How to use a Kerfmaker
Ok, many asked me this question, and I have seen it again and again on LJ.
If you need to find out how to make one, you can see my Kerfmaker 'Brass'n wood'.
Another fun gadget is the tenonmarker:
I’ll try to explain, as well as I can, feel free to ask questions if I do not make myself clear (I’m only human):
Collect what is needed, in this case a base stock and two thinner side stocks, and of course a Kerfmaker.
(The pipe and matches are optional, and I must warn against smoking…).
Measure out where you want your kerfs to start, and mark it carefully with a little arrow showing what direction to cut.
Her you see the setup.
Now put the stock you want to cut out into the gab of the Kerfmaker, and tighten it up.
Now you have the only measure you need set up.
And here you can see the Kerfmaker’s ‘mouth’ with the correct size set.
Now you need to figure out how deep you want to cut, I’ll make a flush cut straight with the surface, you can simply measure, or you can use a Height-, length gauge .
Set the thickness of the stock on the gauge, and lock it.
Now you set the height on your table saw after the gauge (it’s really easy).
Remember to roll the blade, so you end on a tooth top.
Now bring your Kerfmaker to the table saw, and loosen the finger screw in the back.
Hold the back of the kerfmaker against the blade, and adjust the thumb screw until it has same thickness as the saw blade.
Now you are ready to use the Kerfmaker.
Now set the cut up, and lie the Kerfmaker behind the stock, and use the shortest part (see photo), then lock your fence stop. And you are ready to make your first cut.
Now rise the Kerfmaker so it’s full length, and move the stock up to the Kerfmakers front.
Make your next cut.
Here you see both cuts made.
Now clean up the cut, either with repetitive cuts on the table saw as I do here, or simply with a chisel.
And here we are, a perfect fitted kerf.
If it’s not perfect, you simply need to adjust the back screw a little for adjusting the size.
And here you see a perfect fit, I can hold it up, with no glue used.
I hope this could solve the magic of the Kerfmaker, an inspire to make or buy one,
