One of the first things I did when I got my new saw was build a crosscut sled. I made it a little smaller than most I’ve seen since I do a lot of box work, and I wanted something that would be convenient for smallish pieces. When I decided to do a spline jig, I started thinking about building it in to the crosscut sled, and this is what I came up with.

I had previously built a spline jig similar to ones I had seen in magazines, but I never felt like it offered enough support for the box. This is wide enough to support the entire box. The fence is just a simple piece of wood that can be clamped in place, and the whole contraption is attached to the crosscut sled with two screws. I figure I can leave the spline jig in place and still be able to make 99.9% of the crosscuts I normally do. If I need the extra space, it can be quickly removed by backing out the screws.

All comments and suggestions for refining the idea are welcome.

Nice jig Charlie. Wow using walnut for jigs now? Guess I won’t show any MDF jigs anytime soon.

Thanks for posting it.

Charlie: If you wanted to do three splines close together similiar to Gregt3G box that he posted tonight. How would you do that with your arrangement. Can you post a couple of other pictures being able to do that.

Karson, I haven’t worked with it too much yet, but the way I see it in my head is like this: You set the fence, make the first set of cuts on all four corners, then move the fence the desired amount and make the next set of cuts. In theory, you can make cuts for as many splines as you want. You can also make the cuts for thicker splines by moving the fence just a little to widen the cut.

Nice Jig and great use of dual purpose with crosscut sled. Only comment for improvement I can see is a hand guard for the pass through of the blade when doing cross cuts. Just a thick block or a plywood cap over the kerf would give a lot of protection for your fingers.
Definitely an idea I will be imitating.

Charlie, thanks for posting, been looking for a practical, easy on/off spline jig and the search is over. Please advise when the patent takes effect so I can get my copy made without infringement.

Happy holidays to you and yours

Hey man neat jig! I understand your comment back to Karson, the fence does allow for infinite spacing of splines. I just still don’t understand how you make those corners so square!
Merry Christmas Friend,

Very nice jig dual purpose too…...I see you have a clamp like the ones I have and I stopped using them because I clamp then tight and I turn around and it let go, would you know what makes that

Charlie -

The removable spline jig is a great idea. My spline jig suffers the same support issues you described. I’ll use your idea on my next splined project.

Thanks for all the nice comments.

BTKS, I am planning to add a hold-down clamp so my hands stay out of the sled during cuts. A guard of some sort might not be a bad idea though.

GMan, that’s a Bessey clamp, and I’ve never had the problem you describe.

Woodbutcher: I’ll take that secret to my grave, Ken.

Merry Christmas to all!
