I am having some issues with my jointer. I have the DJ20 jointer. When I make the fence square to the infeed table, then it is not square to the outfeed table and visa versa. My fence seems to be straight. What else could cause this to happen? Obviously that would mean it is in the tables, but I have never moved either table, and am a little scared to do so…Is there a way to “tilt” the table? I know I can raise and lower them, but I didn’t know they moved in other directions. This is the one tool I feel like I don’t know that much about mechanic wise. Thanks!

You need to shim one of the tables on one side. Brass shim
stock will do it or if you have a feeler gauge you can break
it up to make shims.

I don’t know that jointer. Most have a set screw
on each side and tightening that screw can sometimes pull
that side of the table down a little. Loosening a screw
allows the insertion of a shim.

Thanks Loren. When I got it, it had a lot of surface rust on the tables, but I don’t think anyone had ever removed the packing grease, so I took the fence and all the components apart for a good cleaning. So I am familiar with that, just not the tables. I guess the only way to learn is to tear it apart lol. I do have a cheap set of feeler gauges if the set screw doesn’t work.

Gr8 link there Loren. You’re going about it the right way Shelly. You’ll learn more about your tools when you dissect them. Good luck with the fix.

I’ve used cut up pieces of the thin aluminum Pop Cans for shims on my Grizzly Jointer tables. Seemed to work great for me.

NO, NO, NO! Don’t resort to pop cans, you have a parallelogram jointer. Just adjust the cams that raise or lower each corner of the tables.
Brass or aluminum shims are only for jointers with dovetail ways.

And really check that fence carefully for a twist, before you start messing with the tables.

Here’s a quick visual check for you Shelly. Wind the infeed table up to zero and place a straight edge along it and the outfeed table at each side. There shouldn’t be a gap between the straight edge and the tables. If there is a gap, it will indicate where the problem is. If the machine was handled by the tables it might have caused the problem.

Great video on setting up a jointer like yours, with the cams for adjusting.

Thanks everyone!! I have almost completely fixed the issue. Didn’t have time to make it perfect, but it is way better. It was moved by the tables since it is so heavy and we only had a 2 ppl to help move it. The one of the tables were drooping at the ends, so I raised the infeed table. The outfeed table was also just a hair too low. It was perfectly level with the blades, and was causing snipe and the wood to barely catch. I must have caused that when I changed the blades. Grizzly also has a great video I found on adjusting their machine(which is the exact same as my delta). I found and watched it before I got all these great replies. The woodwhisperer is great also! If anyone has a machine that grizzly has remade, I would suggest checking out their site if you ever have questions about it. They have a ton of videos and adjusting them and working on them, even if it is just changing a blade. They even have a video on how to put a helical cutter on it if I want to! Thanks to everyone for their replies!! I did exactly what pintodeluxe describes in his picture. Oh and Shawn, I would but since I fixed it I don’t need to sell it now;)
