Replacing upright jack springs

[Cy Shuster]

Yup, stretching worked for one or two, but not all.  I'd like to replace.  I 
think I've got good enough access to the jack on this action that I can 
clean out the old glue without pulling the action and removing the wippen. 
The repair guide shows using a special reamer (like a Forstner bit?) to 
remove the old glue -- which requires wippen removal.

You say weak, not broken?  Have you tried the quick and easy route of
trying to stretch the springs?
If they break then, they need replacing anyway, right?
my 1.2¢.
