I’m trying to make a sliding bathroom door with a pine side and a reclaimed wood side glued/nailed to an OSB core.

I have the pine boards glued and screwed to my OSB core, but upon polyurethane coating, the door began to cup and warp at the ends. I was planning to glue and nail the other side with reclaimed wood, but now im worried about the door warping more… Is there a better way to make this door?

How would you guys makes this door?

I have made several sliding doors for the house similar to what you are trying. The wood is wet and the substrate is too thin.

Thin OSB (or even plywood) is not a good substrate for a door like this. You are going either need to use a much thicker and better quality plywood (2 3/4 Baltic birch ply sheets come to mind) or a structure similar to a torsion box. Have you considered getting a regular, plan hollow core door and then gluing your boards to it? If you search the web, you can find a ton of videos on how to modify or build your own hollow core door.

Wow, 2×3/4 birch ply? that seems very heavy! I almost went with a 3/4 birch ply, but felt it was over kill. I do like the idea of a torsion box, never heard of it before. But it looks lighter and very stable.

Have your say...
