How do you guys who use wide boards control warpage once the project if finished? Say to do a table top with 12" wide boads. How are you holding down the top to allow movement, and still control warpage?
I was taught to never use boards more a width more than 8X the thickness. I cheat a little, but not much. The only time I did wide boards were some 3/4" thick drawer fronts that were 6" wide. Some have cupped a little over time.
Apparently I'm too paranoid here. Can you shed some light on my ignorance
