Pool Lift Model

Requires (4) M5x25mm screws (20mm will also work), (4) M5 nuts, and a rubber band.

Assembling the mock hydraulic cylinder:

1. Thread the rubber band through the inner cylinder (the piece that looks like a little top hat) so a little bit of the rubber band pokes out of the end. Use a bread tie as a threader if necessary.
2. Insert the end without the brim into the wide hole on the outer cylinder.
3. Thread the end of the rubber band coming out of the outer cylinder onto the hook on member ABC.
4. Pull the rest of the rubber band through the inner cylinder and loop it around the hook on member BE.
