Hello all,

My name is Chad and I am new to this site. I am 26 years old, live in New Brunswick, Canada and work as an engineer and like to do woodworking in my own time. I started woodworking when i built a chest for my girlfriend (now wife) about three years ago. Now to my issue.

I purchased a six inch jointer and am getting a wavy edge when I run it across my jointer. The face joint is good but not the edge. Look forward to some input on this.

Chad

Could it be too much pressure feeding the boards?

Not sure exactly what you mean by wavy. Maybe you could post a picture? Could be that on of the knives is set higher than the others.

I agree with woodu2. If the knives are not exactly the same height at top dead center, you never will be able to get a clean joint.

i would take your knives out and clean the cutter head , a good way to do that is to blow the cutter hear with compressed air. and make sure the blades are good and sharp…then reinstall them using a knife setting jig…your prob should be gone p.s. the best way ive found to clean is use double oo steel wool…with kerosine…it doesn’t leave an oily finish

If you are face jointing with out problems then the edge must be a matter of technique or that the edge is so far off to start with that you nead to straighten the edge on the table saw first an then on the jointer.

Greetings busybee: I’ve ran into this problem a couple of times with my jointer. Nothing serious, though. My jointer was dead-on accurate, the knives were good and sharp and set to the correct heigth. It was strange. It would cause the board, which had been trimmed true on the tablesaw, to want to”jump, or skip”, causing a wavy-type edge. Then I figured it out…... I was going aganist the “grain” of the board making it do this. I just turned the board end for end, went in the direction of the grain, and solved that problem. So now I watch the grain pattern, go the right way jointing the wood…..... problem solved. Try that…. it might be doing the same thing with you. Just a suggestion. Let us know what you find out. Keep on keeping on…..........

Not quite sure what you mean by wavy. Try slowing down your feed rate through the jointer. That might help.

Could it be maybe the board is coming off of the fence and tilting to create the wave?

If it does that turn your board end for end it may solve your problem.

Fredericton NB. I will try flipping the board end for end. Although I am having a difficult time getting the fence exactly 90 degrees to the beds. I can get the outfeed side correct but not the infeed (vica versa). There is only a few sheets of paper thickness off. this may have somethgn to do with it.
