I'm gladly here to show you my german equatorial mount homemade, totaly motorized and controlled by computer with PicGoTo system. It was necessary two years for me to construct it, after a long time on project's table and some prototypes, finally, I was able to finish it.
I believe this mount may be more robust than a EQ-5, at least, was projected to be. Here in pictures, it is supporting a refractor with Jaerger's objective (83mm F/12) constructed by me too. But, it will work with a newtonian reflector 6" f/5 and a refractor 3.5" F/5.5 for auto guiding.
