how to avoid nip at end of boards on joiner

I think this subject has almost certainly been addressed in this forum some time previously, but I am not sure how to look it up. I have tried multiple means to try to avoid that nip in the surface at about 1-2" at the aft end of boards I am running through my 8", 240 volt, 67" long joiner, but have not found a consistent method that avoids it. The joiner platforms both before and after the head are firmly affixed with a set screw. Any suggestions?

Your outfeed bed is lower than the cutterhead knives. Unplug the jointer, set the outfeed to be level with the top edge of the knives, then lock the outfeed down; you won't have to move it again.

Thanks, David! You were right. The outfield was slightly lower than the top of the knives. I've got them level now. Best Regards, Cassidy

On my jointer, setting the height of that outfield bed is a bear. It seems that I get it adjusted juuuust right, but when I tighten the locknut it moves a smidge. That was one of the motivators to move to a Byrd Shelix cutterhead. It was still a royal pain to get set after I changed the butterhead, but I shouldn't have to do it again!

The two types of jointers ......

There are fixed outfeed jointers, the lees expensive ones like older 6" Craftsman and adjustable ones like newer Craftsman and most other brands. I had an older Craftsman and finally gave to a woodworking friend who needed one. That left me with the newer model which I still use regularly.
When adjusting the knives on the fixed table model I needed to determine how far out of the cutterhead to set the knives. It's not easy to find that answer on the web, but I finally found it:
http://vintagemachinery.org/files/PD...nterKnives.pdf

This comes much too late to be of help on the old model, but still useful for any jointer. You typically just remove the dull knives without any regard for where they were set above the cutterhead body. If your jointer has "jack screws" then they will be your best guide for that height adjustment. My older Craftsman did not have them so it was just my best guess on where to set them. According to the PDF above, the "heel" of the bevel should be 1/16" above the cutterhead body. The heel being the start of the bevel on the knife, not the tip.

From then on, just make them all the same height by the moving scale/block method or a dial indicator or a knife setting jig, which ever you have. On my planers I use a "straddle" type jig because there is not outfeed table to use as a reference. Like these which should also work on a jointer, but I've never used them for that:

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Just a quick follow-up note. I adjusted the outflow platform as David suggested. The height at top dead center of the blade was only very slightly higher - maybe 1/64 o 1/120th of an inch - but when this was corrected, now after running several boards through the jointer this afternoon, I have had no nibs at all at the end of the boards at all.
