You know, I was thinking about this while walking home for lunch today and I thought that if I only could find some shim material to go around the hub. lol
I think I may have to hone out the sprocket a bit more too. Honed it out to good fit on the original hub but that was black anodized and I have a feeling that even though this hub is by the same manufacturer the chrome is adding a few thousandths that is giving me trouble. The sprocket does fit over the hub but it's a frog's hair off from being a press fit. A few more minutes work with the emery cloth modified brake cylinder hone may just do the trick too.
