I have changed the layout slightly, and I will be including a double bottom. I will also be including a double fence but it will not have an anchored fulcrum. Instead it will have 4 spring loaded adjustable knobs. I am waiting on “T” tracks to arrive that will be routered in for the 45 deg framing feature. And a piece of track for the top of the fence that will hold a sliding clamp and stops all from Lee Valley. For now here’s some updated pics of the overall layout. The top piece of the floating bottom is in small pieces of 1/2" ply right now but it will be almost the same size of the 3/4" bottom, just 1/4" shorter to allow for adjustment knobs to move the fence/bottom to float.
