We have a pair of 8'x4'x4' built-in cabinets flanking our fireplace. It's an old house and when it was restored about 30 years ago, they made 8'x2' doors out of tongue and groove siding to give is a rustic look. As you might guess, the doors have warped and will not close properly.
I'm going to rebuild them inside and out. One will become a wine bar and the other just storage. The new design will feature 2' 6" doors on the bottom, 4' door in the middle and 1' doors on top. Face frames will consume the missing 6". Planned construction is 1x3 rails and stiles with a 1/4' plywood or MDF insert. The 4' door will have a center stile for extra support and I plan to use three hinges.
My question is will this be sufficient to prevent the large doors from warping over time? If not, are there any good solutions/techniques.
