Homebrew PCBs

Bertho,

I have a full machine shop including a Gingery shaper which can cut these
tick marks. But my goal is to invent a new way to make a graduated dial.
Being able to etch a dial would be an advancement.

Rick

If you do not have a rotary table it is simple to make one since there is
zero force on the subject.  A 100 tooth gear will give you accurate
indexing.

No art work is needed for the critical lines, either optical projection or a
laser line source.
