Cool Mini, Need Help

Unread postAuthor: LGM » Sat Feb 10, 2007 2:35 pm

Here is a mini that I threw together from the metal one I posted under "my favorite mini" from some stuff that I found. The pistol grip is from a small crossbow that the string came off of, I taped the peizo above where an arm would come up to fire the arrow so that it would depress the igniter. The chamber and barrel is hose clamped on, you can see the rest of it yourself. I need a way to seal off the back of the chamber when I fire it since now the cap that I was using can't fit between the chamber and grip. Before I mounted the gun on the grip I found out that MAPP gas is probably the best mini fuel that there is, it sounded like a high pumped BB gun going off and doubled the speed of the projectile.

C'mon, someone answer. I have since epoxied the peizo in and removed all duct tape. Also, to avoid getting my dad iritated, I made a silencer for it so now it actually sounds like silencers in the movies.

Use a rubber stopper/cork/wadded up paper anything you can shove in there.

I forgot to say, I also carved out the area below the end so I can screw on the cap.

its nice for a mini but id look around at other minis and mount it on to the grip .........otherwise pretty sweet........paint it black..... put some bondo on it so that you can form it to look like a regular pistol then amaze everyone when its not

Umm, jjk92, could you clarify what you mean by look ing around and mounting it on the grip?

Spudthug, the white thing above the trigger is a peizo that runs to the chamber. The cap at the back comes off to load butane in. Hope that clarifies it.
