How did you modify the co2 bottle for the 1" porting? Is that welded? I've been wanting to use a repurposed high pressure tank as the chamber on my next build, but the tanks most easily available to me have threads smaller than I'd like and I'm not sure I have the resources for metal work. I know o...

Hi, nothing special here, just an ordinary "sawn-off" pneumatic :D - Valve is 1",BUSCHJOST, 24v Indirectly solenoid actuated Diaphragm valve (http://www.buschjost.com/pdf/E82860.pdf) ..it works just like QEV, no need to mod that valve, it has "build in" pilot valve ! - chamber is made from old carbo...

matti: That's a beatiful valved-pulsejet! Did you make it yourself, or purchase it from someone/somewhere else? I've been wanting to make a valved pulsejet, but have no access to machining equipment...and valveless are cheaper and easier to fabricate! Thanks DR ! that pulsejet is fully made and des...

this is the fastest that i have seen and used.. not sure how much those cost, but i have 1" valve and 3/4" valve, and both work very well

this is off topic but what does the 4/2 and 5/2 thing mean? since i don't know what the 4/2 and 5/2 means i cant help, but if any of them act like 3 way valves then you can connect it to a qev like this 4/2 and 5/2 means that if your valve is 4/2 the valve has 2 positions and 4 ports.. 5/2 then val...

Wow :shock: Nice valves you got there ... How have you got to get them? For a semi auto you would need the only valve that you dont have, a three way valve connected to a qev. You should think about modding all your solenoid valves to enable them to use npt threads like 1/4 inch to put a better pil...

Hi My english is not very good, so I put it short.. I need some good ideas what to build.. :lol: I have been thinking semiauto paintball gun or some kind of arrow shooting system (Im bowhunter so I have good arrows and knowledge).. problem is that for semiauto gun I don't really need those valves,bu...
