Geared Windmill rocktumbler

This is my entry for the #CatchTheWind contest. This is a windmill that has a 11 to 1 gear reduction to enable you to do things that you just can't do without gearing. Things like pump water, power complicated whirligigs with many moving parts, or anything else you can imagine! This one will power a rock tumbler when it is finished. My wife doesn't want a rock tumbler in the house because of the noise so this will have a home in the corner of the yard closest to my most annoying neighbor. Pleas
