	Cool demonstration on how a cut-rifled barrel is made. (You need to *Login* or *Register* to view media files and links)

	Very nice, except that the rifling cutter should only be raised once per revolution of the barrel, instead of being raised for every cutter pass. As shown the groove diameter would not be equidistantly round. Not all rifling box cutter heads use a bump wedge, most use a screw socket arrangement to raise the cutter via like Pratt & Whitney Sine Bar Riflers.

	The more ballistic research I do convinces me all the more Schoyen, Pope and Peterson had it right over 100 years ago.

	That's groovy. Now, how about an animation of a early deep hole gun drill and drilling machine? To specific for the internet, I suspect. Early, I mean the first ones used. Joe.

	And to think that Harry Pope cut a bore by hand with the machine he made! And guaranteed a 2" group @ 200yds for an extra $10.00 Interesting - Thanks for posting

	It really just a mechanization of the way original muzzle loaders were rifled. This sure beats making about 100 passes for each groove, shimming in between with paper or wheat stalks or the like. One thing still remains the same. A cut rifled barrel will have an odd number of lands and grooves. There always has to be a land opposite the cutter to support it. Dick (see. I build more than just TD's)

	Joe, that's way too much trouble using the method we learned at Williamsburg and my tutors. I would love to see what you've described looks like. Might be the machine age has provided a bunch of new stuff than us olde f.....guys used. As I think about it that double backing would prove extremely difficult to use with a hand cranked wheel and wooden guide. So enlighten me. I'm always willing to learn new stuff. Dick

	Don't think we're on the same trail, Dick You will find old muzzle loading rifles with four six and eight groove rifling. All even numbers cut by hand. Odd number of lands not required for cut rifling. New cut rifle barrels the same thing, odd number lands , not necessary. Just happen to have Vickery's book handy. Wasn't my idea Dick, they been doing it both ways for over a hundred? Hundreds of years? Joe.

	Did not know about the odd and even grooves. Just finished a six groove .32 caliber barrel, left hand, gain twist with .040" land width. Rifling machine looks like the old fashioned wooden cylinder, except made from PVC pipe. May be the rifle to shoot consistent one minute groups. Looked promising when fire forming cases. Know that is old hat for some, but never done it consistently. Chuck

	That's neat Chuck! Groovy. Can you post some pictures? I'd like to see all of it. Did you drill and ream the blank also? Joe.
