Butane badness

Step 8 Usage

Firstly, study, memorize, practice, recite, remember:

Gun safety:
1. Every gun is always loaded.
2. Never point a gun at something you do not wish to see destroyed.
3. Keep your finger off the trigger till your sights are on the target.
4. Be sure of your target.

I could tell stories illustrating how each of these have led to negative consequences when violated. Remember them. Practice them always. Read them again.

When I assemble the device I usually set the lighter gasflow lever setting to the middle. I find that three half pulls of the trigger sends in three puffs of butane which is about perfect. I wait or not, and pull fully the fourth time. Showtime.

The performance of this device will amaze you and astound your friends. I can shoot minimarshmallows through both sides of a cardboard box. Printer paper folded a-frame is penetrated through both sides by a tic-tac while remaining standing still. This usually works with two such a-frames i.e. penetrating 4 layers of paper.

I have better pictures...but there is a deadline to meet. Stay tuned.

Tic-tacs to the skin - OUCH. Marshmallows? Yikes.

The longer the barrel, the better the performance - within limits. I have not yet fully explored those limits. Stay tuned.

Cool design bro.I just made mine but with a few tweaks.I took another canister,fit 5 mini tubes inside,Ok well to make a long story short its a revolver.(but you have to turn it manually)For you crazy James Bond types,check out Pneu-Darts.They're tranquilizer darts and pretty cheap(couple bucks apeice).They are empty so you can fill them with whatever you want and anyone can buy them.I haven't done it but think about the possibilties.I think the site is just Pneu-Darts.com,but if not just Google.One more thingMini nerf darts fit over a pen plus you can add all kinds of neat gadgets like a syringe or capacitor.Use your imagination.Have fun:-)

can u send me a pic of what yours looks like? If u can't its no big deal. just wondering. :)

Okay, followed every step till now. The butane fills the chamber, the spark arcs across the wires, but no bang! Any idea why I can't get the gas to ignite? Too rich/too lean/not enough oxygen?

[jeff-o]

Nevermind, it was a bad air/fuel mixture. Anyone who is building one of these must really pay attention to that, otherwise the butane won't ignite. It's also important to have some sort of air purge system in place, be it a syringe or breach-load chamber, that allows you to fill in fresh air for each shot.

Blow off the smoke like they do in the movies...

Yep. Happy shooting.

A couple check valves could possibly make for an auto-purge. Have a check valve to only let air go out of the barrel (it'd have to be placed behind the barrel,) and to let air in to some other part of the chamber. When the butane ignites, it expands, expelling the projectile out the barrel. Momentarily later, what's left in the chamber cools down and contracts, drawing fresh air into the chamber. Biggest problems I see with that are that the barrel check valve will probably be too constrictive and slow the projectile down, and also the valve will probably get torn up quickly (assuming simple home made valves.)

can you tell me what exactly what the syringe does? I have one and I would like to make use of it.

[ccallumm]

lmao druggy

The syringe was modified to become a pump. I used it to pump air into the chamber after firing to purge the products of combustion and prepare for the next shot. This was supposed to be an alternative to opening the chamber to vent it. You need to create some valves so you are moving air only 1 way. With just a syringe you will be pulling air out of the chamber, then putting the same air back in. I made my valves with some latex membrane and glue...they worked great. Good luck!

i saw a video of a police instructer shooting himself with a gun that "wasn't loaded"

[bench.worker]

Exactly.

Every gun is *always* loaded.
