Trying to figure out how to mount wheels on a D-bit grinder. The shaft is straight, not tapered.
First, is this a real problem? The included cheap-o diamond wheel has radial slop on the arbor of +/- 0.002. The spindle itself, even with the belt on and turning it by hand, has TIR of a few tenths. And when I lean on the spindle, it flexes about 5 tenths.
What's a fix? Should I purchase a new grinder from Shars?
Maybe I could make straight adapters but mark the hub and arbor. If I lap the hubs to a close fit and mount them with the same clocking each time, wouldn't that solve my problem?
