Hello Bert, and everybody. I recently posted a message to the Musical Instrument Makers Forum (MIMF.COM) pertaining to acrylic zappery; as some makers of electric solid-body guitars have used thick acrylic bodies in the past.

A reply to the forum indicated that a piece of acrylic containing the pattern of discharge will be quite weak, and will likely crack along one of the paths.

Granted, many guitar players do not treat their gear like museum pieces. But I am curious - what has been the experience of many of you who have created Litchenberg figures? Has the material weakened to the point where actual discrete cracks have formed and is fragile? Thanks very much.
