Box ( Finger joint) jig for a router table

After tons of research online and help from my LJ's buddies I designed my own box joint jig for a router table without a sliding mortise track..

This project took much longer than I thought because of the minute adjustments I had to make in the jigs final position and secure the cleat.. But it's done and the fingers are a little loose but they fit together like a dream with just enough real estate to glue up a joint...

The basic design is " L" form with a cleat that overhangs the table to slide it though the straight bit.

I had some leftover poplar so I used that and I also had 1/2" square dowel left so I used that as the key...

Because I cut a Chanel all the though the jig I supported the back with some scrap plywood L brackets held together with glue and pocket joinery ... And the back of the jig where the channel comes out of the jig I placed a scrap piece of plywood to keep the jig square to the table and cutting bit...

I'm delighted with the results and it didn't cost me much
