valveless pellet gun

[jackssmirkingrevenge]

The barrel's hard brass and the pellet is soft lead, it would take hundreds of thousands of shots before any wear would be apparent.

Now this is going to be fun to try in a BBMG.I have one in the works right now.Might have to play around with the idea Thanks Jack

[jackssmirkingrevenge]

I was going to try and make it for a BBMG but i realised that the same effect could be acheive much easier by having the BBs in the chamber and a ball valve between the chamber and the barrel

[goathunter]

Yeh, but something has to be said for doing it just because you can.I've got all summer so why not.

[jackssmirkingrevenge]

nothing wrong with that, good luck

On the other hand, I think it would be more interesting to apply this principle to a medium calibre launcher to give exceptional efficiency and performance, upgraded to say marble calibre...

Wow Jack your idea's are coming, it looks very simple to make. What kind of program do you use to make the diagrams or do you draw it?

In retrospect, I think a burst disc is a better idea as it gives you the opportunity to use any projectile you want even if it's not 100% airtight.

My diagrams are either drawn completely with MS paint or drawn with pen, scanned as line-art and coloured in with paint.

I have an idea for a bbmg.




Brown- chamber, barrel, and blocker
red- spring
green- trigger and sliding rod
purple- pivot point
black- rubber o-ring
yellow- bbs
blue- compressed air

Just get a bigger chamber more bbs and hook it up to an air compressor

Sorry, I am no artist.

[SpudUke5]

I dont think its a bad idea NewB. According to Jacks design, it should work very similarly.

[jackssmirkingrevenge]

That's pretty much a combination of my concept sketches, if you can achieve a good seal then it would work. In practice it's easier to just put a ball valve between the barrel and the chamber.

[NewB]

I think this would be easier to operate and quicker to open and close thus letting less bbs out.

[jackssmirkingrevenge]

Sure, if you can handle the increased build complexity. I decided it wasn't worth the bother

[SpudFarm]

i have acctualy thought about that a wile ago but i was thinking about a pistion thats hold back by a bolt then realest and goes in a bigger part of the barrel stops in a bolt that is in the middle of the bigger part then the air goes past it. it is pretty hard to explain

[jackssmirkingrevenge]

... and your linguistic skills clearly offer no assistance to the proceedings

[Novacastrian]

it is pretty hard to explain

Obviously

Increased complexity adds many a challenge, are you up for it my friend?
