SpudFiles

The specs:

1 inch x 2 foots barrel.

modded sprinkler valve(1 inch).

1.25 inch by 2 foots chamber.

I do "clay" shooting with it(throw a potato, aim and fire on it, lot of fun)

Its able to pierce 4 layers transport cardboard with .2 grams bbs(.2 are not enough heavy for this gun, i will need .3 or .4 ones).

There have been an error with pictures orders

Very nice.

Kinda like Daviadvani's Grenade Shells, but less... strong... and for things that arent airsoft-related.

Damage?

I am currently running to my basement to take so damage shots.

Actually this probably is stronger.

I think too: marbles go in straight line on 200 yards

(yeah, i know its alot).

and for the damage picture it is an dog food round.

Getting trough heavy cardboard with dog food!

Actually after running through the numbers they look pretty close in comparison when it comes to power.

Reason being is a burst disk is a better valve than a sprinkler valve and increases power but I have less chamber volume.

Cool creation!
I like the shells, though isnt it alot of work for one shot?

@david
Yep, yours is just in a smaller package, but the power is probably in the same range. Only difference is size.

Psycix:

The one you just see are the old version, i now only put 2 wads of toilet paper on each side. less time to make and same results.

but the plastic bag ones looks better

by strong i meant that the shells might not hold up to abuse as much as Davidvani's burstshells......

Looks good, and yeah, you have to upload the pictures in reverse order if you want em the way you had them in order.

The only thing I would comment on is the valve, it seems to have a narrow spigot-thing sticking out the top that was most likely associated with some piece of unnecessary hardware. I usually just like straight, frill-less, 1" Orbit-Masters. But, it's just an opinion, and it it works the same then it was all for nothing, right?

Good job on the cannon.

Ah that sounds good.
You could also add more plastic to them, to act as burst disk and make up for valve opening time.

Nope... the plastic bag is only maintained by an pressure of the electric tape and dont make any bust disk effect.

I mean, you COULD do that.
Add more layers (maybe aluminum foil?) and you'll have a burst disk.
