I used the horizontal table on my new-to-me 4x6 and was shall we say, less than overwhelmed by its quality and function.
I'll definitely be borrowing your ideas if I may. Would you be willing to share your CAD file
Nice setup. I keep meaning to do something better with my HF saw. I found a article about using a hinge in the large plate, allowing you to fold it away when you want to do horizontal cuts. Can't remember where now though..
