BB gun finally getting built!

Unread postAuthor: Mitchza89 » Wed Sep 12, 2007 10:44 pm

G'day guys, how are we all?

I've finally gotten off my backside and the gun is getting build now. I know...It's about time!

I've found a piece of 15mm copper tipe which I've polished up to make the chamber. It's a little knocked around and abit out of shape but it's good enough. What do you expect, I found it!

I got my shock pump in the mail yesturday. I was a total lemon. Luckerly the bloke I bought it from is giving me a full refund and I get to keep the pump. I'll probably fix it but I'd rather buy a new one with the money I got refunded back.

If anyone has any idea's to make this any better, give me a buzz.

How was it a lemon? I've had mine for years and the only thing I ever had to do was change the o-rings on the piston head.

The piston had been cracked and pretty poorly repaired. It's just a cheap pump. Most of it is plastic. Best thing is, The money that I got given back, is the exact price of an all metal fox shock pump so I'm happy.

Sounds like you won in the long run with that one though!
How long is the 15mm copper? Would you perhaps mind posting up a diagram of the gun so we can "evaluate the situation"? :P
Sounds good though :D

Well guys, looks like the gun is nearly done. The barrel is epoxied into the end cap for the compression fitting and I'm getting the rest of the parts hopefully this weekend. I'm hoping this gun will turn a few heads :D.

Yeti, would ya rather see a pic of it half done or it when its fully done in a few days time?
