« Part 1: Router Sled Part 2 of My Shop series Part 3: Dust Collection »

There has been much discussion on the Bridge City Kerfmaker, but I didn’t find where it was used on a table saw without using a sled with a stop. I am sure I just missed it, but here is my version of the set-up.

The Kerfmaker references off a stop on a fence, which works very well for a fence on a radial arm saw or table saw sled. But using the table saw fence to cut slots for my box bottoms and lids, I discovered there was not reference point for the Kerfmaker. I made a simple block using magnets to secure it. There is a lip on the bottom to keep it straight on the table saw rail. I started with 2 magnets, but it didn’t hold as well as I wanted, so I added 2 more. Stronger magnets would work as well, but these were what I had. I tried it with a c-clamp, but if you have checked out my jigs, you know I don’t like messing with c-clamps on my jigs.

Set the fence for the first cut and place the kermaker on the rail and place the stop next to it, carefully keeping it free from chips and squared with the rail. The lip on my block is made to fit between the rail and the saw to help do this. Make the first cut, flip the kerfmaker as usual, move the fence, and make the second cut. Then saw out the waste between as usual. I am not going into detail of using your kerfmaker. If you have one you should know the basics already. That has been covered here on Ljs and on Bridge Ciy’s website.

I think the pictures are self-explanatory, but ask if you have questions.

very cool setup, and like you said, I think this is the first reference to using it with the saw fence for ripping. everywhere else references cross cutting notches.

Nice setup. I think you are the first in using it for ripping. I’ll be using that method in my box class with my Disposable Kerfmaker.

I seem to recall seeing someone who has a video showing it being used in a similar way but one the table top instead of the rail. The stop block used one of those on or off magnet things. If I should have a eureka moment and remember where I saw it I’ll post it.

Nice write up. Good use of magnets.

In our original video, at from 1:28 to 1:40 we do the same thing with the KM-1 used on the table saw rail.

Paul Marcel also has a fantastic video about the Kerfmaker on his blog:

Have fun!

Thanks Michael, I thought I watched your video, but I missed that. Obviously we were on the same track. Thanks

Note: My jig will work the same on either side of the fence, or even on top of the saw like the Half Inch Shy video Michael suggested.

Kent, I like your magnet method.

Interesting accounts ( BridgeCityMike and jjeconomaki ). We are being watched. :)

rance,————I actually invited them to “watch”. I believe it makes good sense for the manufacturers to be in tune with the end users. There are many companies that keep an eye on what we do here.

Thanks to everyone for the positive comments.

There is nothing like a new jig. Great idea Kent.

Great idea!

Now all I have to find are some magnets that will work on my aluminium top!
