So I got mine last week and the arm was floppy as hell. I've tried several methods of fixing it, without the desired results. I first trailed nail polish, but that just flaked off when I rotated the arm. So then I tried putting some tissue paper in the gap between the pin and the joint (as that's the problem), which worked for a while but then it tore up and started dropping down again. So I managed to fish that out, bit the bullet and spent way more than I'd have liked on a bottle of Pledge Revive It (I figure it'll last me forever though) and even that hasn't thickened the joint enough. I guess the last resort is super glue, but I'm concerned about it fusing the joint entirely... Ah well, I got him cheap so I'm not as annoyed as I would have been if I'd paid full retail, but it is irksome not to be able to position his arm properly. That video in the thread made the fix look easy, but I guess mine is just a pretty severe gap. The pin and 'ratchet' move around visibly when the arm post is moved.
