First saw this at a Dutch Oven Bake Off in Utah and thought what a great idea. I know that you can send your Kitchen Aid Mixer off to have converted. Recently I purchased a vintage working Kitchen Aid Mixer and will be sending it off for the conversion. Here is the information:

This Amish machine shop converts the Kitchen Aid 5-Quart mixer to a hand crank mixer for off-grid use.

It functions just like the electric mixer. The creative adjustable crank handle allows you to adjust the speed so you do not have to speed up cranking for whipping. Simply loosen the black set screw on the end of the crank and adjust the handle speed for whipping creams, and sauce

Kitchen Aid Mixer has been converted into a Hand-Cranked Mixer!
