If ya don't already know, learn about "grease cookies" in "Loading the Black Powder Rifle Cartridge" by Paul A. Matthews. Makes all the difference! Kindest Regards, Doak

If I were gonna deepen the chambers of a NMA, I'd go in w/a ball end mill of smaller than chamber OD, down to the face of the nipple. Cylinder locking slots are deep, & going past them, internally, at chamber ID, I think, is bad mojo. Hence, the smaller OD ball end mill. Keep the webb between...

Uberti barrel into a Pietta frame: Uberti barrel in front of the cylinder is ~ 1/16" (.062") too short. Yup, it is pretty close, maddenly so.

OK. Here we go...If the question is "are the barrels interchangeable, as in identical?" The answer is no. If the question is "are the threads the same on both barresl?" the answer is yes, at least since 2014. Metric system uses "pitch" to call out what we would call "threads per inch", "tpi"...

Gotta 50/90 Shiloh from Farmingdale N.Y. It's not a long range gun. At 1 turn in 36", twist is too slow for long bullets. Should be 18" or 20". "Loading the Black Powder Rifle Cartridge" by Paul A. Matthews is the one that saved my bacon. Chapter 3 is all about "grease cookies". Cookies keep...

Patch lube, by volume: 4 parts beeswax 3 parts canola oil (or jojoba) 3 parts lanolin Melt stuff in pans floating in boiling H20. Combine ingredients while they're in liquid state. Grease cookies, by volume: for BP cartridges. 1 part beeswax 2 parts jojoba Pure linen makes best patch material...

That's exactly correct. The Henry Nock Patent Breech of 1757. Design was/is used in many applications, and has several advantages. 'Lot to talk about here. Doak

Starting on page 37 of "the RUGER OLD ARMY club" thread, primer capsules are covered ad nauseum. 209 primers are too large to fit in the ignition ports at the back of ROA cylinders. Small pistol/rifle primers are what works. Kindest regards, Doak

Underhammer long guns suffer from too shorta ram rods. When ram rod pipes are on the bottom flat, the length of the rod is limited by the nipple (or frizzen, :D). The solution derives from thinking outside the box. Place the pipes one flat over, on either side of the bottom flat, allowing the...

You're right! Tuning & easing the frizzen spring is beneficial. The frizzen will work just fine w/out the frizzen spring. The frizzen spring's only real job is to keep the frizzen closed, or keep it open, depending on the shooter's wishes. Frizzen should snap open as the flint approaches the...

Switch to pure linen. At least .010'' thick. Never look back. There are a number of reasons, if ya wanna hammer it. Kindest Regards, Doak

I've always used super-glue. Cyanoacrylate (spell?), chemically. It capillaries well, deep into cracks. Cleans up w/acetone. Sands well. Scrapes well. Stores in freezer well. Gotta work fast, cuz it goes off quickly. Apply plenty, along full length of crack, all sides. Tape, clamp, rubber-band...

When the "set trigger" slaps the "sear bar" up, the "sear" moves downward, off the full cock notch, allowing the hammer to rotate forward. There's prolly not enuff trigger travel, to hold the "sear bar" up, far enuff, while the 1/2 cock notch rotates past the sear. Instead, the "sear bar"...

Starting on page 37 of this forum, primer capsules are covered adnauseam. I'm still makin' 'em. Right now for Pietta 1858's, along w/reworkin' the revolver. Made a 1.1 GB disc of fotos & text covering the process. Disc is available, free, for anyone wanting the info. Send me a shipping...

Underhammer's suffer from short ramrods, cuz the rod, when positioned on the bottom flat, runs into the nipple. The solution is to solder the ramrod pipes onto the next flat over,either to the left or rite, of bottom. Or place 'em on both side flats & carry 2 rods.
