I like that screw drive. looks well made. wish I had seen this before I used a ace hardware threaded rod in my end dump.

I also used tecnobotsonline for a reduction unit on my 1/4 frame. I went with a 50:1 and it lifts a full box of wet sand in about 20 seconds. power comes from a 7 cell battery. You can hear the motor is working to get the box moving but once its a few degrees off the tractor its smooth sailing. your 100:1 should be just fine for the task.


Keep the pics coming!
