I recently got the PC 4210 to make some HB Dovetail drawers. My problem came when I went to make the dado for the plywood bottom. On the front & back of the of drawer, the slots for the pins didn't line up, so I couldn't make a through dado. It wasn't off by much, but enough that if i had done a through dado, the slot for the dovetail would have been cut. Any Suggestion anyone might have I'm all ears.
