Here, the first post in this thread is what I did with Karen's door. It seems to have worked well; at least I haven't heard otherwise!
The usual problem with Burro
, etc, doors is that water gets into the inside of the door and the wood core rots, allowing the lower, curved, part of the door to sag, creating a big gap (and mismatch with the body) at the lower part. There have been plenty of fixes posted here, from kerf cuts and re-glassing, to threaded tension rods, to dismantling the door completely and fabricating a metal core.
