There is a small burr on one of the knives on my Jet 6” jointer. It is leaving a very small 1/16 – 1/32” mark in the wood I plane with it.

What is the proper way to remove this burr?

It depends on whether the knives are leaving a ridge or a groove on the board.

If it’s a groove (depression) in the wood, you will need to resharpen all the blades.

If it’s a ridge (raised line) and if your blades are still sharp you can loosen one blade and move it the width of the ridge and that way the nick in each blade will be slightly mismatched and your ridge will disappear.

If you are not able to move the blade left or right at all, you will need to resharpen all the blades to remove the damage.

Fine Woodworking shows a technique to hone your jointer knives in place. It probably wouldn’t remove a chip, but it would clean up a raised burr. You may need to be a member to access the article.
I have used this method on my Jet jointer, and it works well.

It is a raised rid I will try moving the cutter over slightly.

Have your say...
