Easy Way to Straighten Lumber & Keep it straight UPDATE

Someone told me it is easy to straighten crooked, warped, cupped lumber. He said all you have to do is put it out in the rain. As it soaks up the water, it will straighten right out. In the first video, I took these extremely warped ponderosa pine boards and left them out in the rain to see what happens.  You can see that video here.

In the next video, we find out just how well that works. You can see that video here.

In this video, we find out, as expected, after they dry out again, they are just going to warp back to where they were. In this video, we will do an experiment to see if we can get them to dry straight.

    In Europe they used to leave the logs in a pond before cutting them for a time, that way the sugars and starches in the wood get dissolved. That reduces the warping by quite a lot.

    I screwed some wet pine to the joists in the basement for about a year took them down and made the frame for a screen door. works like a charm

    Thank You for your honesty in such a practical application. All homesteaders can benefit from such knowledge!

    I have a Woodmizer LT-40 and saw quite a bit of southern yellow pine as well as hardwoods. If you would build yourself a pallet the length of the boards you are cutting with supports for the wood every 1 to 2 feet depending on the wood species, stack and sticker your lumber and then band your pallets with ratchet straps they will air dry and remain straight. Just remember to keep your ratchet straps tight and check them weekly. As the lumber dries and shrinks it is imperative to keep the straps tight. Keep your pallets out of the sun when drying and cover the tops to prevent water from rain soaking the boards again. You will get better results.

    That mold is also called "Blue Johning" or Blue John. Many inspectors will make you remove blue johned lumber in interiors. Something you can look out for is that one board you held up and said "just look at this" .. I saw that a knot or limb went all the way across the board in both places where it was bucked and warped(that'll do it every time) A really time consuming method but effective in limiting warping is quarter sawing. But like I said, it's labor intensive and wastes a lot of lumber. It does make beautiful grain or tiger stripe lumber., common in guitar making and very desirable in certain applications. I do like your approach, simple and to the point.

    So glad I found your channel. I live near a locust only lumber yard, the off cuts are super handy around here.

    It's common to make assumptions and predictions. The only way to know is to experiment. But also, what may work for those few pine boards may not be the same for large lots, or other species. Attempt, and learn. Intelligent approach to find a solution to a problem.

    Your honest approach to YouTubing is refreshing. I work with wood as an amateur furniture maker in rainy England and crooked planks are always a problem here, even store bought planed timber is usually warped from poor warehouse storage, drives me nuts that they can get away with selling it like that. Will be interesting to know how your experiments turn out.
  • @JacVisser
    There is very little you can do because warping is dependent upon the density of certain areas inside soft wood, like knots and the heart of a log. The softer areas acts like a sponge and expand when wet, conforming to the original shape, while the denser parts take longer to absorb water and stays solid longer with more resin content. Then when drying, the softer wood expands away from the denser wood, opening up so to speak

    The first YouTube channel NOT devoted to instant gratification. ;) fortunately for me, this update was from three months ago, and there may be an instant result… lol (laughing at myself)
  • @Shifffyy
    Awesome video! Looking forward to the results

    In my experience, if weighted while air drying, once dry, they will stay flat unless they are not secured or primed and painted when the relative humidity rises. Therefore, boards installed inside normally only require a few finish nails, while exterior use may require screws. I have seen a sidewall where many of the 8d galv. nails had backed out and fallen on the ground within ten years!
  • @1Shaco
    I love the update man , looking forward to the end results
  • @expensivefreedom
    I just found your channel and am really enjoying the content. Not sure when summer ends in your world, but I’ve subscribed and turned on notifications so I look forward to finding out how this turns out. Keep up the great work!

    I have screwed some boards together with some deck screws and it helps.
