The piano bench is usually designed as a shallow chest where the seat/top opens and things like music books can be stored.
Our piano bench has this design with a piece of Masonite stapled to the underside of the bench.
Over the years we have overstuffed the bench and consequently the Masonite failed.
The staples remain but the Masonite tore away.
In an effort to repair this useful feature I found a piece of plywood (beadboard in this case) in our remnants which Charlie cut the same size as the old bottom using it as a template.
The piece had been painted white so I painted the outside with some paint I had on hand just to darken it a bit. I left the inside white so it would be brighter when we opened the top of the bench.
The piece had to fit within the frame of the bench and be secured to a narrow edge on which it rested.
Because it is fastened from the bottom I wanted to use screws (nails would probably be forced out over time) but could not find any in our stash. I did find some spiral nails with a modified screw head (useless) that I thought would hold.
These nails went easily through the plywood but were stopped at the hardwood of the bench so I drilled a tiny hole through the bench to get them started. (I found the perfect thin drill bit which I inadvertently broke.)
This new bottom seems much stronger than the original. We’ll only know for sure when we stuff the bench with music again.
Can you fathom why things fall apart when they’re used for the express purpose for which they were built?
