Made from aluminium and designed with intricate cutting projects in mind, they are the number one choice for the professional workshop and are produced in the USA (US Patent Code #8,347,513) Standard Tensions Screw 3" Frame This is the basic Knew Concept Saw Frame with a standard tension screw lock to hold the blade in place. Ideally suited to hold a standard 130mm jewellers saw blade, even including a blade ruler in the frame to make checking blade length super simple. It is also possible to move the clamping mechanisms for left handed use. Loosing and Removing Loosen the tension EVERY time you remove a blade, before placing a new blade in both blade clamps. It usually needs to be loosened with two or three turns. CAUTION: Too much loosening will allow the blade clamp to fall out of the saw. Tensioning The knurled brass knob is the tensioning mechanism (known as the tensioning knob). To increase tension, screw 'in' towards the blade clamping screw. To release tension, screw 'ot' away from the blade clamping screw. The know must be unscrewed slightly to reset tension during blade changes. After clamping a new blade, twist the knob to return tension to desired level. ## Features - KNEW CONCEPT FRET SAW FRAME: Choose from our range of Knew Concept Aluminium Jewellers Saw Frames, designed for jeweller's, metal smiths and carpenters who require precision, neat cuts - ALMOST WEIGHTLESS: The frame is made of aluminum and the innovative structure of the frame makes the entire saw rigid but easy to control. - STANDARD 3" FRAME: Includes a tension screw locking mechanism - FREE BLADE WITH EACH SAW: Get a free quality blade with every saw.
