the screws dont necessarily seal the tee off, its the tightness of the o-ring(s). The screws just hold the plug in the tee.

i suppose you could use it but its strongly discouraged. DWV fittings are typically designed for sink drains and shit to sewer. Spend the extra dollar or so and use pressure rated fittings. Like spudstuff said, they can be fine for one day and blow the next.

That sucker is burnt! This happens when a cannon is ignited with the cap off and continues to burn, it has been used a whole lot, or the cap/cleanout adaptor cooled much too quickly when molded which made the whole part(s) shrink. I would suggest tossing it away because you will probably end up blow...

www.preventsecurity.com has them for dirt cheap, 100,000 volts. I bought so many because I take them apart and assemble them into the box shown above. This makes it legal to sell to customers in stun gun restricted states because its no longer a weapon, it is considered an ignition source when its t...

The problem with stun guns is that not everyone can buy them, or people think they are too expensive, I just bought 20+ stun guns and they cost the SAME as a bbq ignitor. The spendy part is when you want to make it into a good looking attachment for your cannon, and replace batteries a lot. I hate t...

well, thats why i say to hard boil till they crack, some water soaks into the egg. If they are not hard boiled they dont freeze as much.

How about this for some destruction/penetration/damage? ammo used was frozen eggs. First hard boil the eggs till the shells crack, and then remove the eggs from the water (carefully). They load into a barrel just like a spud, except they are a lot harder. This works perfect with some eggs that have ...

wow that expensive one looks sweet, it pumps a tire up to 100 PSI in 10 strokes. But if i had to spend $100 on air pressure id simply buy a small oil free air compressor

unless you want to go really big you shouldnt really have to worry about the air flow choking from the QEV's 3/4" outlet. If you want to make a huge cannon like joels mega launcher you are going to need a pair of piston valves. If you wanted to make a smaller version the QEV's will be fine up to a c...

absolutly, the ass end of a blowgun is 3/8" NPT, the quick exhaust valve is 3/4" NPT. You will need a 3/4" to 3/8" flush bushing to connect them directly, but you will want to buy a tee to connect the blowgun and a schrader or quick disconnect, or both (to pressurize it) feel free to send me a priva...

grill ignitors work pretty simple, there should be two wire leads from the end opposite the button. One is on the very tip, the other is on the side about halfway. The side one is the tricky one, some bbq ignitors have a thin wire, others have a little tab. The tab one is easy because you can put a ...
