Michael Andersen sent this photo of his damaged mandolin. He pointed out it’s the second time, the first time was for similar damage on the other side.
The repair was not unlike the repair I made to Eamon Doorley’s guitar-bouzouki (News, 18 February 2016), though less complicated. It needed just one very small patch, as shown below below.
When I suggested he should try not to damage this mandolin further, he assured me that next time he went for beer, the mandolin would be in its case. Problem solved.
