This is my new gearbox, the gear ratio is 160:1 when I say that you won't believe what it can do, I mean it.
Update: I had assumed that the markings on my anvil (1.2.0) was the weight of the anvil, but a comment got me to investigate further. Apparently the anvil weighs about 168 LBS. So this gearbox actually lifted over 300 LBS.
Check out my previous video if you would like a little more info on this project!
