    This is a question for owners of the Star 5 and prior owners of the Star 3.

    Q1: If the string bed tighter on the Star 5 than the Star 3, if both are strong at the same identical tension?


    Q2: My Star 3 seems to hold calibration very well. Is that true with the Star 5 as well?


    I think Albert Lee has both of these machines. I'm sure there are other stringers too.

    I don't own a Star 3, but my Star 5 holds calibration perfectly. I'm not aware of any issues in this regard.

    If there is a difference in tension, I might invoke the newer clamps with less wear on the Star5.

    My understanding is that the newer machines (star5, sensor, etc) over shoot their tension. I believe Albert Lee alluded to this in one of his posts. How much they overshoot, I'm not sure.

    new machines do overshoot their tension, at least the ones I know of (Babolat Star 5, Sensor, Prince machines, not sure on the Wilson Bairado)

    I believe the general rule I have seen is that the newer Babolat and Prince machines are around 10% overshoot

    An overshoot is not the same as overtensioning the string, it's nothing more than a prestretch before returning to the spec tension.

    Star 3 and Star 5 Comments

    Q1: Is the string bed tighter on the Star 5 than the Star 3, if both are strong at the same identical tension?

    With calibrated machines, the Star 5 strings tighter than the Star3. As mentioned in earlier messages, the Star 5 overshoots reference (read this as a mini prestretch) by +8 before returning to reference. This is measured with a Shimpo Lab Reference peak reading Force gauge.

    The Star 3 does not overshoot reference.

    Q2: My Star 3 seems to hold calibration very well. Is that true with the Star 5 as well?

    Yes, both machines are very stable, though I recommend you check calibration if you move the machine. I also recommend you connect the machines' power cord to a Uninteruptable Power Supply (UPS). Both machines have robust power supplies, but it is always easier to protect them than to replace them.

    Overshoot = Prestretch.
    - Does that mean we would not need to prestrech for gut on the Babolat 5?


    UPS .... That's a great idea. Certainly well worth the investment!

    The Star 3 has been troublefree for so long. Its an amazing workhorse. Any repairs/maintenace are minimal in cost. I wondering if the Star 5 would have the same longevity and cost point for repair? Of course this exclude any electronic repairs.
