Here is the result:

Came out ok. *You can definitely see where the taper begins in the
flute (not a completely smooth transition). *This can probably be
fixed with a piece of sandpaper or just leaving it alone.


I think the source of the problem is the abrupt transition between the
flat surface and the wedge. A three-fluted bit /might/ (or might not)
help with the slight side "dwell" marks at the transition.

If I were trying to do this on the CNC, I think I'd radius the
transition rather than do it as two straight-line movements.

Morris,

HUGE improvement!! Thanks. The router climbs with greater ease now
and the end result is better. It is a much natural climb and the base
ouf the router doesnt slam to a hult when it hits the wedge.

Check out the result hereunder reply)

I might play with different radiuses

Thanks again!


Oh, I see what you ended up with. You hollow-ground the edge to
quicken the transition a bit. I thought you might be hanging up on
the opposite edge, the 45 degree away from the point, hence my
original post. Mea culpa.
