I have two tripods, one the Manfroto 190 Carbon Fiber and the other an older aluminum model. I would like to add a pole for elevation and I see you can safely do this by adding an adapter to your existing tripod. To do this your tripod's center column requires a 3/8" thread on the bottom of the center column... neither of which my tripod have. Can threaded plates be added to the bottom of a tripod for this purpose? Thanks for any suggestions.

I tried using the boards search field and only got errors, appears to not be working.
