That *observable cumulative damage* needn't be there. Whether damage is done mainly depends on when the bolts are checked. If plate bolts are kept snug by checking during the summer, (high-humidity) months, they don't exhibit the continual creep that ultimately results in stripped threads. In my records of the school grands, I found that tightening the bolts in winter never stopped, I was stressing the threads yearly . Since I began putting the wrench on only in summer, I very rarely see anything turn after the first two seasons. All the older grands are settled in and exhibit no additional looseness. If the bolts won't turn in summer, they are (IMHO) tight enough. Regards, Ed Foote (And I wonder why all those people said I had a screw loose (:)}}}?)
