It's a run what you brung kinda project. Took 6.5 hours to mill the top
plate. Only took about 2 to make the bottom plate. It takes 28 minutes per
run to cut ten sheets plus a sacrificial one. I jacked up the speed and cut
them at about 17 minutes, but the quality went to heck.

Obvious a vinyl plotter would have been better and just feed it some velum,
but this works and provides a really professional result.

... and I have this machine. LOL.




Cool!

But..why didnt you simply make a die stamp and press em out?

Even an arbor press would have done the job and you would have knocked
out one lable with each fast stroke?

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.

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.
