Here I attempt a repair I haven't done before - making a small brass regulator pin in the watchmaker's lathe. Lathes are an important tool for the watchmaker or watch repairer, and learning to use them properly is a slow but rewarding process. The regulator pins time the watch by ensuring that the balance wheel vibrates the appropriate number of times per hour. I also demonstrate graver sharpening by hand, a procedure I am still trying to master.
