[ATM] Mirror stuck on pitch lap

[Francis J. O'Reilly]

Jerry,

Thank you for your time and concern. The lap was poured with the aid of a 
mold. It is channelled. I am trying the gentle method at this point, having 
been chastised for attempting a more aggressive method in my frustration. I 
am soaking the whole mess in a "Tupperware" type container. I'll give it a 
couple of days and see how it progresses.

Regards,

Francis J. O'Reilly
