The Power Hammer Cycle: How to Cure the Bang Tap Blues Everyone that has run Little Giant power hammers or the other derivations designed by the Meyer Bros such as the Murry and Moloch knows they can be very quirky. When out of adjustment, worn or run too fast they go into a spasmatic cycle popularly known as the "Little Giant Hula". The ram goes up when its supposed to go down and down when its supposed to go up! Every part moving to extremes but not doing any work. The "hula" is the worse case but almost every Little Giant suffers from the "Blues" at some point. There have been many explanations in the past but Dave Manzer is the first to have studied the problem seriously. Dave has taking a scientific approach to the problem using strobe lights and high speed photography. He is the first to correctly explain in detail the dynamics of the Little Giant and why things go wrong.
