SLEEVE HAS BEEN REMOVED AND THE BLUING

[oneshot 66]

Purchased this, found a steel barrel with a SS sleeve and 8 oz. Sako trigger without a safety. Looks like the sleeve is glued on, I'm looking for advise on how to remove the sleeve. I used a barrel vise and action wrench, no heat. This a 23" original Sako barrel. Now to remove the old glue?

Heat gun or oven to make glue release. Never seen anything like that before.

Seems like more hassle than it's worth?

What is the first picture of? It looks like a bunch of material has bee removed from the barrel.

Sounds like a grenade if things went wrong.

New barrel time

My guess is your seeing the sleeve, then a layer of possibly JB Weld or similar and then the OEM barrel.

If I had to absolutely remove the sleeve I'd set it up in a lathe and turn it off. Best to put a new barrel on it.

That's what I'm going to do. There is some checking after the throat, but the rest looks good.

Someone removed a portion of the sleeve, don't have clue why.

To cool it down.

Sorry couldn't resist.

Nice welding job. They knew how.

I am willing to bet, this is what you are dealing with.

The author of that article was/is incorrect- JB Weld is a very poor thermal conductor. It's unsuitable for the heat transfer needed in this application.

May find a barrel rouged up with an 80 grit flap wheel under the epoxy similar to what is often found on an action that was sleeved "back in the day"

I had a very light 22 barrel and wanted to see what the sleeping would do in terms of accuracy. 5 shot groups shrunk from 1/2” to just under 1/4”. I don’t know that heat transfer rates are a big deal, unless you are running toooo many rounds too quickly.

I knew one guy who sleeved a military Mauser 7x57 for a silhouette rifle. He used a 12 gauge shotgun barrel for a sleeve. Seemed kind of half-assed but worked OK. I have sleeved a barrel with a drilled out original barrel. This to replicate the external appearance. If I had used the original barrel, including the threads, I would have been relining the barrel. Since I had turned and fitted a new barrel, I was sleeving it. A semantic difference, as much as anything. I drilled the sleeve for a pretty close fit and installed with high temp Loc-Tite. WH

I'd like to see if the barrel under the sleeve is the original Sako. I will remove the barrel and "SPIN IT UP" (why do they say that?) remove the sleeve on the lathe. I'll keep posting.

A 12" barrel block with an acetylene torch for heat takes a 20 ton press to get it to move. There is no pull.

Dave, that sounds like a been there done that statement!
