To ream or not to ream

[Roger Jolly]

Hi Dave,
             I hand ream with a drill bit, and a large size tap wrench that
I tighten in the vice to prevent slippage of the bit. It's a slow way to do
it, but I have recieved the best results with this method,very consistent,
and less jumpy pins. Purchase high quality bits from a machine supply
house, explain that you need nice sharp flutes. The better supply companies
will have a tool pro on staff that will help in your selection.
I would hardly call your question rambling, it's very pertinent.
Regards Roger
