The Flexure. It is an updated version of the original Tron machine. Built to work long and hard all day, every day. It’s a simple idea where the conrod now has a 'flexure' set into it instead of being a solid piece. This gives the machine a solid hit as it flexes back down, but also a lovely bit of give in the machine like a coil. Comes with both 2.5mm and 3.5mm cam and a medium and hard Flexure conrod to swap and choose your ideal set up.- Works with standard needles or cartridges.- Great for solid colour packing, shade and line work. - Hard hitting and can be run slow or fast.- Weight: Made from aluminium with brass parts it weighs 119g(4.1oz) with the tensioner and 109g(3.8oz) without the tensioner. - 2.5mm cam which gives it about 3.2mm of travel (pushes singles to 9L, great for black and grey, colour work and stippling).- 3.5mm cam which gives it about 4.5mm of travel (pushes singles to 18rl, great for solid colour/blackwork, whip shading and stippling). - 12v brushless motor.- Optimal running voltage 5-9v and RCA only.
