My homemade turntable. Weighing 200 kilos. The chasis is made from lead.crushed granite and slate
mixed with epoxy resin.The platter is laminated from steel and PVC and weighs 38 kilos. The motor is a 24v dc with skewed armature driving a 10 kilo flywheel which runs at 600rpm,this drives the platter.The armtube is made from one piece of solid aluminium,and retained in a massive steel bearing housing.
This took 3 years 6 months to make.
