Can a board be unwarped?

Only way I can think of is to use steam.

Board that warp quickly can be dangerous when sawing, they just seem to
have a mind of there own. I usually just get rid of them, or cut it up
for small projects.

Y'know, it just might have to do with moisture content. Moisture
will swell the wood on one side, and removal through heat on the other
will contract it. Another way is to lay it on the lawn on a hot
summer day. One side will draw moisture, and the other will heat up
and contract.

The short answer is: No. You can fart with it till the cows come home
and it will still be warped. Save the time and aggrivation amd get
another board.

I just read in an old textbook tonight a way to straighten it.
Put the concave side down.
Put a wet towel under it.
Put a heatlamp on the top (convex) side.

I have no idea how that is supposed to work, but that's what it says.

P.S. Any striaghtening will nto be perfect, so a good plan, if on
shorter pieces, is to tack to a bit of MDF with hot glue, and run
through the planer to get one side flat, then remove and turn over to
do the other side.
