Thanks Mike.

How about the joint depth? I understand that it would be part of the initial reaming, with the hole diameter for the breech section being sized to fit the outside tube diameter. Or, do the new tubes need to be milled on the joint flange?

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
