warped keybed

[Newton Hunt]

Hi Stéphane,

I think I would look at why this is happening, what part(s) are warped
and how the current situation effects the case parts (fallboard and
keyslip(, the action regulationablity and if all looks like it will work
then I would cut and glue on a shim under the front rail, then plane
until it is properly bedded.

I would check everything out before gluing it on, fall, slip, pinblock
key blocks, etc.  Don't do anything you cannot undo until you have
checked everything out.
