Jointer knives.

You need to set the top edge of the knives to the exact top of the outfeed table or maybe .001-.002 above the top of the table. I think I would remove the old knives and get that infeed table set first then put int he new knives. You can use a jig to install them. Make sure you get both ends set and level with the table. I have read and used a method that calls for wrapping a stone in a sheet of paper (one thickness) and sliding the paper on the outfeed table. This puts a compound edge on the knife. I have used this and it works better than it sounds. I think GARAGEWORKS has a video on installing new knives. Sorry I have not used Freud knives. Good luck.

Perhaps you might glean some useful information from Nick Engler’s video clip on setting jointer knives;

8iowa, I haven’t seen that video and was looking forward to watching it, however it told me it was unavailbable when I went to the site…?
When I setup my old used jointer that needed lots of tlc I used this video from Bob Vaughan. No jig needed. Just buy a $35 dial indicator with a magnetic base, some sort of lever, a block of wood and a hammer (lol) and give yourself an hour or two and you’ll have the knives right where they should be.

I should mention that your machine may be new enough that you have set screws to adjust the height of the blades. Look for them and if you find them you’ll have saved yourself a couple of hours lol.

I installed the Freud blades from WW supply (around $30 IIRC) on my jointer, but I haven’t used them on a bunch of different wood yet. Red oak, pine, poplar, indian laurel, cherry- all came out super clean though, so good enough for my shop.

In terms of getting the tables coplaner without a parrallelogram style jointer, it is my understanding that you have to shim the tables using whatever works (feeler gauges, pop cans, etc). See this page for a description of shimming the dovetail ways and tightening up gib screws

I am by no means an expert here, but I went through a lot of this to get my $100 jointer up and running.

My jointer is only 4-5 months old. Very frustrating that my table is sagging because I know it’s going to be a pain trying to figure it out.
