Why we made this The Synth is a light, affordable pedal with all the features, using injection molded composite material Key Features ☛ Injection moulded with concave surface that is only 15mm at center☛ 18 height adjustable traction pins/pedal with alternate placement holes☛ G3 Axle system featuring hardened chromoly axle, dual seals, inner bushing and precision cartridge bearing Materials & Construction ☛ Polycarbonate/nylon body☛ Precision ground, hardened chromoly axle☛ Low friction metal bushing☛ Cartridge bearing Specs Profile // Concave Design, 15.0mm at platform center Material // Polycarbonate / Nylon Platform // 110mm x 107mm Stance // 60mm Pins // 18 per pedal Weight // 380g/pair CNC Machining CNC Machining is a process in which a piece of raw material or stock is cut into a final desired shape using a computer controlled machine and often several different machine tools. Depending on the operation in question different tools are called, for example ball mills, end mills, thread mills, taps and slitting saws to name a few, all have different uses and come in all manner of shapes and sizes.Machining produces extremely accurate parts, often to within 0.001" (I know, Canada is mostly metric but the industry predominately uses imperial units), and is renowned for creating a very high-end look with 3D surfacing and clean, strong edges which forging cannot produce.Because every aspect of the part must be "cut out" machined parts take a long time to produce. A Ranger body for example takes 20 minutes to machine (the face plate is made separately), then it still needs to be deburred, quality checked, anodised, laser etched and assembled.
