I'm About to Chamber My First Barrel; Any Advice?

[Bully]

Congrats! It'll only get easier from now on . Just remember to be safe .
It came out fine , once it's assembled the proof will be in the empty fired case .
You did it ! Be proud , now shoot, and enjoy .

Thanks.
Just waiting on the throating reamer to finish it all up.

View attachment 1059192 I so don’t want to post this pic.

The finish work I see on here blows me away. Additionally I know a couple of guys will be busting my chops via text when they see this.
I know it’s not perfect. But it’s as good as I can get it at this time.

Go easy please!

Torque that barrel in your action, put it in a stock and go out and shoot it today. When you see your cases come out ok and you don’t have any problems and your bullets are landing close together you’ll be jazzed. It will put a big smile on your face. After you know everything is okay then think about stuff like finishing etc.

Your thread finish needs a little fine tuning, but the rest looks good. Double check your shoulder/receiver ring abutment. Could be the photo, but looks like to have some small steps in there. Start on the inside and pull out with a straight cut across that shoulder. As long as it's all within spec, and concentric, it should shoot good.

Did you mention which barrel you used?

Now your screwed though, you'll want to get started on the next one sooner rather than later.

I’ll most likely shoot it prior to finish work. Again, I need to wait on the throating reamer.

Thank you. I’m bummed about the thread finish but they do work. I’ll be working on it on the next one.

The shoulder face is smooth. I checked it 3 times. I will check it again when I get home tomorrow though, just to be sure.

Barrel is a Rock Creek 1/7 .243.
This will be a 6BR set up to shoot 105 Berger Hybrids to start.

My most accurate hunting rifle is a Rock Creek I chambered in 6mm-06 imp. 1-8 twist. Shooting 105's @ 3250. I'm a fan of their barrels.

This is my second and I have a third on the way. Another 1:7 .223.

I think you did just fine. But if you zoom in on that pic the shoulder has pretty obvious steps in it. What i do as im turning the tenon down is hold short .015 then on the last pass i go to the correct length, plunge in just a bit then come back out with a face cut so the shoulder is only one pass and theres no radius.

Got it. Thank you very much.

Well, in for a penny.....

Here is the tool grind I use for exactly what Dusty describes

 

[alinwa]

Here is my current choice for cutting the bolt recess

 

[alinwa]

And here is what I'm threading with......it's carbide not HSS

I've tried 30 things at least and am currently cutting my threads at 320rpm instead of the 70 I useta'did

My guess for your finish is that you need to raise the tool a skosche to gain some top relief and remember to feed the last couple passes at just a thou and then re-run them twice without advancing the tool.

BTW Ya Done Good! I just get so flusterated with posting pix that I forget to 'splain myself sometimes.....

Be Proud

Weeee Oh 320 rpm threading up to a shoulder. Ought to be exciting. Seriously youre the dude with the prox sensor on his lathe right? Don’t know what rpm OP used but i dont think he wants to try 320 right away. Thanks though ill try it with a strait piece of stock and see how it looks. I’m always looking for a better finish

Bully
Some guys cut threads with their lathe compound set at 29 1/2 * , on USA made machines. The last pass or two they feed in using the cross feed. This cleans up the micro steps on the side of the threads.
As stated make a final pass or two without adjusting the dial.
All this varies on what machine you are using.
Looking good.

I think that you are speaking of Bamban.

I think Jay Christopher said he threaded at 600 rpm to the shoulder ! Used a metronome to keep the timing. I got scared just thinking about it !

Dave, it was no problem to thread at about any speed with my Monarch 10EE with ELSR. The machine did my thinking.
Speed is irrelevant to me as I do only a few a year now and I use Warner HSS threading inserts. If I had to make a living doing it, I would change my methods. I do thread without a thread relief.

Ok thanks for clearing that up for me
