Another question: what to use for pins to pin the barrel to the stock? I thought that brass was traditional, in which case I need to find some brazing rod. Howsomever, I do have some steel rods about 1/16" diameter which could be used. I just wonder about it being susceptible to rust. The H&A underhammer, my first ML rifle which I foolishly sold, had the forearm pinned on with brass. Which would be better, steel or brass?
In the meantime, I have the butt almost completely matching the butt plate; just a few more passes with the rasp should do it. Then I will file the edges of the plate to match the wood and the wood to match the plate and I'm done there.
The barrel has two dovetails in the bottom flat. One was for the wedge lug, the other for the nut to which the under rib was screwed. I'm planning to use them for the underlugs. However, the one for the wedge is way long, almost 3/4" and the other is shorter than a standard 3/8" as they are both metric. I am making underlugs to fit from some pieces of steel I picked up at the hardware store. I only have 0.233" of wood between the barrel channel and the ramrod channel so not enough to even think about using wedges to hold it together.
All in all it's another learning experience!
