Introduction: K'nex Winch
I made this winch a while ago but have not posted it until now. If you hold it down it can lift or pull heavy things.
Step 1:
This is the base and one of the walls that will hold the handle.
Step 2:
This is the axle which will hold the handle.
Step 3:
This is the handle.
Step 4:
This part makes sure that your load will not fall. To pull the string backwards push the metallic blue clip and the green connector down.
Step 5:
Put the top on and make sure that the rubber band is pulling the white rod down and you're done.
