Reamer Made to Correct a Large Bore....Reaming successfully completed
davec2:
The original plan was to have a pilot in front of the reamer. However, the bore for the fist 20 or so inches is line to line with the 2.750" shell reamer. As a consequence, the reamer will go that far down the bore without needing a forward pilot. But it does need the guide I am machining for the muzzle that will support the reamer shaft as I work the reamer down through the last portion of the bore. I have toyed with the idea of opening the bore to a full 3 inches in a similar manner. In that case I would need the forward end pilot to start.
However, in a moment of sanity, I realized that there is no true "need" for the gun to have a 3 inch bore vs a 2.75" bore.....and if I did take it out to 3 inches, it would cost even more per round for powder and shot (and it's fairly expensive as is. Even a light load is 1/3 pound of powder and about $12 worth of cannon ball) !!!!

Oh yes. How cool is it that you just back that baby up to the “shooting range” and light her off?!

That reamer HAD to cost some serious bucks.

Wow! The quest for accuracy in round balls, regardless of size, is a passion. Have you considered some micro rifling? Or a rifled sleeve?
Nice work on the reamer. The handle may be too short for that pitch,
I have every confidence you will get it done.
Daryl:
What about a delrin or teflon muzzle guide?
Brass would also work, I guess.
