Scale Model Clutch Pulley

that looks like the same type of clutch in my old case garden tractors!

the pulley with the friction material gets pressed onto the engine pto shaft.
its simple and works

I think Bob is right. I would try metal to metal first. Unless you are going into production sawing. After all this is a low speed, low power application. If that isn't satisfactory, I think I would go with wood over rubber. I think wood would engage easier and I prefer the smell of burning wood to burning rubber.

By the way, are you a golfer? Any golfer would be happy it he could two putt every hole!

The old Gravely two wheel garden tractor with a planetary transmission used four cone clutches. Two were for high/low speed and two were for forward reverse. It used a dog clutch for the front mounted PTO.
