  • Best way to drive a letterpress

    Hi all,

    I just bought one of these:

    a Golding Pearl #11

    the foot treadle is missing, so I need to rig a motor to the flywheel shaft. I'm looking to drive it with an AC motor and VFD. (So that later on, I can put them on a small lathe).

    This is a decent way to do it, right? And also, does anyone in the Maryland area know a good local place to pick up a .5/.75 hp motor?

    Thanks,
    Phil

    Phil,
    At the Buckley, MI OldEngine Show Print Shop, we have a couple of letter presses similar to yours, powered by motors. We use a flat belt, running around the flywheel, driven by a crowned pulley on a motor-driven gearbox. A VFD as you describe is much-desired and works well. I think we have the presses running about 60 cycles/minute.

    You should be able to find a suitable motor at a scrapyard. Take an ohmmeter along.

      Wow

      I haven't seen one of those actually run since I was a teenager just starting out in printing, and they were rare even then, most of the ones I see are all fancied up with chrome and such, and are displayed in the lobby of a printing company.

      I would say a 1725 motor (and a VFD maybe) with a pretty small pulley to drive that big flywheel should drive it slow enough to make it usable.
