Here are my latest mistakes and how I am correcting them. Top rifle is a .50 B 38" Rice barrel with a Chambers Late Ketland flintlock in a Stonewall Creek Outfitters stock that I am finishing up. I put a coat of stain and finish on it so I could shoot it in our Easter Peep Shoot so the big boys wouldn't kick sand in my face for shooting a caplock. It needs more shaping and sanding.
Bottom is the same barrel in a blank. I traced the upper stock on it, but rotated it at the lock bolt to drop the heel by 1/2". This lowered the muzzle by 1 1/4" for a better fit. I sawed out the pattern, routed the barrel channel to the minimum barrel width. Hand inletted the swamps at the ends and bent and inletted the tang. Routed the ramrod groove and drilled the hole, 3/8". Installed the powder drum and inletted a Siler caplock. Located the lockbolt hole on the bolster, drilled it and then drilled through the wood and tang.
Now here is my mistake. Using the same sideplae as the upper rifle, I drilled it for the lock bolt. Placed it and drilled for a front lock bolt (making it as a conversion from flint to percussion). I wanted the lockplate to curve into the wrist, and inletted it.
Then I discovered my web was too thick when, after installing the rod pipes (I cut the tabs .1" above the pipes) the ramrod had about a 1/4" gap below the nosecap. So I inletted the pipes deeper, to match the above rifle. Used a 3/8" round scraper made from a screwdriver, and a 3/8" rattail file with tang bent at right angles for a handle, I cut the ramrod groove to match. Drilled the hole to 7/16" for about 4" and scraped the step out with a steel rod. Now the rod is close to the nosecap and slides smoothly into the stock.
I also inletted the entry pipe deeper to match the above stock. The tail sets the line for the lower forestock back to the trigger. I marked the trigger plate stock depth the same as the above rifle and rasped to this line (using a rounded Surform rasp that cuts well). Set the buttplate on to length (13 1/2" LOP) and drew a line from the toe forward to the trigger area. Drew a radius here. Cold-bent the trigger plate to this radius.
Now I found my sideplate was too low. I had cut the panel thinner than the lock side (bolster thickness), so could not rasp it off and re-inlet. So I sawed a filet out of the comb line, matched the grain, drew the sideplate pattern on it, sawed and filed it out, inletted it, stained the glue, clamped it in and filed it out. Now I will re-inlet the sideplate higher (to the pencil line), cutting off the top of the hump and reshaping the sideplate a bit. Filled the hole with brass soldered in. New hole will be drilled lower.
I don't know why that lock bolt came lower than on the flintlock, but that set the sideplate lower. I have before installed the lockbolts, then drew a sideplate pattern to match them and sawed it from brass. Sideplate fit can be tricky.
I got lots more mistakes I have made, but enough for today!
