I'm not sure if this has been posted here. I didn't see it in the Tutorial section.

Mine works pretty good, I still have to move the kerf with the handle, but its automatic. How do you put in a tute ? I may do my circle cutter If my guy sells me some old plane parts here.... gaah

Appologies to anyone happily using one of these, but every time I see it, I think "Rube Goldberg" (designer of famously, ridiculously complex machinery for doing simple things). If you want to be famous for building jigs, fine. I index just as fast or faster using an offset brad (see "reverse-kerf lining" tutorial under the "archived OLF tutorials" if you want to have a look.)

I think it's pretty cool and when I see something like this I take away the design elements and then maybe in the future I can use those designs in some another way on some another type of jigs. It's like where someone took a motor and a shaft like an old train engine drive wheel and the thing is totally automatic. Do you guys drive an automatic or stick shift? Do you use routers or cut your binding channels by hand? Why are you putting down an idea because it's not the way you like to do it?

This is the coolest jig ever! Its not that complex, and its brainless. Chink, boink, chink, boink....Like im a kerfin machine....Somple to build.... And cuts kerfling for a geetar in a few minutes. bliss

Have you thought about making the fence higher so you could slot a 3"-3 1/2" piece at a time and cut it later?

Thats another good idea...thats a crazy idea....but my wood is usually 1" stock....

Post subject:  Re: Kerf Cutting Jig

As I mention in the Ksled tutorial, I think the original design concept for this jig was Frank Ford's. If you examine the jig carefully you will discover it really only comprises a striker arm hitting an angled depth stop the action of which progresses the stock across a fence in equal increments. The jig fulfills this function with infinite adjustability for both depth of cut, and distance between kerf at a speed of operation only limited by how fast one can slide it a short distance back and forth along the mitre slot in their bandsaw table.

Nothing overly 'complicated' about that, just accurate and exceedingly efficient as one would expect from a Frank Ford idea.

Cheers

Sorry Chris if my comment may have sounded 'Mario-ish'. I didn't meant to sound harsh.

I'm not putting down the jig because I prefer to use another method, I just feel that deciding to make such a jig to make kerfed linings is making your life more complicated. Although it looks cool, simpler methods will give you the same results.

The 'brad bit' technique may be the same thing but would it work for triangularish kerfling>? I done tink soooo.... :cry:

Post subject:  Re: Kerf Cutting Jig

Very cool, but...

Stack 2 or 3 little Diablos with spacers on the table saw, sketch a spacing mark on the table or your miter guage, and go to town. I make my pieces double wide, radius, kerf, and then rip to width.

I don't know about you, but anything that makes an operation so easy its "brainless" always gets me into trouble....

Post subject:  Re: Kerf Cutting Jig

I think it's a pretty slick jig. I made one a while back. It cuts the kerf the same depth each time and automatically moves the piece the same amount after each cut. Just push it forward and pull it back, even I can do it.

Now, if I would just take the time to rip a bunch of mahogany strips and put the radius on them...

Far from it and I'm sorry if I sounded like wise. :) I think that I'm just getting bombared with so much negitive news and statements these days that I just can't take it anymore. I just hope it doesn't creep it's downer head into this forum, if you know what I mean.

Not sure how deciding to spend a relaxed afternoon in the workshop having a bit of fun knocking up a cool little jig out of scrap that will amaze your friends, and produce excellent kerfed linings of any profile quickly and accurately for the rest of your days as a builder, qualifies as something likely to make ones life more complicated Alain. It certainly did not have that affect on mine, in fact I may even make another one just for the heck of it and this time do a bit of inlay work to spruce it up a bit :D

I wanted to echo what Chris was saying. Sometimes I look at a jig that someone has engineered and I'm not quite sure why they did it that way but I find some jewel in there that I can adapt to my own need. Thank god we are all so different or we'd all be building the same guitar over and over. Nice save on the almost crankiness by the way, everyone.

Post subject:  Re: Kerf Cutting Jig

I used to use a dovetail saw and box to cut the slots in linings. It was slow and time consuming but it worked. Then I made a fence for my band saw with an indexing pin. It was much faster and less tiresome than cutting by hand.

In the meantime I had been looking at Mr. Fords site at the little kerfing sled he had made some years before. It took about a year before I decided to make one to see if it would work. So I blew up a photo of it so I could get a good look at it and decided I was just going to use what ever I had in my scrap bin and junk drawer to build it.

It took all of about an hour and a half to cut it out and put it together, and it worked, but not too smooth. But after seeing how it worked and understood what it done, I added this and moved that and in a few minutes, it was making kerfed linings.

This is all I use now to make my linings. Sometimes I like to use the same type wood for linings as the body is built from. Or maybe I like to laminate some different colored woods together and use this for linings, just cause to me it looks good. I also use the K-sled to make Reverse Kerfed, Triangle linings or Straight linings. I always have narrow strips left when cutting up boards so they don't go to waste. If someone comes by and needs some linings I can just give them a handful cause they cost next to nothing for me to make.

So, If one prefers to buy their linings I think that is OK. If one chooses to make their own using a table saw, band saw, hand saw, Fork, Knife, Spoon or Rock, then that is OK too. But don't knock what someone else chooses to use or do unless it will cause a Nuclear Meltdown, a Tsunami or a World Wide Catastrophe.

I must confess Daniel, I do find myself glancing sideways at the Ksled when entering the work shop. That little booger is 'far' too efficient at what it does to be trusted...today kerfed linings, tomorrow the world! :twisted: :)

Truth is Daniel that many of us remain very grateful to you for nutting this out from Frank's site and sharing. Your efforts are what made my tutorial possible and I have had quite a bit of positive feedback about the jig since it was first hosted a few years back.

Cheers and thanks mate. [:Y:]

If you're going to knock up another on I'll take it off yer hands Kim, with or without the inlay.

Perhaps I can persuade you with some sets of primo Tiger Myrtle I have drying at the moment.

It's one of the slickest jigs I've seen in a long while.

Post subject:  Re: Kerf Cutting Jig

Indeed, this is a cool jig. And I'm sure it was fun to make. Nevertheless, I still think that there are simpler and faster ways to make linings.

I should be making some within the next two weeks. I'll take pictures of my setting and put them here.

Thanks Kim,
The only reason I ever posted about this thing was I thought it would be of use to someone that wanted to take the time to build it. As I said, I looked at this thing on Frets.com several times before I decided to build one. I kept thinking it looked a little strange and probably wouldn't work very well. But it does work very well, and I'm glad I took the time to make one.
Thank You Mr. Ford.


Alain, Don't take my post the wrong way. To ME this is the easiest way to make linings but I am looking forward to seeing your way of doing it. If I think that yours is the easiest, most accurate way then I hope you wont mind if I use your method.

Thanks...Daniel

Post subject:  Re: Kerf Cutting Jig

Well I printed it out and I'm going to use it somewhere in some form or I just might build one just for a conversation piece when someone comes to the shop along with my funky clothes pin bean pliers. :mrgreen:

Yeah, it's been posted before, and it is a nice little jig.

Todd... maybe you could post some photos of your variation of the K-Sled. As adept as you are in building jigs and tools I am sure that you have made improvements to it that may help someone in building their own if they wish to do so.

Thanks...Daniel
