I'm going to make a few instrument dials, including a sundial. These are all items with numbers, and various circles large and small engraved on the face. They range in size from about six inches (roughly 15 cm)in diameter up to roughly 10 inches (about 20 cm) in diameter.
I want to make these in brass, and it seems that the easiest way to engrave circles would be
to chuck the plates up in my lathe, use the right type of cutting bit in the tool holder and then
slowly revolve the head by hand to engrave circles.
Here's the question: can anyone advise me about what shape works best for my
cutting bit? What type of profile should I grind my bit to in order to get
the best and clearest lines?
Has anyone done this? Or can someone perhaps recommend and Internet page or a book that shows
how it is done?
