David, here are some more pictures. Sorry for the delay..
The sled attaches to the T-slot with two screws. One goes into the same T-nut I use for the crosscut fence, the other goes into a seperate T-nut (bought from Felder). The two aluminum brackets are for locating the sled at the exact same spot every time.
By using aluminum extrusions for the base I have unlimited posibilities to attach jigs.
