Re: planetary gear questions
Practical? that depends entirely one how much torque and how many rpm's you want to get out of it.

Theoretically, one could stack 10 stages up if they wanted a very slow rpm or a very large amount of torque. However this would make the total reduction 3.67*3.67*3.67*...*3.67 or 3.67^10 which come out to a total reduction of 443262:1, which at no efficiency loss with a CIM would result in about 1 rotation every 1.5 hours... Something tells me this is a little bit more than your looking for.

As for your tube lifting mechanism, I can't help much since I don't know the load on the motor, the efficiency of your mechanism or what motor your looking to use. If you can tell us more about your design, I'm sure that there are plenty of people here who would be happy to go over the math with you (myself included).
