Kerfmaker
So now it was my turn to come up with an attempt on the Kerfmaker…

Another fun gadget is the tenonmarker:
http://lumberjocks.com/projects/39236

I have been walking like a cat around the milk, when it comes to the Kerfmaker, the original are so dam cool, and well made - here on LJ there are so many fine attempts to make the same thing - and I did not want to copy the original…
But the final push came the other day, when PaBulls Kerfmaker was posted. I liked the fact that he put the locking mechanism on top, in that way it can be turned in all directions like the original.
Thank you for waking me up!

And I just 10.10.2010 see that ChrisinOttawa made one long before in the same princip and really cool (I even commented at that time), so I will give him the credit for the design, and PaBull for the push.
All I did was to make my version.

So my contribution 'BRASS'!

I was not happy for the change of grain in the front, so I decided to make a front of brass, and then the rest simply happened. I mounted a threaded rod in the bottom, made a washer from a Euro Cent, mounted a threaded insert in the back (deep inside), so I could use a brass finger screw to set the blade thickness without tools and yes put a little brass rod in the top back, not just for fancy looks, but also so it would be a clear zero when it becomes a little worn.
Measure: 15×3,5×1,75 cm. Max wood 8,8 cm wide.
I changed up and down from my inspiration, so I would have a long rail all the way to the end. (Brass parts were mounted with Epoxy and a little brass screw in the front).

At first try, I adjusted the sawblade finger screw, set the Kerfmaker for the wood size, and made the cuts, then cleaned with the sawblade (as you can see in second last picture), no nothing after, just left it as it - and it fit perfectly! So I was a big smile once again!!!

I also made another kerfmaker the Kerfmafe handydandy, and a Blog on how to use a kerfmaker, hope it can be usefull to those of you who are full of questions on this.

You might be interested in my Height-, length gauge, when you have to set the table saw depth for the cut.

Hope it can be to some inspiration,

Best thoughts and thank you to all here who inspire me,

Good job. A touch of class with the brass. I could really use one of these. If only I had a Euro cent, I would make one. :)

Mad, you proved right, I like your execution of the Kerfmaker. Not bad for an architect. I was trying to use material that was just laying around. (The Dutch in me)

And thanks for the mention!

I like it!!!

I agree that Simon was a great inspiration with respect to simplifying the overall design. Great job.

Nice work!

I must admit, I don't see how turning the knurled knob/thread would move it. If you loosen the top knob, it seems the slider would move regardless of the threaded insert. Unless it attaches to the moving part?

Really nicely done Mafe.

RonPeters the knurled knob that runs parallel to the length is to make fine adjustments based on the blade thickness. It does not change the opening created by adjusting the knob that runs at a right angle to the length. The two adjustments are independent of each other.

Beautiful piece mafe. You've inspired me to try and make one. I promise all LJ's not to post it though. Word. ;-)

Love it Mafe, it is really beautiful.
I had some exotic hardwood scraps and made a small one for box inserts.
Used a rare earth magnet inset on one internal side and metal rod on the opposing side so it holds together like magic with no bolts or wing-nuts, but can slide along.
It was an adventure in overcoming multiple screw ups I made….there was no room for a bolt/wing-nut to fit as the stock was too small

Very simple and effective. Well done.

Has anyone tried to figure out a way to make one of these that will work when cutting with a dado set or possibly with a router bit on router table? I would think it would just be a matter of making a different way of compensating for the blade thickness. I may have to see what I can come up with.

nice work mads :)
that was the problem I saw with most kerfmakers, the fact that the securing screw protruded and you couldnt lay it down flat on one side.
i'm a big fan of brass myself. i'll show you some things i've turned. wont post any of them here cause this isnt a metal forum ;)

Hi,
PaBull, yes the fact that I'm a Architect considered, it actually works! I laugh, guess you have had some of the deficult model of this proffesion close on hand in your past. And thank you again.
And my stuff was also just laying arround… Just have some boxes from my knifemaking, and the bolt's are from Paris where I bought me a good bag of these knurled bolts and nuts. The wood are a old table leg, found in the street.
Jamie, you speak Danish now! What's happening - thank you for your mail. Remember to post.
docholladay, this one can be used on the router or with a dadoset, it's why I put the bolt in the back, with the threaded insert, in this way I have up to 17 mm of adjustment, and this can be made as big as you want, just by using a longer bolt and a deeper hole.
Scott, will it not move then, or could you make it so strong? Clever idea.
Chip, you have to post it, it's what LJ are all about, we inspire eachother, just by the little changes we make.
Ron Peters, Swirt has got it.
Cranesgonewild, yes it would not be the same with out! So you better give up!
Steve, yes some people solve the problems, and some people make them… LOL.
Flemming, it was also this side screw that was bothering me (mostely for the design). You can post it as a forum topit, I think this is 'allowed', otherwise PM me.
Now I'll be in peace with the kerfmaker untill some one get a new wonderful idea here,
To all of you - thank you a lot,
best thoughts,
Mads

One classy tool my friend! I am so impressed and you keep inspiring us all. The wood looks like Mahogany?

Can't you design a tool that will extend the amount of hours in a day?

I'm always late on your posts. It seems our surf habits don't coincide and you post just after I've gone to bed! Doesn't matter though.
I only LJ at night, otherwise I will never get my work done!
