Start at the first page and look at the whole thing. It starts out with CAD pics of it and shows photos of a .25 cal single shot PCP he built, also. When you get to the photos of the lever action , you can't help but want one. Reminds me of a Marlin lever action. Check out the rotating wheel safety on it. Like a scrolling wheel on a mouse. It's gorgeous. I've been looking at that one for a while, and don't know why I'm just now getting around to mentioning it here.
