[PSUBS-MAILIST] Gear for manipulator

[Alan via Personal_Submersibles]

Hank,
I imagine there will be quite a load on the gears. I want to lift as much
as I can, at a reasonable speed, with the power available in those two
different motors. 
There is a bit of compromise here as I am powering it with an off the shelf
item & was hoping there was a suitable gearbox about that would get
me in the ballpark. 
I have ideas of putting a camera on the wrist & using the manipulator as 
a snorkel; so it will be reasonably long.
Just finished my latest motor housing, (which took a long time) so 
trying to avoid more hard work lol.
Alan
