Doing some small rosettes for window trim on a CNC mill with a high speed spindle so flex of frame shouldn't be an issue. Tried it with a cheap cutter and some lumber yard wood and was pretty bad but proved out some things. Now wanting to do the final ones. Got a better carbide cutter and wondering what wood I should try. They will be painted and not wanting to spend more than I need to. No super fine details. Is poplar a good choice?
