I just did an urn with Praying Hands and roses on the front. I do this in 2 passes. First pass with everything but the praying hands, roses and the inset where the reside hidden. I do this with the 1/32 bit on optimal to get
t detain on the very small roses. Then without removing the piece I run pass 2 with the hidden parts switched and there is a zero depth carved area over the hands and roses. I do this with the 1/16 bit on best. Ask Bud and I had a long discussion on how to put a carved out area in a shaped carved area. This is my solution with a couple advantages; the bottom of the second carved area is flat and you can use optional and the finer bit because the area is smaller.
