Please help, or my Grizzly Jointer is going to the scrap metal yard!!!
My 8″ jointer will not stop making tapered cuts. I’ve read the books, looked online, watched videos, but nothing is helping me. Things I know, or at least think I know… I know the tables must be coplanar. I bought an expensive straight edge to do this and unless my understanding of math and science is off, the tables are coplanar. I used feeler gauges and the straight edge; there just isn’t any other way to do it. I know the outfeed table needs to be level with the blades at their highest point. Again, I have the expensive straight edge to make this a reality. Ok, so everything is parallel, to the best of my common sense knowledge, and I still get tapered cuts. So my technique could be the problem. It was never a problem before this mess happened. Something else, after I true everything up, and set the depth (for an inevitable tapered cut), I lock the table down so it doesn’t move and it knocks the infeed table out of parallel. Ok, so I don’t tighten the lock down so this doesn’t happen; everything looks good, and BAM!!! Another tapered cut. What is going on? I am so frustrated. I’ve been messing with this thing for over a week. I’m ready to melt it down.

You are obviously new to jointer use. You should read up on how to properly square up stock. I'm not sure that it's even possible to ever get a completely straight cut ( where your jointer removes the same amount of material along the length of a board). The jointers prime or main purpose is to make one side completely flat or straight. Once you've established that then you should run the piece through your planer( flat side down) to get those two oppossing sides parallel , or you could also cut the opposing side on your table saw( flat side on the fence). Then you can run one of the other sides through the planer to get it completely flat. Then you can run it's opposing side through the planer to get it completely parrallel, thus producing square stock. So as you can see, you can successfully put your joiner to use in squaring up stock, by using it in conjunction with your other tools. In my experience I've never relied on my jointer only to produce completely square stock. like I said, I"m not sure that it's even possible. I also have the Grizzly 8 inch jointer with the spiral cutter head on it . Hope this helps ! Happy woodworking !
