Presenting a custom record centering accessory, intended as a very quick and simple way of centering vinyl records with oversize center holes.
This compact and lightweight accessory is simply placed on the center spindle of your turntable over the record and twisted, positioning the sharp edge between the spindle and record hole, taking up any excessive clearance.
For some reason, the people involved with the manufacturing of vinyl records are rather stoic types. The rare occasion when they are in a talkative mood, they mostly talk about the manufacturing process and equipment. They are not often talking about what happens after the records have been manufactured, the actual reproduction of these records, for pleasure or for the most critical step of manufacturing: Quality control.
What follows is the story of the restoration, modification, assembly, calibration and testing, of some components, which, if used properly, can result in a highly accurate phonograph disk reproduction system.
