[Mr Innovative] needed to wind some coils, and decided to make a machine to do the work. Making such machines has become a lot easier over the years. There was a time when we might probably have had ...

Spring technology for damping is relatively old. Stagecoaches had leaf springs, early trains had large, crude, coil-spring buffers (to absorb shocks when cars bumped together) and early automobiles ...

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 can adjust it as needed to obtain load at a ...
