Hi Dave, there are several different measurements that you have to track, and some bench marks that you have to establish... first one, is wire diamater... second, new free length, (uncompressed as new)...third, pounds of force at 1" compressed, pounds of force at full compression....fourth, measure overall dia. of spring when in free length state...

Second group of measurements, first, free length after 20 complete cycles to solid, (measuring set) ... second, measure spring dia. after 20 complete cycles to solid, (again measuring set)... Third, pounds of force at full compression, ( measuring the effects of set) ... Find the best spring for your needs out of the test batches.. and then confine your future testing to using that spring... Best to you, til...lat'r...GT
