Hi Greg, note that the Forrest Dado stack doesn't always have holes drilled for drive pins like yours does unless you order it as an option. The laws of physics do not know if you have a regular dado stack on the arbor or an adjustable groover without drive holes on the arbor with respect to wanting to spin the nut off. Equal care must be taken in each situation.
I was looking at Radial Arm Saws a little while ago and found a big mainland European manufacturer of RASs that actually ships the Whitehill 300mm adjustable groovers with their RASs. That's a pretty big groover set!
