Description: 
Links below to the complete plans for bike powered tools for small scale grain processing; a thresher, a fan mill/winnower, and a dehuller/flour mill. The plans guide a farmer or a fabricator through step-by-step instructions using wood, metal, and scavenged bicycle parts. The cost of materials is $200 per machine and the machines process about 1# per minute for each process. In a well equipped garage/shop the machines can be built in 20-40 hours each.
