This is going to be my first pneumatic cannon it is based on this design
http://www.gizmology.net/pbm.htm
It has not relay been altered except from the air input, I also liked the design of the semi auto cannon in the Pneumatic Cannon Showcase called the "SLIDER" but instead of having a piston i am use going to use a pressure chamber and a moded sprinkler valve.
It will also be a marble gun instead of a paint ball gun, as i have no assess to paint balls so it will need a 1/2 inch barrel.
I need a few q's answered
1. How many shots will i get from a 3foot 3" chamber at 100psi
2. am i using the best bolt assembly, or should i use one similar to the slider or another design.
3. I need a bit of help with the parts I understand the theory but I haven't used pressure pvc or much pvc as a hole so i need help with that.
4. this goes with 2 & 3 the design i use will depend on the ease of getting the pars and the least machining thats going to be involved as this is my 3rd cannon
5. This is just your opinion should i go with an over under or a straight barrel/chamber design
Hay thanks for the help and i don't wont to come across as a newb and please don't pin me for not reaching as i have done alot of reading of this forum and others
Thanks Kiwnchee
