Very similar to this previous “tumba horror” case, I received another one. The tumba has been broken into several bigger parts and then glued together with an unknown compound. I have no idea what happened to this beautiful instrument but it is clear that the defect has not really been properly repaired

People then think that ordinary wood glue is not strong enough and use modern synthetic glues to get things solid again. Unfortunately, this is not really the way to go. It is important that the various pieces are put together properly and as quickly as possible with ordinary white wood glue.
So, in this case it was back on. The whole thing has to be taken apart again, the synthetic stuff removed and the pieces made to fit again.
Since several large surfaces are involved, the job has to be done in several stages.
The tabli was also well loose and was the first part to be separated. Then the larger parts were taken apart. In the end, not really much remained…

A spectacular image, though…

Piece by piece, the tumba regained its original shape. Because the parts no longer fit 100% well, reinforcement was applied along the inside in the form of strips of cotton cloth soaked in white wood glue. Holes were filled with a mixture of wood glue and sawdust.
Then the tabli came back on.

The transitions between the different tumba parts are made smooth with some sanding and plastering with wood glue.

Finally, the whole tumba gets a new coat of colour and lacquer. Ready for a new life…
