This is just a shelf that goes on top of friends dog crate. I chamfered with Felder 150 mm shear rebate head at 45 deg and got a chip out in one spot. In this particular case, the shelf was elevated by a piece of plywood so the wood was backed up even though there is a gap in the table around the cutter.
Is there a way to minimize chances of this happening, like putting a tape on the surface being milled? I know it is risky to do it on the end grain. Perhaps, I should have done it in couple of passes.
