I like to play blackjack. I'm not addicted to gambling, I'm addicted to sitting in a semi-circle.

I can imagine. When the 2 inch t shirt tank was ready, I took it to the auto shop who donated the chamber tank to show them. They wanted to hear it so we filled it in the shop and made casual bets on whether it could move an impact wrench on the floor 3 feet away with no barrel.

It was LOUD :shock: . It also tossed the air impact wrench another 6 feet down the floor.

Can't wait to get my 3 inch 200 PSI one finished. :D

so it haven't fired anything yet...?

getting to this point is relatively easy - real problems start when you have to add a feeding mechanism


if it going to use BFB or a simple T?

I have fired it, but just muzzle loaded bb's so nothing special. Tomorrow I'll start work on the true semi/full auto ammo feed.

I think I'm just going to use the compression fittings I have an use a compression T to add the the "for now" gravity fed mag. I promise you I'll get a jam but we all have to start from the bottom.

That's not how it works. Others have started from the bottom and shared their experiences, in such a manner that those who follow can start higher up ;)

Haha you make a fair point. as far as making a nice secure ammo feed, I think a male T with compression fittings will be my best best. Should stop it from moving around on me.

Expect some nice results tomorrow.

(Way to jinx yourself Mitcho:D)
