Hi Eric - IMO it would be a lot safer, for you and the planer, to just make a simple planning jig for your router and use a large dado cleanout bit. The axis of rotation for the cutter would then be perpendicular to the board and should be much cleaner and less dramatic. :smile:Well, when making another cross grain cutting board I ran the cross grain through my planer. It was done very little at at time, just so I could hear the getting hit. The edges were hit up very little, but I'll be routing those. So it worked pretty good. Does anyone out there think I'm crazy for doing that?
