I've had my second-hand Sirius dome mostly assembled for a few days now, but I'm struggling to get it to rotate. It'll move freely for a bit, then the wheels will press into the lip on the wall and movement will become difficult. Obviously there's some eccentricity there, but how to solve? I've spent hours tapping walls in and out, loosening and tightening the walls and the dome bolts and have largely gotten nowhere, so I'm wondering if anyone out there has any tips.
