Thanks for the tips Adam, and again for your help.
I’ve attached my “working” version, the joint connections are slightly different that what you had, and I’m not even sure how I finally arrived at it!
This joint system is quite interesting and powerful, but oh so mind bending to figure out!
I noticed in one of the files you sent me that there were no “bones”, that somehow the IK Tag was on the actual object Geometry. Not sure if you could explain how you managed that, not sure I’m ready to try to figure that out either!
