    Could anybody tell me whether manufacturers' recommended tension ranges are based on stringing on manual "instant off" machines or electronic "constant pull" machines?? :oops:

    I don't think it really matters since you could string outside those parameters with no risk of frame damage (ouside by a little, say a couple of pounds, not alot say 15 lbs)

    Most likely manual machines. electronic machines usually require decrease of ~10lbs to achieve desired tension.

    Plus, they have to figure more than 90% of all stringers use a manual pull of some kind.

    I'm reviving this thread to see if axle's comment can be corroborated. According to TW's Learning Center:

    It also tells us there are two kinds of tension and they are:

    and

    So question is which one do manufacturers' recommended tension ranges refer to: 1) actual tension, 2) reference tension strung on a continuous pull machine, or 3) reference tension strung on a lockout machine? There are big differences among these and warranties and apparently playability are at stake here, aren't they?

    I got the answer from Wilson myself. Think you guys might be interested as well...

    NO difference...

    The manufacturers don't make a distinction as to what type of stringing machine is used. Head size and string pattern have a lot to do with tension ranges, however. A 95 sqin racquet with a pattern of 16X20 pattern will likely have a higer max tension than a racquet with a pattern of 18X20. MOre strings equals more overall stress on the frame.

    A racquet like the POG OS can take a lot of tension. I string mine at 70 with no problem. It's a large head which means the string length is longer. A long string at 70 pounds is less stressful than a short string at 70 lbs.

    So there are a lot of factors that a manufacturer considers when setting the tension range.

    This doesn't include ranges for racquets like the PD (Woofer) or the Catapult series. These ranges are set to allow the grommets to do their thing. Above or below the tension range and the Woofer/Catapult won't function properly.
