The bolts, bearings, plates holding them, all have some mechanical slop in there interfaces (it's all through holes, not tapped).

There is nothing wrong with adding more spacing in the plates to account for lower tolerances if you can't hold +/-.005. It will just add slop.

If too tight initially, take some time to wear it in. The steel bearings will wear the aluminum to a happy medium pretty quick.
