I was out in the workshop this evening making a simple box. I mitred the box and needed to spline the corners. I made this simple jig to aide in creating a grove for the spline.
It’s a 45 degree “rest” for the mitred board to sit on as you slide it over the blade.
Here is a pic of a test board on the jig. The jig is placed the width of the mitre away from the fence. If you have a gap under your fence like we do, you will need to add a piece of material, (we used MDF) to your fence. Anything will do, as long as it covers the little gap.
Next, the jig is held to the table with MagSwitch magnets. We used 2. Could use clamps, but MagSwitch is hard to beat.
With the jig in place, turn on your saw and slide your board through. Super easy.
Here is the result
Insert your spline and your golden.
There you go.
