As the build progressed, I realized that the ramrod is 5/16" diameter and not the 3/8" diameter I was told when I ordered out this fowler. Worse yet, it requires tapering down to LESS than 1/4" in order to fit into the stock. And even more weird is that the forward pipe allows a 5/16" rod but the middle pipe needs the rod tapered down to about 9/32" to fit in, and then further tapered down to 1/4" in order to access both the rear pipe and the stock.
Not happy over the rod situation because I like to use my ramrods up outta the pipes and straight down into the tube, back up outta the tube and straight back down into the pipes - none of this silly rod twirling. I tenon the outer end of the rod (that's at the muzzle) with a brass ferrule that will allow a jag/worm/scraper and the business end that lives inside the stock is left pure wood that I wick in some water thin CYA to its end in order to harden.
I'll ring up Jim about the rod but I expect its dimensions are "period correct".
Finishing might be compete by next week.
