It certainly is a great feeling when that first one hits the floor after being fired.
Ill hopefully start working on it this week, i'm going to try not to use any tape on it at all

The only part I don't have at the moment is a decent blowgun to use for the trigger.
Darkside: yeah I am using copper pipe as the shells as then I know they're the same diameter as my barrel.
Maybe I will do some carving on the stock, would certainly give it a nice finishing touch.
