Thanks Glen.....I have the Keller manual but it doesn't go into much detail.
Basically say's cut one board with the dovetail bit, lay that board over the second board laid flat face up, scribe the dovetails onto the second board. Then project these lines to the end of the board, locate the dovetail template on the board to remove the waste in two passes, moving the template in-between cuts. Keeping the depth of the bit the same.
I did e-mail Mr. Keller a few days ago asking for a bit more of an explanation, just haven't heard back yet. I'll probably give him a call when I get a few days off if I don't hear back from him. I really appreciate everyones help here, I'm glad I joined.
