I have a nice Erard grand piano that has some of the veneer which has
buckled due to humidity perhaps.
behind the veneer, the wood was scraped with a tool that left a
hatch-pattern, no doubt to improve the sticking of the glue used.
I was wondering if there is a quick way of flattening out the veneer on
the solid mahogany backing, perhaps with steam and/or an clothes iron,
or something that will permit me to keep the veneer on the piano
without unglue-ing the whole piece off.
