So I just completed the glue-up of my first end-grain cutting board and I was just about to put it through the planer when I saw a thread saying that someone did it and it was a disaster. He didn’t explain why or if it was something he did wrong. The bottom of my cutting board is perfectly flat but there is about a 1/64” difference in the top. Is it a mistake to put it through the planer? If so, what tool should I use? The board is made of walnut, cherry and maple.

Any input helps. Thanks!

Cole, dont know why there would be a problem running it through a surface planer but if you are worried about that, use a belt sander if you have one. I routinely use a 3×18 or 3×24 sander to flatten panels. you’re going to be sanding any way to get it ready for finish so running a belt overit at about 100 grit isnt going to hurt. Just remember to keep the sander moving. Dont let it stop too long in any one spot. Start by sanding diagonally across the surface one way then diagonally the other direction, then straight down grain. It wont take long to flatten the piece.

I use a belt sander. Like AJ said, just keep it moving.

A planer will tend to grab end grain and shoot chunks of your cutting board through the outfeed side. I’ve never done it, but I’ve read several accounts of people who have tried.

Hand plane, drum sander, belt sander, router sled…

Given the varied experiences of people posted on this site and others, I’d vote against it. It’s one of those things that could work out fine, or could go very badly. Doesn’t take much time to do it the other, safer ways. Someone posted a setup on here that had two small bench-top tables, both level with a sander between, and a stop block on one end to keep the board from taking off.

Wide belt sander is the way to go if you have access to one. I’ve made a couple end grain cutting surfaces this year and I don’t know how I would have done it without my local shop’s help. They charged me a dollar a minute and it took all of 3 minutes through the wide belt sander.

Ok thanks! Ive never really considered sanding to be a method of flattening or removal but it does make a lot of sense. I will try that as soon as i get into my shop later.

I was going to mention wide belt sander too as Joe did. I have the Delta model and use it for larger pieces. But not everyone has one or has access to one. I also agree that if you have access to a local shop, the cost is minimal. Thats what I do for resawing pieces that are taller than 10” or so. And my local lumber supplier charges next to nothing to cut stuff for me. If you dont have a belt sander, well now, this project may well be the excuse you genuinely need to just go out and buy yourself a new toy. After all, you can justify the expense to the powers that be at home, if you have to justify it at all. I’m just sayin.

If your bottom is flat then I agree with Joekwan and AJLastra,, but as AJL says lots of people don’t have one or access to one. I do and it’s perfect for something like that. I’ll go with the consensus of a constant moving belt sander, did that way before I had my Delta X5.. I would definitely stay away from the planer with end grain.
