Bue, yes.
I Cnc the profile of the riser then add the shaping by hand. This allows me to alter grips if I so choose. Then the shelf is cut to exactly .007” past center.
I also use my Cnc to profile the limbs, cut the limb bolt alignment holes, and cut the limb butts. Makes for a quick process after glue up. It’s taken me a years worth of headaches to get here, but I pretty well have my process down.
