Make the slide out of a hard wear resistant wood. Cut to fit without slop and be just proud of the saw table.

I used 1/2" birch plywood cut to 12"x16". You could also use 3/4" or make a difference size for your needs.

Use CA glue and accelerator to glue the slide on. Then remove from the saw and predrill and countersink holes and screw into place.

I used a 1x2 for the three frame sides. I glued and brad nailed them into place. Cut the fence a little long but do not permanently attach it yet.

Remove the blade and install a dado set.

Screw down the fence so you can cut the indexing pin slot.

The slot width will be how wide your finished joints are. The depth of the slot should be a little less than the thickness of the wood you will use. I use a 1/2" dado for 3/4" thick wood.

Remove the fence. Now cut indexing pin material to fit tight in the slot in the fence. I used oak for wear resistance.

Now install the fence offset from the blade by that distance as the width of the indexing pin. You can use some of your extra indexing pin material to do this. Now permanently glue and screw the fence in place while the slides are still in the miter slots so it doesn't move.

Now wax the slides and base to allow the jig to move smoothly on the table.

Test using a scrap piece. Start with first piece butted up against the indexing pin and work your way over. Not flip that piece over and put it back over the indexing pin as a reference for the mating piece. Work your way across the mating piece until its complete. Test the joint. If it fits properly, you can glue it together to make it permanent.
