DIY Vacuum Record Cleaning Machine

a DIY record vacuum cleaning machine the case is made of perspex, cut using a CNC router. the vacuum motor was salvaged from a Sanyo 1600W vacuum cleaner bought from a thrift store, it is hooked up to a motor speed control card that limits the power of the vacuum. the platter and clamp is also made out of perspex, but the clamp is way too light to turn the record during the vacuum phase. i guess an addition of some weights would solve that problem but for now I have to manually use my hands to turn the record at the edges. the vacuum nozzle is made from simple PVC pipes with high quality velvet attached to the mouth. the record cleaning fluid is also DIY, made with 3 parts deionised water, 1 part isopropyl alcohol and 1 drop of dishwashing fluid. the brush is a good quality wet cleaning brush with sturdy nylon bristles to get the grit and muck out of the grooves and the vacuum will suck that all away. the record is already very scratched to begin with and cleaning it
