Loosening up specs can boost spring precision. Spring rate remains about linear (Hooke's Law) until gradual coil dampening and loss boost rate. Make free length a reference dimension so spring makers ...

How efficiently and effectively a workpiece is heated is determined by the design and type of the induction coil. Work coils range in complexity from a simple solenoid- or helical-wound coil (made up ...
