Homemade Joiner Knife Setting Jig

Every time I changed my joiner knives I had to borrow my buddy’s Magna-Set setting jig because I didn’t have one of my own. I went on line and priced them and the cheapest one I found was around $39.00. Being cheap, I said to myself, self, you can make one. So I did!

I milled some hard maple to 5/8”x5/8”, then I cut the squared maple into two 6” long pieces. I laid out the centers for 1/4” dia. rare earth magnets 9/16” from either end and then 3” to the center of the middle one. I used two 1/4” dia.x 6” long cold rolled steel rods for the guides. I centered them 1” off of either end.

After drilling the holes for the magnets I dry fitted them in the pieces of maple. I then turned the maple bars upside down on my table saw table with a piece of plastic in between and carefully lifted the maple bars leaving the magnets exposed and in place. Next I put a drop or two of super glue on the heads of the magnets and carefully placed the maple bars back over them. I put weights on top of the bars to hold them firmly against the table saw top until the glue dried.

I epoxied the 1/4” dia. guides to the fixed bar then I waxed the guides as well as the holes in the sliding bar. I had all the materials on hand but even if I had to buy the stuff I would maybe be out $5.00.

Thanks for looking. This project was almost too simple to post but i like simple I hope some of you do too :)

It’s an excellrnt Idea, should make one out of a metal since they are made of brass and steel and you won’t have to worry about fluxuation from humidity and it’s just a couple of bucks more. Just saying!

Awesome. I will be making one this weekend. I love being able to make things with stuff on hand, instead of purchasing.

I did something similiar….I used a piece or 1/4” plexiglass (6” x 12”) and glued earth maginets to the bottom.

Is that a Delta/Rockwell jointer by chance?

Great idea, I too need to make one of these..and coincidentally enough my blades badly need to be sharpened right now!

GG, yes, it is an early 1960s model Delta/Rockwell jointer.
