Another valve help topic, xD

I haven't been active lately, due to finals, but hey, I'm back! After proposing my last idea, I need help yet again, incorporating JSR's valveless theory, I have a question. If my ammunition is 1CM wide, how wide does the barrel have to be to fire it? I lost the link to the valveless theory, sorry, ...

I'm going to take your advice and make a smaller version first, I can cut a whole into a duster bottle (empty) for a valve and then attack a barrel to the nozzle, meanwhile, I'm gonna draw down my current designs for my ambitious as hell BB-gun and make it when I have the funding.

CHEERS!

Also, I would like to pull back the top to load the first projectile, any ideas how I can make that work?(Also, doing it like this, pulling the slide back while holding down the trigger can make it full auto, I already think that a piston can be at the back to load the ammo, but I dunno how to make ...

I have one of those duster things where you spray compressed air into a crevice to dust it out, is it possible to get the trigger thing for that and mod it into a blog gun trigger? Also, the thing I need the most right now...is a job...I got no money, lol Also, with the O-ring seal method (valveless...

Multiple caliber means like nails, or bb's or something, and by meaning it'll hurt, I meant the piece of plywood I have downstairs in my basement, and when those stupid ninja pirates(pirate ninjas?) come back to get me...hehe. I still need some good designs though, I created one but I don't know if ...

I like the first one better, but I found one problem with it, it requires you to pull back the slide to reload. So this is my new goals -semi automatic/or maybe not? -compact -pistol sized -air tank in the pistol grip -doesn't have to be powerful, as long as it can really hurt at close range (10 fee...

I like JSR's concept, but instead of having the magazine on the bottom, I'm going to mod it so it goes on top, any ideas on materials and where I can find a blow gun trigger?Also, while at school today, I was inspired by something I saw, more on that later xD


Also, whats the dots on the barrel?

I've hit another snag, the only tools I have are hand tools, a jig saw and a dremel, I kind of doubt that just these tools can make this gun :(

Well, that could work, but I'm in high school, I can't just get any parts I want ( I'm job-less), and except for the hammer valve, I got everything worked out, so is my design going to work? If not, I'll have to use yours, but it's gonna be a lot bigger, I'll post up the full design later
