Craig,
A spring's rate is also dependent upon the type and strength of the material that the spring is make of. The easiest way to determine this is by meassuring non only the items that you mention below but also how much force it takes to compress or expand the spring 1".
I have searched the archives for the original message and can't find it. I have many springs on my LNC2. In the last 10 messages, no-one mentioned which spring it is on which airplane.
Well, which spring it is on which airplane?

Bill Hogarty, a spring rate is pretty much determined by the spring free length, coil diameter, the wire diameter and the number of coils. The modulus for most springs of this type is constant. Get this info from Lancair and look in McMaster Carr or a Lee Spring catalog. They will give you the rate info.
