40 mm wad punch
 

I'm trying to get hold of a 40mm wad punch for making rubber discs. 38mm
would do at a pinch.

Anyone have any idea of a source of supply? Can't find them in any of my
usual sources.

how thick is the rubber?

Them cake doe cutters are ideal for cutting discs in rubber. Local
chandlers.
