The front-mounted turning wheel makes this mill equally comfortable to operate standing or sitting, while the ultra-high gear reduction means 50 handwheel turns produce just one roll revolution — dramatically reducing the effort required for each pass. Built on a solid single cast body with induction-hardened rolls and Durston's highly calibrated adjustment wheel, the Molly F165 is engineered for precision, repeatability, and long-term durability in a professional studio.\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50:1 reduction gearbox (patent pending)\u003c\/strong\u003e – 50
