I wanted to mount my gopro to my boat and realized that the bolts that hold the windshield on the console of my boat are standard 1/4" 20 thread bolts that happens to be the same size as a standard camera mount tripod bolt. I had an extra gopro tripod adaptor so I decided to make a gopro mount that could replace one of the screws for the windshield which allows me to securely mount the gopro without drilling any holes or putting any sticky mounts on the boat. Really like how it turned out here are a few pictures.
Gopro mounted on console
Mount replacing windshield screw without gopro attached (hardly noticable and can be removed and replaced by the original windshield screw easily).
