X/Y zero point for wide bit

1

I am using a 3/8 wide mortise bit to cut a 3" diameter pocket hole in the back side of my 1" thick oak clock face for a quartz movement. Do I zero my x/y to the outer cutting edge of the bit or to the center of the bit? I’m having poor luck with getting the hole centered to my piece.

You need to center it off the center of the bit. The easiest way for you to do that would be slip in a vbit and center it to the corner then raise the z axes without moving anything else and change the bits out. Then zero your z axes. The fine point on the vbit makes it much easier to center it over the corner.

Thanks, Wayne. I’ll be carving tomorrow and will try that.
