C19O's Ghetto Mini - Version 2

[c19o]

Yesterday i made my ghetto bottle cap shooter. Well Heres version 2. It has a 3/4" sch40 barrel, pvc glued to a Powerade bottle as the chamber.I still got that empty bic pen to fire it but in version 3 it will be gone, and replaced with onboard propane (maybe), and a Push button ignition.
A propane torch is used to fill the cannon. 20 - 25 seconds for powerful.
10 - 20 seconds for medium. 5 - 10 seconds for a crappy shot. The guns favorite ammo is pine cones. Today I brought this thing up to my friends house to give him my old mini, and this one puts dents in his tin shed.
I didn't know a mini would be that powerful.

Nice gun, didn't know that 3/4" fit in a poweraid bottle that well. The ignition would be easier if the torch was self igniting, no need to install anything.

Thanks, i had to shave off some plastic in the bottle before i could glue the barrel in. And Version 3 will have a peizo ignitor.

Use a peizo from a lighter, BBQ igniters seem to wear out.

[c19o]

I had a peizo i was going to use, but i was shocking people in class and the teacher took it away.

Stupid teacher. Buy a cheapo lighter next time you are at a store.

[c19o]

Yeah thats what I thought. I'll buy a cheap lighter next time im at wal-moort

ummm yes very ghetto especially ur nice technically designed way of lighting it....nice gun all together though i suggest putting ur life before this thought id swith to pvc in this *v 3* or u mgiht end up dying....

[c19o]

i dont think the little pressure that this gun makes will explode the bottle. I plugged up the barrel and fired it, and it stayed pressureized until all the gas leaked away.

definitely get rid off your ignition set up otherwise a good design and i wouldn't change much except maybe putting in a propane set up
