Ingenious Technical Solutions at a Saw Mill Built by a Romanian Peasant Craftsman

Abstract

In the paper we study the construction and functioning of a saw mill, empirically built in 1930th by a craftsman peasant in Sibiu area. The saw mill has a gear mechanism which allows actuation with animal traction, a rod-crank mechanism that ensures the cutting motion and a mechanism for self - advance of the wood to be cut. Kinematic analysis it is made, proving the ingenuity of the craftsman who has achieved a functional saw mill, whose advance motion is well correlated with the cutting motion. Different kinematic schemes and numerous charts are given, emphasizing the creativity of the craftsman, who empirically found the correct sizes for the mechanism’s elements
