Very good, Ken.

If you don't mind, I'd like to distribute it to our younger team members, as it provides a clear, concise explanation of a lot of what I'd like them to know - and in a better way than I could ever do it.

The only point of confusion for me was regarding the efficiencies of different methods of transfering mechanical power . . .

Quote:
Power Lost for each stage of different small parts:
Spur Gears: 90-95%
Worm Gear: 10-60%
Nut on a Tread (not ball nut): 10-60%
Twist Cables: 30-70%
Chain: 85-95%
Cable: 0-98%
Rack & Gear 50-80%
Wouldn't the power lost be 5-10% in the case of spur gears, etc.?

That is, they're 90% percent efficient, with a potential power loss of 10%?

That was confusing to me and maybe others. Otherwise, it's great.
