The biggest challenge is achieving the perfect balance of tension.
The Goal: The cord should be just tight enough so it does not sag.
The Danger: There is a tendency to pull the cords too tight. If one cord is over-tensioned, it will cause previously tied bands to lose their tension and sag.
The Method: Do not use one continuous rope. Instead, use several individual pieces of cord and knot them directly at the holes.
Step 1: Preparing the Cords
Each connection starts at one of the 4 "star structures" (a center hole surrounded by 5 arm holes).
Cut a piece of cord.
Length: It must cover the star pattern + the distance to the other head + extra length for the knots.
Step 2: Knotting the Star (Head A)
Start at the center hole of a star. Lead the cord from the inside to the outside.
Connect 4 of the 5 arms of the star one after another: Thread the cord through an arm hole and always lead it back through the center hole.
Important: One arm must remain free. This arm will be used later by a cord coming from the opposite head.
After the final pass through the center hole, tie a knot. The friction should already be enough to hold the cord in place.
Step 3: Crossing Over (Head B)
Take the free end of the cord and lead it to the opposite head half.
Thread it through the free (5th) arm hole of a star there.
Lead the cord from that arm hole to the center hole of that star, then back to the arm hole, and tie a knot behind it.
Crucial: Check the tension as described above before tightening the knot! It should be straight but not pulled tight.
Step 4: Repetition and Extra Connections
Once all 4 stars are connected, you can add additional lines for visual effect.
If the center holes are crowded, use the arm holes.
Example (Loops): Thread a cord through an arm hole, lead it along the outside of the head to an opposite hole, and knot it. Hide the knot behind the hole.
Step 5: Balancing
Before removing the wooden jig (support frame), double-check all cords. None should sag.
Teamwork: This step requires 3 people. One person unscrews the jig while two people hold the head halves.
Finding Equilibrium: Initially, one half will want to tip over and pull the other with it. Gently find the point where both halves balance each other, held only by the cords and the barrier of the base plate.
Protection: Re-attach the wooden frame during the rest of the exhibition setup (or overnight) to prevent accidents.
Safety Notes
Vibration Sensitivity: The balance is delicate. The pedestal must be as stable as possible, ideally bolted to the floor or weighted from the inside.
Risk of Destruction: If a visitor bumps into the sculpture or if the floor vibrates heavily, the heads could fall and shatter. Ensure the floor does not swing or vibrate.
