Homemade capstan

I needed to bring flat rocks from a creek bed and logs from a gorge at a friends house. We can not get a vehicle in so we decided to string a 250 foot steel cable and pull up the rocks and logs using a trolley and pull rope. It's a 40 degree incline so we need a capstan to pull the 200+ feet of rope. I could not afford the $600 and up for a commercial capstan, so I made one for about $150. The biggest expense was the 2.5 HP motor for $80 and the reduction gear which was $40. The pulleys were purchased for $20. The rest was made from bedframes, exercise machine, toilet flange, and misc. steel I had laying around. This was my first real test of the system and it seems to work fine. Had fun making it!
