Thanks for the replies.
Yeah chain and binders aren't cheap at all, especially good ones. The binder is a Lebus.
I am concerned that as the mill moves around the chain may loosen and let go on me because of the give that the spring allows. I am considering cutting the spring off and using a double clevis to attach the hook.
I always take a wrap around the binder handle. A hold over from my old days driving truck.
