Edit: June 1, 2019

added photo showing to grind flat spots where the 3 mm allen set screw meet the shaft. (my first drill job I had issues with allens slipping, any tighter would have broken the sprocket. 15 minute job putting flat spots fixed that)

Edit: May 29, 2019

Added Control Box for Ardunio Nano Added Box Clamp with built-in Tie wrap holder Fixed nut hole being to large for the nuts

Edit: May 28, 2019

Added missing motor mount Head Added bearing used Added O-ring (used for belts)

Calibrate ESC before uploading the Drill code (or you may have motor running to slow at full speed)

ESC calibrate with Arduino code - ELECTRONOOBS

Drill code I used

Control Brushless Motor using Arduino

https://howtomechatronics.com/tutorials/arduino/arduino-brushless-motor-control-tutorial-esc-bldc/

middle pin on POT goes to A0 and if pot turns the wrong way (left for off) just swap the wires on outside two pins. also know with ESC if you turn power off with pot turned to high you have to turn the pot down to be able to start motor again (must be a ESC safety thing)
