Pianotech

              To all, 

                      Sorry if this topic may has been discussed many times in the past and I just missed it,  but within the past year, I have had three different incidences in which a leg on a concert grand has folded under the piano or nearly fallen off when being moved. All three instruments where not on spider dollies but have the extra large double wheel brass casters. In two of the incidents, the scews of the leg plate that is in the uderside of the piano loosed up enough to create some play in the leg. This is what contributed to it buckling when going over a theashold or in one case a dampchasser extension chord. The loose screws of course can only be accessed if you remove the leg. In thirty five years of piano work this is my first experience with this. This might be explained by the fact the most of these years I was servicing concert grands on spider dollies. Now I have learned my lesson and plan to check the legs on these pianos each summer. Is this something everyone else has been experiencing with these piano with the extra large brass casters? Also, has it caused the institution to insist on putting the piano on a spider dolly, or have you just inacted a regulare maintenace schedule for checking the legs? Also, any tips on repair proceedures or tips welcome. 

        Sincerely,
