I am working a design for a dual camera mount for shooting underwater 3D video. One of the problems I have with my underwater video is stability. So I got the idea to add some lead to the base of the mount to increase the mass, in the hopes of smoothing the shakes. So my plan is to build a sealed PVC frame, with a lead weight integrated down low. Getting it pretty close to neutral should be easy before I've built anything. I was thinking something like 4lbs would be a minimum... Before I ran the numbers. 2lbs sounds more doable with 2in pipe.
Anyone tried something like this? Anyone have an opinion on how well it will work?
