I'm trying to build mobile fences for my Kapex that use the Incra Flip Fence. Considering they are sold in 52" lengths anyway.. and I wanted just over 96".. making each "wing" in two parts makes sense.
I figure if I inlay T-track into the ends of the wing I can quickly (accurately) put them together to make a 104" fence.
Ben, You could build your own rail connector based on a recent posting here on the fog (2 part design)... I might do that after you brought up the question although the Incra bracket works very well to connect 2 rails as well attach them to a base.
