I can foresee a problem with keeping the ammo on the piston face. The bowl face may help but I still think it will just jam itself constantly. Also, will the solenoid actuate a piston to actuate another piston? Seems like an unnecessary step to me.

In regards to new weaponry, I think it would be worth looking into something along the lines of the +Bow.

A couple of "Sh*t did it hit me ?" moments I've had a similar experience with a battery and an open valve. I forgot to close a ball valve and was holding up the cannon while my friend pressurized it. I had the bright idea of putting my hand over the barrel and after a bit I began to wonder why I fe...

Some grease on the end of the barrel might help a tad.

Although it was stated many times, the hose does look to be a problem. A good alternative that I have seen would to simply use a small ball valve similar to that on the HEAL gun. It seemed to me like it worked well for that purpose, plus you wouldn't have the hose problem on this design. Otherwise, ...

Does anybody know what the white plastic piece he uses to hold the spring is? I have yet to see a part like that before and wonder if their is something equivalent. Also: with some help I can compile a list of parts he used and their Mcmaster number. 1x male x female x female T-joint: 9171K34 2x red...

Also, can anyone link me to the online seller of nerf-like footballs but were specifically made for paintball?

@davidvaini:

After looking through your posts on this, I am very pleased with what you have developed. However, I have a question regarding the specs of the cartridge. Approximately how long are the cartridges you are using now when fully assembled and at what pressure does the foil burst at? Thanks.

Propane meter for a proper C:B ratio.
Chamber fan for a better mix in the chamber.

just hitting the basics first.

Here is a basic diagram of what is being said.

Will popular vote be a factor in the judging and competition? I can understand the chair of judges to judge on preformance, but will there also a field that any member can judge on, like for the most popular cannon?

First things first, I am going to build a piston gun, especially now that I am inspired by MrCrowley's new piston gun. Afterwords, I want to try to develop JSR's Pre-Charged Piston idea. I'm fairly certain I can make it work. Drawings soon to come.
