I really like flying rc helis but my favorite one and the one I've used the most a picooz type heli they are fun to fly, charge in minutes and really easy to learn. They are also nearly indestructible, and if you somehow manage to damage one its fun to mod it and optimize performance. I think a mini...

No i trigger it with a blowgun but i decided to keep the solenoid just incase I ever wanted to change.

This is just a really simple sprinkler valve pneumatic, I just sorta felt like posting. Pretty self explanatory, chamber is 1.5" pvc and barrel is .75" pvc with a .75" sprinkler valve. This is my first sprinkler valve pneumatic.

Approximately 830psi if I remember correctly, and quite cold. I would never use this without a pressure gauge, safety popoff.) I do have a pressure gauge and pop off release valve, I used to take it up to about 70 psi before firing and it would only take a seconds to build up that pressure if I put...

I don't know if this is illegal on this site or anything, but has any one else tried using dry ice as a fuel for their gun. I modded one of my old pneumatics to run on dry ice and water, it saves me a lot of pumping and could get up to relatively high pressure. I would post a my dry ice cannon but I...

Have you got anything to help make a good seal between the barrel and the airsoft bb. Other than that looks pretty cool.

Ok so I decided to lose the pump because it was a waste of space and effort, instead a put a very small fan inside my handle and added a battery pack and switch.

Are there any suggestions on a cheap easy way to measure out a consistant fuel supply.

I am working on a way to meter the fuel, i just added a pump to clear out the chamber, and I am waiting to find an old lighter or something to make a attached fuel source. I also just made a different type of barrel that is easily my favorite, its basically just a film canister connected to a water ...

I just put up some damage pics, they're not too impressive but I am shooting this thing in and around my house so it cant be lethal.

Is there a fuel that works best for a small combustion gun? I have used butane, hairspray, and axe as the fuels and they all seem pretty similar.

Thanks, I just added a new barrel on and increased the range and speed by a lot, might try posting damage pics in a little, but I'm still working out the kinks so it could be a day or two

This is my first post and my first attempt at a combustion gun. I had a bbq sparker and I already have a large pneumatic so I i decided to try a little combustion gun that i could use for shooting airsoft bb's or spit balls around my house. I think it turned out pretty good it serves its purpose and...

I have been thinking about making one of these too and i thought you could do something with magnets, maybe a magnet with a nail on the end in a tube, then glue the tube to the inside of the chamber. Then on the gun part you have a magnet connected to a trigger this magnet pushes the other one with ...
