BalanceMasters

[bgiller@xxxxxxxxx (Bruce Giller)]

	There has been some talk on the Guzzi list about a gadget that will
balance big twin motorcycle clutches (as well as flywheels).  The company
is Balance Masters (http://balancemasters.com).  And one of their
applications is for driveshafts; mostly for heavy duty trucks,.  Mercury is
the 'magic' ingredient that does the balancing.  The driveshaft unit is in
two sections and is simply band clamped to the driveshaft about 1" from
either end.  About $90/unit; they come in different diameters.

Here is the blurb from the website:

BALANCE MASTERS, the same dependable Active Balancing System for truck
wheel/tire assembly since 1979, is now available for Driveshafts. This Active
Balancing System has been engineered to fit most heavy-duty trucks, buses, vans
and motorhomes.

BALANCE MASTERS are mounted at one end of the driveshaft approximately 1
to 6 inches from either end. This patented liquid metal (mercury) technology,
works by centrifugal force to help increase bearing life and reduce the running
vibrations up to 50% or more, they are made to last and are maintenance free.

BALANCE MASTERS works at all speeds while you drive and helps to eliminate
costly and inconvenient down time. The patented liquid material (mercury)
is not
affected by weather or temperature extremes and have no parts to break, wear
out or dry up and have a 2 year limited factory warranty against material
defects.

BALANCE MASTERS Active Balancing Systems is the Ultimate in on-board
balancing devices!

	I've never tried them but maybe they might be of use to those with
incurable driveshaft vibrations.
