As a teen, I worked in an audio store and assembled many audio/video cabinets. It amazed me how a 4' high cabinet, that swayed 3-4" side to side, became rigid once a flimsy 1/8" thick pressed-board back was attached. Likewise with framing walls. Many stud walls have cross bar spacers, even diagonals incorporated in the framing. However, it is not until the sheathing (3/8" press-board) goes on, that the wall gains it's lateral stability. If this picture works for you Keith, I would recommend gusseting a full sheet of material to the piano's back, rather than using the reinforcing blocks. Cut openings (sound holes?)in your plywood (between the backposts), glue, and use screws around the full perimeter, and up and down the back posts. This will give all the lateral strength that is possible, and will help more with the torsional thing (twisting, racking,.. "geez Roger always comes up with the best words!") than the blocking possibly can. Also consider adding a vapor barrier with a fabric cover to the piano's back. This will be of tremendous benefit to the Dampp-Chaser system. We use clear poly (by the roll) and cover with black "rip-stop" nylon. If you find merit in the idea Keith, your welcome to e-mail me direct, or call 1-204-727-7462 with any questions. best regards, Mark Cramer, Brandon University -----Original Message----- From: owner-caut@ptg.org [mailto:owner-caut@ptg.org]On Behalf Of Michael Jorgensen Sent: Tuesday, April 10, 2001 6:02 AM To: caut@ptg.org Subject: Re: need ideas I'm still laughing, --But really, The chains will just rip the studs out, and the screws will only pull the floor tiles out. To level the floor, simply flood it with epoxy. OOPs! Leave the piano in there and it shall forever stay put. Or, casters could be mounted to shock absorbers or springs. -MJ Newton Hunt wrote: > Have them move it back to where it was.
