I'm going to raise my kitchen counter using 45x45 timbers. The timbers were acquired a couple of months ago and have been indoors since then. Naturally, they have now warped quite a bit. It doesn't matter much for the parts that won't be visible, but the parts that will be visible and need to be painted, etc., I of course want to sit as nicely as possible and not warp later.
Is it worth continuing with these timbers, forcing them into place (maybe even with heat/steam) and then fixing them with clamps? Will they inevitably start warping again later, even after I have glued/screwed/nail them in the desired position?
Should I go and get new timbers and install them? These will probably also start to warp when they begin to dry, right? Or should I get a different type of wood?
I've set aside Sunday for this and the hardware stores are closing soon, so if anyone has any wise advice on this, I would be very grateful!
