For some reason I cannot get a true flat side when I run a piece on the jointer. One end is thinner than the other and it’s not snipe. I have made a lot of ships fly and wasted a lot of wood trying to flatten one side of two oak pieces for glueing purposes. I would appreciate any help.

Make sure the infeed and outfeed tables are perfectly parallel. You can taper the cut without getting snipe.

Hope that helps.

When was the last time you changed the knifes?

I don’t know if you saw this post or not but Tom Hintz does a good job of addressing this issue. I have found that I get tapering, especially when face jointing, when (1) my knives were set higher than the outfeed table and (2) my technique with feeding the board through the jointer. I usually got tapering when I put too much pressure on the infeed side of the board. One thing that helped my face jointing, and made it safer as well, was this push block:

Jointer Push Block

With this block I am able to maintain pretty even pressure on the board as it passes the cutterhead and it is relatively easy to transfer the pressure to the outfeed side of the board without losing contact with the board.

Is is obvious that there is an alignment problem of ether your feed tables, Back angle guide or knives maybe all 3 to some degree. Chances are about 75% that your parallelism is out. The best thing to do is get the Manuel for your joiner and follow the manufactures instructions. I wasted a lot of time and wood listening to people that said do this or that. No offense to any one, but I found you just have open the books and get your hands dirty on this kind of thing the nice thing is your angles and cuts come out better when you tune any machine and your more likely to keep it that way and not let it degrade to the point that you have to do something about it.

Worse comes to worse and you cannot fix, run one board face up, run the next board face down and so on. If the first is 92 degrees, it will match to an edge on the next that will be 88 degrees. works like a champ. I do it even though my jointer is “flat and at 90 degrees”. You can never tell.

Thanks everyone, looks like I have a full day of setting up my jointer. Hope I can find a manual on-line. I didn’t buy the jointer new. I found it in the woods while hunting. But that story has already been told on here. Thanks again, everyone.
