Metal Casting at Home Part 64. Casting and Machining a Toothed Pulley.

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.
