I bought a cheap ball-head table top tripod several years back. The body was a hollow aluminum tube, so I cut it to length and put a seat post pin inside the tube and filled the space with JB Weld. I had cross-drilled the pin and put a couple small pins through to give the JB something to grab.

Drops into the rear seat post and I can adjust the angle with the ball-head. I have a remote for my camera, so I can take a shot at will.

I need to come up with something to keep it pointing where I aim it. And I need to find it. I think it slid back into the bilge from a compartment.
