Excellent. I was thinking about doing this myself, but decided to try and google it first. Bingo! I want to strap my gopro to my hang glider's crossbar (spar) and the regular gopro roll bar mount is to narrow (the crossbar is to wide) in diameter. So i figured a hose clamp should do the trick. Thanks for sharing this. I am getting two.
One suggestion - in the product shots, if you could just CGI in the real gopro (or just an outline sketch) and a hose clamp, so the users can see how the mount is used and what is the difference between parallel and perpendicular mounts.
