Hi Richard,
1X6 sounds kind of light weight, I know it's not a huge grand but it's still
got to weigh up near 400 pounds plus her weight and the bench I'm thinking
over 500 pounds ( I'm being kind here I don't know what size lady she is) is
on that 1X6 V thing. I'd check and see how well it was constructed, nails or
screws? Crossbracing or just straight boards? Plywood over it I'm guessing,
I'm hoping, please don't tell me they used chipboard, sorry oriented strand
board. 1/2" is too thin it should be 3/4" or double thickness of 1/2". If
all of that isn't the problem try replacing the caster cups with something
smaller and more appropriate for those tiny wheels or take 'em off! I see no
reason for them to be on there if the piano is in the place it's going to
stay!
Mike
