Stamping / punch press of unknown maker and die making?

This machine is equipped with a 0.46hp electric motor and features a flywheel measuring 10-1/2" x 2-1/4". After examining similar motors and flywheel specifications found in other presses, it seems reasonable to estimate that this is a 3-4 ton press. The press has a stroke measuring between 1 and 2 inches. It operates at a relatively high speed; therefore, precise measurements are not feasible (I certainly won’t be putting my hand in there with a ruler!). The overall weight is substantial for its size, likely around 120-150 pounds. It contains various zerk fittings, but I lack documentation for the appropriate grease to use. After plugging it in, I confirmed that it runs smoothly with no apparent issues.

My intention is to use this machine for shaping small, thin pieces of brass or aluminum using dies that I plan to create. If anyone has experience with stamping die creation or can recommend a solid tutorial, I would greatly appreciate it. I grasp the basic concept of constructing dies with opposite shapes (male/female), but I am unsure about the recommended clearances for the material. Furthermore, it isn’t clear whether the piston should fully bottom out, slightly bottom out, or if the die should prevent the piston from achieving full travel.

I came across a chart indicating that a 3-ton press is capable of punching 1" disks out of 20-gauge steel, so I believe this press should adequately handle stamping thin brass at 20 gauge or even thinner. Given that the press was free of charge, I can’t complain about the cost.

Having found a place in my workshop for this benchtop electric press, I desire to gather more information about it. The only identifiable markings are “Red & Gold Technical Services Inc,” which seems to refer to the previous company that operated the machine rather than its manufacturer. Numerous internal components are from Japanese brands, hinting that it may have been manufactured in Japan. Regardless, Red & Gold is no longer in operation. I’ve spent time searching on Google to identify a similar press, but I haven’t located anything closely related that could point to a specific manufacturer.
