Re : Lead Calcs
If you are going to abandon calculating and try weighing a test-jam-jar you are
at a risk. Use a larger test volume. The packing ratio of the shot that is in
contacht with the walls of its container is lower. In the middle the spaces
between te shot is filled more effciently with shot.
|OOOOOOO|
| OOOOOO | LARGER VOIDS
|OOOOOOO|
-------------------
|
|__>>> SMALLER VOIDS
Multplying the jam-jar volume to calculate the amount of shot in a keel
introduces a relatively large error. A small object (jam-jar) has more surface
its volume than a larger one (keel). Maybe weighing a series of different
volumes can give fou an idea of the actual influence of that error.
