Ok so I have heard a lot of people talk about making end grain cutting boards, and most of them have horror stories relating to disastrous results from running them through a planer. I myself have made no less than 14-15 end grain cutting boards and I ran every single one through my Delta portable thickness planer with very little issue. Of course the last edge that comes out will be “flaking” off but that could be solved by adding an extra piece of sacrificial stock during the second glue up which can be cut off later or simply trimming undesired material off the edge of the board (my method is the second one). I wonder if it is a matter of material choice, machine choice, or technique. All of my boards have been made from different combinations of maple, walnut, cherry, and purple heart. Like I said previously, I have an older portable Delta 12” planer and I have described my technique above.
Another question that I have is about the surface maintenance of the board. I finish all my boards with generous amounts of mineral oil. After rinsing the board after cleaning the grain raises slightly, do you all find this to be true as well? I have a theory that I haven’t tested yet which would be to wash the board under lightly running water (not submerging it), then let it dry and sand again and retreat (in much the same way that you would treat material when applying a water-based finish). Please share your thoughts on this.
