Default Re: rear sprockey alignment

This is how I do it but it's only for people with access to a lathe or mill.
First I confirmed that the hole was exactly centered in the sprocket. It was right on so I took a measurement of the inside diameter of the hole and the outside diameter of my hub. There was a little over an 1/8th of an inch, (.149 to be exact). Using the lathe I made a spacer that slipped over the hub and inside the sprocket. It was then just a simple matter of cross tightening the nine bolts and when they were tight the sprocket is perfectly centered on the hub and no wobble. This will only work if your hub is small enough or you machine the sprocket hole out enough to have room for a spacer. Any machine shop could do this for you but machine shops aren't cheap.
It might be overkill but there is no way the sprocket can shift even if the bolts loosen a little over time. Just my three cents worth.
