Add a Teacher Note to share how you incorporated it into your lesson.
Use a Vernier caliper (slide gauge) to measure the dimensions of the gears, chuck, motor and other components
The dimensions I got for mine are show
Step 2: Step 2 - the Drive Shaft
The drill I used had a drive shaft attached to a kind of head, this had an odd profile so I drew around it with and then scanned it into solid works. Once in solid works I used sketch points and spline tool to draw round the outline.
After this I saved it as an SLMD so I could use it on the CNC machine
Step 3: Step 3 - Cutting Part
To cut the odd shape for the head I used a CNC machine and the SLMD file
The other parts to hold the motor and the gears were made using a metal lathe
The end result looked similar to this
