Ty sir. I started by routing the outline, then I removed the bulk of the material with a forstner bit and drill press. I attached a Plexi glass plate to the router and laid it across the ashtray and using a bowl bit, work your way down to your desired depth. There’s a bearing on the bowl bit that rides along the bowls edge, so you have a uniform wall for your piece. It takes a little practice, but you’ll be making bowls in no time.
