Share 'Baking Tops'

Greetings Frank et.al. Most of the tops I build with are old spruce and have been stable but some of the newer cut Lutz I've used is not. There have been some issues. I think I need to get into baking these babies. Frank, Addam Stark suggested I contact you about your feelings on this. Any guidelines as to how long, temps, etc. etc.? Thanks a Million Terry Kennedy www.kennedyguitars.com
