Sliding door repair
I have a Danish teak credenza. The doors have a clever design as they roll to side and disappear when opened. The doors are constructed of small strips of wood on a flexible back. A portion of thedoor has come off the track. There are dowels at the top and bottom at the end of the plastic track. The dowels are glued in. Do they need to be removed in order to realign the door?
Hmmm... From what I can tell from the one photo, the dowel is not a stop preventing the tambour from being removed. Something's gone out of square at some point. The tambour shouldn't have been loose enough to jump its track. Have you recently moved the credenza or is your floor not level? Anyway, some pieces require removal of the back panel to slide the tambours out. Check for screws. I know it's cumbersome, but can you try to post more photos? Maybe one of the entire front?
I've got a similar issue with a sideboard with tambour doors needing repair, and I can't figure out how to remove them. I'm really hoping you can help. I finally found that there screws coming up from below that hold a strip of wood in place that the back panel seats into. Unfortunately, both ends of the panel are set into strips of wood on each end, which are themselves behind a "lip" on the sides of the cabinet. The panel and bottom strip of wood can flex out away from the cabinet but the top of the panel is in a groove on the underside of the cabinet top, and the ends of that bottom strip are being held in place by something else. Here are some photos that I hope make what I'm saying understandable.
