Thanks in advance.

A great tool to go through this is JVN's Design Calculator ( http://www.chiefdelphi.com/media/papers/2059? ). It has all the motor data and you can input gear ratios and it will calculate the output torque and everything you need to know. Coupled with the math provided above, you can quickly figure out the ratios you're going to want for your lifter. I would suggest when inputting gear ratios to use gears that are available from AndyMark (or whichever supplier you prefer) so you're not having to make your own gears.

Also, if you need more help, feel free to PM me. Our team is in the final stages of our off-season hanging design that uses the vertical pole, so we've gone through the math involved.

Edit: I just realized, you're from Fremont, so we're ~30 miles away from you. If you'd like, you could come down to San Jose, and we could help you through the whole design process
