Topic tags/keywords: r4330 wide panel planing planer high spot planer

Hi Folks, I’m having some issues with my R4330 planer. I’ve been making a lot of end grain cutting boards using the edge grain glue up, then slicing into endgrain rows. Of course I join and plane all the long grain boards, ensure my glue joints are absolutely aligned, and use cauls to keep The Whole thing flat during glue up. Following glue up I scrape all the dried glue off and then plane it flat, I only have a 6” jointer. I’ve not had any issues until the last few weeks. When I plane these wide glue ups I am getting a high spot around the middle 1/3 of the glue up on both sides? It seems to me as if a high spot on one side of the panel would be a low spot on the other. I’ve tried taking very small passes, 1/64-1/128” to try to flatten one side but fail. I have changed to new blades recently but it was having the same effect with the old blades too. While installing the new blades I cleaned the cutter head, feed rollers, and anything else I could get to.

The high spot is about 1/32. A picture attached shows the difference in flatness across the face. Of course this 1/32” in each row running the length of a 24” end grain cutting board is causing gaps and cracks during glue up.

Apologies for the long post but trying to eliminate questions.

While portable planers deliver a high quality
finish in my experience heavier cast iron
planers deliver a more consistent thickness.

You can make a sanding board with a piece
of belt sander paper glued to a flat board
and joint the parts flat after cutting them
up and prior to gluing. A sharp hand plane
would work too but takes some work to
get the hang of it.

I disassembled the planer, removed the blades I just installed and reinstalled them . Cleaned the feed rollers, adjusted the infeed and out feed tables again. Seems to be a little better. Using the micrometer I’m about .003-.005 out across a 12” piece of stock. That’s better than it was.
