And now, a kerfmaker!

The “themed” pics should give a hint about who I got the inspiration from… give up?

mafe of course, and his kerfmaker

I really like the look of it (and all of mafe’s tools) so I felt I had to try to build one, went with whatever parts I had available so no money was spent to build it.

Woood is some leftover tzalam hardwood, from a gift box I made earlier.

A couple of M6 socket cap hex screws from a broken office chair, the head is grooved so I can tighten the screws by hand a couple of times, but I have to use the hex key sometimes because of the next items.

A couple of this weird (for me) screw nuts, with what looks and works pretty much as a lock on, metallic, this nuts came from a motorcycle windshield and hold the screws tight, after a couple of setups I can’t tighten the screws by hand any more hehe.

A scrap piece of 3mm aluminum plate, leftover from some of my electronic projects panels, just had to cut it to match height :)

And that’s it, a couple of hours at the computer to size the design according to the parts I had and at the table saw, at the ruter and at the drill press and it was done…

Actually it took me like a day because just when I was about to do the last couple of router cuts, power went down and I had to wait til today to continue.

Thanks for watching!

Really cool! I love those hexbolts, gives it a cool touch together with the alu.
So well done, I almost feel like making another!
Thank you for the words, that was kind of you.
I’ll soon post some gauges so I can keep you buisy, but for now you can go with the tennonmaker first.

I must display my ignorance. What is the bolt in the end of the bottom piece used for? Looks like a well made and useful little tool.

Thanks everyone!

mafe: sure, keep’em coming :)

BTKS: that bolt is used to adjust for the table saw blade thickness, mafe explains it all really well over here:

CaptainAhab: you made a nice one too!

ratchet: I made a hole to press in a nut into the wood for each bolt, you can see them on the last photo.

Nut hole is a compound hole? 3/8” to hold the nut, 1/2” for the nut base and the pilot hole for the bolt, the nuts I used are similar to this one:

As it turns out if you drill a pilot hole slightly smaller than the bolt diameter, the metric thread on this bolts makes a nice thread into the wood and holds down really well, probably I could get away with it without using the nuts, but I had made the holes for them already hehe.
