Warped fiberboard... how to fix?

[Chris Turner]

So, I just received 3 pieces of 6"X6" grey fiberboard in the mail. I live in a very hot (and currently really humid) state, Arizona.

2 of the 3 pieces I got are noticeably warped. What's the best way to remedy this? Is there a way that any of you have had success with?

I dampen the fiber, then flex it to get it straight.
Then Put something heavy on it to keep it flat while it dries.

Do the same as for veneer ,steam with steam iron & clamp flat

I second the steam iron. It might behoove you to do it once more before you assemble the pickup and lacquer it...if you are planning to do that step. I have also used a heat gun after ironing and clamping to get all of the moisture out of the fiber.

I do the same as T does. I had some flatwork like that the other day with eyelets installed and I got them wet and made a stack with corrugated cardboard in-between each one (because of the eyelets) and clamped the stack in a hand vise over night and it worked pretty well.

After you get it flat and dry it's best to lacquer it up.
