Half Block milling

[Wubby]

I want to Half block my 2k r/f cocker and i was wondering if anyone had the measurments of the body and the back block. I was also wondering what bolt i have to use and exactly how the marker is cocked. (what i was thinking is that the pull pin goes into the valve and pulls it back when the gun is cocked but correct me if i am wrong)

Thanks..

We have a Fireball Mountain and it doesn't have a back block. There is a guide groove milled to the back of the body along the pump arm line. The pump arm is short and goes to a "carrier". The carrier goes between the body and the bolt. A pin goes through the top and through the bolt, the carrier, and straight down into the hammer. The FBM site may have a phots of the setup. I'm having FTP problems right now, or I'd post a photo of the one I have for you. It's an interesting and speedy setup.

There is a site with all the measurements and details of what to do to it. I forget what the site name is off the top of my head. I will look around and see what I can come up with.
