I used a very, very thin sheet styrene for the body of the piano and wrapped it around the base. I glued it with Goo, a rubber cement because it's gap filling.
Tiny bits used for the hinges.
I glued the model with Testors model glue and Goo. The wax paper protects the working surface.
I put a bit of glue on the hinges first to soften them before applying them.
Flip the piano upside down for pedals and legs. I made several different legs from tubing, square tubes and even sprue.
