I going to build a pair of barn doors for our kitchen pantry (think closet with double sliding doors). I’ve worked with salvaged wood before (see projects), but am trying to decide which would be better from a weight and stability point of view. Right now I’m thinking of a typical door consisting of vertical members with a Z overlay.

Option 1: Build the door from salvaged 2×6 and 1×6 for the overlay. Pros seem to be ease. Cons seem to be weight. I think a typical door size in doug fir will be about 70 pounds.

Option 2: Use a plywood base (1/2”) and glue a barnwood facade (maybe another 1/2”) on top. Pros seem to be weight (the door will be thinner). Cons seem to be questions of wood movement such as cupping since the doug fir will be thinner. Also more complicated as I’ll need to do something on the edges to hide the plywood. The back shouldn’t be visible as it is to a pantry.

Thoughts? I always like other opinions before I start down a road.

Option 3: I’ve come back to say I suppose option 3 could be to build the door out of salvaged 1×6 with 1×6 for the overlay. My question is whether this will be stable enough from a cupping/warping point of view.

I would use the plywood option to keep the boards straight. You could glue and screw from the backside. I don’t think wood movement will be a problem since you’re not gluing up a panel. Have your 1×6 over hang plywood by an inch or so on each side and rip 1x to hide the edge. Bottom and top will not be seen.

I agree with Bill. Use plywood,3/4” for the doors. cut kerf lines vertically to look like it is made of lumber. Make your Z bracing out of 1/4” hard board painted black. Or you can paint the hardboard to make it look rusted like old metal pieces. Lightweight and completely stable.

Here’s a question because I don’t use fasteners for almost all of my projects. What do the screws do that the glue doesn’t do already? Educate me.
