I decided that since I was building from wood, I should take extra grounding precautions -- there's on metal frame to connect everything together. The shell of the toggle switch, the motor bracket, the motor controller's heat sink, and the bandsaw itself are all wired together to earth ground from the power cord. This shows the bandsaw ground wire -- it's connected (via a nut cinched against the bolt head) to one of the "set screws" that push against the mounting tubes to tighten it up.
