[Shop-talk] cove (or 'dish') style cut on a piece of wood.

[Jimmie Mayfield]

Looks like I missed the original message.

I've never done this but here what I'd try:

1. Use a router with a carbide straight bit and a circle-cutting jig to 
cut concentric circles starting with the outer edge of the bowl and 
moving inward.  You'll need to figure out the depth for each successive 
circle depending on how steep you want the bowl to be.

2. Use a chisel or a forstner bit in your drill press to remove the 
centermost section (the piece that you screwed your circle jig into).  
At this point, you'll have a "step" bowl, similar to what a strip mine 
might look like.

3. To smooth out the steps, I'd use a 4 1/2" angle grinder and a flap 
grinding disc.  In fact, as I write this, I suspect you could make the 
entire bowl using just the angle grinder.  You can buy a sculpting disk 
for an angle grinder that has chain saw teeth.  Use that to shape the 
bowl and the flap disk to smooth the gouges.
