Fake cans?

You know when your mommy said there were no stupid questions? Well she was wrong.

14mm thread fits 14mm while 1/2x28 fits ...... you guessed it, 1/2x28.

There is no such thing as a metric equivalent of an imperial thread.

hey smartass,
Consider this : i know NOTHING about machining. And as there is a metric equivalent of pretty much EVERY imperial measurement out there, it is only logic to assume for a person like me who knows nothing about the topic that there could indeed be a metric equivalent.

You could have simply answered my question and I would've thanked you. Instead you choose to be condescending...
Nice. Quite the show of character.
Maybe you can ask your own mommy why she raised you to be a jerk to people who ask questions you know the answer to?

Well, I was about to make a smartass comment, but suputin beat me to it...

Consider this: 1inch = 25.4mm, so 1/2inch = 12.7mm which interestingly enough is the major diameter (the biggest diameter) of a 1/2-28 UNEF thread:

http://www.efunda.com/designstandards/screws/unified.cfm?start=64&finish=147


...you have a gun I am assuming, you know how caliber works (also assuming), so a .50 cal rifle is 12.7mm, a .223 is around 5.56mm, a .30cal is close enough to 7.62mm

OR: 14mm = 0.55inch (okay, so here's math: (1in/25.4mm)x14mm = 0.55in)

Now Metric M14x1mm thread starts with a 13mm hole, so it will be a little closer than above, but still - 13mm hole, 12.7mm peg... :)

Now you can't say you know nothing about machining! :p

Thanks for the info autocrash. I did look the 1/2" metric conversion before asking the question. The thing is, with one of the guys in this thread (no pun intended) mentionning that he had indeed installed a 14mm can on a rifle, I thought maybe the tolerances where "loose" enough that it could fit...even if 1.3mm seemed a pretty significant difference.

So just to make sure, I figured I'd ask. He replied to my PM saying that the rifles they were installed on where also tapped 14mm.

There's no reason why I or anyone should get a smartass comment for asking such a question. On some topics we are less knowledgeable then others, and it is only normal to try to gain more knowledge and ask about little details that may be obvious to others but remain not quite clear to us. Thats precisely the reason for asking. I do it, you do it, Suputin does it. Everyone does.

Its a real shame some people take the opportunity to adopt the know-it-all attitude and be condescending to feel bigger and better about themselves...

Don't ever forget that you weren't born with this knowledge, and that you were consequently also in a position at somepoint of asking the very same noob question. And if not on this subject, surely on another. ;)
 
The other part of 1/2-28 is the number of threads per inch: 28. Metric threads typically have a 1 mm pitch which makes them 25.4 threads per inch. (They vary.)

Historically, there has also been a large selection of thread shapes available. Fortunately most new nuts and bolts are cut to a standard. That's what autocrash's UNEF refers to.

I'm getting old; can't even remember what UNEF means. Sigh. :(


PS - just saw your last post. Would not have included this if it had been there when I started writing. Hope you know respect is implied.

Thank you as well Kveldulf! much appreciate the extra info. Very good to know.

My last posts were a direct response to Suputin's rude answer. Your post and others are actually quite the perfect examples of what normal, respectful people do when asked a question they are comfortable with. Lets hope he sees that.

:cheers:

This is true... I'm just a smartass :slap:


Sometimes to my detriment... :p


FWIW I am pretty sure I have seen airsoft cans that use a proper 1/2-28 thread as well... can't remember where though... and that seems really close to breaking some law, I'm sure... :rolleyes:

Wish we could just buy real cans...

So what do you classify "tin cans" as? :p

Turning into an anti? :(

I as far from an anti as is possible to get. If silencers were legalized I'd be a millionaire in short order. I researched and wrote the Canadian paper on legalizing sound suppressors.

I have looked at a number of airsoft silencers and pulled them apart. They are as real as any suppressor and mounted on a real firearm would work quite effectively. It is only the weird M14 thread that prevents them being mounted to a real gun. As such it surprises me that CBSA allows them to be imported.

I am not against them being imported because the more people are exposed to these things, the more they are likely to ask why they can't have the real thing and the closer I get to lounging poolside counting my money all day. :)
 
Knowing how threaded fasteners work and are classified, even just the basics, is something all men should know. There's no excuse for not knowing metric and inch can't be interchanged. It's like changing a tire, or how to build a campfire. If you don't know these things, you aren't a man.

I am not the government but I can't imagine how a suppressor with a common firearm thread wouldn't be classed as a real can and thus prohibited. Even an empty tube with an endcap would work as the real thing.

Another classic case of Holier-than-thou attitude. Isn't that what highschool bullies do?

"If you don't know the things I know, you're not a man"....:rolleyes:

A man is someone confident enough about himself that he doesn't mind asking questions even it it means some a-holes will judge him and try to make him feel smaller for it. A man knows what he's worth and doesn't fear the judgement of others.

A man is also someone who doesn't feel the need to tell others that they are not worth as much. A man doesn't have to prove he is a man by telling others he knows things he considers to be manly.

A man is not defined by knowledge.
A man is defined by character.

I'll let both you and others judge what yours is.

Your "I"m shocked..." speaks volumes as does the critique of CBSA's actions. If you were as free minded as you think you are you would have said "I am pleasantly suprised..." or better yet keep your effing mouth shut. I can see why so many people get pissed at you now, where as before I thought you were one of the good guys.

Well at least the Mint must be on your side. Why else would they be introducing plastic money if not because it's waterproof? :D

Some "people" assume everyone grew up with the opportunity to learn the s**t out of everything. This is wrong.

I only learned of this topic because I had decided to take a year off and go back to school (studied in machinery) check around town if you know anyone who'd take the time to teach you a bit about threads. Lots of interesting stuff that will help you out for a long time!

BTW guys, no more mindless belittling/insulting comments in the thread please.

Ok then. Apparently I am not allowed to be shocked that CBSA allows importation of items that are a thread pitch away from being a Prohibited Device. That airgun silencers are not legal but an airsoft silencer compete with mount and baffles is allowed in the country. Not one bit of it makes any sense, not that I expect any sense from government.

I don't wish CBSA to prevent importation of these cans. I think it is amazing and hilarious all at the same time. I think that as airsofters grow into real gun ownership they will sensibly ask why can they not have silencers for their real guns when they had them for their airsoft guns.

My only concern is that people understand that just because an airsoft can is legally imported, it cannot be legally mounted on a real firearm because it is NOT a fake can. I'm not sure how many people will understand the subtlety of this bit of slightly obscure law.

If that makes me an anti and a bad guy then so be it.
 
Back on topic!!

Before the haters chime in, this thing is on there strictly for comedic value. So I'm not interested in your opinion of it because it's not meant to be serious, haha. And yes, it's a fake silencer AND a muzzle break! LOL

This is an excellent point. I'm not into airsoft or video games but I think they help gun owners more than people think. Anything that sparks an interest in tactical firearms is a good thing. Hell even Sons of Guns is a very good thing for gun owners...anything that makes people want to shoot is good.

I'll stop busting your balls. I have no doubt you'd like to see silencers legalized. I'd be less concerned about the legal ramifications of a using a toy/airsoft suppressor than the safety concern. As you are well aware suppressors are pressure vessels and need to be carefully engineered or they could explode.
