G'day everyone,

Today I will be converting the $200 dividing head to be driven by a CNC stepper motor. A limitation with the standard dividing plates is that not every gear can be cut. I need to cut a 57 tooth gear for an upcoming project and this dividing head can not cut a 57 tooth gear.

I could cut a 57 hole dividing plate, but I have been wanting to convert this to CNC for a long time, and this has given me a great excuse to do so. I have made a few CNC machines in the past, and it is always a lot of fun to do.

In this first video I will be making a mount that will allow me to attach the stepper motor to the drive shaft. I hope you enjoy the video.
