Making a platform (likely just a board) attach to the head of a tripod; help?
I got a new tripod for my camera recently and would like to convert my old one into something resembling a nightstand or tv tray; I was thinking of using a board or flat surface with a nut or something similar attached to the bottom that would be the right thread size to screw onto the tripod. The idea would be to have a platform/tabletop surface that could have its height easily adjusted up and down; I know they make things like these, but I'd rather not pay $85.00 for a 15 inch piece of plastic that's ready-made to screw on to tripods (like this: http://amzn.to/9k4i2N) or $150.00+ for an adjustable end table (like this: http://amzn.to/a6UExN) when I can probably make something very similar myself for a fraction of the cost with the right equipment. problem is, I'm not very handy with this type of stuff and don't really know how to go about attaching a threaded hole to a board or what type of threaded hole I should even be looking for. I figure it can't be that hard, though. Any help?
