Zern, I scribed the design on from a drawing made from a photo. I used a cronite pantograph to do the reduction. An acetone transfer from a photocopied drawing would be fine also, many ways to skin a cat, so to say.
Thanks for the comments Dave
At the stage it's in here I probably have two hours design and two hours engraving into it.
I am using the new 70 degree Lindsay bulino tool template to sharpen the graver, and using it in a ordinary tool handle without power.
