Its a pretty nice gun and your using fittings that I've never seen before...

What kind of reducer is that? Further more are they pressure rated?

Those fittings are for water drains etc and are probably not rated for pressure. Closest hardware store here sells same stuff.
But I guess it's ok for combustion.

Nice looking cannon.

He showed this cannon earlier this week before these mods...here http://www.spudfiles.com/forums/my-seco ... 13869.html and has already been subjected to the third degree on the fittings.

So Grizzly, have you been able to fire this thing after your modifications? Did you notice any performance increase with the longer barrel and meter design??

Actually yes ! it is better because I don't need any spays or something but it is heavier so that's a bad thing. I'm apologize but I haven't time to shoot with some potatoes or something ! I let you know if there will be any increases ... Yes I am able to shoot !
