Thanks - nice explanation. (Your writing background coming to the
benefit of RCM'ers once again G.)

The background for my question as this: I had made slip rolls and
fastened the handle to the roll with a taper pin. My reasoning was that
I could get a better fit than _I_ could with a straight pin & avoid
wallowing out from a loose fit. But a split/spring/roll pin would have
been so much easier. Not nearly as good, I see now.

Thanks to all,
Bob
