Hi Clyde,

About the light problem mentioned below.  I found a fibre optic extension
cap, that fits
over my Mag lite, (the size for AA cells).  I can feed that between the
action parts, and illuminates the area, I am interested in.
I got it from one of those tool trucks, that travel around between garages.

Regards,
John M. Ross
