I think it's time to send this Vertex HV-6 table back. I put it on its side (in the vertical position) and it bound right up. It won't turn at all, even with the worm gear fully disengaged; i.e., I cant even turn it by hand. When I first put it up on its side, it turned a little bit, maybe a quarter of a turn or so, and then it just stopped.
Has anyone had this problem before?
