Had a barrel threaded with 5/8X28 threads.

[Kadams1563]

Is this an appropriate thread pitch for a 6.5 CM? I asked for 5/8X24 but the GS did 5/8X28 instead. What muzzle breaks will work with this thread pitch?

[darkker]

I have no idea what 5/8-28 is. Standard thread for .30-cal is 5/8-24.
Sounds like he botched it.

[Kadams1563]

Well I don't believe he botched it as he's well known. He stated that the X28 gave smoother threads?

[Rob01]

Well that is all well and good as long as what you are screwing on is that "smoother" thread pitch but if you have a can or brake that is 5/8-24 and want to use it then he botched it if he didn't clear it with you first. The 5/8-24 is the more common thread pitch.

not sure why he'd thread it 5/8-28 that's an odd size.

[Kadams1563]

Well I just got off the phone with him and he said that the steel was tearing instead of cutting. It's a criterion barrel By the way. He offered to make me an adapter for free but that irritating to say the least.

I can only assume that tearing steel has to do with damaged or dull cutters? I'm no machinist though.

Ross Schuler will do one for you in 5/8"-28. $35 shipped.

He also sells them installed on bare barrels for $65 plus return shipping.

[Kadams1563]

Lol... I know.

[clintsrv]

If I were you I'd request 5/8x24.
I want to know more about tearing vs cutting. I've never had issues with threading a barrel.

What all work is this smith performing for you?
Criterion barrels are quality pieces.

[Kadams1563]

Just threading the barrel and installing a muzzle break.

I would consider the resale value of this barrel should you sell it in the future. Since may guys are running suppressors, the 5/8-28 would be useless to them. If you instructed the smith to thread 5/8-24 and he did the other threads without consulting you, it sounds like he either needs to cut the barrel back and re-thread it, or supply you with a new barrel.

[darkker]

Right....
So you paid for standard, but got something else because it's "smoother", or ANY other reason. AND it wasn't cleared by you, FIRST. He buys the barrel, and never gets any more business

[sharpshooter]

If he was "tearing" threads, it wouldn't make any difference what the pitch was. Sounds to me this guy needs to learn how to thread.

[WinnieTheBoom]

what an odd pitch to thread a barrel. Can't imagine he'd have done that first without consulting you... Or he just really messed up.

[jetcycles]

Anyone that performs work for me, other than what was specified, typically wont ever work for me again. Tell your smith to man up and admit that he made a mistake and to make it right. Who is this "well known" mystery smith?

[Russmerle]

What was the outcome? Did he own up to the mistake? He should have never cut to different spec without your approval beforehand. I hope he owns up because it will be a hassle if he doesn't do right by you. At the least he should refund you the money and pay for another smith to fix it. A painter wouldn't paint your house pink without your approval if you originally requested beige...

[sinman]

There is no "smoother" thread. There are thread classes and that is what he should of went by and he should of cut it standard. Either he messed up and doesn't want to confess or he's a moron and when he said the metal was tearing I would say he doesn't know what he's doing.

[Kadams1563]

I'm not one to bad mouth a person so I will leave his name out. He did excellent work and the brake looks good. Just the threads are off. It's not that big of a deal to me as I won't be changing breaks or suppressing this rifle (well not anymore). I was just curious about the threading. I wish he would have done the planned threads but if I wouldn't have asked I never would have known until I tried to screw a suppressor on.

[Rob01]

Why don't you just have him recut the threads to what you want? Yes you will lose about 3/4-1" of barrel when he takes off the threads he put on but it will allow you to do what you want with a can or brake. He should do it for free as he changed what you wanted without your approval.

[geezerhood]

If he is having trouble threading on that steel, maybe using a die would be a better way to go. Turn down the outside to the correct diameter then use the lathe to align everything and thread it with the die. I have seen some folks get very clean threads by hand (no lathe) with a barrel threading kit from this place below. With the lathe it should turn out even better one would think.
