    Wow, this is mind boggling.

    According to the page that Bill posted, the rate would [edit]increase[/edit] (I need a math lesson) if you removed coils with everything else being the same.
    RATE and PRELOAD are two different things.

    Preloading a spring means that a force proportionate or greater to the preload is needed to compress or stretch the spring further.

    Rate is how much stronger the resistance a spring will give as it is compressed.

    Confused yet??

    Spring rate can be linear or progressive. A linear rate means the resistance remains relatively even as the spring is compressed. Progressive means the resistance increases at a progressive rate as the spring is compressed. (ie the more you push/pull, the greater the resistance)

    It REALLY get confusing with a spring with LINEAR and PROGRESSIVE rates wound into ONE SPRING! (look for tightly wound and loosely wound coils in the same spring.

    I'm bad with the math, so dont ask. I have a headache!
    All this spring knowledge I've gained with bicycle suspension work. (spring rates and preload are CRUCIAL in mountain bike suspension tuning)

        I've ordered springs from Mcmaster Carr. Their website will help you figure out what you need. I glanced at the site and saw one for 60 lbs. with hooks on the end. It was a pretty big spring.

          I dont have a clue about what I was working on.

            Some of the links in here didn't work when trying to open. I did find a spot that had extensive information for small springs, medium springs, and very large industrial springs. This site has a Request For Quote feature which can be sent to many spring manufacturers all at once, so it won't take much of your time to contact more than one manufacturer/supplier. I'd send out a question like this in the RFQ and you might get several quick replies, faster and more reliable information than here.

              Good job! You brought it back to life! It's a zombie thread now. It's cool how the web team never deleted this, but it is a good resource for us visitors who are looking for references/help.

                He was remarking about a spam post (since deleted) that resurrected the thread. He didn't.

                Spam should be reported with the report button, and NOT replied to, further bumping it.
