. Still faster than cutting by hand, and more accurate. Smaller items are of course easier. Tom Quote
Members Brianm77 Posted April 1, 2017 Members Report Posted April 1, 2017 I tried my .5 ton on about 1.5" circle and didn't even come close. Did not have a very sharp die though. I have been contemplating making about a 20 to benchtop model with a jack. Quote
