This might just be a problem with 1/2 inch birch plywood. I finally got the Mini secured well enough to try it - which is a story in itself. I drilled my very first hole with my Kreg Mini and on the surface it looked fine. But I turned the board over and the layers of laminate were separated. It was split just like as if you had driven a nail there. Is there any way, other than not using plywood to stop this?
