I'm currently working on an end grain maple cutting board, and I've reached the flattening stage. I plan to use a router with a flattening jig/sled, but I'm facing a challenge. Neither side of my cutting board is flat — it sits on a melamine surface that is flat, yet the board itself isn't laying flush or square against it. However, it doesn't rock at all. I'm planning to secure the board to the melamine, but I'm concerned: will the uneven underside affect my flattening process with the router? I'm using a powertec flattening bit. I burnt the board while cutting because I used the wrong blade, but it doesn't seem to be a huge issue right now.

When you're flattening your cutting board, try using hot glue and shims underneath. Start with the bowed face or whichever side has a cup shape facing down. You want to make that top face as close to the cutter's height as possible. Once you flatten that face, remove the shims, flip the board over, and flatten the other side. This method usually ensures parallel faces with minimal material loss. I've found that good hot glue does the trick, but side clamps can help if you need to apply more pressure. Good luck!
Hey, just a heads-up about your burning issue! Starting with a dull bit can cause burns, but it can also happen if you hold the router in one spot for too long. Either way, make sure your cutter is sharp, and don’t stay in one place too long during your cuts!
Exactly! A sharp cutter is key. It makes such a difference during the routing process and helps avoid those burns.
