Just finished putting together a lower profile mount for my Canon S1 IS in its scuba housing. My first one (not shown) was gargantuan in comparison, almost 7" tall without the camera. This one is about 4.75" (w/o the camera) once you push the suction cups down. Haven't tried it this new one out yet... hopefully this upcoming weekend. http://picasaweb.google.com/qajaq8/Came ... r_projects I have used the smaller camera mount and it managed to stay put during a play session at the Deschenes Rapids. http://tinyurl.com/5oh59c (Well, okay, I didn't really push it to see if it'd stay on during a capsize and roll. But can you blame a guy who just got a tooth extracted a week earlier for not wanting to capsize yet?) The suction cups were sourced from Canadian Tire. They're located in the roof racks in the auto section as they're for making your own roof rack. The ball mounts are from Henrys. The plastic is just regular HDPE sheets left over from a Yost SOF project. Didn't use stainless hardware as this is just a prototype. I don't think the ball mount isn't stainless either (the body looks like anodized aluminum). But there's a catch to assembling the small camera mount. The suction cup accepts a machine bolt with M6 1.0 thread. And of course, the ball head is your standard 1/4"-20 so you'll need to make your own dual threaded bolt. Alf.
