This Martin 12-string suffered a broken headstock. Here, I have glued it back together, and am preparing to reinforce the repair.
![12-string headstocks sustain high string tension, so this repair will have to be reinforced with splints.](http://d10j3mvrs1suex.cloudfront.net/s:bzglfiles/u/435709/826d0efc3fed23ccbaae4b94ec31a7192c019d4b/original/martin1203.jpg/!!/b%3AW1sic2l6ZSIsIjM1MHciXV0%3D/meta%3AeyJzcmNCdWNrZXQiOiJiemdsZmlsZXMifQ%3D%3D.jpg)
12-string headstocks sustain high string tension, so this repair will have to be reinforced with splints.
![The splints are cut from straight-grain, hard rock maple, and are being glued into routed slots in the headstock.](http://d10j3mvrs1suex.cloudfront.net/s:bzglfiles/u/435709/947d88726eec92065ac6e417bd8d07f79b957d81/original/martin1204.jpg/!!/b%3AW1sic2l6ZSIsIjM1MHciXV0%3D/meta%3AeyJzcmNCdWNrZXQiOiJiemdsZmlsZXMifQ%3D%3D.jpg)
The splints are cut from straight-grain, hard rock maple, and are being glued into routed slots in the headstock.
![The finish is being sanded off of the back of the headstock. I will follow up with fresh lacquer and color matching.](http://d10j3mvrs1suex.cloudfront.net/s:bzglfiles/u/435709/492cef47ed1d73f737059132fe320f1846db267d/original/martin1202.jpg/!!/b%3AW1sic2l6ZSIsIjM1MHciXV0%3D/meta%3AeyJzcmNCdWNrZXQiOiJiemdsZmlsZXMifQ%3D%3D.jpg)
The finish is being sanded off of the back of the headstock. I will follow up with fresh lacquer and color matching.
![I have color-matched and sprayed the back of the headstock with fresh nitro lacquer, seamlessly blending the repair into the original finish.](http://d10j3mvrs1suex.cloudfront.net/s:bzglfiles/u/435709/865b6c51b603b79bab3662eeb0fda8e1f97746cf/original/martin1207.jpg/!!/b%3AW1sic2l6ZSIsIjM1MHciXV0%3D/meta%3AeyJzcmNCdWNrZXQiOiJiemdsZmlsZXMifQ%3D%3D.jpg)
