I have the Rigid 13 inch planer and I like making end-grain cutting boards. My problem is, after milling is done and all the boards are beautiful and done with the first glue up, I plane again to flatten from inconsistency in wood height from clamping and after I make my cross cuts I notice my boards have gaps between because the planer left “birdbath” cups and divots throughout my board. Is this a common problem?

Do you have any pictures? I am uncertain which side the cupping it on.

“cupping” may not be the best word as it is easily associated with board warp. basically when i cross cut and go to fit the boards together there are some pretty extreme gaps especially in the center. but its not consistent through the board. I have no pictures at present

Mike – are you actually running a finished glued up end grain board through your planer ?

If you are talking about scalloping or many shallow troughs left behind on the workpiece, then I think it is just a result of trying to plane end grain with straight knives. The stars have to align for that to go right. Some people get away with it, but only under certain conditions.
- brand new sharp knives
-or better yet, helical head
-waxed planer be
-extremely light cuts (remove next to nothing per pass)

I think a drum sander or ROS is a better tool for the job.

No John, this is planing the edge grain before the crosscut glue up. i learned my lesson planing end grain

If your plane is leaving a scooped or scalloped surface it might be because one of the blades protrudes a little more than the other. Also I think two knife planers are worse about this than 3 knife models.

Stil,it should be so mistaken jet you can’t see them in the joint. Pics will help.
