I recently took apart and rebuilt an traditional, old pine door. I have been told it was left for too long in a stripping vat and this caused the wood to shrink and crack and the joints to come loose leaving the door sagging on its hinges and dragging on the ground as it attempted to swing.
It was a fairly fiddley process that took about 12 hours. All the tenons had to be reconstructed, for which I used various pieces of hardwood. I also filled some of the major cracks with slivers of wood, and for the minor ones I made up a paste from, Lakeland Paint’s natural wood filler and their wood glue, also some fine sawdust and coloured acrylic paint to blend it in with the rest of the door.
Anyway, once it had been cleaned up, glued (also from Lakeland Paint) and clamped and left to set, it came out as a sturdy door with character, and hung again beautifully.
