We got our jacks.
The motor for the Heavy Duty model is the same motor as used last year. The gearbox is plastic, but heavy looking. Inside, there is a second steel cluster gear which is quite useful. It has 80 teeth mating with the 16 tooth gear from the first cluster. This cluster comes apart, and if you discard the clutch mechanism, you'll find that the 80 tooth gear has a 5/8" hole in it! This results in a reduction of 24.4 to 1 from the motor and a free speed of 225 RPM! It appears that we can use this to good advantage. |
