I would put the air inlet parallel with the barrel and with the inlet bottom tangental to the bottom of the vortex hole.

I am not sure what you mean by tangental

Anouthe Question if you dont mind. Must the Barrel and air in be flush with the inside of the Cap as shown in 1.? Or Can it be either?

To me it makes more scence if it is flush.

Please correct me if im wrong, but if the inlet was at the bottom of the vortex, then it would not create a vortex. Itthe air would run up into the BB Holder?

I was thinking of adding a threaded cap onto the end. I am still figureing out a trigger system though as im not sure wether i am going to use air or CO2. However i'm leaning towards CO2.

Hello all.

I am planning on makeing a BBMG, of Vortex Cap type.

I cant move the battery box as there is a shortage of space, nd wires The barrel can be quite easilt removed, as the prop...

Just heat the hose with hot water, and push it over the nozzle, and fasten with pipeclamp, or wire(It works better). Its simple, yet effective

This is my 3rd Gun, but first proper advanced combustion. The barrel is 2m long and 50mm in dia. It is sleved for golf balls. Chamber: 110mm Class 9, pressure pipe. and is 35cm long. It has a chamber fan, and a propane metering system. http://i279.photobucket.com/albums/kk133/Go-Boom/100_2820.jpg ht...

I had gballs sticking in my sleeved barrel. it kept on ripping the sleeve appart, until i sanded the sleve down more, now i have no problem.
