I have been doing a bit of reading, and of course looking for some pieces of
O-1 since my thoughts on punching out aluminum. One of the things I've
noticed is the stuff seems to be hard to find on-line. There are several
vendors selling small pieces on Ebay, but its all pretty thin or not wide
enough to do the job. I am curious if pieces as thin as .250 or .375 can be
used for the type of operation I described. The only thing I have to
compare to is the hydraulic slug buster I use on electrical boxes. It's a
heck of a lot beefier than that even for the smallest KO dies.
