Screwed up.

Would it be ok safety wise to plug where a drum is screwed in to the varrel. Then dress the weld up and Redhill and installer smaller threaded drum? It has a 3/8 x24 now.
This is a 32 caliber and will never be loaded with more than30 gr 3f and most likely 20 to 25 gr.

I'm pretty sure I've seen posts of thos being done before.
Hopefully one of our better builders will be along soon with a more concrete answer..... Maybe after their holiday festivities are over?

I think a lot depends on how and what you use to weld it up with - i.e., O/A, Mig, Tig and how good you are at it. If it was me I would cut off the back of the barrel then rethread it and set the barrel back giving you a shorter barrel. Just my 2 cents worth.

If the existing threads are OK why not just turn down the drum?

Or cut off the drum and drill for the smaller size.

There are a lot of variables involved here.

If done correctly, red loc-tite would be sufficient to secure those threads.

Once cured you can drill and tap and snug down the new drum without fear of it busting loose.

Red loc-tite is a rock solid repair and a muzzleloader will never generate enough heat to soften it.

I will get abuse for this, but after I have the drum all positioned, I take it out and coat barrel threads with a very little JB Weld and screw drum back in and wipe off excess. Run pipe cleaner thru cleanout hole to be sure ignition channel is clear. Replace lock to check position. I never anticipate removing drum, but if I had to, heat from a gas stove flame for a minute will make the epoxy turn loose.

Why replace the drum at all? Bigger threads make it possible to make a bigger flame channel. IT is also stronger. What is the reason for wanting smaller threads?

 

[Crow#21957]

Jb the drum that my kinda thing.

And 45/70 I'm keeping the bigger threaded drum. I'm just trying to solve a drum that looks and is slightly crooked. Hade to heat and bend the hammer more than I wanted.
I'm pretty sure I have the solution. Just waiting on new drum and other stuff. I will post later on this 4 to 5 days due to mail.

I had already drill 1/4 hole which was a dumb mistake. I really don't know what was in my head. Was trying to get a nipple to fit or next size bigger and re drill and tap. Ended up I had a 3/8 x24 so I used it. Got it a little off square and I'm working on a solution. I believe I've got it. Will send pics when done.

No welding on barrels ever. the heat will weaken the metal

I agree
