Being a perfectionist is a double-edged sword. I know because I am one. And as a tool and die maker/moldmaker/machist with 40 years' experience, I've yet to see a self-trained man have a very good grasp of all the facets of metalworking. Unlike other trades, it takes an average person at least 10 years as a full-time machinist to be considered good. I've known men who in their entire lives never had the skills to be a good machinist. One thing most inexperienced machinists get wrong is tolerances. Knowing when it matters to be within .001 or .010 can mean the difference of spending ten minutes or one hour. Application is everything. So, with that intro I'd like to bring to your attention some particulars about threads. As simple as they appear, there are thousands of books written on the topic. It all comes down to the application. I know you understand all this, but there are a few things I think would help. First a depth mic. Without a proper measuring instrument mistakes can happen. Second, proper thread gages, both male and female. If you are buying parts from another company, you must have the gages to verify that their work is correct, as well as make your life much easier. Third, unless someone is going to stand on a wrench when tightening the muzzle brake, thread length of 3/4 minus .010-.020 will make absolutely no difference in the locking strength. This of course depends on the depth of the bore being .750. You are obviously going to apply thread locker as well which will stop vibration from loosening the brake, so a 1:1 ratio of thread diameter and thread length is just fine. In a perfect world, I would machine two flats on the brake and use a torque wrench with a crowfoot adapter to set a predetermined amount ensuring some guy doesn't destroy the threads and the tightening strength remains consistent. That is just as critical as the thread fit. Fourth, depending on the radius of the cutting tool used to make the undercut at the shoulder, ideally .015, you should cut about .030 under the minor diameter of the thread. And as you mentioned, there is already a radius on the I.D. of the muzzle which will ensure no interference. Once it hits the shoulder the two parts do not have to mate perfectly flat since the tightening torque will now apply pressure to the threads which is all that matters.
I've heard great things about Bartlein, Brux, and Krieger but have not yet acquired one. I'm still researching barrels but I own Shilen match and Preferred and I love those. Also own a Harrell press and a powder thrower and boy they are both sweet! Maybe I'll pick up a teslong scope too. Thanks for the video and I'm glad you got through the illness and are still with us Scott. I got it too but I guess I must be some kind of freaking alien because I didn't even know I had it, but I had 4 positive tests. Four of them because I didn't believe I had it!
Wow Scott , vickie looks fantastic. I’m so glad to see how well she’s doing. My wife and I are planning on coming to Idaho in the spring, we’ll stop by for a visit.
Another very interesting video...I saw this and later could not find it....I thought for sure that Vickie had kicked you in the family jewels and took it down! Carry on Sir!
One could Prussian blue either the inside of the break or the outside of tennon and screw it on and all of contacting surfaces would reveal themselves.
All I can do is watch In aww. A gun of this quality is out of my reach. Amazing work sir. Maybe someday I will find one at auction. Much like your bore scope one day I will succeed.
Excellent work! Love the attention to details, and glad you are recovering well!
Dear Sir - thanks........

Dear Sir - very, very good. I truly wish the world had more people like you. Thanks.......
I'm glad you over came the virus, you and your crew have a lot to offer!!!
Thank you

Dear Sir - for some people, China surprise is no joke. Thanks.

Dear Sam - she kicked Cancer's butt, six years and counting...........call me.
Another very interesting video...I saw this and later could not find it....I thought for sure that Vickie had kicked you in the family jewels and took it down! Carry on Sir!
Dear Sir - editing problems.........we need tech help just can't afford it. Thanks.
100% agree about the bore scope spinning ability....they need to incorporate it. Hawkeye's do...but for $1K plus....no thanks!
Dear Sir - Actually the professional Hawkeye model I wanted was over 5k - simply could not afford it. Thanks.
@@quarterminutemagnums Holy shitballs, that's A LOT of dough!
Thanks for doing a great video. J.
Dear Sir - Trying to improve our video quality..........we shall see. Thanks.
One could Prussian blue either the inside of the break or the outside of tennon and screw it on and all of contacting surfaces would reveal themselves.
Dear Sir - thanks.
lololol you are a lucky man!!!
Dear Sir - the grass always looks greener............thanks.
I'll say the brand...Hawkeye.
Dear Sir - could be.........thanks.
All I can do is watch In aww. A gun of this quality is out of my reach. Amazing work sir. Maybe someday I will find one at auction. Much like your bore scope one day I will succeed.
Dear Sir - save, save, save, thanks...................
Well you should know then, that he's lying about his group sizes.
Measure them.
Happy hunting, happy health = many more QMM videos!
Dear Sir - thanks............
Damn nice bull! Glad you made threw that CV BS.
Dear Sir - hard to find a big one in the back-country......wolves everywhere ! Thanks...............
You should not really sell you rifles, you should to auction them, you can make extra few bucks, sorry.
Dear Sir - maybe ?
Your rifles piece of art and I will want to get one from you and with this advice I'll shoot me in the foot! :)
Even more profitable than an auction, A RAFFLE!
