    Thank you Jonathan, that is excellent information, just what I need! Will take me a little time to fully digest but will be worth it.

    I didn't consider the flat spot at all. Wouldn't have been a disaster, but wouldn't have been correct either!
    I asume if I use an insert v bit (such as CNC V Groove Miter Fold & Signmaking Insert Router Bit by Amana Tool) then I could just use Z=d/(2*tan(a/2)) as there would be no flat spot?

    The radiused tip/ballnose cutter was also a great thought. I was only considering supporting v cutters but I think you have changed my mind.

    Thanks!
