The Turntable is free to rotate on the groundboard riding on the 3 PTFE pads. A ball bearing is fitted in the centre. The movement over the PTFE provides the ‘push to’ slip clutch action in azimuth. Note the circular groove ready to take the lazy susan bearing. The turntable is 18mm thick, and has a small 3mm lip at the bottom. A 15mm wide toothed belt fits around its rim and no teeth are needed on the turntable as there is enough friction between belt and turntable.
