Totally possible to induce a U in the middle of the board. Could be either your technique or the jointer itself.

Do you use a push stick/block on the jointer? do you keep pressure on the outfeed side when finishing the board? Free hand?

When was the last time you tuned up the jointer, checking for square, level, parallel and co-planer? Knives set correctly?

your clamps are inadequate for that kind of multi-board glue up, if you take a good look, you will see they are also bent. you need to get a couple of bar clamps, aluminum clamps or I-beam clamps for that, They will provide you with a flat surface to glue on.

Now if that doesn’t fix the problem, you need to square the fence up, as it’s probably a shave out of square assuming uneven clamping preasure isn’t the culprate.

P.S Crashn.

The tables on a jointer are parallel. There are two schools of jointing front and back table jointing, both work equally as well with no issues. However trying to tell a back table jointer to become a front table jointer is what almost made me lose a finger. I was lucky and fast enough just to get a cut on the tip of my finger, but I”m going to have to say something about the “safety” of trying to change the style of jointing someone does.

I’d go with everything said so far, especially TCCcabinetmaker’s remarks. I’d also add, dry fit your boards before gluing and make sure you have a good fit.

If the ends don’t draw tight at glueup, it may be snipe from improper jointer setup.
Adjust the outfeed table level with your knives. Make sure the tables are co-planer to within .002”.
Set the infeed table for a light cut and try again.
Good luck.

let him go through the simple stuff first before going to the most complicated stuff…. simple then go from there….

Thank you all. I will first get some better clamps. Before I try jointing any more wood, I will go over the jointer from stem to stern. I’ve already discovered that even though my fence is square to the table, my boards are coming out a degree off. So, I have a blade issue for sure. It’s also squeaking when in use so I may have a bearing issue as well. I’m going to cut these boards apart and use the wood where I can and start over on these drawer faces. I was actually able to pull some of these boards apart with my bare hands.

Oh, to answer the first question…I use a push block in my right hand and keep pressure on the board against the fence and down on the blade with my left. I’d say I keep the pressure on the back through the cut. I’ll listen to any advise on a better way. Thanks!

Ends of the boards not gluing up. Sounds like your knives may be set a little high – Outfeed table too low. Try to raise the outfeed table to where the knives just barely touch a straightedge laying on the outfeed table.
Go on The New Wookworker site. He has some good videos on jointer setup.

MagicMark,
I was always taught to keep pressure on the outfeed side, keeping the freshly jointed face against the table once enough was present to get a push block on, then the right had just provides forward pressure enough to advance the piece. I might also say that your outfeed side may be below the TDC of the blades.

TC,
They should be parallel, but if the infeed side slants away from the cutter head (the first most portion of the infeed side), then they will not be parallel. In that case, one would have to shim the dovtail to get it back to parallel.

crashn,

That’s still a more complicated issue, remember your kiss rule, if it’s one of the more simpler issues deal with that first, but if it’s still not working after he’s trouble shot the simple stuff, then we go on to the more complicated issues. And having almost lost a finger due to a stupid foreman not knowing that they should be parallel, I do take some serious exception to people saying it can only be done the one way…

TCC,
agreed. Start with the simple stuff for sure. I lost part of my finger (not woodworking related), so I can feel your pain with stupid supervisors !

you should take a smoothin plane and hit the center of your glue edge before glueup that makes sure your ends are not gapped if the bord is 24” long hit the inside13 or 14”justa couple lite passes

The advice I received from all of you is priceless! Thank you so much! I dove into the jointer and found that my fence was moving after setup. I shimmed the fence pin and solved that problem quickly. I was still getting off square cuts. I checked each blade. One was low, one was slanted (the culprit) and one was too high. I reset all three to just barely touch the square from the outfeed table. The jointer is working fine now. I also took the advice on the clamps and found the job to be much easier and requiring much less force. I changed the design and I like this look better anyway.
This will be our drawer face. Walnut on top and bottom and cherry in the center. What do you think?

Also, I’m working on my hand over hand technique and I’m getting better cuts. This takes practice to get right. I guess no matter how many tools you have, if you don’t learn how to use them they’re worthless.

Results. Good advice. Good tools. and the will to make it happen. I’ve got a long way to go, but I’m making strides every week. Drawer face 1…check. 2 and 3 are glued up and drying. Sand and polish time tomorrow. I’m almost ready to start on the sink basin cabinet.

Thank you. Puns are in “grained” in my head too. I just “plane” love ‘em. Seems like wherever you go this “joint’er” that, puns are always funny. lol

Mark, Nothing more frustrating than a jointer that won’t joint but nothing nicer than one that works like it’s supposed to. Glad you got your beaten into submission.
