Rolls damaged upon rewind by an Ampico A:  You may find that your
right-side rewind spindle is knurled, thus you can use your finger
to drag the rate down or even stop the rewind.  You may find that the
roll's left flange is loose in its cardboard tube or pushed too far to
the right.  If loose, it can slide to the right under the force of the
spindle spring.

You can set the available space for the roll by shimming around the
flange, either making its tube larger or limiting how far it can be
moved to the right.  'Gingerly' and 'thoughtfully' are the words here;
the paper changes in width with seasonal humidity.  You may find that
the roll's tube is quite a bit shorter than the width of the roll
itself.

Many of my rolls play and rewind with nary a waver in lateral position.
Some do waver and a little effort to cause the roll to lay to the right
will help.  Some rolls are damaged or repaired and so tend to steer
away from the implied (by fraying or folds) or actual extra thickness.
Such rolls are less amenable to 'thwocking' them to the right.  I have
yet to break a flange, though warned, by dropping a loosely-wound roll
squarely on its right side drive flange end from just a few inches
above the floor.

A really wavery roll, or one that was not sufficiently amenable to
'thwocking', can be steered to the right during rewind by controlling
the rewind rate with your right hand and loosening the roll away from
the tracker bar with a delicate finger of the left hand.  Once the roll
is neatly stacked to the right, it will tend to play and rewind with a
better attitude.
