Well, I got it going, what a project... Lot of little details that seem like they took all day to iron out, oh wait, it DID take all day!
Don't remember if I posted this one, this was the FIRST location of the servo.
I wasn't happy with that spot. It hid the center mounting screw and was in the way for other reasons.
So, I moved it back to where the potential second servo was going to go.
Here is a shot of the center hole mod to allow the wire up the center instead of my initial plan of the kidney holes. Had to drill the center of a 8-24 rod and then drill and tap the center hole on the crane body. Won't be able to spin but good enough, just need to keep the revs down to about 1 each way. There was no way an audio jack was going to fit, I bought some 1/8 sets at radio shack and it just was to tight to get that to work.
And here is a short bench test. I had it on the loading wall, but it got cold an rainy again so no job site video today.
