Hello,
This is a question in regards to dealing with a twisted board that is already rough milled.
I purchased some rough tiger maple several years ago. 6′-8′ long, 6″ or so wide and 4/4 thick. The boards have been stickered in my garage, attached to the basement (under my main living area) for all this time with 3/4 plywood sticks. I recently decided to use a a board for a small project and ran into some problems.
The board coming out of my stack was twisted. I am fairly familiar with how to deal with lumber having ‘some’ cup or warp. But this board is not making me happy. I recall recently reading an article in FW on how to deal with these types of issues and figured I dig it up to see if it may help but before I spend a lot of time, maybe ask if I even should atempt it.
I needed a board roughtly 4″ wide and 36″ long 3/4 thick but 5/8 is OK. I brought it into the basement from the garage, same level, but of course not same temp. I did the usual, jointing, then planing using each side so I would take off fairly equal amounts from each side. I got it close to final, 5 1/2″ wide, and 40 long and 7/8 thick. At this time it was perfectly flat.
Then I left it on top of my planer (on the two roller supports). Things came up and I had to stop for a while. Now I’m at it a few weeks later. Looking at the board now, it’s twisted again! I should mention, that in RI, it’s been winter for qauite a long time no humidity to speak of.
Sooo, what to do? Since I only need it to be 4″ wide, I figured perhaps I can cut it in 1/2, shorten it a few “, take another 1/4” off the thickness of each 1/2 and glue it back together. However, is there a way I can guestimate if this will work or if I’m just wasting my time?
Any thoughts, suggestions, comments on the artcile (I still need to find the issue).
Thank you, Gabor

Twisted Board
I think you're probably wasting time. A quick search of the index - try FWW # 177 - Doug Peterman article
I'd get another board -

Some thoughts
I've had this happen with freshly milled boards, even overnight, when I lay them flat on a benchtop after milling. Moisture content is never evenly distributed throughout a board and tends to be a little wetter in the middle. When you mill a board you take material from both sides, bringing the slightly moister center closer to the air. The board then begins to find equilibrium again. If one side of the board is flat against the workbench the other side will lose/gain moisture (depending on the humidity) and exert stresses throughout. There is a possibility that if you sticker the board for a few days (or maybe several days) it might straighten out somewhat. It's kindof hit or miss here, but I've had it work before. Or you can re-mill it.

I call this fireplace wood. Frustrating, yes?
