1949 Rear Brake Drum
« on: 30 March, 2017, 21:39:57 »
I am restoring a 1949 B31 and have looked at the rear sprocket and decided that it is not good enough, can any body tell me where to buy a new one or do I have to machine off the old teeth and weld on new.
The rear drum is not currently attached to the hub, I am assuming from what I have read is that they were riveted on, can you just use bolts or do I have to make rivets?.

Thanks for any advice.

Presume its a rigid not plunger?

If rigid I think you will find it hard to find a new one but there are engineers who will retooth for you - one currently advertises in Old Bike Mart - John Hemming Engineering 01547 530759 - I have not used him. Those drums are thin so you need the braking surface to be good I dont think there is enough metal to skim.
