Work In Progress: MoCo Dolly

The (loosely) assembled carriage and tail bearing, with limit switches installed and wired in. The wiring runs through the slide rails (which are hollow) and out through concealed mouseholes in the underside of the tail bearing block...all neatly tucked away.

The contact rollers on the limit switches can be seen peeking just past the switch brackets. It may look like the carriage would crash before actuating the switches, but it reliably contacts both switches and stops with about 1/16" to spare at either end.
