More Shaper Tricks on a CNC Mill: Cutting Splines

I continue to be amazed, entertained, and intrigued when I see Simpson36′s work with his fancy 4th axis rig on his scratch-built mill. His latest is showing how to cut splines and other fairly exotic shapes using a lathe tool lashed to the side of the mill head:

Something to note: this is a very cool capability, but don’t try to attach the tool to the spindle directly. You don’t want to be bashing your spindle bearings on each stroke. Build a holder that affixes to the side of the head.
