Upgrade no 3, yep have rebuild my rifling cutter assembly with a steel sprocket, "13 teeth", and set in bearings for smoother cutting, a steel shaft for the rifling rod to hold the cutter head. At the mo I`m rifling a .50cal barrel as a pop in for my .45 Hawken, it`s 21" long as could only get a 30" gun drill, so will have to do. Giving it a 1-48" twist and 8 groves cut rifling for round ball shooting. When finished will lead lap with diamond paste for a smooth bore.
, Finally got it right, I think!!
