This here is my 2nd spud gun made and it's a combustion.
It's chamber is made out of pressure class 12 PVC and various fittings that help put it together.
Barrel is made of 2 seperate screw-on pieces of pressure class 9 PVC that can also be detatched from the chamber.
I painted it with 4 black satin coats, one of the cherry red and orange for the fade and then I Clear coated it twice for protection :lol:
Im using a normal bbq igniter and it works fine, I dont really have any specs but it can put a hole through a keyboard and some 2mm tin put together at about 20 meters with a homemade projectile I made.
The reason I built it so it can break up into 3 pieces is so i can fit it into my bag and take it where ever, as long as no-one searches it. :roll:

This is a pic of my 2nd completed combustion spud gun, I had to mask it 3 times and ended up putting 7 coats on it.

Here's the fan that i added into the back and what caused the bottom end cap to blow off. (I think)

Nice Gun, its especialy good for you second one. My only concern is that you put the sparker into the gun which is not good. If it ever shoots out its going to take you finger with it. Over all it nicer looking than all mine! :)

Are you sure they are class 12 pressure parts becuase i have never seen class 12 pressure parts before and its looks very much like an all DWV gun.Its ohhk for use now but dont use it after its been siting around for a while,they tend to pop endcaps and such.

yer i recently put a chamber fan in it, turned it on while the hairspray was in and it blew the bottom cap off and ripped my t-shirt to bits. i think it shoots about 200- 300 metres, but im not sure coz i just shoot stuff over my fence.
