I’d like to talk about a basic, technical discussion on polishing machines without forced delivery. The all-round and rightly popular Kestrel DAS-6 and its derivatives are offered by various providers in different versions, e.g. as Kestrel DAS-6 and DAS-6 Pro or as Liquid Elements Tornado T2000 and T3000. The main difference between the machines is the power consumption and the price – the “small” machines pull about 500 watts, the “large” around 800 watts. Machines without forced delivery have a slip clutch in their drive, which ensures that the polisher stays at high load, while the machine continues to run. The actual drive is done to my knowledge on an excenter weight behind the clutch, which, so to speak, rips the polisher away. If this excenter weight is the same with the “small” and the “large” machine, then I think the 300 watts of the “large” machine in the Nirvana is coming to the point. The “big” machine only brings a benefit to this forum?
