The Powerhammer Cycle:
A "must have" for every Little Giant owner! - guru
Sample of Video (Introduction)
SEE Dave's NEW Power Hammer Video Power Hammer Tooling and Techniques
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 spasmotic 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 extreames 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.
This video explains his methods, conclusions and solutions to the problems. He shows how you can tune up your Little Giant so that it performs better than from the factory and at least as well as any other mechanical hammer.
Among other things he points out that as-built, Little Giants have design flaws that are easy to correct. He also points out examples of construction flaws that lead to erratic operation.
Dave also points out that many Little Giants are setup to run too fast. I've been telling folks this for years. Dave explains how to tell if its running too fast and what to do about it.

FROM the V. HAMMER-IN
Junk Yard Hammer (JYH) Builders: If you are designing your own hammer or using someone elses plans such as a Tire Hammer with the Dupont linkage (toggle arms and coil spring) this video is a MUST HAVE. Dave explains the dynamics of this mechanism accurately and like no-one else before or since. Dave goes through the adjustments and why you need them, shows proper and improper functioning of the hammer. This knowledge is even more important to builders than to operators.
