    I've never had a problem with racket length before and after stringing. I almost always have at least two or more of the same rackets and after I string one, I measure it to the unstrung one. They are always the same length.

    Panda Finding: Electronic Constant Pull (ECP) vs. Crank: tension difference about 3lbs., all other things being equal.

    Way back in the day when I started stringing, I had heard constant pull strung tighter than crank (the reason why made sense). At that time, I calibrated my crank to be about 1.5lbs. higher than it actually was to more closely simulate constant pull (CP). Master PeteLSD told me his experience was, CP vs. Crank was a difference of about 3lbs. After experiencing both, I concur.

    So far I've strung: 2 x new Ti10s, 2 x Cab20s, 2 x Chao Pai NP728s with the Wise and there have been no problems at all. The highest I've strung on the Wise so far is 27.0 x 29.7lbs. (~28.3lbs.) which feels like my crank at about 28.25 x 31.0. (~29.6lbs.). Take into account the 1.5lbs. I added to the crank, that's about 2.8lbs., almost a 3lbs. difference.

    Master Pete is always right when it comes to stringing... :D

    I have two more Cab20s, 1 x SOTX 8080+, 1 x SOTX Woven 8 and a few more CP NP728s to string today...but will tell you the Wise is awesome.

    The grip is the Chao Pai purple tacky overgrip and excellent grip. I'll send you some along with the new Ashaway X1709 aka ZGut string. :D

    I cannot assess this at this time because every time the Wise pulls, panda goes "Ohhhhh!!! Ahhhhhh!!! Woooow!!! Shiiiiiney!!!" and cannot even hear the machine. :p

    It's definitely not loud, I'd say it's OK, definitely bear...bareable.

    So, I take it you're happy with it? ;)

    glad to see less people having complications with it... (after some terrifying posts on tennis-stringer-fora) good news!

    some more questions.. How does the string-clamp work, did you need to adjust it?
    I also read you cp728 sell-post...
    are you stringer two-piece, top-bottom now? Is it because of the wise?
    (curious lad, aren't I? :p)

    Yes, I'm very pleased with the Wise. It's an extremely consistent machine. There are only three minor gripes I have:

    1) The gripper at even the tightest setting is not sufficient for badminton string. I added a piece of leather grip and it's just fine now.

    2) The control panel is a quality plastic but it's secured by industrial two sided tape. :eek: On both edges, the panel kind of lifts up and I have to push down every now and then. The plastic panel won't come off but it's just funny when it sticks up...doesn't exactly instill confidence. :p

    3) I wish the gripper was closer to the edge of the machine, that way I could still get away with my normal pre-string method. Now I'm in the same boat as most of you stringers needing extra length on the two middle loops to start pulling. It's a minor pain but well worth the performance return I get from electronic constant pull (ECP).

    I now only string 2PTD (2-Piece Top Down). I find the string job is more uniform, more crisp and the upper half of the string bed is just more responsive.

    Also, the 2nd most important factor (next to more crisp/responsive) for me is going top down, I don't put as much stress on the final tie-off. I'd rather do 34lbs. on the bottom tie-off than the top one (add 2-3lbs. to offset the tension loss).

    For pro stringers and players that are very sensitive to string tension differences, ECP is significantly better than crank. I highly recommend ECP if you need it or your performance goals demand it. :)

    That was extensive, thanks..a good read..

    so you're done pre-stringing as well?
    My tensioner is also quite far away from the supports. I use two loops at the beginning as well (costs me a some extra string, but is well worth it)

    ;) happy me the local tension range is 24-25lbs.. My 27-28lbs often comes across as "insane" :p

    Thanks, for all the answers!

    I still pre-string. But I need the extra length for the two loops so what I do is do a normal pre-string, then pull out the last main and move all that string back to center and now I have just enough.

    I know some others tie the string around the shaft but I don't want to risk damaging the string.

    In the last 3 months I've started going higher and higher in tension. As a result, I play better and better. 3 months ago I was at 26-27lbs. Now I'm at 30-32lbs. :p The 30-32lbs. is constant pull, not crank. If I keep playing better at higher tensions, I might try Jens Erikson's 35lbs. :eek:

    what the hell?! such a high tension you string at... kind of scares me lol. I get scared when I go to 26/27.

    Ahhhh, no worries, it's a piece of cake. I will do a 2PTD stringing video at 30x32lbs. ... maybe in a few hours from now. :D

    tying around the shaft? I don't follow... How/why/when?

    I just tried 36lbs once, on a w7, for fun... Never got around to playing a serious match with it..
    Frankly, I tend to have some mishits issues (even) at 28lbs...
    I'm not too proud to admit it:p but I guess it's because I'm hitting harder, and have to hit hard under pressure more..

    What really brings my piss to a boil is that out of all the mishits I break strings with, 90% are midcourt kills...:eek:

    I can't imagine how many strings I'd use up with 35lbs...

    Come on Jerry, you are or should be an expert stringer and should understand. :p

    OK, when I do the pre-string normally, I loop one of the mains around the butt of the racket right? Well, that's not enough string for this new machine because the gripper is too far away. I know a few that do two loops but that doesn't leave enough string to pre-string the last 5 or so cross strings.

    Now I know a few more that do two equidistant loops that are longer but the loops are not taut and it makes pre-weaving the crosses very difficult. So what they do is tie the two loops around the shaft. It works for them but for me, I worry about damaging the string.

    Make sense now? :p

    yeah, crystal :)

    I was thinking of different knots..my bad...:eek:

    For me, I juts cut 5,5-6 armlength and it works perfectly.. Two loops around the butt-end and finished..
    I have no idea how long that is though :p

    Expert stringer? meh... I think I know how it works, but expert is a big word :p.. But stringing isn't rocket science ;)

    EDIT:
    okay, I span 190cm, so I use ~10,5m... Not as bad as I thought..

    Don't know about the Eagnas machines but the Wise is definitely a true constant pull.

    For me, I use 6 wingspan lengths (your "arm lengths") and it's spot on. Another way is to use 14 racket lengths. However, that's not the point or problem. The problem is, if you use two loops, there will be too much excess string on the first tie-off. Also, you should not have enough string to pre-weave all the crosses until you start the crosses. And if you do have enough string, you are going over 33' and wasting string.

    Anyway, I bet a few pictures would be worth a thousand words. :p

    yeah, I tried to take a pic... but my computer crashed when I plugged in the webcam :|
    darn free-webcam.. everybody I know who got one has the same blue-screen-of-death issue...

    anyway, I do indeed waste some string, I guess on the first tie off (the 'short' side mains) i throw away one of two feet of string...

    But that roughly translates itself into ~1dollar per string job...
    well worth it not having to plow through those nasty holes at bottom #12, #10, or that pesky #11 which is always blocked by a string...
