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.
