I have been using total number of coils (N) times wire diameter (d) to get solid height. This appears too conservative for our application. We are trying to pack more spring into a limited space. We have been able to add several shims to the existing spring, which calculations say there is no room for.
The spring is squared and ground on both ends. Would it be more reasonable to assume half a coil is lost on each end, so that the solid height would be (N-1)d?
Thanks, John Woodward
