Help building something that will go back and forth

  1. Jan 30, 2009 #1
    I was wondering if you all could help me. I need to build something that will move a rod of wood back and forth in a fashion similar to a musical metronome.

    I am hopeing to make it for under 50 dollars and need it to go about 200 rpms at min.

    all you need is a small electric motor, perhaps with a reduction gear, and a single linkage attached above the pivot point. Try a hobby shop.
