The knob turns but nothing happens. The Stage(platform) moves up and down, independent of the knob rotation. The base seems to be fixed permanently and still cannot figure out how to remove to get an access to rack&pinion assembly.

ApprenticeNot really a solution, but anything is better than a posting that get's NO response. It sounds like the rack and pinion drive has collapsed. If you're good with your hands and have a knack for things mechanical maybe you can dissassemble the stage mounting and see how it's meant to work. If something has come loose rather than broken maybe you can fix it. If teeth have stripped from the drive gear - you may be unable to effect a repair. I guess trying to fix it is better than doing nothing. Have a good 2008
