Hi,
I have a Jet 6” jointer with a helical head. I recently rotated the cutters for the 1st time. Now I get a ridge when I joint something. It appears that some of the cutters are too low. It does it on the fence side. I have tried swapping cutters from other spots on the head and it still does it. It never did this before. It has been a wonderful machine til now.
Thanks
Skidiot

You need to make sure the mating surfaces are absolutely clean and torque the screws to the correct tightness.

Yep, the cleaning of the seats and the torque (45 in. lbs. for mine) is important. For me, even after I did that I still get light lines, they come off with 2 passe (literally) of the ROS. Funny thing, I did this (cleaning/torque) on the jointer and eliminated the lines, but it didn’t work that way on the planer, it leaves those little ridges. Bummer, since it sees the wood last.

Mine also has very, very light lines that can be removed with an ROS in about two passes. Started when I went to the second edge a couple years ago.
I was very careful to clean and blow out every bit of dust and contamination, and clean the back of the cutter before re-seating the cutter. Torque was done by me, but I must admit, taking them off, the tightness was all over the place.

It’s not a big deal considering I put some cherry burl, quilted and flamed through the planer a few days ago to make a wooden pickguard, running it down to 7MM thick, and I got zero tearout…

If the cutters are flying around your shop, you might want to tighten them a bit more.

I would clean the head with compressed air BEFORE removing the blades. That way you are not knocking as much junk into them.
