[CAUT] Yamaha grand screws too short?

[Ed Sutton]

Wait!
Before installing larger screws, examine the core material of the lid to 
find out why it let go.
If the lid core is splitting or crumbling, it may be more appropriate to 
consolidate the lid material with thin epoxy and replace the original 
screws. Putting larger screws into crumbling particle board will just make a 
bigger hole.
