 Tom- To me it sounds as though you generated a bit of a burr, either on the cam or the shaft.
If you can identify the high spot, it might be easier to file off the spot causing the fit problem,
rather than to continue using the emory cloth. A trick that I've used to find high spots like that
is to coat the shaft with a ink pen, and then fit the parts. The high spots scratch away the ink.
