What must be adjusted to correct out of round circles

Regarding the rotational radius, My hand-built sled measures 119 from the spindle center to the outside of the ring. I do not know how it is calculated from there, but adding the space between the outside of the ring and the end of the chain the pin goes through, I get 14.287. Adding to the 119 = 133.287

This is interesting. See my post in the forum wiki regarding rotational radius of the ring kit and tell me if my meausrements are off. I did it based upon drawings but would love some actual verification. I say it’s interesting because when I calibrated it wants to drop rotational radius to 133 and in under the impression it’s closer to 140…
