    Hi,

    I recently purchased a Gamma x2 to dip my toe into the stringing word, but i'm having some problems. I have read countless threads, and watching youtube a fair bit aswell. My problems are mainly

    1. Finishing Knot - I'm having real problems here. I cant seem to get the knot tight up against the frame. The cinching motion doesn't seems to work for me, and i'm losing a lot of tension. Any tips? (i'm using pro's pro nano vendetta. Seems like a stiff-ish poly)

    2. Tension on middle main strings. I seem to have this pretty good at the beginning, but after finishing the mains the tension seems to much much lower. This is probably related to problem one though?

    3. Also when stringing the mains on some strings (not all) when I release the clamp after tensioning the tension arm drops a alot (about 20 degrees). What could be the problem here?

    Also should mention that i'm practicing on a 10 year old prince OS raquet.

    Hopefully someone can point me in the right direction as i'm starting to think this machine was a waste of money.

    Thanks

    1. What finishing knot are you using?

    2. Even if you're losing tension on the outermost mains when you tie off, it shouldn't affect the whole string bed. All string jobs start losing tension the moment they're done, but sounds like yours are losing more than they should. Could be related to problem 1 but more so I would think to # 3. All that matters is that you're able to string consistently, so that when you string at a certain tension, it's always the same, not that it necessarily has to come out at that tension.

    3. Are your clamps tight enough? If the string is slipping, this will happen. For example, say you're stringing at 55 lbs, but you're clamps are slipping and only really holding to about 45lbs. Well then every time you pull tension at 55lbs, you're pulling tension not only on the most recently strung main, but also pulling residual slack on the previous one.

    I strung on my trust X-2 for a solid 4 years before upgrading, so I think I can help here.

    Do you use a half-hitch or likeminded knot?

    This should help:

    That happens on constant-pull stringers, there will be some slack when you release the clamp.

    Overall, pretty easy to fix problems. I wouldn't worry too much.

    I have tried both the pro & parnell knots. I think its the the cinching part I cant get.

    I thought my clamps are tight enough, but maybe not. I'll check tonight.

    Thanks for the response. Much appreciated.

    Thanks for the response. I've have seen the first video numerous times, but cant seem to get the cinching motion. He makes it seem so easy on the video. Could it be the stiff string i'm using?

    The second video seems interesting. I'll try this on the weekend.

    If I were you I would invest in a Stringway triple clamp. I have no practical experience with them but the concept make a lot of seance to me. String the center mains as you normally would except for the two outside mains on each side. Then string the outside main and hold it with the triple clamp. Because this clamp holds three strings you may need something in the clamp for a center string. Then string the next to outside main last (unless tour main tie on that strng.) assuming you're ending at the bottom of the frame on the mains the two strings on the outside of the frame are held solid by the throat section of the frame and (almost) can't go up any. The next to the outside main (main 8 in an 18 main racket) wants to pull up but can't because it is held on each side by and string held down.

    Eliminating drawback as much as you can due to clamp twist goes a long way into eliminating tension loss. With two string hold the clamp down on the outsides of the clamp and the center string pulling up there should be no twisting at all.

    Another way to make sure you knot are good is to use something to hold the string to give you as good a grip as possible. Mind you when you have a mechanical advantage it is much easier to break the string tying the knot so be careful. The best three tools you could use for a better grip would be 1) Cam action pliers, 2) Starting clamp, and 3) your other flying clamp.

    Two tips:
    1) Before even tying the knot, make sure you've pulled the string through as much as possible so there's minimal extra slack on the outside of the frame.

    2) When you tie your Parnell knot, you have to cinch up the knot in two parts. You can't expect to tie the knot, cinch up on the tail to get it flush to the frame. You have to cinch the loop, then the tail, but I guess that was shown on the video.

    Yes, stiff poly is much harder to get tight than a soft string. Honestly don't worry if you're losing a little tension, it's not a big deal. Also, some people up the lbs of their outside mains by 10% to compensate for the loss of tension when tying the knots.

    Thanks for the response guys. Much appreciated.

    Well I tried stringing some synthetic gut last night (first non poly string I have attempted) and it was so much easier. Still had a little trouble with the knot tying, but so much easier to string the synthetic gut. Maybe I'll stay away from poly until I'm a bit more experienced.

    Thanks again.

    Cinch the loop AND the tail? At the same time?

    Try a soft poly like Gamma RZR Rx

    No do not try to tighten both at the same time.

    As Irvin just said, no. Cinch the loop, THEN the tail.

    Thanks for the replies.

    i Strung my main racquet for the first time tonight. Went ok actually. Quite pleased with the outcome.

    I went with a hybrid of Solinco tour bite@ 53lbs in the mains and prince Syn gut @ 55lbs in the crosses.

    Knots still give me a little trouble, but I went a suggestion of increasing the tension n the last string by 10%. Seemed to work quite well. I know a lot people say this isn't needed, but until I get better at the knots I'm going to stick with this method.

    Can't wait to hit with the new setup. Hopefully Friday, weather permitting. It is the uk after all lol.

    In response to #3, I use a dropweight stringer and to stay consistent while stringing, I always set the arrow on the tensioning head hub just to the left of center ( horizontal bar will be slightly above horizontal.) This way, when slack comes out of the string, the string will increase in tension and the tensioner shows less motion. What's most important though is to do it the same way every time.
