Hey Man ,I’m new to this site I just joined today. I live in Pensacola, Fl. I started Woodworking Two years ago at that time I purchased several machines that I knew very little to nothing about. I’ve seem to have gotton my jointer smooth out of calibration and need some help in a bad way. It is a parallelagram jointer so each table has four cams two on each side that you move up or down in order to get the tables co-planer. I would appreciate it so much iF SOMEONE CAN HELP. iF SOMEONE LIVES IN THIS AREA I would be willing to pay someone to come over and fix this rascal.

ziggy, welcome, glad you found the LJ. This won’t be the last time. Here is a video a fellow LJ’er put together showing how to adjust planer knives and bed on his powermatic.

Yeah I’ve watched that video and its a pretty good, but the problem I’m having now is are have been having is that the out feed table was moved so what I need to do is to somehow get the out feed table parallel or even with the top of the arc of the knife inserts from front to back. A]. I have the Helical Cutter Head so the knife inserts are just a little harder to work with. The infeed table also has a depth gauge so that has to be considered before you just arbutraily (oops ?), start moving tables. The Tables have 4 cams two on each side that you turn in order to raise or lower that side and area of the table. Also once you adjust one it effects the other three as well. Bottom line is If I can get the outfeed table adjusted then the infeed table will go much easier. But how to get the Out feed table even , front to back with the top of the knives? Does anyone have some type of method to do this? Thanks Chris

Hi Ziggy. I had a similar problem with my parallelogram planer. I tried to use a drop indicator to get the top of the cutter to perfectly match the outfeed table and that was too difficult. Here is what I did to get it working real nice.
I lowered the outfeed table so it was for sure below the cutter.Using a about a 12” long board,I set the infeed table for it to cut off about 1/16”. Then I fed the board through it just far enough that the board went about 1” over the outfeed table and shut it off. I backed off the board and rolled the cutter head so the cutter was below top dead center and not in contact with the cut area. Slide the board back over the outfeed table and then start adjusting the outfeed table up until it just touches the cut area. Repeat to be sure you are not too hign. Lock the outfeed table and try a full cut. It should come out level and with no snipe on the trailing edge of the board

I see what your saying Jim. I see how that would definitely work to set the outfeed table dead on at the cutterhead. I wish that was the only problem I had. See my problem is that all eight cams have been moved I have to get the whole out feed table even with the knife inserts. Helical Cutter head. I can get the front part of the table even with top arc of the knives but the back of the table is not level with the front. You can actually make the tables parallel and yet still be not even with the knives. When this happens the knives are contacting the wood even before or after the center of the cutter head thus causing a terrible cut. Thanks christopher Wade
