Do you glue the thread when you install a new barrel on an action? And if yes, which product do you use? - Thanks/Lorenzo

No glue.

-Spencer

The 'smith that does my barrel work uses a barrel assembly paste (Brownell's, I think). It's got moly disufide in it that helps prevent galling and seizing.

I don't use epoxys or lok-tite or any other type of "glue". Never found a need to and never incurred gauling either. Make the threads fit like a class three and install the barrel with your barrel vice and walla...go shooting.

No.

I'm a benchrest shooter and take barrels on and off like underwear. If the barrel and receiver are like material they're is a chance of galling. I use anti seize.I do not cut real tight threads as I want the barrel to square up to the receiver and not the threads. Butch

For the sake of the next owner of your rifle,
NO GLUE! If the threads were cut right there is no physical need for any type of glue. It is hard enough to get barrels off some actions.
Adding glue may result in the action being destroyed during someone's attempt to remove the barrel some day.

Disregard all of the above. Find a dead horse and boil the hooves down to a thick viscous fluid with which to coat the threads. After all, who can't use a little more horsepower?

I never have......

Butch,
Barrel threads and shoulder fit will mate both together unless there is a misalignment or runout in the action/thread axis.

Hello Jim, I'm not talking about a wobble fit to the receiver. I have seen threads tight enough that the shoulder was not square against the receiver all the way around. Pretty sloppy machine work! Butch

Butch,

I Blue Print actions and what you are describing has nothing to do with tight or loose threads. What you describe is either one or a combination of the following;

1. Receiver face not squared to the receiver threads.

2. Receiver threads not square to the centerline of the receiver.

3. Shoulder on the barrel not square to the barrel threads.

In a properly set up receiver the receiver face, the receiver threads, the receiver lugs, the bolt face,and the bolt locking lugs are all cut to be at 90 degrees square with the centerline of the receiver.

On a properly set up barrel the shank, shoulder and threads are all cut to be at 90 degrees square to the centerline of the bore.

If all those are areas are square the tightness of the threads will not be an issue in the squareness of the mating joint.

Rick, I don't disagree with you. I'm stating that I have seen barrels that had tight threads that would not mate properly to a receiver. We may be splitting hairs, but how do you square up a barrel in a lathe to insure it to be square to the bore? Where do you indicate when chambering, the end of the breech or where the throat will be? If you indicate both places and they are within .0002 of each other than you could have a shoulder square to the bore. Good enough for our purposes anyway. I understand what you are saying needs to happen in a perfect setting about axial and radial alignment. Most barrel bores are not straight! Again I'm not disagreeing with your premise, just stating that we are working with imperfect material and we do the best that we can with what is given to us. Butch

Butch,

Not trying to start a "thing" going here...but I am still waiting to pull a factory action out of the box and have everything on the receiver square to the centerline. They may be out there somewhere...but I guess my supplier is selling all of them to his bigger customers because I never seem to get any!

Rick you are correct in what you are saying. I think that they are getting worse. Butch

Butch,

If they start making em all squared up I won't have much use for all the Blue Printing tools I invested in though, and I'll have to start looking for something else to do with my spare time...and that could get dangerous!

Properly done, barrel threads are tapered and should be close but not snug tight until the last several threads..The use of that grey gunk that Brownells sells is very acceptable as it protects the threads from moisture condensation or leakage, whatever...I have seen many barrels hand tight and never had a problem with them, Jack Belk said a proper fitting barrel hand tight was all that was needed...I think he is right on that.
