Slicing a hockey puck into discs (vulcanized rubber) Answered

I need to slice a hockey puck (1” thick by 3” diameter) into very thin discs (1/16” to 1/32” thick). This can be done... the NHL sells 1/4” puck coasters (see photo). Thinking about a mandolin design where the puck is mounted and the blade moves with my hand in a sled device. Puck rubber is very hard to slice. Thinking of Japanese angled blades (‘7’ shape rather than the American ‘V’ shape). Looked into ice auger blades (for blade thickness and stability). Just about de-gloved my hand with large box-cutter blades (bent as well when cutting the rubber). Any ideas? Raincock@ualberta.ca

AFAIK a wire would work.
Something thin and durable like dental or thin piano wire.
The speed from the movement heats the ruber and transports the debris out.
There are special wires available for windscreens but they are quite thick and not really designed for a clean cut.

You can also use a heated wire similar to cutting polystyrene but the fumes produced will be harmful and proper ventilation or a breathing apparatus is required.
Cleaning the cut only leaves sanding and solvents, for the later I have too little experience with rubber to make meaningful suggestions.
