oxy enriched mixes and non metal chambers dont go well together.

Enrich and DIE!!

im assuming you have a plastic chamber...

Nube question of the day, i know epoxy and hot glue pistons will work, but i dont have that.

I do have a butload of bondo (spelling?)

will that work?

ok guys, you ready for my spudstuff impression...

dont post in dead topics or ill eat you...

rar...

and i agree, the scilencer is a must for some good ole cheatin

I would use about 8 inches of three inch pipe.

that is about 1:1 C:B.

but thats just me.

If you want to go quiet or, you plan on using a fan/propane, i would reccommend 5-6"of 3" pipe. This is the .8:1 C:B......

or darn near it

uh oh, that may be my problem. crap. i guess my piston sucks.

anyone want to point me in the right direction to make a better one?

The piston is servicable. I seriously do not think that it is jammed, i have taken is out and messed with is a thousand times.

I have tried to get this gun to work for about two weeks now and ... i got nothing. so i need some help. it is a 4" coaxial with a 2" barrel. When I fill it up (50 psi) the piston seals fine. When I pull the blowgun, it doesnt shoot the stuff i put in there and i think it all comes out through the p...

pneumatics can soooo be very loud. thats relly only if you use a piston valve though. you should consider a modded sprinkler valve pneumatic. i use mine in state parks where rules are tight and patrols are frequent. it is very quiet, and if you use a lower C:B ratio you will definently get what you ...

No one at my school has ever built anything more than a basic hairspray combution. its actually kinda sad. and whenever i tell anyone about one, they think i am exagerating (which i am not). I introduced my friend to combustions a while back, and he loves them and has made his own. I am still the on...

i used this idea on a steel barrelled mini.

it works very well

if you want some help from the japs, and you want an suv, and you want decent gas milage,.....

honda ridgeline!!!!

we should. i was probably on the spudtech one and will eventually end up on this one.

we should also get DR back her to eat the assclowns alive.

one of my nay-bores.... always tells me to quit shooting my big combustion because it is too loud. so... whenever he is out of the house, i fill my barrel up to the brim with big pvc shavings (i have plenty, havent ever cleaned out my garrage) and i shoot about 15-25 shots over his flower bed. it lo...

a remember some sort of paintball mine that used a burst disk that blew after a certain amount of time. Maybe this action could somehow be applied to a parachute round. You would have to fire it off quick though. And the timing would have to be like perfect..... just an idea... :wink: ahh... here it...

Ok, I know that this is a stupid question, but I just want to be safe. So go easy on the newbie flaming.

I have a sch 40 pvc part, and a sch 40 UV-PVC part. If I use regular pvc primer and glue, will they bond correctly?

Can UV-PVC be safely bonded with regular PVC?
