I just put up a webpage doing a comparison of the 305 and 450 drums with side by side photos of a few examples out of my brake collection.
Just curious as I search for my front end setup. Seems like it's hard to come by the cb450 drums but there's alot of 305's out there. I dont have any data infront of me but not sure if all 305's superhawk, dream, scrambler cl77's have identical drums for my cb350?
Better yet, anyone getting rid of a hub or complete wheel that can be adapted to my cb350 for sale. If so holler at your boy.
I hope you have a good understanding of engineering, metalurgy, and finance. I am pretty sure the billet chunk alone will cost close to $600. IIRC, most drum housings are cast to keep the price down. Drum brakes are subject to stresses that far exceed disc hubs. The intallation of metal liners alone will probably set you back a good chunk and you still have to figure out which drum setup you will use. There are so many drum brake bikes out there from which to steal you are probably better figuring out a way of converting big rear discs off larger bikes than you are making your own drum out of cnc.quote:
Pretty nice aren't they. I look at them sometimes and rub one off.
But...hey whose got $1600 lying around.
I'm trying to come up with a design that could be machined from solid stock and bolted together....something cheap like $600. Frank C. ought to help us out and do one up CNC for us.
