    I have repaired, modified, and rebuilt high capacity hydrualic
    presses. I did this for a living in a previous life. Hydraulic
    presses are dangerous. As the press capacity gets to 50 tons the
    dangers become very significant. I am talking about broken limbs.I
    have worked with machines which used hydraulic presses in a portion
    of their make up. These machines come under strict OSHA codes. If an
    employe is indjured on a machine that is not built compliant to OSHA
    codes, then the owner / manager could be taken to court. This is no
    joke. I have rebuilt 50 Ton hydrualic presses retaining only the
    pump, cylinder and name plate. 

    I would recomend that anything above 30 ton capacity hydrualic
    presses should have guards in place to prevent flying projectiles
    from striking anyone in case of failures. A guard should be both
    efficent and easy to work with. Eye protection and a face shield
    should be considered as vital for 20 ton machines. Electrical or Air
    powered machines need to have a well considered tag out / lock out
    proceedure. The 50 ton powered machine had broken a man's leg when a
    part being pressed flew over 10 feet, striking the victem who was
    just walking by. The near by 100 ton press, no one would use. 

    These machines harness unseed and little appreciated forces to do t=
    heir work. I would be hesitant in fabricating any press rated over
    50 tons for use in the jewelry trade. However i would fabricate one
    rated at 30 tons. It would be guarded and to code. I would also wear
    protective lenses or a OSHA face guard. I am accustom to having
    worked in an environment which could kill or cripple me. Please be
    professional. It is easier than being hurt Journeyman AFL CIO
