Make strong and elegant miters.

This innovative jig slides easily in your router table's miter slot, and clamps the workpiece tightly between two adjustable (and removable for larger boxes) support fences. Rout slots with dovetail, straight or straight spiral bits, then make a spline to glue into each slot, creating a strong miter joint. The splines add a finished look to your project when you make them out of contrasting wood.

  • The jig is made from 1/2" thick, melamine coated MDF and has a 14-1/2" long aluminum miter bar that will fit any standard 3/4" wide miter slot
  • The aluminum miter bar position is adjustable using the mounting slots provided in the base and will work with tables that have the center of the miter slot 5-1/2" to 8-1/4" from the center of the bit opening in the router tabletop
  • The base is 15-1/2" wide and 10" deep. The two adjustable support fences clamp your project tightly, when cutting the splines across the corners. The vertical handles allow you to safely hold the jig on the router table during use, keeping your hands well away from the sharp cutting blades of the router bit.
  • We recommend dovetail, straight, and solid carbide straight router bits to cut the spline.

    Just OK (3/5), Jan 8, 2019

    By Ed Lawrence (Gloucester VA US)

    Not what I had hoped for. In using the jig, I notice my box was unstable and discovered that the bed was not a true 90 degrees. It was out by about .017" which is too much. Using a double fold of turners tape solves the immediate problem but I can see that a more permanent solution is in the future.
    Frankly, for the price, it should be bang on.

    The laminate was peeling right out of the box. Easy to put together. Will work with it soon.

    Received it yesterday and it seems to be well made.EZ to assembly. I think its going to be an excellent addition to my tool & jig accessories. Hope to be on a product and use it in a few days.

    I just received the #9538 router table spline jig for birthday gift from my dad. Put it all together and started to pick it up with both hands, because it's fairly heavy, and part number " E " had the little embedded anchors pull right out . I am guessing those parts should be made out of real wood, as the MDF isn't strong enough. I will make new ones out of a nice piece of BIRCH.
