I now have the trigger and guard and butt plate inletted and am slimming the wood to shape. My guard is Track's TG-MA-92-S and the trigger is TR-York-TP. I riveted the rear end of the trigger plate to the guard (this is a temporary rivet, a small brad) and soldered a 5/16" extension on the front to move the trigger back in the guard for more gloved finger room. (Monica will be hunting deer with this .50 in Michigan). I notch the front guard lug to hold the plate in place. Then I cut the lug off to clear the ramrod. This way the ramrod can go back to the tang bolt, another 1 1/4", that much longer than the bore without sticking out in front of the muzzle. The tang bolt holds the whole assembly in, but I also pin the rear guard tang into the wood.
Closeup of the notch. The case has a wick and kerosene in it, a soot lamp for blacking parts for inletting.
Now that the trigger is in, the length of pull is established by fitting the butt plate. I mark the outline of the BP on the wood and saw it with a 14 TPI blade hacksaw.
The black high spots are pared down with a screwdriver-scraper, seen at top.
Any gaps at the edges are hammered down with a ball peen hammer. The toe was away, so I put it in a vise and carefully bent it flat. I set the plate to the side for cast off.
To remove excess wood, I use a 3/4 inch curved gouge and mallet, followed up by a Surform rasp, then a cabinet rasp and double cut file.
