I found this instruction video on YouTube and I thought, “Why not?”

I modified the stop configuration on the movable fence – using the saw to place a notch at 3/8″ instead of drilling hole for dowels as shown in the Box Joint Fence video.
A 3/8″ square guide piece runs the length of the dado sled, held firmly in place with a wooden chock.
Using the 3/8″ guide and two lengths of scrap 1 x 2, I made a 1 x 4 with finger joints! Easy peasy.
Table Saw Note: My Ryobi model BTS10 is probably not the ideal platform for use as a dado saw .
The arbor is 5/8″ so the Freud SD200 blades fit.
However, the length of the arbor and the width of the throat plate limited the dado stack I could use with this saw to just 3/8″ of the SD200′s 7/8″ potential.
