SpudFiles

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?

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

nice build, firing vid plz

edit- spelling

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.

I guess so, And Im a pnuematic man, not a cumbustion anyway .
