"SMG" Combustion

[blind909]

Ok, here is my first actual combustion(pillbottle minis dont count). The chamber is 2 inch aluminum(8 inches long), and the barrel is 1 inch pvc(8 inches long). The sparker is from a longnose lighter(larger than any other igniter ive seen). The sparker is housed inside a 1 inch pvc grip. That is pretty much it, Very simple. I MIGHT be making some upgrades.

DAMAGE PIC'S

Nice chamber how did you attach it to the pvc it kind of looks like its been taped on...

What kind of upgrades?

[blind909]

Attached be some sort of clear epoxy i found in my garage It slides over the threads, and then was glued. And upgrades as in a ball valve for fuel(right now I spray axe with a straw down the barrel) And A Daisy 4x15 scope. And I may also add another igniter right below the first one, so I can have a double trigger, and it will combust quicker, i think

[blind909]

A firing vid might be a while, same with damage pics.

What are you using for fuel and how are you fueling this thing?

I think the only thing I would've done this is try to get the spark gap out more in the middle of the chamber.

I assume you're shooting taters. Not a bad little gun actually. Nice effort.

Edit: OK I just read where you spray the fuel through a straw.

yup, potatoes, big marbles, airsoft buckshot, and bouncy balls.

Now my b!tch of a mom says I cant shoot this thing because she says it might cause a Fu*king fire. She can be one hell of a b!tch.

She's only worried for you dude, not like its a bad thing, shes your mother

You might want to move up to a bigger cannon altogether instead of just upgrading, a propane setup for this cannon would be very cumbersome.
