There are 3 different versions, made by Makita, Ryobi, and Hitachi. All of them use the same style with 4 blades. There's a video of one in action here. That tenon cutter would sure speeds things up, and if you have a trolley for moving the timbers around, or lay the beams out on a deck, set to the same height as the clamp you would be able to motor through the cuts. THANK YOU FOR YOUR TIME !
