It almost is gratifying to know little has changed regarding the restraining/constraining/tailoring core technology over the past twenty years. The big difference now seems only to be the evolution from CIC to CMC while realizing they are nearly the same. Brings back memories concerning the 10 mil copper sheets sandwiched around about 40 mils of Invar. Also the 10" maximum panel size comes back to mind. Would like to know more about improved processing techniques and how tailoring core, close to MLB surfaces, compares with constraining core useage. Also, what became of Kevlar and/or Carbon fiber technology? What's really great is to see so many old and new time experts coming out of the woodwork. What could this be a sign of? Hope Jame's original question didn't get lost. Seems like not.
