As I understand it, there are a couple different ways to carve riser woods. You can use hand tools, a dremel, a high speed engraver, cnc router, or combination.
But how in the world do you make a contrasting part of the carving appear to overlap other woods? I attached a couple pics from the Blacktail bows site. Do you have to laminate an additional piece of wood to the side of the riser and carve it all away except for the outline that you want remaining?
I'd love to learn to do this on future bows, but feel like I'm missing an important step visualizing to how to get from A to B.
