Alex, torque values for $100, please..

For what it's worth, I've been involved with several problem child rifles that were magically 'fixed' after picking up the barrel torque. ;)

Obviously too many individual factors at play to make a blanket statement about every gun, of course.

I do a witness mark on the actions and barrels where they just come up as tight as I can snap them by hand, then another mark when they're torqued to what I use. On all of them, I use a bit of Dykem layout fluid on the face of the action/lug beforehand to get an idea of the contact.

Good shootin' -Al
 
I'm looking for opinions on how folks put barrels on actions... Talking about SS actions and SS barrels here.

Question is about lube and torque value, but mainly the torque.. Do you snug them up by hand or quite tight? Torque values if you use a torque wrench...

Jackie, I believe in the past you decided somewhere around 125 lbs ft... If I recall, Gene agreed with that.

Anybody ???? TIA!
I would lube the threads and contact surfaces with Molykote-P37 and torque to about 100 lbs.
 
This is kind of like action screw torque in my opinion. If the bedding is good it should not make a difference so long as its not loose. I dont use a torque wrench I use a t handle. I just put them on tight. Same goes for action screws. The lug nut reference is what I tell customers and if they want a value I usually say 75-80 pounds. Do I think there is a difference between 75 and 100, no. But I wouldnt do less than 50. So far as grease, again Im not sure it matters I just use the one that has been used on the rifles that have broke the most records, lol. Just more of a superstition. I have not done real testing in this area, I just am going with what I know has worked for some exceptional rifles. If the machine work is good, a barrel torqued to 75 will feel like it was at 200 when you crack it loose. Im not concerned about any movement in the joint.
 
Seeing as how most of the best shooters and gunsmiths use a t-handle, and most guns that win have barrels installed with a t-handle, i’ve concluded that torque doesnt matter. Ive seen guys hang off the handle like a gorilla, and ive seen guys snap them on hand tight at a match and both have won. Just put the barrel on and push on the wrench and be done with it. Have you seen a kelbly port wrench? Theyre aluminum and have an 8” handle. You aint putting 100lbs on that and kelbly rifles win all the time
 
It's like my girls yoga pants. Tight is tight. Doesn't matter how tight it is as long as it's tight. Tighter than tight enough is probably going to cause problems you can't immediately see.

When we're building engines or assembling something that has torque values, they're important because you could easily over do it, or because there are several fasteners that need to be the same (head bolts) I had a suspension bolt that called for 110ft/lbs. I could have gone past that, and the bolt would have kept turning, but it would have caused harm.

On something as big and tough as the actions we use, once it stops moving, moving it more isn't going to do anything over than stretch and stress things that don't need to be stretched or stressed.
 
Decades ago, with the typical 1.062 diameter threaded joint, I settled in on 80 pound feet with a thin coat of anti-seize, with emphasis on thin.
Like Al Nyhus, I also place a witness mark with a sharpie pen to insure the barrel did indeed advance on the action After a firm seating.

I have also cured more than one ill shooting rifle by simply tightening the barrel.

I really don’t argue points such as this. If a rifle is shooting up to it’s capabilities, over tightening the barrel will not enhance it’s capabilities. However, if it is not sufficiently tight, the rifle will never shoot up to the capabilities of the assembled components.
 
I had some grease dry out on my P. dog and Ground Squirrel Rifles that I shot very hot, very often, so I like a high pressure, high temp moly grease.


Another issue are Non trued Remingtons with factory recoil lugs, I torque them 80-100 ft/lbs where headspace does change a tad, and I finish them by hand.

Feedback would be nice on this "changing headspace" issue which seems unavoidable since the action face is not square, nor is the recoil lug. Seems like a shrinkage of headspace of up to .002 is the norm, and this is what I plan for.

I use a Kelbly or Davidson Port action wrench when the barrel is in the lathe, then go to the barrel vise later on.

Obviously, I am a hobbyist and do not do work for others.

Amen, Jackie. As Mike Ezell posted....once it's tight enough, any tighter is just tighter. It's the enough that we have to determine for our own situation. The camera angle makes these marks appear further apart that they are.

Can I get a witness???? ;) :D

If they are slightly closer then they look. That is about what I get torque to 70 ft lb.
