Parachute Man Pulley Launch System

Step 7Top Pulley

Top Pulley
We used a step ladder and screwed a hook into the beam and hooked a pulley over the hook.
This pulley has no sides or "cheekpieces".
The cord can fall off the side of the pulley, jam up and stop running smoothly.
Get the cheekpiece kind of pulley.

We didn't put a pulley at the lower end of the loop. We just put a loop of string through it and tied that to a cabinet in th other room. That keeps the loop from hanging down in the middle of the room and getting in the way.

The loop has to be loose while hoisting or the clothespin will open prematurely.

enjoy!
