Home Forums Hunting & Shooting Gunsmithing Muzzle brake clearance

Any customer sees a so-called 'gunsmith' doing THAT and he/she better grab their rifle back in a nanosecond and beat-feet OUTTA that shop - like, FOREVER...:)

While this one was already threaded.
I usually go between centers and turn the OD concentric with the bore. Then indicated off of the OD. Yondering did mention that this is not the most accurate method, and this may be true.
I am gearing up to use a spider on the lathe, I'm just not there yet. My projects usually take months and even years because I am NOT a gunsmith or a machinist. I do spend the bulk of my time providing food, cell phone, education, housing, medical care, petty cash and in state college tuition for the 39,000,000 illegal aliens that are permanently vacationing in my country.

The statement that tuning between centers is not always as accurate as indicating off a tight fitting bore - rod is true.

However remember that the idea here is to have clearance inside the muzzle devise, be it a recoil reducer or a can.

So if you can indicate to zero tolerance on the bore, or get within .001" on centers ( a good lathe set up right will be under .001" many times) and then you cut the inside of the device at least .020" oversize, how would being more centered by .0005 to .001" make any difference at all?

It doesn't.

Some have speculate that the larger clearance on one side can compress the gas enough to off-set a bullet, but the Military's in the USA as well as the Germans the Austrians and the Swiss have disproved this.
