Tried making two Spline Jigs today and this was the winner. The first was in a sled form and it wasn’t producing a clean (even) cut. Thing my angle was off a bit. THis one is easier to use and dead accurate. Now on to create a box.

Yup, and very small form factor, easy to store. I’m copying that sooner than later!

Looks great. do you have any issues with the box coming off the jig during a cut? Doesn’t look like a lot of support for the piece as it is pushed through.

Jarod, I haven’t had an issue yet. Althought the support pieces are only 1/4” (purposly made them thin for use with smaller boxes so the blade wouldnt make contact with the jig) when the box is clamped onto the jig, there is no movement with an A+ cut.

I would tape the back side of the cuts or clamp a backer board on to prevent tearout as it is hard to hide when it occurs! (don’t ask how I learned this)

Tmac – You answered my first question in advance. Second one coming at you. Does it slide over the fence? That is unlitmately very clever. Even I could make one of those. Thanks so much for posting!.

-- Thanks for all the lessons!

Yes Mark, sits right over top of the fence and slides along the length of it.

Box is in progress Exel. Soon as it’s complete will post box with jig again. It is a black walnut box with maple splines. Looking good so far.
