    So are you wanting to build a rifling machine to make a 22 rifle or are you wanting a 22 barreled rifle? Here are some links you might be interested in that just might make a really accurate shooting barrel.

    Barrel liners
    http://www.brownells.com/gunsmith-to...prod10974.aspx

    4130 tube for installing the liners into
    4130 - Chromoly Round Tube 5/8 X .156 X 3' - $24.95 : Shapiro Supply, Alloy steel, Steel, Aluminum, Stainless, Aluminum Diamond Plate, Metal Suppliers

    The 5/8" x .156 wall thickness will give you an inside diameter of .313" and the 5/16" barrel liners would be around .3125. Should fit but would probably need to be emery clothed to make the clearance fit just right.

    The 22 rimfire cartridge needs a 1-16" or 1-20" rifling twist rate. I question if you'd be able to get that fast of a twist out of a rifling log like you have pictured. Would probably need sine bar rifling machine using rack and pinion gears.

    I'm building a rifling tool for a black powder barrel out of a 4 foot piece of 3" PVC pipe and a 1 foot log sliding inside of the pipe. I've got about 50 3/8" metal dowels stuck through from the outside of the pipe circling around a 1-48" twist, and the wood log that has been turned down to fit snuggly has a corresponding groove cut into it to follow the dowels coming in from the outside. I'm not done with it yet and am not sure how well it will work. But this may be an idea for you.

    Illegal, maybe, maybe not?

    It is only illegal to build or own a machine gun if you do not have the proper permits. I have a friend who builds full automatic guns and suppressors (silencers). He is legal and has all the required permits. From what I understand the permits are not cheap, but can be obtained by anyone who passes the background checks. It is legal for anyone to shoot the guns in full automatic mode with a silencer provided the permit holder is present and supervising the activity. You are right about going to jail for this sort of thing without the permits however.

    In the video he made he asked his buddy if it was legal, He replied "I don't know but it sure is fun." He also kept showing Bill Holmes' book about how to build a machine gun. In his book Bill clearly advised his readers about the law regarding the build. It's a great book by an amazingly talented guy, but I felt like maybe the OP thought that because there was a how to book that it must be legal. Don't really know why I commented on the whole deal. Just answering his question I guess. I didn't know it was going to be gone when I set out to post. Hope he is O.K. over this slip up. GP

    Jamman; not heard how the project progresses.
    I found this researching Harry Pope, barrel maker extraordinaire. This is not to dissuade but inspire you. It describes the rifling cutter described earlier. This excerpts an article printed in 1934. San Diego Schutzenguilde
    " To rifle out the inside of a .22-caliber barrel takes about seven hours. The cutter is fitted with a wedge and screwhead so the feed, or depth it cuts, can be varied from time to time. The steel shaving removed from the grooves at first is about l/5000th of an inch thick. Later, when the end of the work is near and there is danger of cutting too far, less than 1/40,000 of an inch is removed during a "pass." It takes about 120 passes to cut each of the eight grooves within the barrel."
