Sorry, no. OR he's confused about what it means to have the flanges
tightened down properly.

The flanges register to the shoulder on the arbor. If the stone's hole
were cut so 'diagonally' that it couldn't seat on the flanges, then
tightening them down until they seated flush to the wheel surfaces would
break the wheel.

The radial run-out is probably the wheel. So what? That's what wheel-
dressers are for.

Another potential problem is the SAE shaft and metric wheel
difference. Tape up the shaft to true the oversized center hole of
the wheel, then dress the mounted wheel to round/concentric.

Even HF wheels don't mount tightly to HF shafts, and both are
semi-metrical objets d' art. Amazing! g
