Nose weight

[Gene Maurice]

Steve,

One negative to consider is that adding weight to the spinner turns it into
a flywheel thus increasing the possibility gyroscopic precession, ie.
"Gyroscopic precession is a phenomenon occurring in rotating bodies in which
an applied force is manifested 90 degrees later in the direction of rotation
from where the force was applied."

Subject: Nose weight

I have to add about 2 1/2 oz of weight to the nose of my pattern plane for 
static balance. Has anyone ever tried pouring molten lead into an aluminum 
spinner to get the weight as far forward as possible? I would probably have 
to epoxy the weight in place and balance the spinner/weight, and wonder if 
this would cause undue stress on the engine bearings. Any ideas would be 
appreciated.
