I hope you are not tired of looking at another kerfmaker. There has been a few in the last few days. My version is exactly the same as Bobthebuilder’s as I thought his is the most simplified version with blade adjustability. My only change was to move the wingnut hole up as close to the arm as possible to allow me to cut wider dadoes, up to 2 1/2”.
My first dado was a hair loose. After I tightened the screw a little, the fit was perfect. This tool will definitely have a place in my tool drawer. I want to thank all those who posted this great device and ideas.

Simon, this is another nice interpretation of the kerf maker. This looks like a nice addition to your shop. I may even have to get on the band wagon and do one of these as well. It sure beats simply running test pieces or calipers to determine the dado’s width.

This has got to be the largest shared/copied idea ever. So nice when a simple and useful project like this is posted. Thanks to everyone contributing!
P.S. I also made one.

Got to make one after my vacation. Btw, would you please share with us the measurements of the pieces so we could make a duplicate of yours more quickly? Also what’s the size of the bolt / wing nut? Thanks.

Great job.
I realized the placement of the bolt could be problem with mine today. I was trying to avoid that knot in my piece, but I think I will move the nut to the other side like yours. Lots of great minds working together, I love it!

Chuck,
The bolt and wing nut are 1/4”. The bolt is 1 1/2” long. I also used a lock washer to keep the bolt from turning when I tighten the wing nut. Hope it helps
Here is a Sketchup drawing of my kerfmaker.

Sweet. Very nice.
When you go look at the original compared to this, the difference in simplicity is amazing. And yours even looks nice too. We all have to ban together and do the same treatment to some other shop jigs.

Great sketches. If anyone still wondered if it was a good idea to be a LJ, the thread on the Kerfmaker should remove any doubt once and for all. Where else could one come across so many generous ideas and woodworking buddies? My favorite saying again: “There are no hard times for good ideas.”

I assume the screw at one end of the jig is an adjustable spacer for the saw blade thickness?
I added this to my favorites. I’ll make it when I have some free time. It looks to be a very useful device.

Dovetail, you are exactly correct. By adding an adjustable screw you can pretty much use the kerfmaker with any blade thickness.

Simple Simon.
Had to say that.
Made three so far and Your pictures helped explain the screw in the end.
Now to test them.

Nice and simple. I’m going to make one of these. Nice clear pictures showing it at work and sketch-up drawing. Thanks Simon.
