Topic tags/keywords: warp flattening boards milling planer jointer

Hi All!!!

I did a quick search and couldn’t come up with the answer, though I thought I had seen something here before.

I have cut up some red oak for a knock down bookcase. The rails and styles are 2” wide and various lengths. The wood sat in my cellar for a week or two before i cut it down to rough length and finish width. As soon as I cut to finished width and stacked everything up, I noticed a lengthwise warp of maybe 1/8”. I’m pretty sure I don’t want to ignore this, but maybe I do.

Assuming I shouldn’t ignore it, what is the correct way to remove the warp? The boards have not been planed to finished thickness yet, so I have some room to play. Now that I think about it, maybe I need to run it through my jointer to take the warp out…

Any thought are appreciated.

How long are they?

Are they twisted or just bowed?

I see that you live in MA. If your wood was stored basically in outside air conditions, it may have picked up moisture when brought inside your basement. In the Winter, the outside air, especially in below freezing temperatures, is extremely dry. You probably need considerably more than a week or two for your wood to become climatized when you bring it inside.

Let it sit for a few weeks longer, as it may still be soaking up moisture, and may yet move some more.

GaryK – They run about 40” in length.

Biowa – My cellar is unheated…at the moment, temp is probably between 45 and 55 depending on the actual outside temp…and probably almost as dry as outside, given the rest of the house is very dry. That being said, I will let it sit for a while longer…

Thanks!

I would also let them sit for a while before doing anything. Make sure that air can circulate between the
boards.

If that doesn’t do it, then you could joint and then plane then to size.

Thanks Gary,
