Setting knives on jointer cutter heads just got easier! Magnetic bars hold jointer knives in place flush with the outfeed table on any 6" to 8" jointer bed. This jig is much quicker and easier than working with dial indicators. Allows quick shifting of knives to avoid damage and extend blade life. Solid steel construction.

Rockler Magnetic Jointer Jig
This works absolutely great. It makes it so easy to set up your jointer blades. Would recommend to anyone who has a jointer and wants to take the hassle out of setting up your blades.

Great tool
Every jointer with knifes sold should include one of these tools. It makes setting the knifes a snap.

This knife jig works as well as any other method I've tried over the years. Just press firmly down on the jig to assist the magnets in keeping the knives at a uniform height.

Useful jig for setting new blades
It made the process very smooth to get 99% right with only 1% effort. I wish there was an official video that showed how to really tune things in using the jig.

Jointer blade setting.
After several consistently off by 4 thousandths alignments, I finally realized that it was operator error and I needed to allow the blade to sink closer the bottom of the track. I was so concentrated on having the magnets pull the blade up I ignored the fact that at times the jig is meant to push the blade down!!

Right tool for the job
I just got a jointer that is new to me, but not new and needed to install some new knives. After researching the options I chose to go with the magnetic set up tool. It worked perfectly for me with no issues.

My jointer has a single 8 inch blade. This makes it so much easier to set it to the proper height when changing or replacing a blade. Before, I would always tend to get one side a hair higher than the other.

I have a very old atlas jointer. Of course I've never used one, and I need to reset the blades because I'm getting a lot of snipe. Will this work for vintage jointers? Thanks!!
Heather T on Dec 16, 2015
BEST ANSWER: I have a Delta 6 inch and I was having problems also until I used this jig and now no more problems. It is very easy to use. Magnets hold it to the outfeed table and magnets hold the knives at the correct height. tighten the screws and you are good to go. Easy to follow instructions.
Is the body made of steel or polycarbonate?
Amac47 on Jan 2, 2016
BEST ANSWER: I just checked the assembly with a magnet; everything on the unit is steel.
Will this unit adjust down to accomadate a 4" jointer.....some do?
Greg P on Feb 13, 2016
BEST ANSWER: I see no reason that the jig would not adjust to a 4" jointer.
I have an old craftsman jointer will this work to set my knives?
Jim F on Jan 1, 2017
BEST ANSWER: craftsman has made numerous model over the yearsso without knowing what you have I can't say for sure. However, the model I have is six years old and is a 6" table. these jigs worked fine on that particular one.Sorry i can't be more specific.
Will this work on my 4 Inch jointer?
A shopper on Sep 1, 2015
BEST ANSWER: It should work as long as you can remove the blade guard and/or the fence, since the jig is made to expand out to an 8" table.
could it work with a 10 in jointer ? What is the limitation ?
Miguel M on May 7, 2018
BEST ANSWER: My guess is that it could, but not positive since I only have a 6" one. Don't see any reason it couldn't, but I have not had to use mine for a while either.
Step 3 (fig 1) of the instructions for this jig has us find the top center of the currently installed knife using a straight edge. We then draw a line on the fence so the scribed line on the jig can be aligned with that line we drew on the fence. It seems to me that this top center line we are finding and then marking on the fence is only accurate if the current knife is installed correctly. If the knife is too low, it will not contact the straight edge, if the knife is exactly at the correct height, the line we draw on the fence will be correct, but if the knife is installed too high, the line will be wrong as the knife will contact the straight edge before top center is reached. Am I missing something or do my knives have to be installed exactly right to establish the line on the fence so the jig can be aligned correctly for the first knife change? Also, Step 4, Fig. 2 has us draw another line on the fence further back on the outfeed table so the other scribe mark on the jig aligns with it. Why?
Greg D on Aug 3, 2017
BEST ANSWER: Hi Greg,
I am not an expert with this device, but I have used mine a couple of times. I have not encountered the exact problem you are describing. However, it seems to me, that if you rest your straight edge on the infeed table so that the end of the straight edge extends over the cutter knives, you should be able to overcome this problem. Once you have positioned the straight edge over a cutter knife, you can rotate the cutter wheel to maximize the height of the knife. You may have to adjust the height of your infeed table as well, in order to accomplish this. Hopefully this will help. Good Luck!
Is there a tool like this that could be used on a13 inch planer?
janice h on Aug 15, 2016
BEST ANSWER: I would say no! A jointer has an indeed table and an out feed table. The out feed table in conjunction with the fence (not part of a jointer) is used for the high point of each blade!. The planner is a constant adjustment every time you take a cut! The jointer usually has limited adjustment! Hope this helps, my Dewalt Planner has two magnetic blade setters that are used for blade height, they work in a similar fashion, but it is a different design withe the same result!
Has anyone used this on a Ridgid jointer?
Christian M on Jan 20, 2016
BEST ANSWER: no, but I don't know why it would not work on any jointer.
Does this work with spring loaded knives? My old (1998) craftsman has two spring under each knife
Dave I on Sep 3, 2018
BEST ANSWER: Yes it does I have a jet planner and it works great
will this work with carbide tipped jointer blades?
Rick D on Nov 8, 2016
BEST ANSWER: Tungsten Carbide has very low magnetic properties. The Tungsten Carbide inserts on your jointer knives are probably blazed to the steel blades! The Rockler Jig has a relatively strong magnet so it may work. You should be ~1/8" or less to the magnetic steel, try it, it may work!
