Ah, sorry, I was confused! Need to learn to read
Their plastic chain has a spacing of 0.1227, so I thought you meant this.

""""
Turns out the #25 chain I am using has a smaller roller diameter (.120) than they use (.127) which would explain why my chain binds up when you wrap it around more than 100 degrees or so. They are sending me some of there #25 chain to rectify this.
""""

But what you wrote is that it's the diameter of the rollers that is different. Never heard that before.
However, using a chain with smaller roller diameter on a sprocket designed for a larger diameter should work, I would guess. (Never tried it, though.)

Thanks for the heads-up, will have to remember this...

Got a little more done. The chain drive for the rotates is finished. I maybe over engineered it but, I wanted it to be strong so that I could push dirt sideways with the bucket on occasion and not worry about anything breaking.

This may be a silly question but what are the black wire leads going into the track frames? Are the drive batteries between the rails?
It sure works well on rotation and looks to have a good speed on the tracks
