If I remember I' ll take a picture of one I made from steel. It' s 3 pieces of 12" steel bolted together at the ends. This allows 2 elbow joints to adjust it. Next I welded a bolt that is the correct size and thread of the top part of a tripod (what the camera mounts to) I take this part and screw it onto my bolt and then mount my camera. On the other end I welded another piece of steel at a 90 degree angle and then welded a large lag screw that attaches to the tree. After reading this I think I better get you a pic. It works great and cost only a few dollars, but you need access to a welder and you need the top part of a tripod.
