I was just hoping I could get more mileage out of this, for the hell of it really, no real good reason. It does seem round though it is only measuring too small.

Other question, for your expert judgement: with the flywheel on, if you can move the crank in and out (not up and down, but in and out) does this mean the bearings are shot? Seems to move quite a lot, difficult to tell just by eyeballing it but it's quite a bit.
