Muzzleloader question? SORRY it is called a drum!

[Ace Lungger]

Howdy Pards,
I have a 1987 CVA musket, and the nipple treads are bad, and since I know nothing about muzzle loaders, i saw on one of supply stores on line that you can buy the barrel bolt, this one seems to be in there pretty good, what would help me a lot is to know is are they rh. or lh treads? I assume they are light all gun screws, but before I put a small pipe wrech on the barrel bolt I could use all the advice I can get!! I am sure i can retap it to a bigger coarser thread, but that isn't the proper way to fix it!
I should of look it up and called it by it's proper name. it is call a drum.
Please help!

Thanks
ACE

CVA used to use a different drum than the normal muzzleloader.  It went through the breech area to the other side of the barrel, then they would drill the hole in it for getting the flame from the cap into the main load.  Hope this helps.

 Ace , I have never seen one that had a left hand thread. IN twenty years of working on muzzleloaders they have all been right hand.  Good luck with it.  GB

Howdy fellows,
Here is what I did, I bought a 4/28 nipple, I bought a 4-28 bolt and 3 nuts. I put my barrel inthe mill vise and mill a new hole in the drum. I then put the 3 nuts on the bolt and tighten them, took my good calipers and miced the milled hole, turned down the first nut to 1000's over size of the milled whole. Froze the nut for 24 hours and then I took a pencil tip propane torch and heated the drum, with a plate that I drill a hole in the plate and put it over the drum up against the barrel and with water soaked rags, never getting the any heat to the barrel, and did not get the drum anywhere near red hot and then I had a friend bring me the turned down nut tapped it in with a brass driver. After making 6 notches around the the outer edge of the newly mill drum, I spot tig it in a manner as you would tork a wheel, so no pulling or warping, after that i spot mig the rest, ground it down to make sure there wern't any pin holes, then i flux it and solider around it. Then I put my new nipple in and bingo!
I feel if the nipple is removed each time the rifle is shot, clean the nipple and theads and then lube and re install I don't think  there could ever be a problem.
What do you think?
