Now I would like to tell you something about the machine.
The machine was manufactured in 1963 for the German Army. It was supposedly made available for weapons maintenance in case of deployment.
This machine was also available for purchase by private individuals. The price was exorbitantly high for the time, which is why there were hardly any such models in the private sector and they are hard to find on the second-hand market.
The development of the machine began in the early 1950s. At that time, Bosch had developed a universal device for the DIY sector, which was powered by a hand motor that was also a drill. Through extensions and further developments, this lathe was then developed as the highest stage of expansion. Production was discontinued at the beginning of the 1980s.
Tony Griffiths has also published an article about this machine on his website.
