I believe that type of material, production rate and quality of the mold pockets plays a great part in the quality of the wheels and with the B.S.A. wheels there is a large variance. We have found that there are a couple of mold pocket numbers that provide a excellent wheel and there are several that produce a consistant piece of junk.terryep wrote:Re: hole placement in the hub. These wheels are injection molded. Molds are made to fine tolerances because there parts have to fit closely.
I know that there are a few mold numbers in the B.S.A. wheels that Randy at Max V will not even sell, they are that bad every time.
As far as mandrels go, I have found that you need square shoulder to index from and provide your driving force, a centering cone of some type to provide parallelism from the hub and a screw of some type to provide a bit of clamping force. You don,t want to slip.
