[Konstantin Bogach]

Larry,  thank you for detailed explanation.   I will do either this or 
cut out in a cheap deep socket depending what I see first.  I just 
thought that a socket 15mm with cut out for a wire is what everyone is 
using.   But I never saw such sockets except OXS size.
Thanks again.
Konstantin.
