How to cut sorbothane?

If it does work you could make them in the shape of gingerbread men !

I wonder if gingerbread men would sound better than X-mas trees?

Sharp edge of a tin can? Seems also there is a leather working tool that cuts circles. Is Tandy leathercraft still in business?

I would try a roller cutter. M wife has one for cutting material and it cuts about anything I need it to. I think it will cut cleanly because it rolls instead of drags across the surface

First, I doubt that what you purchased is exactly the same material as Herbie's Big Fat Black Dots. I have them and they are somewhat stiffer than most sorbothane I've felt.

However, being a DYI tweaker myself I'd suggest you find a supplier of leather-working tools like Tandy. They carry hole punches for belts and leather projects and may well carry larger diameter hole cutters.

I just did a search and although most of their punches are small diameter you could use a strap end punch to cut half of the circle at a time. Here's a link:

If you decide to go back to 1 5/16" circles, you can probably find an "arch" punch at that dia. or something close. McMaster Carr or MSC Industrial Supply would have them. It is just a heavy duty version of the pipe and already sharpened for use with a heavy hammer. You can also have a rule die made (sharpened steel blade set in a wood base), but that would be better if you have access to a small arbor press. You can also cut the sheet on a laser. If you have a sign making or trophy making shop around they could very well have a low power etching laser that would work.

And when you decide that is all too expensive and too industrial - tin cutting shears. Lots of leaverage to cut through the polymer. MSC or McMaster or local industrial supply. The HD or Lowes versions wouldn't be as sturdy.
