The video shows how a toothed pulley was cast and then machined.
The pulley is to go on my spin indexer which will be connected with a toothed belt drive to an Arduino controlled stepper motor.
This will enable any number of divisions to be indexed at the touch of a button.
The electronics and Arduino sketch were devised by Gary liming and can be seen here. http://liming.org/millindex/
Details were also given in Model Engineers workshop issue 249.
