Egg Beater October 25, 2011 Two crown gears back to back can mesh with 8 tooth gears at right angles.
Use that idea to make egg beaters.
Have a 40 tooth gear drive an 8 tooth gear on the axle with the crown
gears to make a FAST egg beater.
It can froth up soap.
Try motorizing the egg beater.
Many ways work.
