I am making something to hold an iced tea decanter. It is basically a 10" diameter plate, 1.5" thick. The center portion will be reduced to 0.5", with a 0.25" rim around. Some maybe a really short bowl rather than a plate. That is a lot of wood to remove. I frequently use a forstner bit to remove wood before I take a gouge to the inside of a bowl; perhaps there is something similar here? Any ideas? Maybe something with a router? Anyone lend me a 9.5" forstner bit?
