can't collimate lightbridge

argh

So I have the trusty laser pointer in the eyepiece. The red dot appears about 4cm from the dot in the center of the mirror,.

No matter what I do to the screws on the spider, I can't get it in. I can get it to move around to the left, right, down, but not up.

The obvious answer is that I need to adjust the screws on the base of the mirror right? The problem is that adjusting these screws, the red dot doesn't move in the slightest.

What am I missing?

thanks
