This may seem like a stupid forum question, but it's hard to describe with words so I've attached a visual.
Anyway, I bought a used gini rig from a friend, but it didn't come with the screw to mount the rig the bottom of a camera. It is so hard to describe WHICH screw I need I thought I'd just upload a pic so you can see the mount on the rig plate. It's one of these weird proprietary screws that goes up through the bottom of the rig plate, through, and then into the 1/4 20 threads on cam.
What is this called and where do I buy it? Does anyone sell them in Houston? It would also be nice to get more of those little tiny screws that go into the secondary/very small hole on the cam bottom to keep it from pivoting (like the ones on a tripod plate). Same question. . .what is that called and where do I find it? I emailed gini rig and they decided not to get back to me ever.
