What adapter do we need? (Magic Arm to Cineslider)
 

I'm trying to connect a Manfrotto Magic Arm to a Kessler Cineslider.

If any of you could direct me in the right direction, I would really appreciate it. If possible, I'd like to to be a quick release, but if that option doesn't exist, I'd be happy as long as it just works.

See attached pictures of what I'm talking about. Sorry they are not focused good. It's basically a male c-stand end into a standard 3/8" plate mount. I'm wondering if something like this would work? http://www.bhphotovideo.com/c/product/273347-REG/Foba_31_0182_Adapter_for_Accessory_Trays.html

Isn't the bottom of the stud on the majic arm threaded?

Hmmm... not this one. But now that you mention it, I do remember seeing another one around that maybe was threaded at the bottom. Not this one.

EDIT: Just confirmed, one Magic Arm DOES have the treading, the other doesn't. I bet it's the one I bought off of Ebay that doesn't. Hmm... The threaded one makes life very easy. The unthreaded... well, is there another solution?

Maybe the stud is threaded into the ball. If so just unscrew it and mount the ball directly. If all else fails there is always Super Glue. Ha Ha...
