Hello,

I didn't even know that spud-guns/homemade pneumatic guns excisted until three days ago, but then I found this site and I got myself a new hobby...

So: I've just started with an attempt to build a QEV:

And first of all I wonder whether you think if it has the slightest chance of work as I hope?

If so, I want to use a blow gun as Pilot valve. BUT I haven't the slightest clue how to connect it? Any advices?

I will try to test it with an empty (plastic) soda bottle as pressure chamber to start with, but i haven't had the time to find a schrader valve and connect it to the QE-valve...

I would just bring the fittings to a hardware store, and see what will fit. You can find schrader valves as tire valves at, well, any store that sells car stuff. You should get a decent chamber, a soda bottle isn't going to hold much pressure.

i will work...at least as a single shoot. For multishoots the piston has to be machined....to feet well.
Look for "wyzz 2285" videos on youtube for a better understanding.... and more ideas
