Stamping / punch press of unknown maker and die making?

It has a 0.46hp electric motor with a 10-1/2" x 2-1/4" flywheel. Based on looking at the motor and flywheel specs on other presses I'm guessing it is a 3-4 ton press. It has a stroke of somewhere between 1 and 2" inches. It goes pretty fast so just a guess, I'm not sticking my hand in there with a ruler ). Very heavy for the size, guessing at least 120-150lbs. It has a number of zerk fittings, but I have no documentation to suggest a proper grease to use. I plugged it in and it works with no obvious issues.


My hope is to use it to shape small, thin brass or aluminum pieces with dies that I make. If anybody has experience making stamping dies or knows of a good tutorial i'd be very interested. I understand the idea, of making the die to opposite shapes (male / female), but really no idea of recommended clearances for the sheet, or whether the piston should perfectly bottom out, not quite bottom out, or if the die should stop the piston short of full travel.

I found a chart that shows a 3 ton press should be able to punch 1" disks from 20 gauge steel, so I'm thinking this should be more than adequate for stamp thin brass 20 gauge or thinner. It was free, so I can't complain about the price.

I've given this benchtop electric press a home. I can't find much info on it, the only markings are Red & Gold Technical Services Inc which I believe is the business that used it, not the manufacturer. Several parts inside are Japanese brands, so possibly made in Japan? Red & Gold is out of business either way. I've spent some time searching Google, and can find similar presses, but nothing close enough to suggest a manufacturer.It has a 0.46hp electric motor with a 10-1/2" x 2-1/4" flywheel.
