I used a torque wrench to find the starting torque. It took 250" lbs to initiate any movement of the load. I measured the max torque on my drill motor and it was approx. 150" lbs with a fully charged battery. It seems that a four to one ratio should be sufficient but you may know additional...

Based on what you all are saying, could my problem be the difference in the sprocket diameters and the total number and size of the gear teeth compared to the chain sprocket? If that is probably the cause I will buy a new pair of gears closer related to the chain drive. The load is lifted with...

I did reverse the direction of the motor for the geared unit, if I get it to work I will install an intremediate gear. System Theory you are above my head on that one I do know both units are starting from a standing state.

I can turn the geared drive freely with my fingers using my other hand to apply a load

I am trying to lift a load with a drill motor. I have a chain drive with a 3.7x1 ratio - 13 teeth on the drive gear with a 2.5" diameter and 48 teeth on the driven gear with a 7.75" diameter. It lifts the load easily. I also have a geared drive (no chain) with a 4.0x1 ratio - 16 teeth on...
