Watch: Homemade Barrel Rifling Machine
Russ Chastain 04.17.17
So you want to cut rifling into a gun barrel at home, eh? Well, fear not. This fellow shows how he created a homemade machine to accomplish that, using common parts including Sawzall blades, an electric drill, and bearings and housing from a bicycle sprocket, among other things. Oh, and some rolling papers.
The drill is used to force the cutting tool through the barrel, using a simple twist rate guide that is much easier to make than you might assume. The bicycle parts allow the drill rod to turn at a different rate of speed than the guide. And bits of Sawzall blade are used to do the actual cutting. The cigarette papers are used as shims to control the depth of each cut.
The work looks tedious (and I’m sure it is), but the end result is sure going to beat a smoothbore. And he says the rifling process took only 30 minutes!
Not bad, Mr. Westwood. Not bad at all.
