TC breach ?

[dennis waggoner]

'the object" isnt stuck in my gun but I have seen and heard of some interesting bore obstructions. bullets stuck in bore with a couple broken sheet metal screws and the end of a ramrod .......... stuff like that

 

[coloradoclyde]

Check for obstructions, but I'm betting on the fact ramrod is hitting on the patent breeches.

Why they ever invented them is beyond me.

 

[Grenadier1758]

I'm speculating that there is either a bore brush down there or a stuck ball that has been drilled though as part of the effort to remove it.

This barrel probably should have the breech plug pulled and the obstruction driven out. Time for a visit to a black powder gunsmith.

DS:
You need a vice, leather to pad the vice, a t/c breech plug tool, large vice grips and a 2 lb hammer. It ain't rocket science to remove it. If you can't borrow a t/c bp wrench out there, I'll lend you one.

Ditto in all respects. I lined my vise with sheet brass instead of leather. 10 minute job. I used a huge crescent wrench.

 

[good ole boy]

Why are modern m/loaders have b/plugs that are so hard to remove.How hard are they to reinstall and are the threads on the rifle and plug damaged in any way in the process?

 

[coloradoclyde]

Is it an investarms barrel ?

 

[davescott]

I assume its an early barrel.

only markings are:

THOMPSON / CENTER ARMS
ROCHESTER, NEW HAMPSHIRE CAL 45

serial #22563

on bottom it has cross mark ( + )

It seems to me that we're comparing apples to oranges. One barrel is a 50cal. while the other is a 45cal. Both would have a patented breech plug, with a cavity, however the 45 cavity would be smaller, and possibly too small for even the 45 ram rod to fit into. Now, I'm just making a wild guess. But, I would take a small diameter rod and recheck, to see if this would be a possibility. Just my 2 cents.

 

[coloradoclyde]

That's exactly what I'm trying to say. I disassembled a .45 investarms and was surprised at how far up the barrel the breech plug actually went.....like 2 inches or so, and the powder chamber was very narrow.

 

[FishDFly]

Why not send it to T/C for inspection, they made the barrel and have knowledge.

 

[tom deinek]

I am satisfied I incurred no damage. I considered making witness marks but did not do so using the octagon shape of the barrel for realignment. I did use so me kind of LocTite loosening agent on the threads in case I ever had to remove it again.

I did not find it difficult to remove; I used the wrench I bought with the rifle 20 years before. If TC sells the wrench, they must foresee its use.

 

[tom deinek]

I was retrieving a brush I had lost. I had tried every trick (break line tubing, copper tubing, various home-made & commercial hooks) I knew, had heard about or had read about without success in the course of about a month.

Don't use brushes in bp barrels!

 

[davescott]

thats about what im looking at..2" from the seam

 

[ohio ramrod]

If you are considering pulling the breech plug I suggest you soak the breech area well with either Kroil, or a mixture of acetone and automatic transmission oil 50/50. If it is a percussion just put a disposable ear plug over the nipple lower the hammer and stand the rifle in a corner over night with an ample amount of kroil in the bore. :idunno: :idunno:

From the seam :shocked2: can't get to my gun right now but that seems excessive.

Seems there is only one way to solve the mystery.

 

[Zonie]

For what it's worth, I own two TC Hawken percussion rifles.

One is a .50 caliber and the other is a .54 caliber.
The .50 Hawken is S/N K500xx. The .54 Hawken is S/N K2374xx.

Measuring the barrel on the .54 caliber rifle, I find the distance from the muzzle to the very faint split line between the front of the breech block and the rear of the barrel is 28 inches.
Inserting the ramrod until it stops on the front of the breech plug face in the bore measures 27 1/2 inches. Subtracting the second measurement from the first says the length of the breech plug threads is 1/2 inch.

The measured dimensions on my .50 caliber TC is exactly the same.

These measurements are to the face of the breech plug. They do not include the depth of the chamber in the breech plug.
They are accurate to less than 1/32" error.

 

[good ole boy]

Could you post a pic of the wrench?

 

[Scota4570]

I removed a TC 45 cal percussion plug a while back. With correct tooling is was no picnic. I I used close fitting rosined maple blocks on the barrel. I had the real deal TC plug spanner. I used a huge barrel vice. It finally took a large cheater bar and my helper smacking the cheater with a hammer while I put all my weight on it.

Some of the TC's are crazy tight. Mine was as if they just forced the plug to index rather than properly fitting it. Be ready for it. A bench vice, leather pad and a Cresent wrench are going to make a big mess. Unless you use the correct tools you will damage the barrel/plug.

PM sent.

If you think it will work, I'll loan the wrench to you.
