Judgement arms: thanks, i never knew those could be taken so high. I understand that LPA is quite sufficient, but i would like to make the gun much more powerful. The aforementioned semi auto piston will connect to the tank , and ride under the barrel so there is a place for the hopper, here are the...

actually, co2 is only dangerous in liquid/supercooled form- as far as i can tell. it will not be directly injected into the chamber, i know that is asking for trouble. the stabilizer/reg should take care of that, and if it does not, im thinking of more of a remote system(where the co2 is separated f...

Im not sure if this has been done before (besides the general setup of the semi auto mech.), but for the most part this is a product of boredrom. ok that is it for the moment, if there are any problembs, anyone can forsee, or any questions - feel free

ok here is the outwardly finished semi auto mech
inside, riding on the compression inserts is a peice of 1/2" copper, a spring pushes the assembly back to allow a paintball to fit, hopefully, the air will cause it to "blowforward", locking off the hopper

Ok, i am in the process of making a paintball gun using a combination of c02 and compressed air. My compressor can only go up to 125, and i have figured ill just add co2 as needed. this guns predecesor used a 3" and a 2" chamber, and a 3/4" QEV. .68 cal paintballs work perfectly in a 3/4" cpvc barre...

ive always wondered if this would work, or just make more fire. Line up 2 combustion chambers and link them together with the barrel and shaved bushings. have the first chamber resemble a normal one, but the second one should have slits in the top and bottom of the barrell towards the ends of the ch...

for a detailed description of how the slid valve and piston work go to http://www.spudfiles.com/forums/semi-auto-t160.html now for some changes the piston allows the tank to be filled up, but when pressure is equal, it seals itself. when you pull the trigger, the slide valve exausts the exta air, an...

Ok new idea, i think ive found the perfect idea for a semi auto. The base trigger design was inspired by clide, but ive changed it a little. Also i think that gobstoppers would be the perfect small bore projectile. ther'e perfectly round, kinda heavy for their size, and would be like bullets. best o...

what sizes of pipe are you using? is the smallest 1.5" for the body? and the slider/trigger 2"? also what pressure are you using in it?

that is by far the most ingenious and original thing ive ever seen for a potato gun

this way it could be like a spring, but you can change its resistance, and its cheaper. also you could take air from both sides

thanks spg, but ive got another idea. what if i were to place a plunger into the tank, and have it regulate the pressure as the pressure in one side increases, the plunger will move to prssurize the other side.

actually i would love to be able to fire this thing like a paintball gun, if there is any way to replicate that

i know i didnt explain i tright but the 1" pipe should slide through a shaved 1.5" to 1" coupling. the 1.5" pipe is just to hold it there. i guess its not a real bolt since the barrel will actually move. the 1' repair coupling isnt supposed to go into the 1.5" inch pipe, just kinda slide between... ...

ive been trying to make a new rifle but i cant figure out a good way to get more than one shot out of a chamber(without halving the presure each time). The only way i can figure out how to do that is by having multiple tanks. Ive already made a new way of breech loading. It uses a slide repair coupl...
