My version of the Kerf Master, I made out of scraps of oak and a little bit of redwood. Rather that using a sliding dado I just built a box around the movable part. There is a slit in the redwood top to allow for compression of the wingnut to hold it in it firm. There is a 1/4” slot in the movable part that accepts the 1/4” carriage bolt and wingnut. I just used a deck screw to make the offset adjustment. I personalized it with my initials, using a aluminum foil template, a magnifying glass and the sun. Fun to make, but haven’t really used it yet other than testing it out. Total cost less than 50 cents.

Cool. The most versions of any jig that I’ve ever seen. I’m still not clear on how you guys are setting the offset with these?? or are you just setting it to one blade only?

David,
I set the offset by trial and error, by screwing in the deck screw more or less depending on what is needed. That isn’t a problem as I will likely be using only one blade. With this I can easily adjust how tight or loose I want the joint to be.

Michael,
The sliding piece functions like a caliper for measuring the width of the piece you are wanting to inset into a dado or rabbet. The end that sticks out minus the screw offset is the is the width that you need to move the wood from a stop to achieve this amount of kerf.
The following link has a movie showing how their version can be used.

Al,
You said to David that you set the offset by trial and error? Watch the Bridge City’s video closely, precisely the last minute. They show how to set the offset by ripping a scrap piece of wood partially, then crosscut half of it, slide the cutoff against the remaining part and adjust the set screw until the offset is equal to the gap. No need here for trial and error, only to tighen or loosen a joint, as you mentioned. The same technique applies setting the offset with a dado blade set.
And thanks for sharing your free pyrography technique. This is clever. However, it must take a while to cut the letters out of the aluminum foil.
Best,
Serge

Serge,
The template didn’t take too long. I glued almuinum foil on the the wood with a glue stick and then glued my paper pattern, which was a word printout of the initials, on the aluminum foil. Then cut through both layers with an exacto knife and used twezzers to pull up the lettering that I cut around.
Having a fixed holder for the magnifying glass allow me to just hold the wood with both hands and move it around to complete the burning. It goes pretty quick. Then removing the foil and doing a little sanding gives a finished look to. A homemade laser print, without the cost, but missing some of the fine details.
You are right about using the technique to determine the offset, I was only thinking about using it for a single blade rather than a dado blade set.

Nice way of doing it. As I said, “Keep it comin’.” Together we’ll be making the longest chain project here!
Btw, Serge, Congrats to you for another top tip in the Wood magazine. You sure sets the bar high for us tipsters. At the current rate, for every 5 tips you’d produce, I might only, with much effort, squeeze in one.

Thanks Al for the details of your technique. I copied/pasted it in Word so I won’t forget it. This is very clever.
I believe your technique would work as well with contours of pictures and/or drawings. Something new to try. I’m actually making twin hutches for my kitchen and I wanted to camouflage the screw heads which hold the shelves from the sides with hand painting or pyrography. Using your pattern should be a good way to go. To be followed! Thanks again.
Best,
Serge
