And some people prefer co-axial launcher to over-under configurations, and you can't use a QEV in a co-axial config, right? (except maybe as pilot).

What ? What use would toothpaste have if you can't use is to clean your teeth :S Or were you like, being sarcastic :O



















Nah, I'm just breaking yer balls, I guess, how funny am I, RIGHT ?!
Of course I know that Brasso is not for cleaning teeth, I'm so awesumm ...

BTB,

could you please tell me what brand of toothpaste you used, because my brass Zippo is becoming an ugly piece of smudge

Ahh ofcourse, area. How could I have been that stupid...
But does anyone has some idea's to mount a blowgun to a piston valve without quick connects and hoses and the like? Is soldering it reasonable?

I still have some unanswered questions about making a copper coaxial gun:


1. Is it a problem that the chamber is 22mm (3/4") and the barrel is 15mm(1/2")? Will a 12mm ( barrel ( smallest available copper here ) provide a better chamber to barrel ratio? Because it seems to me that using a 15mm ...

I am really sorry, I do not mean to take over this thread, but I have a quick off topic question, I have used the search button to no avail.

How does one install a blowgun into an endcap for piloting? Soldering ? Glue ? Seriously, I do not know :( I have no access to screw on endcaps or something ...

No pictures? Too bad, but I understand. I am planning on making one with a blowgun as pilot valve. The blow gun will be encased between 2 hollowed out pieces of wood and will double as cane handle, no CO2 for me :). Does it sound feasible ?

The range on the Decimator sounds amazing ...

That's an amazing gun you have there! But I am interested in one of your other contraptions, also. A while back you posted in a thread of yours that you are working on a cane gun.

I am very curious if you ever finished the actual 'cane' / wooden part of it? If you have I for one would love to see ...

Oh okay, thanks for the major clarifictations, all!

Oh and Gipetto, I thought of that too but I thought the increased pilot volume might be a very bad thing for a small gun, like my design-thingy.
But if it doesn't matter alot, I'll do what you suggested!

Thanks all, sorry to bother you all.

Wow, nice build there! It's very similar to what I was thinking of, but I think I'll make mine shorter.

You are not filling from the pilot side are you ? Do you have a spring or something ?

by the way: is it possible to hook up a schrader ( or smaller bike valve ) and a blowgun to the same ...

Oh, but I am filling via the chamber, via the little vertical piece.
I read somewhere on this marvelous site that that's alot faster than waiting for air to leak and equalize from the pilot space to the chamber ?

Is it very difficult to fill via the chamber?

Hello,

I am planning on making my first piston gun, and decided that it will be a handgun.

This is the design thus far:

The barrel is 15mm OD and the chamber parts are 22mm OD.
I will make a detachable bb-barrel for it, if I can find one ...

Cool idea,
I like the walking cane part :D

But the spring behind the piston, won't it release the air slower because of the fact that the spring must also be pushed back/ compressed (If thats the right word..? ) by the air in the chamber, or is that negligible?

If the spring would be powerful ...

Thanks for all of the advice people!
As for the disassembling advice:
Me and the guy who I made it with were already planning on doing that so we can have interchangable barrels, so that's quite convient actaully =)

As for you question, psycix, it's just for carrying it to the above mentioned ...

Wow thank you all, yes, even Thunderlord for the comic relief :).

Sadly I am not 18 years of age, but I never carry it loaded/pumped up or something like that.
But because I am 15 years old I am not even allowed to own it?

But to recap:

If I carry it concealed in my guitarcase, not loaded, not ...
