If you’re new to woodworking then you’ve probably never even considered the pros and cons of running end-grain through a planer.  In fact, often times new woodworkers attempt this feat without ever thinking about it at all.  It usually goes something like this… They decide to make a cutting board.  They read end-grain is the best.  They spend a lot of time slicing the board, gluing it up, etc.  Then they sand, sand, sand, and sand some more.  Then they slice the board and glue the end grain up, only to realize their sanding wasn’t perfect, there are gaps everywhere!!  And so they scrap the whole board.  Off to Rockler Woodworking to buy a planer (in my case the DeWalt DW735X!).

Honestly, that’s not too far from my story.  Fortunately for me I was taught about end-grain dangers from my shop teacher some 30 years ago in high school.  For many, the next step that follows for most people is to run the finished cutting board through the planer end-grain up, in many cases to disastrous results!

End-Grain Cutting Boards through the Planer

The most common end-grain item that a new woodworker is most likely to attempt to run through the planer is an end-grain cutting board.  It’s an extremely common new woodworker project and without any thought behind it (and why? it seems perfectly reasonable on the surface) it goes right into the planer; end-grain up.

Why is it End-Grain through the Planer a Bad Idea?

end-grain through the planer 0001Wood is fibrous.  The fibers are what make up the grain of the board.  End-grain is basically where all of the fibers end.  Think of the end of a board like the end of a brush with the bristles sticking up.  Have you ever tried sanding the end-grain in your projects?  Have you notice how much more difficult it is to get end-grain smooth?  This is the same reason there are different blades for rip cutting and cross cutting.  Different orientations of the grain behave differently.  Cutting end-grain is much tougher on your blades. If you send end-grain through the planer it stands a very likely chance of the board fracturing and your planer ejecting the board and very high materials.  This is an extremely dangerous situation that you do no want to be around when it goes off.

My Personal Story with End-Grain through the Planer

A few years ago I was watching this guy on YouTube called “mtmwood” run cutting board after cutting board through his planer.  So I thought “If he can do it, then so can I!”  I proceeded to run my just finished end-grain board through the planer.  I used rails on the front and back, just like he does.  Within seconds into the cut I hear very loud banging and popping as my cutting board is ejected in 5 separate pieces from the planer.  My planer continued to buck like a bronco afterwards until I could shut it off.  A new set of blades later and lot of pride lost I was back in business.

But They Do it All the Time on YouTube

Yes they do!  And there’s also some disaster videos of it on YouTube too.  Having seen those videos and experiencing it myself, I have to say “Just Don’t!”  It’s not worth the risk.  Some people are luckier than others.  You never know when your luck will run out.  Get a drum sander.  That’s the safe way.

    I run endgrain through the planer all the time. Never heard of it being a problem and I don’t plan to stop. I don’t believe you.

    It is perfectly safe as long as you know what you’re doing. If you don’t, then you should definitely stay away from it. One method is to attach a side grain piece of sacrificial scrap to the leading and trailing edges of the end grain boards going through the planer. Also, if it isn’t already obvious, be sure to make very shallow passes.

    I looked at the video and I think it is miss-named as an end grain chess board. It is made of strips of wood with the end grain on the glued side not the visible side. In cooking terms it is a slicing board not a chopping board.
