New member but a long time lurker.
I glued several strips of wood together (making a dice tray). And the board cupped.
I think, but not sure, the cause of this was after I planned both sides, I placed it down flat on my bench for about a week exposing 1 side to moisture or allowing moisture to leave. Not sure which happened.
I’ve done some research with moisture and wood for the past couple of weeks and have made efforts in making spacers for my lumber and ordered a moisture meter to assist me in my current project and future projects.
Looking for some tips of how to fix this and understanding better what is causing this to cup.
I’ve placed the board under pressure for a couple of weeks and reduced the cupping a few millimeters and put it through my planner and reduced the cup a little more. I don’t/can’t plane it any more.
I’m looking for some correct information regarding on how to further remedy this issue. The info I am finding is conflicting.
I see some people say dry out (in the sun) the cupped side (the concave side) and others say dry out the crowned side (convex side).
Which is it.
From my research via google, the crowned side (convex side), is the side that has a higher moisture content than the cupped side (the concave side).
Is this an accurate statement?
I see people mentioning adding water to the cupped side (concave) and other say add water to the crowned side (convex side).
Not sure which is accurate, but if it is the cupped side that has less moisture content, it would make sense to ass moisture to that side, correct?
I have used my heat gun to blast the crowned side (convex side) to try to remove some extra moisture. It had a little to no effect compared to the weight that I left on it for a while. Perhaps this does not work or I am heating that wrong side?
I’ve recently come across this little how-to
These instructions state to add moisture/steam to the crowned side (the convex side) to help uncup wood. How accurate is that, as stated above, I am under the impression that it is the crowned side that contains the higher moisture content that is causing the cupping.
I’ll find out a bit more when my moisture meter arrives in 7 to 10 days.
thank you for reading.
