Hi Bruce look on line for INTERNET ARCHIVES they have popular mechanics PLUS heaps more that can be downloaded.

You don’t need a complicated power supply – just one that is safe. Look, you are going to have water running over your work and the electrode, and when your skin gets wet its resistance drops and
