Can someone tell me what is minimum lenght of string needed to string a recket (2 pieces 4 knot)? I bought a yonex 500m reel of string and i try to calculate how can I string as many recket as possible. My calculation tell me that for main 440cm and for cross 415cm should be enough to string a recket. Is that rihgt? If thats enough i could string 58 recket with 500m reel. I use eagnas crank st-200 machine.
Your question depends a little bit on the string tension, how high you go. The safest way is to measure out 33 feet. If you use higher tension, you can go 32 feet. I normally do a one-piece, two-knot at 26/29lbs. and I only need 29-30 feet.
I second Sir DinkALot. If you want to save string, do 1 piece method. Since YY is ok with starting cross from bottom now.
Papak didn't mention the racket type. Starting the cross from the bottom makes sense regardless of Yonex's "approval". The T-joint area is the strongest part of the racket frame, while the top of the from is the weakest. It should make sense to start at the bottom, at least to me. I guess with Yonex's "approval", more people are "OK" with it.
What I do is to measure about 8 rackets length for each piece of string, thus 16 rackets for a 2 piece string job. I usually found about 1 racket length of string left after a 25lbs job, so DinkAlot is right for measuring about 32 feets for each racket, and 31 feets should do too but at your own risk.
For 2 piece stringing I always measure 7.5 racket lengths for the mains & 6.5 racket lengths for the crosses. When you get used to certain rackets you can reduce these amounts a little bit more, but be careful not to reduce too much or you will have insufficient to tie off at the end. RAMADA77
Thanx for answering my question ppl. I strung mostly YY reckets 80% and some Victor reckets. Tenison is max @25lb becouse I strung reckets on club level. I could string a recket in 1 piece but i read many topics on this forum that says, that 2 piece stringing is better and faster.
Personally, my own minimal length (w/o taking too much risk) will be at least 9m. You need a few inches extra here and there to tension the last pieces (main or cross). To further squeeze the extra 0.3m or so, will give me only headaches rather than savings.
We must not also forget that Yonex specify that 2 piece stringing should be used with all their rackets. I believe this can affect the warranty on the racket if rackets are returned due to a problem and are seen to have been strung incorrectly. This is what seems to happen in the UK. Best to cut out the strings first before returning if you do have a problem with the frame etc. RAMADA 77
Fair point Not sure if that is the case in the UK, but it may well now be ! I was told this a couple of years ago particularly when the string was tensioned slightly higher than that recommended. I suppose you cannot blame them really. RAMADA77
What's the precise lenght for crosses amd mains? After all, what should be the exact lenght (in meters or feets) for crosses and mains, in a 4 knots stringing?
Please be more specific. Are you asking a) min main and cross string length to string a racquet b) string length of main and cross string after stringing The answer depend on racquet type and model. Also depend on the machine you use. Are you using starting clamp or string extension. Also depend on the tension (not to much).
Last Year I mostly strung a Yonex (MP, Armortec, NS) racquets and came to this: For main I needed 490cm and for crosses 400cm. Stringing tension between 10-13kg. So I strung 56 racquets with 500m reel
I don't mind to see ppl doing this as for an experiement, as well as save a few $$$ here and there. However, I highly NOT recommend to squeeze to the last inch in order to string a racket. Yeah, you might save about 10% on material cost, but remember, 500m reel compare to single package already save you quite a few. How much more you can save, from the extra 10%. At the same time, you need to deal with all the extra headache, and how frustrated you will feel, if you are up to the last piece of tension, and you are quite a few inches short? I know there's method you can work aroud to save yourself out of the situation, but the frustration and lackness of quality (never to metion, less experienced stringer will simply waste a job) not worth the extra $1. To me, if you want to focus on the quality of job, and enjoy the process, just bulk order the single packages. At the end, the difference in price is very minimal. However, you saved tons of time and effort, and have more time to have fun.
What I want to know its not how to use the less strenght possible, but with 10 meters of string, to string a Yonex AT 500, using the 4 knots technic with a tension of 24 lbs. In this case, how much should I have for crosses and how much should I have for mains?
For your AT500. If you have a drop weight machine, to be safe, 9.25m is needed (5.25m main and 4m cross). If you have starting clamp or use string extension (by clamp 1 main string to 1 side of fly clamp and an extra string to the other side of fly clamp) 9m (5m main and 4m cross) will do. My suggestion is to string the main first without cutting the string. After you tide off the mains, cut the string. This way, you will get the extra 25~30cm. For hand crank and electric machine, 9m will be enough. Same method.
