Any advice much appreciated. > > Sid Blum Hi Sid, This is what I do. Cutting a long diagonal kerf most of the way through the key, usually from the bottom, glue and either clamp or shim to rotate the key in the direction you want. Where and in what direction you saw the kerf(s) depends on where and how severe the warps are, how much key width you have to work with, and whether you intend to shim or clamp. It's pretty straightforward, but takes some conceptual orientation before you start sawing. Titebond, naturally, to glue.
