Re: Tama Speed Cobra Beater Head problem
Take the rod out, tighten the screw and look inside the hole where the rod was. Can you see the screw? You should be able to screw it all the way in without the rod there. This may be a cross threading problem. That is, the screw feels tight as hell, but actually isn't in as far as you think. I had a similar issue. Try a different screw, too. My bet is the screw isn't going in, although it may feel like it.
