Jack plane. You just make the marks and join em up. Quicker than the alternative (unless you have several to do) - a curved jig, either vertical against the spindle, or horizontal over the planer.

I did it by hand , the main problem was its not the same all the way around so i couldnt see how to machine it .

If the flat needs to be paralell to the inside, then I run mine through the thicknesser on a jig prior to assembley.

Spindle, ring fence.
Trouble is Jason, you have to stand near it.

I cant see how machining it would work as the cill changes shape so the bevel needs to change as you go around but still stay the same on the thickness . The only way to do it is by hand as far as i can see .

I cant see how it can be machined on a spindle as the bevel isnt constant. May be possible on a cnc machine.

Those 6 siders I just done had varying thicknesses at the front edge. Warned the customer about it but they were happy to go with it.
If I didnt know there was a difference, I doubt anyone would even notice.
If they do specify a continuous thickness around the front edge, I run them through the thicknesser, then mark at the joints the thickness I want to achieve, then go to town with the belt sander. Never takes too long

crikey, thats abit posh.
Usually widen the gap between the fences on a router and use the corners as contact points.
