Static balancing (putting the prop on a knife-edge and being sure both sides are equal weight) is done during overhaul. Other overhaul parameters are: ++ blade tracking ++ Blade thickness and cross section at several stations ++ blade twist at several stations ++ magnaflux to check for flaws ++ a real good paint job to protect against corrosion
As said by others, it's a real good thing to do. Props do
sometimes fly apart and who knows what some previous owner
hit with it?
Something else to consider: while the overhaul is being
done, the prop can be re-pitched! Want better climb or
cruise performance? This is the time. For reference, I had
my prop done a few months ago in Oakland, CA for $375.00.
Dynamic balancing is done on the plane, using accelerometers
to check for vibration. Neither the above prop nor an
earlier one on another plane needed any weights to run
smoothly after overhaul.
