Greg,

The tedious hand reaming, if done properly, assures a consistent fit from
center to center, while a reamer,  spinning at over 30,000 rpm, would be
difficult to control and could lead to some great variations in the fit of
the centers, due to the heat build-up and friction of the spinning pin.

Sometimes the best results simply take a little extra time to achieve. In
an area as critical to proper action performance as pinning, I would take
my time to insure the best results.

Good luck.
