My Jet drum sander drive roller decided to snap on me so here is the fix I undertook to get it back up and running.
The cause of failure for this could have been metal fatigue as the roller is under pressure from the conveyor belt. What did not help the fact is that a 'cheaper' aftermarket conveyor belt I installed was horrible to get to track straight. One end (motor end) had to be very taught while the other end remained supper loose just for it to track straight.
So as well as fixing the roller I also bought a more expensive conveyor which now tracks a lot better.
Broken shaft on roller:
Cutting new longer shaft. The idea is to drill the roller and then insert a new shaft from what i believe to be tool/silver steel.
Turning the ends.
Roller now in the lathe for drilling and reaming.
Shaft in place.
I will be using grub screws to hold it in place so filing some flats.
