Small Scale Grain Threshing Machine

In an effort to grow a higher percentage of our own food, we have started devoting a significant amount of our growing space to grain production. The growing of grain is easy and requires a very low amount of labour input, but the harvesting process is much more labour intensive if everything is done by hand. I built this small scale threshing machine to help accelerate the extraction of the grain. The upper drum contains rotating beater bars that knock the grain out of the husks and the lower winnowing chamber separates the grain from the chaff. It works quite well so I hope sharing this project helps inspire you to grow your own grain at home and maybe even build something similar to help with your harvesting.
