I’ve just finished installing the remaining servos and aligning them. My biggest problem was how to mount the servos when they are close to a support timber under the table. I spent some considerable time looking around the internet at other people’s solutions and finally came up with this one. It employs a right angle bend and one of the other holes in the servo holder. I added a wavy “spring” section since there will be a twisting force at the right angle bend. The wire is bent underneath the actuating arm to hold it in place.
The next task is to wire up all the micro switches to power the frogs. I’ll get onto soldering these later.
