Scully Lathe Restoration and Modification

The AM44 Disk Mastering Lathe Project

The AM44 is a Neumann-based lathe, built on original Neumann castings, manufactured around 1944, during the second world war.

The project was founded by Flo Kaufmann, in Switzerland, when he managed to find a pile of these rare beds in the unexplored depth of a warehouse. The plan is to build them up into fully functional disk mastering systems, using newly designed and manufactured parts.
