    Like the title said. No matter how many time i restring I keep getting an oval shape, which mean it's fatter than other restring.
    Shorter and fatter.
    please help
    I think I did everything correctly,
    Just maybe I clamp down the racquet too tight.
    Would that be the problem?
    Thank you
    really please help

    I've strung with armortec 900T and arcsaber 7, armortec 700
    All three got the big fat face.
    and my method is 2 pieces.
    I string the main first. go two side, which mean side by side. (left right left right)
    And then after tide off the the string, I go with the cross.
    I go from bottom to up.
    Make a knot at B6 and then just pull it from line 9 (B9) to all the way up just like yonex recommend.
    I did try 50/50 for cross too. However, both method I use I get the fat face.

    make sure you have the north/south poles (two ends) are securely pushed against the frame prior to stringing.

    I have all that points 10 percent more yes. And my machine is easy 3 from eagnas. I think I might have tight down the clamps too hard for securing the racquet.

    Not strung properly. Perhaps you can add the 10% more tension on the cross. Personally I do not, but my rackets are not oval shaped hahah.

    thank you Enig.Ma, yes i did add 10%, in fact I did say that before you posted it.

    Anyway, I think I've finally find out the reason why I've been getting the oval shaped.
    Reason is I've been tighting down the side clamps too hard, that secure the racquet shape stay still. However, the long side (the main) got shrink in because there's no clamp to secure it.

    sorry I'm not high tech enough to have a cam.
    But anyhow, I think I make it less and less oval, I might have to be more detail on the cross. Gotta keep re-clamp the 4 side once the frame move in.

    Because, before I tight those 4 clamps too tight, and I do not see any frame able to move in any bit.
    Now I'm getting better at it. And it's moving in slowly, however, I just finished one of my racquet, and it still have tiny bit of oval shape. Not perfect string job yet, but yes improve from before.

    Possibly "cranking" too quickly to cause frame deflection.

    Not all cross 10% more, the bottom 4 and top 5 do not need 10% more. And what tension are you acturally doing?

    Have you compared an unstrung frame to a strung frame (same model and make)? Is there a difference in width and height of both?

    Did you use a socket wrench to tighten the knobs :D?

    if you get oval/fat face then your north south are too loose when you start.

    From what Illusionistpro, he was right, my north and south were too loose.

    Well I just did 2 racquets, same technique, different tension.
    1 = 29 & 31

    2 = 26 & 28

    Yes both of them is getting better, obviously the one with less tension it has a longer length of the main.

    However, I wonder if badder idea was right, botton 4 lines and top 5 lines doesn't need 10%, that would make the middle of the racquet (cross) would get smaller than the whole thing being 10%.

    Interesting, i'll try that on the next racquet.

    Thank you for the replies people.
    Much thank you. Learning new stuffs makes me feel good.

    OMG!
    The more i read the more confused I get.
    Seriously, I mean from the last posted, I think I HAD it down.

    So let me rewrite the whole thing from what I've learn and experienced.

    1st, I mount my racquet on the machine, (OH AND YES MY MOUNTING MACHINE IS LOOKS LIKE THAT PICTURE, special thanks to PETELSD) I tight the TOP and BOTTOM REALLY tight, so that when i put 28 lbs it doesn't shrink down my main as much. Because if it shrink down too much it will gets fatter.

    2nd, for the 4 clamps on the side, I do not even tight them down, all I do is just put it in place to have the support that it will not bend up or bend down when I pulling the cross, if it shrink, but at least it doesn't have the possibility to move up or down motion.

    3rd, well pretty much when i take it out, it still have a little of fat face but well like I said it's better than before, I didn't tight down the top and bottom knob tight enough.

    PLEASE! whoever, have string machine and had great amount of experience on stringing. Please please and please, give me some input. This forum is about helping out not just reading it for fun and oh well not my problem.
