I am starting another try with parts from TRS for a .62 Rifle, which incorporates parts from various model Brown Bess muskets, and a rifled 36" round barrel, for what they called a “British Officers Fusil”. (My friend refers to it as a Rifled Musketoon).
My first try was using a stock of very brittle Black Walnut that I wasn’t able to work with, and after too many problems I ended that fiasco.
I started anew with piece of clear Maple to use (more budget-friendly); Although I would prefer Walnut, I'm not going down that path again, buying Walnut sight-unseen.
So far, I have the barrel bedded in and the lock installed and bolts done.
The top of the lock mainspring just barely touches the side of the barrel- I had to file a small bit off the barrel to get it to fit. Then I needed to file a small divot to allow the forward lock bolt to pass under the barrel, about 1/16". I haven't run into this kind of problem before. I wonder if this lock was correct for this size barrel, or if I am just screwing up. Probably the latter.
Anyway, I am hoping things go smoother. I kind of see this more as a learning experience than anything else.
