    This is a print ready chain hoist capable of 30lbs or more (30lbs is all I had on hand to test with). 8x16x4 Ball Bearings, #10 Ball Chain and 3 different M3 screws are required to make this function. Video: http://vimeo.com/42907056 The system has a 3 stage reduction. They are as follows: Drive 2 to Drive 1: 27:9 or 3:1 Final Drive to Drive 3: 27:9 or 3:1 Doubler Pulley: 2:1 For a total reduction of 18:1 Purpose of this thing: I was bored and had a few bearings sitting around so I decided to see how much I could lift using plastic.
