While I just ordered another batch of CNC mounts, I am experimenting with how to make them more efficiently at home. Here are two more methods, I’ll spare the machinist details.

Lathe is a Wright Brothers era machine that was originally pedal powered!

  1. Turn mount in lathe, 4 jaw chuck (mount spins around, single point cutter makes the grooves)
  2. Run lathe like a horizontal milling machine (cutting tool spins around, mount held still)

2 bolt mount!
