I have a spruce top that was shipped and caught some weather on the way. Shipper replaced the set, leaving me with this extra top. It looks a little like a long potato chip. Is there a reasonable way to flatten these?

Sometimes placing it between two pieces of plywood or something similar and some weight on top can work. But I have come across some woods that no matter what will keep curling up...Mike

You might try ironing them and then clamping it... Otherwise it might straighten up once you brace it.

They're resting under some shelving; ironing sounds like a possibility.

I've used an iron, cooked tops in the oven, and bent them on a hot pipe and with a heating blanket. Eventually you should be able to get the wood to flatten to the point thinning and bracing will eliminate any remaining warp. After any heat treatment, sticker flat and under pressure for quite a while before you mess with the wood again.

Spritz the concave surfaces with water (Distilled), then sticker. Run an oscillating fan(on low) over the wood and flip and spritz as neccessary. When it reaches equilibrium, it will be flat.....or firewood.

I bought a reject (pretty thin) cherry back once that had a bad
curl/twist. It's been sitting between two flat plates with
weights for about 5 years. It was flat after about three years,
but I'll keep it where it is until I use it.
