The Hamfa lathe was manufactured by Hazemeyer Machine Fabriek in Hengelo, a Company that had started in business making sewing machines. The change to lathe production came in the late 1960s, the aim being to produce a well-made little lathe suitable use by model and experimental engineers.
Of an interesting design, the lathe was not dissimilar in layout to that employed on the EXE 2.5" lathe, a model that made it début in the 1920s. On the Hamfa, the arrangement used a centrally-positioned round bar as the bed and, behind it, a stabilising rectangular bar and, at the front, a leadscrew with a dog clutch at the headstock end. On the EXE the components were identical but with both the bracing and leadscrew both beneath the bed.
Drive to the leadscrew was by a 3-step extension to the overhung headstock pulley, the speeds so provided being supplemented by a 2-speed gear train - the effect of which was to further reduce the feed rate and increase the available torque. From its appearance, it would seem that the headstock contained a speed-reducing backgear assembly. Should you have an example the writer would be interested to hear from you
