These homemade pulleys work great as long as they glide freely over the coat hanger wire (meaning that if you give them a spin, they keep spinning for a few more seconds).  You can adjust the amount of friction in the pulley by adjusting the where the metal wire bends after it emerges from the pulley.

  1. You can use the hook at the top to set it in place, then throw a rope around the spool, and you have a pulley! What you do with it it totally up to you. My kids used theirs in the tree house in the backyard and connected the other end in the house for me to put pancakes in on Sunday mornings so they could breakfast outside without going up and down the ladder. It had a little basket attached to the rope, and the pulley was attached to the tree house rail.

    Do you have information somewhere on what you do with this coathanger pully after you build it? How do you rig it to be used as a pully?

    Thanks

    Hi Aurora,

    Thank you so much for all of the work you’ve put into this course. I am new and still learning my way around. Where do I find the directions for the cool pully that you are holding in your hand in the video?

    Thank you,

    Javette
