This is not Tom, but this is his gun:
The simplest machine is one that uses another rifle barrel to control the cutting head. This is a very old method. Instead of having a grooved or ribbed rifling guide, a barrel is sued, with a cast slug to generate the twist. I have rifled a barrel this way, and it works.
Apart from single point cut rifling, buttoning and hammer forging, there is another method - broaching. The broach is pushed or pulled through the bore, and all grooves are cut in one pass. The method is simple, but making the broach is more complicated.
Copied these from another thread, just cuz its cool...

"...I'll buy one..." That'll likely cost in 5 figures or more. You can't use a regular lathe for precise deep hole drilling either.
"...available at Chapters Book Store..." They don't sell anything firearm related.
