My take on a tracksaw guide for my Makita trim router. It may fit other trim routers but I don't own any. Will work on any Makita/Festool-style tracksaw guide. Has a guide slot to line up with the center of your router. You'll need supports for the side that connects to the track guide. I have really good luck making the top interface ~90% concentric. Leaves a better bottom finish. FWIW.
