Gibson Mandocello Repair Part 4: Kristin will be gluing three ‘finger braces’ to stabilize the top crack and prevent flexing. Here she is applying potassium permanganate solution (an oxidizing agent) to the braces to better match the patina of the old wood. An old violin repair trick!
This is what I do for my day job. We refurbish cockpits with new avionics and instrument panels. The aluminum panels are built by me, and all new wiring gets installed after removing the original wiring. The end product is very nice.
