It happened like this......I was back in New Zealand on vacation and someone picked up on the fact that - despite the bona fide accent - I wasn't local.
This one takes a motor rotating at 212 rpm and via a series of 50:1 reduction gear sets (12 in all) reduces the final drive output to 1 rp2,000,000,000,000 years.
The output drive shaft is attached to a concrete block.
