The turntable consists of two separate massive plywood-blocks (glued together from boards). One supports the platter and tonearm (main base), the second supports the motor (motor base). The platter is driven by a simple thread out of mom's sewing box. This way the motor is decoupled from the main base.
Between the main base and the motor base, there's a gap. By moving the motor base away from the main base, you can adjust thread tension



This gives you the look & feel of a broadminded one-piece turntable - with lots of space for laying accessories like brushes, stylus protector, bottle beer etc. - but the advantage of having a separate decoupled motor base.
