How to power carve a bowl

He’s been carving bowls this way for 15 years, and has refined his technique as well as his forms.
I carved my first bowl 15 years ago. I had cutoffs from making furniture that were too small for furniture yet too big to throw away. I decided to make them into something useful and perhaps learn a new skill. The tools at hand were a drill press, a bandsaw, a 4-in. grinder with a sanding disk, a 12-in. disk sander, a random-orbit sander, and a few files and rasps. The process was long and tedious but I was pleased with the result, and I started looking for better tools to make the carving go faster. Over time, I have tried many tools and brands, settling on a kit of tools and streamlined techniques that make power carving efficient and fun.
When I pull out a chunk of wood to carve, I have an idea in mind about how I want the bowl to look. If I make a sketch, it’s just a suggestion; I let the wood’s grain and any defects play a role in the final form. Except at the initial sawing stage, I don’t often draw on the blank itself. I prefer to freehand the shape as I’m carving. But I’ll stop from time to time and look at the shape as it is emerging, and if I see something I want to change I’ll sometimes draw the new shape on the bowl with a pencil or piece of chalk and carve to it.
Rough shape the bowl blank
On the top of the blank (in this case a piece of kiln-dried mesquite) I draw freehand lines showing the outside shape of the bowl and the inside lip of the hollow. I cut the outside shape at the bandsaw and then use a drill press to remove waste from the inside. I use any drill bit that will efficiently remove wood. In this case, because mesquite drills easily, I used a large Forstner bit and the hollowing went very quickly. On harder, denser woods or when drilling into end grain, I’ll use smaller brad-point bits. I overlap the drill holes but sometimes there is a pinnacle left which is too small to drill. In that case I either grind it away or just break it off. I’m not concerned with making a smooth, flat bottom, since it will be carved and rounded later. Don’t get too close to the inside lip or drill too deep into the blank; leave plenty of wood to carve.
