Rifling the Model Armstrong RML
The HSS cutter is mounted in a tight 3mm wide slot in 16mm silver steel. The 4 mm cap screw pushes the cutter up by 0.2mm per full turn of the screw.
The following video shows an air cut of the rifling cutter in the CNC rotary table on the CNC mill table. Then some actual cuts in a 1:10 scale cannon barrel. This barrel was a reject, and was used to practice the rifling cuts.

Very nice! It looks like your cutters are cutting very well. That setup is way better than the lathe contraption I came up with… sometimes I wish I had CNC in my shop.
