Chambering a barrel

[ArtinNC]

Yesterday I watched a video on chamber a barrel a popular gunsmith chamber a barrel and he only indecated off the out side of the barrel and NOT the bore . Now that scares me about having someone chanbering a barrel for me . It needs to be indecated off the bore on both the chamber and the crown to make sure it is square with the bore .YOU AGREE ???? I give my lathe and mill to my son and he lives 500 miles from me .

Must have learned working for one of the manufacturers.

Opinions differ on how and where to indicate the bore... but never the outside lol. Was it a guy chambering 300 blackout? When you're looking at random youtube videos, you gotta remember that a lot of guys just have some old clapped out lathe and are doing what they can with what they have and no proclaiming to be experts.

I had an egg-shaped 7mm barrel not long ago. I don’t know if it makes a difference, but it didn’t inspire confidence. It was kind of a turd anyways when I started shooting it so I chopped it up to make other stuff with it.

If you are trying to get the best performance from a barrel then no, indicating from the outside is not the way to go at it. YouTube is primarily for entertainment, or so I've noticed. There's enough debate on gun forums to try and sort through without looking for advice on YouTube IMHO.

Was it Jim Green at"Downeast Gunsmithing" ? Cuz that guy is Hilarious to watch, I think that's why he went out of business, I think he's a nice well meaning guy, But I feel bad for anyone that had him chamber a rifle.

I had someone recommended that I watch his videos. Halfway through the first one I'd seen and heard enough. Quit listening to the guy who recommended his channel also.

I’ve seen barrels from .001” to .050” out of concentricity. If your dialing from the inside you get whatever you get..

Edit my brain fart, if you dial from the outside you get whatever you get..

Don't you mean from the outside ?

I remember watching a "master gunsmith" on youtube chuck up a bbl directly in a 4 jaw chuck and try to explain how to center up the outbound (steel) spiders. Those two things take a bit of barrel bending to accomplish since there was nothing but jaws (no pivot) on the barrel. I'd liked to have seen the marks those spiders left.
Same guy dial indicated to the outside.
Same guy tells his viewers that he takes big bites off each pass to save time and make money.
I quit watching at the threading part when he used layout fluid and then when he started threading about 1/3 of the barrel had no tooling marks on his first pass... probably due to saving time on those big bite passes with the barrel stub sticking out 3+ inches. I think he threaded or turned the shank down with WD40 as a lubricant in the same video.

Very hard to watch. Don't take your work to that guy and dont learn from him.

Basic engineering knowledge tells most people it's the wrong way.especially in a rifle barrel application.may be he's trying for a step in his chamber.

Good gunsmiths dont have time to teach you how to do their jobs on youtube.

Yes, brain fart. Outside

You would be suprized if I told you who it was ! BUT I'M NOT GOING TO .

 

[DonkeyHote]

I would say you need to watch this video. great equipment and tool, results speak for itself...

Don’t be too hard on that guy, years ago, his video about reassembling a Model 88 Winchester really helped me.

Mostly unrelated to the type of work and firearms we discuss around here, but Mark Novak on the tubes is a real gem.

It's PAINFUL to watch!

I dont know what you guys are talking about. I found that very entertaining.
