(make sense?)

the collar is already on both sides. the collar it'self is 1,1/2" long with the sprocket holder centered. the problem is the hub is being beat back and forth because it is a slip fit. thats why I think a split lock hub would work better to close up the tolorances. It could be tightened to clamp on the axle.
I use the conduit stop concept but I use thick wall scd.40 pvc pipe with 1' ID for the spacers. cheap ,light, water proof, saves the axle from nicks and it serves as a good rub surface. With the right saw blade you can slice the stuff paper thin for shims
