Have it calibrated a split second before you use it also,,,, TO BE DEAD ON BALLS ACCURATE,,,, its an industry term.
My first thought when reading this thread was My Cousin Vinny too.

Me thinks you're overthinking this.
That said, I think I need a 1/2" to interface with my flash-hider wrench. An adapter should work, shouldn't it, or will this create more leverage and apply more tq than the wrench is reading? Sorry, but this aspect of math is NOT my strong point.
?
An adapter will not change the torque, neither will a normal extension. basically, if it doesn't make the torqueing arm longer or shorter, it won't affect the torque. A standard extension on a socket, used to make the reach deeper, will not affect the value. A crows foot, which now extends where contact with the fastener is made and lengthens the torque arm, will change the torque value, unless it is applied 90 degrees to the point where torque is intended to be applied. Does this make sense? It's hard to describe, easier to show. Using a crows foot at a 90 or L to the wrench, will not affect the torque value. Anything other angle will.
I then contacted Wes of MSTN
That's who built my upper. It's been flawless.

To each their own. I prefer to follow Surefire's and MSTN's methods when suppressors are at stake.

So if I use the wrench in such a way as to place the point of contact with the muzzle device the same distance from my hand as if it were attached to the head of the tq wrench, it will not matter, but if the device "extends" the wrench, torque will be more, and if somehow it subtracts, it will be less?
bingo.
if the point of contact is the same distance on the horizontal plane form your hand (L shape), you have not changes the length of the lever and the torque is the same. If the short part of the L moves out or in, you have now increased or decreased the overall length of the lever, and your torque value has changed.
If you want to torque something properly, it is important to understand this, and from the looks of what I saw your tool looks like, this could be a factor. I am an airline mechanic, and if an faa agent saw me using a 12 inch torque wrench to apply 50 ft. lbs of torque set at 50 foot lbs with a 6 inch extension on the end of the wrench, I would now be applying 75 ft. lbs of torque to the fastener. My wrench would need to be set at 33.3 Ft. Lbs. to apply 50 ft lbs at the fastener, or I could rotate the extension 90 degrees, making the torque arm 12 inches
If you keep up that kinda talk, JWG is gonna try to make out with you.

That is correct the torque is calculated at the head of the wrench if the head of the wrench is extended with the socket you use, making the handle longer, the torque applied would be more than what the wrench is set to, if the socket you use is behind the head of the wrench then the torque applied would be less than what the wrench is set to.
without a picture this is the best way to explain.
s=socket
h=head of the wrench
a) s--h--------------handle you will apply more torque than the wrench is set for in this configuration
b) h--s------------handle you will apply less torque than the wrench is set for in this configuration
c) (sh)-------------handle you will apply the torque the wrench is set to in this configuration unless using a long extension to the socket
the only way configuration a and b would come into play is if you are using a crowsfoot type socket, that can extend or shorten the length of the torque wrench from the head of the wrench
if you are using a regular socket that does not extend or shorten the length of the torque wrench then configuration c would apply.
I need help with this. Other than the possibility of causing the head of the torque wrench to tilt one way or the other, I don't see how making the horizontal distance from the torque wrench to the flash hider or nut or whatever in my "diagram" below longer or shorter would change the torque.

That is the distance I am referring to. I understand that the lengthening of the moment arm with change the torque but I'm missing the other distance being a factor. Not saying it's wrong, just looking to make sure I'm not missing something.
