Tooling to make disks?
I need a couple of hundred chipboard disks in 3.25" and 4.25" diameters. They need to be .1"-.2" thick, but the thickness is not critical as I can glue up thinner ones to get the thickness I need. I would gladly purchase them if I could find a suppler.
I make smaller diameters by using arch punches. I have made up to 2" punches out of drill rod, which work fine, but I donÂt think that approach will scale up to 4.25". I would appreciate any suggestions on how to make tooling to make these disks.
I have a basic machine shop; lathe, tool post grinder, mill, drill press, arbor press, welders, torches, pneumatic press, etc.. I have no aversion to buying more tools, but I would like to limit the expense as much as possible.
Thank you for your help.
