I made a knock off of a fig rig - the circle thing you mount your camera in to help smooth out shots and do some other cool stuff.
I made this using an old chrome foot rest off of a bar stool and a piece of metal I had laying around. You could use something like this and expoxy to hold things together if you did not have a small welder. I have painted it flat black since the video and added foam grips from a hardware store used to insulate pipes. The foam grips have taken even more movement out of the shots I noticed.
I am learning to use it so things look smoother. The footage in this video is right after I made it and just started shooting stuff once I put the camera on it.
As allways feel free to comment on the setup good or bad! : )
