Screwing a barrel

It's a swedish rolling block that has been sporterized. I am trying to refinish it. I consider that the best way to learn is to do it. Sending to a gunsmith will not help me. So that's why i am asking for advice! I've read a lot of things on unscrewing the barrel but didn't find much on putting it back on the receiver.

Now, if you know it, please share your knowledge!

If you screwed it off yourself and haven't modified the receiver or the barrel you should be fine to screw it back on.

I am sure one of the milsurp guys should be able to tell you the torque specs.....and kudos to you for doing it yourself, and realizing you need help, that is the only way to learn.
 
How did you get it off? You need a barrel vise and the correct action wrench to take a barrel off or put one on. Plus headspace guages when installing it.

Beside using lot of torque, is there anything i should do when i screw the barrel back in the receiver?

Thanks!

When I do this I wrap the barrel in rubber so I can get a better grip. Then when it is as tight as I can get it, I let my wife turn it a bit more.:D

My wife is very good at opening pickle jars that I have done my best to loosen:dancingbanana:

Just want to say i agree that doing is the best way to learn and asking questions is the best way to do it right ! good luck

....where do you figure the gunsmiths learned?
 
If you are able to get the barrel off, about the same amount of force will be required to install it.

If there are sights on the barrel tighten it enough so the sights are square to the action.

The torque used on screwing on a bolt action barrel is no more than about 140 foot pounds... and can be considerable less.

Pipe and Crescent style wrenches do not work for this. A barrel vise and a clamping style of action wrench are needed.
 
Maybe apply some molyebdum grease to the threads before you install it.

:) Makes it easier for the next guy who'd want to learn. :D

There are many things that can be learned by stumbling your way through them, but I'm not sure that installing a barrel to an action is one of them.

The best gunsmiths are machinists rather than home handymen. These guys routinely pay attention to tolerances that might be overlooked as unimportant to someone less knowledgeable. They have learned and honed their skills under the watchful eye of a skilled individual. They have invested in the proper tools to complete the job. I don't know fred, but from the way he worded his post I have visions of a guy with a bench vise and a pipe wrench.

Lets say that fred gets the barrel as tight as he can but he is unable to bring the index marks into alignment. He might choose to place a shim between the shoulder of the barrel and the action to resolve the problem. He might then loose interest in his project and decide to sell the rifle without ever test firing it to see if he has a problem; and you might be the guy who buys this thing.
 
If it is the original barrel going back into the original receiver, obviously it should be turned in until it is indexed exactly the same as before it was removed. If it is a replacement barrel, then it will have to be fitted, gauged, adjusted as necessary.
If you have not yet removed the barrel, part of the learning experience could be to make a barrel vise and receiver wrench set so that you have a chance of getting the barrel off with damaging either the barrel or receiver. These same tools will be used to replace it.
Even if you prefer to do the job yourself, it wouldn't hurt to visit a gunsmith, and ask to see his barrel changing equipment.
 
If you are just refinishing the rifle then you don't need to take the
barrel off.
If you must, then check for index marks, if non exist then make some up yourself and when reinstalling the barrel just line them up.

And IGNORE the self proclaimed idiot outhere net experts, most of them like to hear them selfs talk, umm type.
 
Ok, thanks for the info, everybody! Special thanks to Farmnut, Guntech, Brent and CyberK. And also thanks for the help, even if not always constructive...

The reason why i i need to separate the barrel from the receiver is because they aren't gonna received the same finish, i.e. rustblue for the barrel, case-hardening for the receiver - i know, the barrel was originally browned, no need to tell me!

If you ever worked on this particular model of rolling block, you probably noticed that the barrel have flat sides near the receiver: ne need for a 300$ barrel vise in this particular case. The receiver has large, flat sides too.

I guess i will take a gunsmith's course someday, the trade school is not so far from home!
 
Should have an indexing mark on the bbl and receiver. Line em up. If a rimmed cartridge it will head space off the rim so if the breech end of the bbl is tight to the breech block you should be fine. I took my barrel of with no tools at all.

Oh almost forgot when I screw a bbl I use lots of lube.
