here are some vids like what I was thinking on
I want to build a Rifiling machine for My M6 Build any one want to help or give me some input or Ideas ?? If you check out my project page my m6 scout build I got a few mor pics so basicly I need a .22 button a cylinder set up like above pic dont have to be wood and a frame to hold it in any takers on helping me on this quest LoL
The machine in the video uses a cutter, not a button. It cuts one groove at a time, and takes several passes per shim, and several shims per groove. (He is cutting as much as he can with one shim, then indexing for the next groove. When he has cut all the grooves with that shim, he adds another, then starts all over with the process till he gets them all the correct depth.)
The setup he is using is called a sine bar rifling machine. The bar on the left can be set for various rifling twists by moving the end to a different position, (if he was wanting a gain-twist, the sine bar would have to be bent in a curve).
This is a much more convenient setup than button rifling, but more time consuming. Button rifling is used in mass production, and takes a lot more overhead.
For one barrel, another barrel could be used as a guide which would eliminate the necessity of building a machine. Ebay has barrels of all kinds.
As to the cutter, it is just a broach, shaped in a slight hook. They can be made from tool steel, like 0-2, or made out of a piece of old file that has been annealed, shaped, and rehardened.
A source of good information on this is Foxfire book #5.
This website sells a book and DVD on how to make a rifling bench similar to the one posted first in this thread:

Here's a page with a lot of general info on barrel rifling:

Here is yet another book on rifling a barrel:
Rifling Machines & Methods
Here's a YouTube copy of a video that was put out by Colonial Williamsburg in the past on how a flintlock rifle was made back "in the day". It shows a lot about barrel making and rifling.:
Finally, here's a link where you can download a PDF of the book "Advanced Gunsmithing" by W. F. Vicery that has a lot of info about rifling barrels.:
