Topic tags/keywords: jointer

Yes or no: should the jointer blades be above the outfeed side just enough to move the straight edge a hair?

Logic says that if it doesn’t move, the blades aren’t touching, ergo they’re too low.

Right?

I’ve done the test where you run a few inches of wood over and stop in the middle to ensure that both sides of the board are flush with the tables, and it looks good to me, but there’s still room for improvement in the edges I’m getting.

TIA

I have my jointer set up to where the blades are level with the outfeed table.

About .002” higher than the outfeed .000” flush can lead to issues.

Right, that’s the goal.

My jointer doesn’t move the blade when everything is set right. After the knives get worn a little and small nicks start showing up I will lower the outfeed slightly. If I don’t the nicks will bump into the edge of the outfeed and push up the wood out of the cut.
The easiest way to set your outfeed height to the top dead center. Lower the outfeed below the infeed a 1/32 is plenty. Turn on the machine run a board on edge when it’s just a couple inches or more over the outfeed turn off the jointer. There will be a gap between the board and outfeed raise up the outfeed table till I touches it. This is where your jointer is cutting top dead center.
Here’s a video that shows how to set outfeed height.

Dead level with the outfeed table… unless they are freshly sharpened/unused, in which case putting them in 0.001-0.002” allows tor the thin fresh edge wearing down in the first few passes.

BTW: I used the ‘move the stick’ method for years and it wasn’t until I got a dial indicator did I realize how inaccurate that method is.

Cheers,

By the way, this is a variation of the technique I was talking about – you run a little of the board through, stop, and see whether both sides of it sit flat on the table. If it’s too high, there’ll be a gap on the outfeed side, too low and there’ll be one on the infeed side.

Excellent idea Nick I hadn’t thought of that. I’m going to try it tomorrow in the morning when shop isn’t 1000 degrees :)

Yeah, it’s hot as blazes here too (Los Angeles).

I wish I could take credit for that idea, but I saw it somewhere and remembered.

I often do what he does in the video at the 8:00 minute mark. I lay a piece of computer paper on the out feed. That sets the knifes a hair high. Set like that it will move a stick about 1/8 on and inch when I rotate the head. Works for me.
