Thinking of using a bit profile like this, but I'm not sure this is going to work.
One time I had to duplicate a highchair tray that had a similar inside edge.. I had a pin router set up so made a template and struck it to the bottom of the tray stock. I took out most of the material to final depth in the center , then changed the template to make the outer edge cut in multiple depth ( height of bit). I put a larger insert in the table around the bit so that the chips could be sucked down through the table. If you are going to make several of these it would pay to get a pin router set up for your table.Only problem I can see with it is that you will be cutting "blind". Your work piece will be on top of your bit, and you won't know for sure where the bit is. Consequently it would be difficult to cut to the edge of your bowl, without going thru that edge.
or start...If youre going to use a router table, you must use stop blocks. No way can you control the wood to stop where you think it should be.
It wouldn't take much of a modification to make a rectangular bowl with a scooping jig. Instead of rotating the workpiece, just make a series of passes along one edge, then at 90 degreesJust checking.... are you talking about a circular bowl? I had originally thought it would be a rectangle / wedge shape.
Circular bowl is a lathe job. Turn them out in minutes. That chair scooping jig will do it, but its very time consuming if youre talking about many items.
on the table...My concern is a bit that diameter would be very difficult to control either handheld or in a table.
I was picturing something like this.I feel it would be dangerous with that bit. You might want to research a chair scooping jig.
