Introduction: Simple Pulley System
My machine is a minatur pulley system.e
Supplies
Small pieces of wood
Twine (1.5-2 feet)
Cardboard
Super glue
Step 1:
Glue the wood to make a rectangle
Then glue another piece on the bottom so it can stand on its own
Glue two longer pieces of wood standing up on the edge of the rectangle and one sticking out from the top making an L shape.
Then drill a small hole on the far right for the handle, make it around a half centimeter wide
Step 2:
Cut small circles of cardboard
Roll a thin piece of cardboard tightly so it’s about as wide as a pencil
Cut the rolled cardboard into half inch pieces
Make three
Glue the rolled cardboard into the middle of the cut circles It should look something like this:
Step 3:
Glue all three pieces on three corners
Step 4:
Roll up a longer piece of of thin cardboard so it’s about two inches long and two smaller half inch pieces
Glue them in the shape above
Stick the long end into the drilled whole
Step 5:
Glue one end of the string on the side next to the handle and rap it tightly
Make a little bucket out of rolled cardboard and tie it to the other end of the string
Wrap the string around the three pulleys so the bucket is hanging
