OK, nice gun, buuuuut, and I'm surprised noone has told you this yet, 1. The two elbows are dwv, drain waste vent, and are not pressure rated. They will blow. 2. It appears to me that you mixed ABS and PVC when putting together the end cap adapters to the chamber. That is a no no unless you bolt the...

Grib's New Pnuematic & Ammo
Hey Guys, It's been a while since I've built a cannon mainly for the lack of decent ammo. I came across something that I thought I could use and actually found some PCV that would fit it perfectly. The Ammo: White Labs Liquid Brewers Yeast Vial (1 litre soda bottle blanks) Modified with a self tappi...

A Proper reducer is just that a proper reducer. If your chamber is 4" in diaameter and your bar...

I dont know about mounting your 9v batteries in the chamber. Seems like a bad idea to me. Here is a link to one of my combustion guns that has a chamber fan in it, held in place by two machine screws. http://www.spudfiles.com/forums/blue-bl ... 11441.html

The best way to do it is a couple #6 machine screws drilling through double layers of pvc or abs. put a nut outside the chamber and one inside the chamber and it will allow you to precicely adjust your spark gap. Then I attach the wires coming off the piezo to the spark gap. This takes away the forc...

Just because it says SCH 40, doesn't mean it's pressure rated. True True. Sch is just a way to guage wall thickness. Anyway, I have never used Pressure Rated ABS, mainly because I live in America, the land of the free and the home of Cell Core ABS, and I have never had a problem with it. Now this i...

The fan should be near the breach end of the gun so there isn't a large volume of gas, moving at high velocity, blowing past the fan's blades during firing. This is also to aid in installing and removing the fan as needed so one does not have to insert his/her whole arm into the chamber and get it ...
