Greg, thank you for your response. I don't even want to send the entire mount back, I think if they just sent me a new worm-block for RA it should fix this issue. The problem is now only confined to the RA axis and is really as simple as this:
1) Mount stalls with 2.5 turns worth of pressure.
2) Ease of the pressure at 3.5 turns and there is 1-2mm worth of play in the axis.
I've just emailed Mr. Steve Bisque and have explained the situation. I'm leaving on Monday for a business trip for 10 days so won't be able to tweak the mount anyway, if they ask me. What I'm hoping for is that they send out a replacement worm-block, and that it arrives around the time I'm back from my trip. I am hoping that all I have to do is install the new worm-block and just get on with my imaging.
I do believe someone here had an out-of-spec worm and he was sent just the worm-block and wasn't asked to send the entire mount back. I'm hoping that's how they treat my case because 1-2mm worth of play is clearly out-of-spec for this class of a mount.
