Would this be a good design?

[Andrew_J]

Hey people,
I was wandering if anyone could reply some sujjestions about this design.
And would it work well with about 5mm balll bearings.

Please comment I haven't made many air guns and would like information
Thanks

Replace the blowgun valve is a slide valve.

30 psi is not going to give you a lot of power, it will be equivalent to an airsoft gun.

Thanks,
How much pressure should I have for ball bearing to get good power with a medium size air tank

use this -> http://www.thehalls-in-bfe.com/GGDT/
Use search function to find out how to use it

Damn we should have a FAQ or something, perhaps someone should make a video on how to use GGDT. I know we have a FAQ but I mean one that answers most basic questions related to spudding, not only using the site or logging in

How about a youtube video, that would generate some revenue surely

Yeah that's what I was talking about. Pretty much something like your video on syringe fueling. Unless you want to write a 4 page explanation of what each parameter is and what it does. We could probably make a thread that combines the most common questions we get and provide answers to them. Sure we have wiki but it doesn't really serve that purpose well

hmm... how does one capture a movie of one's own screen?

I use cam studio - it's free

There are some issues with settings (using default setting I got flickering vids and or voice problems), but once you get it right it works great

Hypercam...Google it.

Cheers, I might give this a shot

Yup been thinking about it, but I got other things to film. I feel there's a need for a long video explaining valves, both 3 way valves and QEVs as people often start threads just because they have problem identifying ports

I tried this set up and it just blew out of the air blower and didnt release or transfer air to the barrel. ..why how would you fix that?

Your piston is probably not tight enough.

The problem is you haven't made many air guns as you say.

Play around with your creativity to achieve what you want to achieve. I stay away from QEV's as they dump high pressure air into the open, when I could be using that air elsewhere.
