DV8DUG Report post Posted July 10, 2018 So my needs are simple for now. I need a press to chop out smaller pieces from piles of post commercial leather waste. My pieces hardly ever exceed 6" in any direction, most being around the 2" x 4" size. What kind of tonnage am I looking at for punching through 12 oz. to 14 oz. latigo? What would be my cheapest and easiest options? I see refurbished 'clicker presses' on eBay and I'm not sure if building the whole setup from just a ram and a stand is a good route to follow or if a completed setup is. I possess the skills to put something like this together... It's just a lot of work when I should be leather working. Currently I use a double jack sledgehammer with the handle cut short and welded steel homemade dies. This can't continue... LOL Quote Share this post Link to post Share on other sites
Mark842 Report post Posted July 10, 2018 I've heard this question asked hundreds of times. Even asked it myself a gazillion years ago. Here is an interesting article on the topic: https://diecuttingengineer.blogspot.com/2010/02/calculating-die-cutting-tonnage.html?m=1 The funny thing is every formula supplied on this article comes up with a different answer for required tonnage. Of note also is that the formulas tell me that I would need a 60 ton press for my most involved die even though I cut with it daily using either a 25 ton press or a 15 ton. Both presses cut it exactly the same, very easily. My most involved die is about 27 inches long and has about 350" of linear blade (Its a 12 strand fringe cutter). For the dies you are describing a 15 ton would probably still be over kill. Quote Share this post Link to post Share on other sites
Northmount Report post Posted July 10, 2018 I have been cutting 6" circles with a 1 ton arbor press. It is clamped to the bench, and added a piece of 3/4" pipe to the handle for the harder, thicker leathers. So I would say you should be able to do well for your pieces with a 3 ton arbor press. Then you shouldn't need to add the snipe for more leverage. Tom Quote Share this post Link to post Share on other sites
Matt S Report post Posted July 10, 2018 I make do with a no-name Chinese 6 ton hydraulic press for similar size dies. Cost me all of £60, plus the steel plates and a kitchen cutting board. Quote Share this post Link to post Share on other sites
