I restore a very cool and useful geared drill press that weights around 250kg (550lbs) made by “Officine Meccaniche Mazzoni” in Milan around 1950 (No date found on the drill press so hard to tell precisely when was actually made). The gearbox allows shift between three speed that combined with two speed of the three phase 1.5hp motor enable six speeds to the quill. It’s very easy to run any of the six speed as there are no belts to move, just a cople of knobs to turn. I love this so much!
