gunnut69,
I'm not looking for a cleaning rod. My intent is to end up with a ramrod that fits the shotgun's thimbles. I'll turn a tulip shaped cap for one end, but I want the other end able to accept standard black powder cleaning jags and worms for use in the field. The current rod is a pretty, 6.9mm diameter, wooden rod that is too flimsy for continued used, which has only the tulip shaped cap for seating wads and no provision for jags or worms.
If I had a lathe, I would simply buy the stock, drill and tap it, and cut to length. I believe that I can buy a cleaning rod and cut it off cheaper than I can have stock drilled and tapped by a machinist.
