    Get PDF
    A handy, simply-designed press was built using a geared motor and a jack. The maximum force is about 1 ton. The piston can be driven at a wide range of speeds, from 70 to 0.07 mm/min, which are selected by a rotary switch on the operation panel. Based on our own experiences, we report difficulties to be expected, mistakes to avoid, and important factors to be considered in designing and building a press, with a view to give helpful advice to beginners.<論説
