Nose weight

[John Ferrell]

Make a mold from aluminum foil to go inside the fuselage around the nose 
ring.
melt the required amount of lead in a can with a propane torch.
Pour lead into mold
Either glue or screw the weight in place.

Channel locks work better than straight pliers to handle can.
Lead may be trimmed with pocket knife.
Silicon (bathtub caulk) is easy to use and remove, but has a 24 hour cure 
time.

Has anyone put together the math to figure out how far from the cg how much 
weight is needed to move the cg how much?
Knowns:
    current cg
    current airplane weight
    weight to be added
Find distance from current CG...
Or from a reference point?
