My 1st phneu 2nd cannon so far

Unread postAuthor: kwinche » Thu Aug 17, 2006 4:30 am

Hay
This is my 1st pneumatic I is just a plain old inline im going to mod it in to a UO sniper with a stock but ATM I only had enough for the bare minimum
Thought I'd have to make 1 after making my first combustion 3 weeks ago.


HAS NO POWER wont Evan throw a piece of potato across the road, and it takes about 3-4 seconds to let the air out of the barrel after clicking the button, I'm guessing its because im yet to mod the sprinkler valve, Although it dose do some spectacular water shows it will spray water 15-20 m up in the air.

it consists of:

a 1m length of 32mm

a 1m length of 25mm

some bits and pieces to get it to the right size for the sprinkler valve

and a gas tap with a 1/4 nitto fitting for my compressor

Every thing is pressure rated even the reduction bits and couplings, I didnt skimp out.
Its relay strange I was going to make it bigger e.g give it a 3" chamber and a 1.2" barrel but I cannot find bushings and the other bits and pieces (im in Australia) I got all my components from a pool, pumping and irrigation supply shop.

there are a few thing i will do in the near future
as I said before make it UO
give it a stock
a paint job to get rid of where I doused primer all over the pipe with a rag
cut pipe back and put a new end cap on it look at my pic
mod sprinkler valve

dont flame me for not sodding the valve like a kewl I know that it should be done but I ran out of money

Because this was an imperial fitting and i only had metric drill bits i went 0.5mm to big so i epoxied it it leaked put paper around it and added more epoxy works well now. I'm going to get a new end cap and redo it

try heavier,harder ammo and it should go further like a marble or something,a big chamber will help and a better C:B ratio will also doa bit as well as modding the valve,
average cannon for a 1st pneumatic could be better but on a tight budget not too bad 8)
