Jointer knives placement??

Just get them all set the same.
Then you can adjust your outfeed table up or down for the perfect cut with no sniping.

I use a dial indicator to set my knives even to the out feed table. This is actually just a reference point at this point but also very close to where they end up. Then I lower the out feed table about 1/8 or 1/4 lower than the knives. I then make a make a cut with a piece of stock I know is straight until its a inch or two over on to the out feed side. Then I raise the out feed table up to just barely touch my cut. This works for me. And like Aj2 says if you get any snipe the out feed table it a tad low.

Ditto. Get em even. Fine tune table height later.

You don’t want to be messing with the outfeed table (if you even can, some designs have immobile outfeed tables). You reference everything off the outfeed table. You make the infeed coplanar to it. You set the knives to be a thousandth of an inch or two above the outfeed table.

Leave the outfeed alone and adjust everything else to it.

I set my jointer (Delta DJ-20) knives with just a straight edge. Straight edge is placed on the outfeed table then knives are raised until they just touch the straight edge. This sets the knives at exactly the same height as the outfeed table which has always given me excellent results. I have never adjusted my outfeed table and would advise against messing with it.

Unless there’s something seriously wrong with your machine you should be able to lower and raise your outfeed any day of the week. Jointers are designed to keep the tables in plane with each other as they are moved. Up or down
So don’t be a scaredy-cat like ^ guys. Your not going to hurt nothing.

The infeed and outfeed tables of a jointer are NOT aligned (in plane) with each other. The outfeed is aligned with the wood surface beyond the cutter head which is clearly different from the infeed side.

This is for those of you who have straight planer blades, not the spiral carbide type.

Here is a hint: If your present planer blades are set properly but just need replacing, LEAVE THE HEIGHT ADJUSTMENT ALONE when removing the old blades and re-installing new ones. Straight planer blades are machined to all be the exact same height. You should be able to simply drop the new blades in and tighten up. This should hold true on properly machine resharpened blades. If you do this, its not the nightmare job blade change can be. Further adjustments should only be adjusting the infeed and outfeed tables.

I agree.

I assume you meant jointer blades, not planer.

It’s definitely not the case with my Jet jointer that they just drop in and are aligned. I use a magnetic jig to set them at the same height as the out feed table.

Then again, maybe you are thinking of a planer since that’s how the DW 735 blades work.

I move my out feed table all the time. Not a problem in the least. I’ve been doing it on my present jointer for the last 19 years. I can’t think of a single reason to change now.

Did anyone read the instructions that was with the drawing in my first post?

It started with “I use a dial indicator to set my knives even to the out feed table.”

What jointer do you have Alaska guy. I remember seeing part of it in a post once I didn’t recognize the make.

I think some guys on this forum are watching too many you tube videos like the wood whisperer and other cornballs.
That’s why so much fear and confusion about jointers.
