A solution for blind internal keyways in long parts?

[Parlo]

Had to cut an internal keyway in a part too tall for my mill & too long for my lathe so I made this.

There is also a tool that uses a rotary cutter similar to a woodruff keyseat cutter without a shank that is contained in a bar that enters the hole to be keyed and is driven by a shaft the protrudes out the opposite end and can be driven by a drill press or other machine tool, it is fed by hand into the hole and makes the keyway in one pass.

@Parlo,

Your last couple videos have been using your CNC mill as a shaper.
You are really thinking outside the box.
Thanks for sharing your ideas.
