wedge pin

[Tracy]

When I take the wedge pin out of my Renegade the barrel pops up about a quarter inch.If I loosen the tang screw the barrel drops into place.Should I put a shim under the tang or is there a better fix?

hotoSmile: Is the top of the tang flush with the top of the wrist?? If you install the wedge pin first, is the tang sprung upwards???

 

[Tracy]

When you push the barrel down to install the wedge it pushes up on the tang.The tang is not flush,it is inleted a little deep by the barrel.I don't have a clue how to post a picture,sorry.

If it is shooting okay- do nothing.

Hope someone with more experience can chime in. Best of luck to you Jess..............Daniel

You could bend the tang down a little more to get it more flush with the inlet. Just put in a vice and cold bend it, but go slow. Other wise, you could pad it and whack it with a dead blow hammer a few times.

Just corrected a TC tang barrel fit, actually two of them, a Renegade and a Hawken. The Renegade took some major work, re-inletting the tang down and moving the barrel back and down to install a L&R RPL lock.

On the Hawken there was a poor fit of the hooked breech to the tang. I filed a little on the hook and things fell into place.

These rifles are the first TC guns I have done any gunsmithing on and was surprised to find such sloppy work from TC. Stuff fit poorly, screw holes were stripped out, wedge pin holes weren't even close to being lined up side to side.

Take your lock off and put your barrel in the stock and see how the fit is between the barrel, tang and wood on the bottom of the barrel channel.

↑ That ↑
The tang should fit the back of the barrel flush for the best support.
By checking like Eric advises you will see if you need to re-bed the tang and/or the barrel in it's channel.
If the tang and barrel fit is off, then remove the tang too,, glue it to the back of the barrel and see how the connected pieces fit in the stock.
The T/C guns are getting pretty old now and many have passed through many-many owners,,Original parts are broken, damaged or lost and replacement parts are being mixed/matched to put together a full gun.
A lot of these older guns can be significantly improved with Acraglas bedding.

"A lot of these older guns can be significantly improved with Acraglas bedding."

I found that glass bedding halved the group size.

I am happy with the accuracy.Thompson Center has a problem with the stock cracking by the lock screw.I was worried that between the upward pressure on the tang and the recoil it might crack the stock.

From what I understand- you have a tedder-todder type situation. Tighten down the tang and the barrel near the wedge is up. Loosen the tang and the barrel is okay. And, when you tighten the tang the tang is below the stock (too deep). If that is the situation the most logical thing would be to bed the tang area. Any of the regular bedding compounds will work as well as some epoxy putties (it's a small area). Just wax or coat the tang and fill in the bolt hole- so it doesn't stick. I've even used a single layer of plastic food wrap as it seldom sticks (but still wax the metal as a safe guard.

 

[Col. Batguano]

If it cracks by the lock bolts it would be from over tightening rather than recoil. The tang bolt should be a little oversize in the rear, as there should be a slight gap behind the back of the tang. We're not talking a lot. Just a few thousandths. That keeps the recoil force directed to the back of barrel and plug rather than to the back of the tang or through the tang or lock bolts.

BTW; Is this a rock lock or a cap gun?

 

[Tracy]

It is a cap gun.

 

[Col. Batguano]

It is a cap gun.

Then moving the barrel around would be more problematic, (not to mention the pin / key issues, and muzzle cap) as you'd need to alter the hammer / cock shape too to maintain a proper cap strike.

Best bet is to get the tang properly shaped, and then bedded so it's got good contact with the bed when the bolt is fully drawn down.

Just to test fit the barrel, I would place a small piece of shim under the tang. Just a piece of card stock will work. You can use lipstick or something to create a transfer mark, to locate the area that is low. With the shim, in place, put the barrel back in and check for fit. If that works, then you can fix it more permanent with acraglass.

On the other had if the tang is fitting good enough, then I would look at the hook area of the breech and remove a tiny amount from that area to establish a better fit.

Wood can shrink over the years or someone could have switched out the tang or barrel. I have seen tangs, with epoxy placed in the stock, from the factory and it can fall out if a rifle is disassembled. People often remove the tang to drill it out for a peep sight or replace it with one that has the holes already in it.

Final thought, I would not want to pry the barrel down into the channel or have the tang not properly supported.
