Machining Spoked wheels

[boiss]

Hadn't thought of spinning the cutter, I guess it could also be a 180 degree form to do back and front at the same time. Only problem are the ends and roots of the spokes, because of the inside curve at the end they can't really be filed except at 90 degrees.
How about the Loco wheels which get so fine at the centre?
I had some wheel castings for a gauge 1 loco many years ago and they were pretty rough.
