Your question sort of doesn't make sense. Planers plane so that that the side being planed is parallel to the side running on the table. It sounds like you have a jointer problem or that you're not holding the face side snugly against the jointer fence. Or your order of operations preparing stock is wrong.

Unless I'm missing something.

James-
Do you mean that the planer is surfacing boards so that they end up with a taper- ie one edge is thicker than the other when lying flat?
Are the blades adjusted properly, and are the blade securing bolts/nuts tight?

How does the lowering/raising mechnism work on your machine? Is it possible that something has gotten loose and allowed 'loss of parallel'?

Time to get some scrap and the calipers and do some testing- after you give the machine a good check for loose bits.

Steve is right, though, about the 'square' thing. That's a job for the jointer (or hand plane).

Cheers
John

Always have to double check; never trust powertools. It should be a automatism, when you get a piece out of a planer, or of a jointer, band saw, table saw, sander, etc, to check it with a square, and with rules or calipers on EVERY faces, that's how you confirm the square of the piece. For needs of lutherie, you always have to DON'T trust power tools. I don't know your planer, but they're always solutions for almost any problem. And sometimes, the only way to get a perfect job, is to finish the job by hand.

I have to do more testing , however its appears that my materails are coming out 2-3 degrees thinner on one side than the other .

I dont use a jointer . so it cant be that . will do more testing tomorrow and let you know what i find.

First, check your planer blades. Each blade needs to protrude from the cutter head exactly the same amount.

Second, if your planer bed is truly out of parallel to the cutter head, most planer's have a simple adjustment for this. I'm not familiar with the Grizzly, but if you check your manual, I'm sure there is a simple adjustment.

Third NEVER ASSUME THAT YOUR TOOL IS SET UP PROPERLY OUT OF THE BOX. Tablesaws, jointers, planers, or whatever -- expect them all to arrive in your shop in need of adjustment. Read the manual and check/adjust everything possible. After you start using them, check them often to verify that everything is square or parallel to whatever it should be square or parallel to. These regular adjustments are part of fine woodworking. It's no different than making sure your plane blade is cutting evenly on both sides of a handplane. The fact that a tool needs adjustment does not mean it's a bad tool. It just means you are a woodworker.

In your owners manual is a set up page. That should tell you how to set the bed parallel to the blades or if you did put blades in wrong you just need to reset , start with the blades and work backward. I got rid of my planer a long time ago. The thickness sander is more suited to luthiery

Sorry James my friend I can't help because I don't have or use a planner. As John said above the only time we typically discuss planers here is to answer a newb's question that they don't work well for the thicknesses that you need our plates to be.

Good luck though with your planer.

Have had this unit several years and have never had any trouble , apparently somthing has come loose . When I book match I cut a 3/4" Piece in half and plane to approx 1/4" and then thickness sand to desired thickness . I also use it to Plane my neck blanks after glueup and they have always been right until last 2 . so somthin has moved .

Like the old man said , if ya aint screwing somthin up , ya aint trying near hard enough !

If your blades are correctly installed, check the adjusting chain & sprockets. If you chain gets loose, you can skip a tooth on one or more sprockets. Your manual should have some good set-up tips.
Also... check for up / down slop in the movable deck. The lower deck of my planer loosened up recently & caused me a bit of grief.

If the knives are right, looks like on that model either one of the 4 lead screw bolts has moved or one of the 4 posts has pulled out from the base.

run a piece of wood on the extreme right side of the planer and one on the left. Compare and tell us what you find.
