Wot, no replies?

I suppose it goes without saying that if you've overtightened the bolts
to the extent that you've bent the lower bearing housing you've got
problems now, not later.

The rather odd design of the bearing housings on unis invites
overtightening, which pinches the bearings into a slightly oval shape.
Since the inner bearing is constrained to be round by the shaft it's
on, the bearing will be stiff and wear out quicker, as the balls have
to squeeze through a smaller gap than they're designed for.

I don't think there's any merit, with nyloc nuts on bearing housings,
in tightening much beyond finger-tight.

No doubt Qu-ax can provide a couple of replacement bearing housings and
some bolts.

When I get around to making a uni[1], it'll all be much better designed
- properly machined bearing housings that extend the full circumference
of the bearing, less a couple of thou.
