What is it.. for the love of $DIETY .. I have tried 1/2, 3/4, 5/8, 7/8...

7/8 comes close.. but I end up with this.. Using Fusion 360 to design the cutout. I know, I could probably have done it manually with 4 strips of wood by now, but that is not the point.. I have a CNC for a reason (and that reason is fun )

Bump.. anyone? Someone has to know.. I suppose I could call Jessem... but someone has to know.

Try it in metric

Try putting a compass or divider in the center of the hole and measure to the flat just before the curve. That should give you the radius (theoretically).

Take a look at this manual it says the radius is 3/4.

Try a piece of tape on the 3/4. You may need to do this the old fashion way.
