That is a very Asphoric question. Yes, I live in Louisiana, missed school, and had plenty of time on my hands.

Only reason he wrote STR is because we've been discussing this cannon through speech, not over the internet where you can see spelling.

Yes, it will be pretty expensive. Only reason it won't break 200 is because I gave him the pneumatics as a Christmas gift.

Also, why'd you get SCH-80 fittings? Just normal SCH-40 will do for a combustion. Even the 6" we got was SCH-40. Rated to over 100 PSI.

That is completely off the subject. I have made considerable progress with the igniter. Not only does it spark good, it made my whole arm go numb.

Yeah I know about the arm going numb thing :lol: ! Once when I did that I was carrying the camera flash thing in my hand with two wires hanging off it and I had it charged, I opened a door with the same hand as the flash was in ( not a good idea when the doorknob is metal ) and one of the wires was touching my arm and the other touched the doorknob while I was turning it and I flung the door and the camera flash into the wall. When the camera flash hit it shattered the capacitor and thinking nothing more could go wrong i stepped on a piece of glass from the broken capacitor :( .

I once tested a camera taser on a friend. He was weedeating around a pool and he was sweating. All these elements made it a very painful experience.

Oh my god! Did he get hit with the weed-eater and fall in the pool (and of course the sweat helped zap him)?

NO, he was touching metal on the weedeater and the pool had nothing to do with it. It was just serving as background.

I know this is off the subject but I just performed another thermite experiment. It was my best mixture yet.

I am still behind schedule on this cannon. I'm glad everyone has been opening up their stores so soon. I have everything except a definite circuitry set up and, of course, a 2" SCH-80 pipe for my golf ball barrel. I called place earlier that does stuff with oil wells and other high pressure stuff. I am expecting a call from them tom. If they dont have it I dont know where to go except ordering it or making a barrel out of two 2" SCH-40 pipes. I would rather have the SDR-21 sleeved with the SCH-80.

KARPA!!! I done told you once already, it's not NECESSARY to sleeve the SDR-21/26, (still not sure which one you got), in SCH-80!!! You can just get 2" SCH-40 and sleeve the 1-1/2" inside of it with duct tape spacers and epoxy.
