Cast transformation from one actor to another actor

I’m struggling with this:
[video]- YouTube
The silver arm (of a lifting station) is stuttering because the gold fixing and the silver arm are separate actors. The fixing performs the animation (so its fluent), and casts the location to the arm (which is stuttering).

I hope there is a way to avoid this…
Thanks.

passing transforms will have lag, anyway, so try to use attachments instead.
