Svarven och svarvaren: En hantverksundersökning om att använda en trampdriven och en eldriven svarv

Abstract

The lathe is probably our oldest woodworking machine. Despite its long and rich history, the knowledge of using the foot powered lathe has disappeared with the industrial revolution and electrification of machines. The object of this thesis is to investigate differences in using a foot powered lathe and an electric one, in order to say something about the interplay between turner and the machine. The question being: what differences are there in using a foot powered and an electric lathe and how does it affect me as the turner and the products that are produced? Based on my knowledge in woodturning and with some help from a woodworker only using foot powered machines in his work, a comparison study on the university’s two lathes was implemented. The results show that working at the foot powered lathe is more demanding in that it requires more focus, balance and stamina. The placement of the tread makes it difficult to get as close to the lathe as with the electric lathe, which affect the working position of the feet and the arms holding the tools. The differences in rotation speed and that the construction of the foot powered lathe are lighter and wobblier than the electric one, also affect the work. All differences above in turn also affect the outcome of the turned products.
