does it need to be air tight in the chamber and does it have to have and spring? if so should it be a compression or recoil. (push aginst barrel seal of pull away from barrel seal.)

sorry about the pic quality pimpman but maybe these will hold you over until i can fire it

sorry for so many posts

in the last pic you can see the max press reading and vent pipe on the top of the gun and the air intake and gauge is on the other side.

here is a few shots of the gun not good pics though

if this gun works fine and im pleased with the size and power i plan to build one out of aluminum with pvc stock and frame to prevent burning my hands. still havent got any pics yet but im trying.

i built a mini hybrid that has been under construction for some time. the chamber is 2'' and the female adapter fits snug aginst the 2''-1.5'' reducer coupling as so with the coupling and union. the only sch 40 fittings hold the ign handle to the gun. a 300,000V stungun to a dual fire sparkplug with...

right the young one is ahhh. see it i now do. now seen the light have i

no it is not a question more so a remark seeing as the is no forum to tell people about you gun without is being offical. i finished the paint job yesterday by the way. very nice

i built a combustion launcher that is shoulder fired with a missle toggle on/off built under the stock and a hidden on/off main bypass in the stock also. the pushbutton is in the pistol grip handle witch holds the battery for the 100,000V stungun. the chamber is 2''*3'', 4''*16'', and 3''*5.5''. it ...

take a 3'' male adapter( what i use to innerchange barrels luckly) the inside diameter of the threaded part is very close to the outside diamter of 2.5'' sch 40 pipe. i cut a 3'' pipe a little longer than my barrel and glued it in to the male adapter as normal. then i primered and glued the 2.5'' ba...

that is alot of air behind a 1'' sprinkler valve. i sugest building a smaller chamber or using dual sprinkler valves. the best solution would cost alot of money and that is a supah valve from spudtech.com or there is a theory article on how to build one on the site

how this for a privates engineering? this concept is completely origional except for boogiemans coupling and nipple combo. got to give the man his credit it is only fair. though im am sure he'll be proud of what i done with it. the SM-2 is going to utilize a multi barrel setup up to 3''. the main ba...

this is from the newly redesigned SM-2 that pic show the ign coil through the plug that is in the sch80 union(factory edge) the shaved edge is in the wye. the coil is 3/4 cu couplings around a 1/2'' sch80 nipple. this pic is the wye, handle, stock, and switchs. the 90 on the end has a cap on the bot...

1. any size wye fitting larger than 2'' and reduced to 1.5'' (smallest possible to fit a stungun.) 2. and peice of pipe and cap the size of the reduced wye.(for grip) 3. a stock can be made into the rear of wye or caped. 4. a flush bushing the size of your wye. (this goes toward the barrel of gun.) ...
