Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

Muzzleloader Repairs

#1 Post by shoggoth80 » Tue Jun 27, 2017 10:38 pm

Ok. So I saw these coming.
I have a cheap little Markwell Kentucky rifle I got from a friend. The nipple threads are shot. It was 6x1. I could either go oversize, or sleeve it. I'm not positive what sleeving entails, but if it's anything like helicoil on a cylinder head, I think I could pull it off. Anyone with experience here?

I need to un breach the barrel. It has a hex breech plug with integrated tang. There's some gas cutting, and I want to clean, and either grease, or Teflon wrap the threads. Seen references to both. I'm guessing mark the area where the threads fully release so I can properly reindex the plug?

Other than that, I'm seriously thinking about cutting it down, and recrowning...similar to the old hunting rifles of Stutz. I know it won't be a long range piece... But it would be fun. Seen videos on how to do this, it doesn't seem too horrid.

I could pay a smith for it. But I'd quickly eclipse the cost and general value of the rifle... Making a lot of the labor intricing to do myself.

Thoughts?

Ok. So if anyone is watching, I unbreeched the rifle, scrubbed the crap out of the bore. Far from perfect, but I know it still shoots ok. Cleaned up the breech plug, wrapped the threads with Teflon (as I had seen recommended several places elsewhere). Tapped the drum for a 1/4×28 nipple. I tried putting in a musket nipple... Too tall. Installed a #11 T/C nipple... And huzzah! Threads in nice and tight. Wrapped the threads with Teflon as well for general protection.

While I was at it, I stripped, and stained the stock a darker color. Needs more oil, but it's looking alright. My buddy took it to two "gunsmiths" before he gave it to me. Dunno what their damage was for not being able to fix things. Wasn't that hard... Not an overly complex machine or operation. Gotta replace, or drift and stake the front sight as it wiggles a little. Get some ramrod thimbles, and cut a rod for it, and it'll be my shameless little shooter.

Looks great and good going!

TIP - Front Sight, a neat trick is to remove it and using a center punch or prick punch, stipple a few punch marks into the base of the dovetail. Will be invisible once installed.

With the muzzle away from you, sights and pins are always inserted from right to left and removed from left to right. And while I'm at it, a center punch has a 90-degree included angle on the tip, whilst the prick punch has a 60-degree angle. You might know these tips, but others reading this may not.

Again, good job! I just saw this post - missed your original post from June - otherwise (as a muzzleloader) I would have offered to fix it for you. Cheers!

Cleaned up and tested. It shoots. Holds the pressures.
The sights still need work, but it's still better than it was. I'll get it dialed in soon.
