But..why didnt you simply make a die stamp and press em out? I tried a simple hammer punch at first and I was very unhappy with the results. Probably my available metals. I wasn't sure how to go about making a stamping plate that would work. I dunno know though. The hammer punch was made from the driveshaft of an outboard lower unit. Even an arbor press would have done the job and you would have knocked out one lable with each fast stroke? I've got a hydraulic press. Maybe if I saw a stamping plate setup in operation I could figure out how to make one, although the way I picture it in my mind I would need to make three detailed pieces to make it work. Relief plate, guide/clamp, & punch plate. All three would need to have all buttons machined. I could write the code after some experimentation now in a reasonable time to cut each piece, but it takes a lot of time, and after my hammer punch experiment I wasn't sure I wanted to spend 6+ hours machining each piece. And I am thinking atleast the punch plate would need to be hardened. This is a small project. I may never need to do any more of them after this job, but I will save the plates and the code(s) on a mem card with them. Ten years from now I'll look at the two plates and laugh about how silly I was to do it that way. |
