My new coaxial cannon(BLACK BEAST)

Unread postAuthor: x.X.Cpt.Rollhart.X.x » Fri Jun 09, 2006 4:59 pm

Here it is :D :D :D

It is currently in cure but I tested it with 20 psi, The piston seal perfect !

The chamber is 4" and 4 feet long, the barrel is 2" and 6 feet long. my piston is a 3" endcap.

here are the pics :

Edit :

I tryed it. dude it kicks ass !!!!

I shot a PVC dart at 1.1 km and I blow 2 cement beam with a 1" bolt with 2" washer.

I just did a very nice paintjob ! The stand has been done very quickly this is why it is a bit badely done ...

I couldn't tell from the pic. What's the gasket material. I'm prototyping a coaxial with 1.25" barrel, 1.5" chamber. A 1" endcap fitns but I haven't found the right gasket material and I get slow leaks just over 20 psi.

I see you figured out your bushing dilemma. Did that Spudtech thread help at all or was it all just a huge misunderstanding?

what do launch? big taters? i'd hate to make a mess inside that nice gun though. maybe those large bouncy balls that are sold on spudtech, but u could prolly find em at a dollar store or something.

EDIT: i now see 4" male and female adapter so you can clean out the gun.

by the way that cannon is hard core

with a sabot, you can launch anything.

And I will make some PVC dart ...

The person who made the P.A.C. 5 on this site pretend that he shot a PVC dart 1276 meter :shock:

I never believed that he shot his a dart out of his cannon 1.2km some one should GGDT his gun design n see the max distance.Because 1.2km is very far.

Do you need a sabot in a pneumatic to shoot water and flour and stuff?

What type of metal chamber is that?

I like guns that have like a 1" male out of the sprinkler and then a bushing to get it up to like 2" becaust then you can shoot golf balls while they're sheating on top of the 1" hole and they fire pretty good.

Not if you put enough pressure in the chamber to seal the valve first, and if you're using a sprinkler valve you don't even have to do that.
