Edge Jointer: Tapering Problem?

Rob,
Are you placing downward pressure on the intable side of the jointer? From my limited experience, I get better results (no tapering) if i apply my downward pressure on the outfeet side of the cutters.

I am mostly self taught from watching Norm and Marc. I believe I am correctly placing pressure evening toward the fence and table.

sounds like the opposite of Spaids problem. Just like him, I’d start by checking the height of your outfeed table to be sure it is level with the top of the blade’s rotation.

Indulge the noob in me—wouldn’t an outfeed table lower or higher that the top of the blades result in a more or less aggressive cut along the whole length of the board?
I could see a taper occurring if the angle of the outfeed table was off from front to back.

Both your infeed table and outfeed tables need to be in the same plane. Use a good quality straight edge to check this adjustment. If they are not in the same plane, I would think that is causing the taper.

Search the internet for a tune-up procedure.

Setup…Check your in feed and out feed tables. Out feed table needs to be exact height as your blades.
Technique…your pressure should be applied just a few inches past the blades on the out feed table. you should have no gap between your board and the out feed table. I just use my joiner to clean up an edge. If I want the edges parallel I use my planner.

What Dennis said. It sound like your outfeed is higher than the blades, which will lift the board away from the blades as you apply pressure, so the last part of the board going across won’t even be cut.

I had that same problem with my brand new Grizzly jointer. I called their technical department, and they had me stretch a straight edge across the length of the infeed/outfeed tables, and measure the gap at the ends. Then he instructed me to shim the ways on opposite side that was low, bringing it up on the low side. It worked!! I attributed it being off due to me and a co-worker lifting it on to it’s base by the tables. It’s perfect now!!

I vote with the guys who suspect that the infeed and outfeed tables are not parallel. You will need to obtain a very accurate, and long, straight edge. I recently purchased the 50” Veritas aluminum straightedge from Highland Woodworking and it has been very useful in machine set-ups.

here is little video i did…might help…i agree you have to be adjusted correctly or you will experience what you are describing http://www.youtube.com/watch?v=UqVkISnNx0w
