Barrel Torque Ludicrocity

@AccuSol-ERN - I got a beautiful BA from you a few years ago. Deviant and a Bartlein blank I sent you. What torque do you use on a barrel install?

@MikeRTacOps - yeah…not bc asking for your secret sauce, but do you torque your barrels to at least 100 ft/lbs or greater?

Thanks

Barrel Torque Ludicrocity

But it does flex, and is not rigid. There is clearance.
I said it's not floating. Floating and flexing are different. The way you have it drawn the thread wedge can move forward and aft in the joint without any significant load applied. In the action the ears must flex through significant preload applied by the locking screw. That load is translated into joint preload on the entire joint. The important factor in that setup is the ears have the same thread position that the rest of the tenon has. This means that when the ear flexes inward the timing of the thread flank doesn't change initially but rather once the screw load is applied to fold the ear into the threads. As the ear comes into contact with the barrel threads it moves as the driving contact on the barrel male thread. The tighter you make the screw the more force it applies to the ear, the farther the ear's thread drives towards the barrel and those threads form a ramp that effectively closes the PD down on the joint.

Since the joint is stationary against the shoulder plane the change in PD creates axial load due to the change in radial load. That axial load is the preload we're talking about being applied and acts just like torque to the joint.

All of this is because the ear does not move axially in the joint without significant load applied to it. It's not like a floating thread wedge like you might find in a locking ring on a Redding die body.

The flank may be loaded by the torque of hand tightening, BUT mechanism in the AWMC does not increase the tension in the joint.

If you put pressure at the arrow onto the chingadera, will it increase the pressure beteeen the barrel shoulder and receiver face, decrease it, or stay the same?

Most of the receiver is threaded normally(fixed), any squeeze by the clampc which is closing at the 6 oclock position, puts additional load on the already loaded flank. This is where the tensile load comes from. Its pulling the shoulder into the receiver face.

Barrel Torque Ludicrocity

The pressure at the shoulder increases. The wedge drives the barrel rearward and provides additional load into the shoulder.
The piece you're calling the chingadera isn't floating in the action. It's cut as a single unit to the receiver body and they have an H shaped cut that allows for the ears of the tab to flex. This means that the loaded flank continues to be the loaded flank and drive additional load into the shoulder face.

More lies revealed. Oil didn’t come from Dino bones 42 miles deep

Oil & gas is not made from dinosaur or any other vertebrate animal remains. It’s primarily comprised of phytoplankton and plant matter, pelagic ooze type stuff that has carpeted the oceans for hundreds of millions of years. Gets buried, compressed, trapped in rock. There is and never was enough biomass in dinosaurs for it. Now in the amount of microscopic sea and plant life…for sure there is plenty enough .
Yes, I’m a professional geologist of 21 years now.
O&G as we currently know and use from the CMB? No. Abiotic synthesis at CMB depths may produce some bound methane states like on Neptune etc due to massive pressures, but it’s not the same as in crude reservoirs at current exploitable depths. And you’d never get to it. It’s about 1,800 miles down. Deepest we’ve ever drilled is 12 miles. Good luck.
