Warped plywood

	I am in the process of remodleing my kitchen and need to make some new cabinets. I bought the plywood, had it cut to width at the store and brought it home. Then vacation, kids camp and work got in the way for about six weeks. The plywood has been stored vertically in the garage and some of it has some pretty good warpage in the long direction. Does anyone have some ideas on how to straighten these out so I can still use the plywood? Should I attempt to straighten before cutting to length? Any ideas would be greatly appreciated.

Texer,

If it was straight when you first bought it, chances are it warped because it absorbed moisture unevenly while it was stored in the garage: the side facing outward dried more then the other side, causing it to curl. Try placing each sheet by itself on supports (sawhorses) overnight, and see if it doesn't straighten when the moisure content on both sides equalizes. If you're in more of a hurry, you could place it on the lawn in the morning, cupped side down, and let the combination of sun and wet lawn on either side take care of it. For cabinet grade plywood, thought, I would give the sawhorse treatment first try. Gary

Thanks Gary. It was pretty flat when I bought it at HD - but it was in a stack. Some of it is so curved that air now gets to both sides so it must be at equilibrium. I will try the sawhorse method - it is pretty nice maple-birch plywood so I will try the lawn as a last resort. Thanks again.
