speed reduction box with nanotube shafts - update

After 81 hours the simulation is 54% finished. Over the last couple of days there has been some stormy weather here, and that has made me a little nervous. Normally I really like storms and invite their presence, but the thought of losing power, even just for an instant, has me wishing for nothing but sunny skies for the next 80 hours. Otherwise it's three and a third days down the drain.
