I was getting frustrated with the jointer at work yesterday because it kept putting a twist in some table leg blanks I had glued up. The cut was also very choppy…
So I made this knife setting jig and tuned that baby up. Now the knives cut smooth as butter and level as can be. Love this thing! Made setting the knives accurately easy as pie!
This is a jig that can be found on Wood Magazine’s site here:

I will suggest you make one correction though. The diagram shows the pilot hole being 7/64” diameter and 5/8” deep, and the shank hole being (larger) 5/32” diameter and (deeper) 7/8”. I suggest reversing the depths…

Now to order find some 3/4” magnets and make one of these for MY shop… Oh. And order some dial indicator tips from MSC.

This looks as nice as the one I spent $100 on.
Nice job my friend.

That is a very nice way to make accurate settings. I made two of them with drop indicators from Harbor Freight( they are quite accurate). I use vertically like you have on to set the height of the router bits and table saw blade and one horizontally to measure the movement of the fence on the router table so I don’t need to use scrap pieces after each change to see how it cuts.

Nice work!!..............Jim

When I still had my jointer I used two ground magnets on the outfeed side of the jointer. They held the cutter up while I tightened the screws! That jointer did not survive the move to CA, it developed a large crack in the base casting!

Before that I used an indicator and a magnetic indicator base … I always thought it was way too much work!
