I have a piece of hardwood (wenge) in which I need to cut 2 keyhole slots. The strip is 1" thick, 2" wide and 15" long. I'm using my router table and a slot cutting bit. I'm ok cutting the first slot on the back of the right side but not sure how to cut the slot on the left side. If I just move my Incra fence to the right, it leaves very little board left of the bit to control it. If I turn the board around, of course then the top of the slot is facing the bit and not the bottom. Can I safely just leave the original set up and cut the second slot from the other side of the bit and pull it toward me. It'll only be 3/8" deep or less and only about 3/4" long?
