Add flair to the mitered corners of your box or frame projects—and strengthen the joints in the process—with our Deluxe Spline Jig! It features an aluminum miter bar that fits standard 3/4” x 3/8” miter slots and a sled that holds your workpiece at a 45° angle as you guide it smoothly through the cutter. Unlike other spline jigs on the market, our design lets you adjust the jig to suit a wide range of spacing between the center of the miter slot and the center of the cutter. This flexibility lets you use the jig on both your table saw and router table for expanded versatility. The jig’s adjustable fences act as stops to position your workpiece—one setting can cut all four slots for a frame or eight slots for a box.
Here’s a chance to explore many creative joint-making possibilities! You can produce different spline geometries with various router bits—straight, V-groove, dovetail and more. Try a combination of square and tilted table saw kerfs for a different distinctive effect. Or mix and match router bit cuts with saw kerfs to mill patterns that would be impossible with other spline jigs!
Rockler Deluxe Spline Jig Details:
- Holds boxes or frames at 45° while you guide them past the saw blade or router bit to cut slots or dovetails in corners for decorative, joint-reinforcing splines
- Works on both table saws and router tables with standard 3/4” x 3/8” miter slots that are between 4-1/4” and 7-5/8” from the center of cut
