Topic tags/keywords: toy box crack pine question

I built this toybox using 3/4 pine and stained it about 5 months ago. I used the plan on the Kreg website and used all pine instead of MDF. My daughter moved out and took it with her. Tonight she emailed me this pic, informing me that it had cracked completely through this one side. I’m wondering if putty would do the trick on this or what. Any suggestions?

Solid wood needs to be able to move. Plywood and MDF don’t. When she moved there was likely a change in relative humidity so the trapped panel cracked. I assume there are more trapped panels and they will likely crack as well. If you didn’t fill the screw holes, you might be able to remove most of the screws thereby allowing the wood to move and not crack. Sorry I don’t have better options for you.

If you decide you want to fill the crack(s), a simple putty is Bondo for wood. Very quick curing, too. Another way is to use wood flour (like from your sander) mixed into epoxy. Quick curing epoxy works fine. With the epoxy and wood flour mix, it will take stain very well. If you use the epoxy, you’ll need to have the piece level, and put tape behind the crack, because epoxy will run like honey, even when thickened with sawdust.

I’m not saying this will cure any future wood movement problems. If the panels could float, rather than being locked into the grooves or rabbets with glue or fastenings, they would be less likely to crack.
