A simple cutting machine for model propeller was designed and made for the use in the tank belonging to the Imperial Fisheries Experimental Station. It resembles, in general, to the templating apparatus for propeller mould, the moving arm being provided with tracer and cutter. For the tracer, it is necessary to prepare special drawings to show the sections of blade at various radius. Cutting work is nearly the same as in the case of ship model cutting machine. It may be a help for speedy preparation of series models of the same diameter, differing slightly in the pitch, blade width and blade thickness.
