>Keith: >By that ratiocinated logic, then everything was made to be removed; why, >those 5/8" lag bolts look easy as pie to take out! >Paul Revenko-Jones Paul, List, Your logic does have some merit to a point. However, and specifically, I would disagree to the example you have used. Removing a lag bolt would not be as easy as pie in comparision to removing the slot head machined bolt holding the bar in question. >In all seriousness, analysis of the tension structure of the plate would lead >me to believe that removal under full tension is a poor idea. With all due respect and not trifling or jesting, Paul, I certainly have no issue with you, or anyone else, from extrapolating such a belief. Such a thing just never entered my mind, and still doesn't. >I would check >with Bob Beck in NJ; he's the resident know-it-all on plate manufacture and >design. Having attended Bob's classes and briefly meeting him in the past, I would concur with you on his vast understanding on plate manufacture. However, consulting with him in this particular matter would serve no purpose for me. I simply cannot yield to the notion that removing *that* particular bar for damper work, or for the performance of certain pieces, in any way jeopardizes the structural integrity of the plate, especially after personally having experienced such an activity firsthand on two different pianos.
