Thanks Stan. Just for giggles, when I have a chance, I will get a TO-120 from my buddy (he does not have a TO-125) and see how that works.
And again, he has put the gate designs aside while he is printing a bridge for the redesigned turntable that uses a lazy susan and slipring combo with a 22" disc we cut out using a router mounted on a swing arm. When he gets back to gates and comes up with a housing for the cross-track and one=side track sensors, I will post.
