Hi Richard,  The most common cause of a cylinder not moving on its axle
is that the 'pitch' inside the cylinder has sagged and is dragging on
the axle.  There is only _one_ way to fix the problem... but -- a most
sincere warning -- you can create more problems by doing it wrong in
trying to fix it.

When cylinder boxes were made the cylinder was pinned and, before the
second end cap was put on, the cylinder was filled about 2/3 full with
molten or liquid 'pitch'.  The cylinder was then spun in a lathe and
the centrifugal force created threw the pitch to the inside wall of
the cylinder, thus creating a 'hole' for the axle to pass through.
In order to correct sagging pitch you have to 're-spin' the cylinder.

_Be aware_ that you can totally destroy the cylinder by overheating it.
You can split the seam along the length of the cylinder; you can
distort the end caps.

I do not encourage anyone with no training to try it.  But if you're
hell bent on doing it (and you can't fix the problem without actually
doing it!) you can give me a call and I'll explain the process to you.
It's easier to talk to you and answer immediate questions than it is
type out the whole process.
