Hi badminton forum, i have a problem I have a crank operated stringing machine at home. Yesterday night i was stringing my Armortec 700 with BG 66 Maxima at 25lbs. After the string the job was done, i checked the racket and the string and everything was fine. I went to sleep afterwards. This morning i woke up and when i was about the get change, i realise the string had burst at around the 10/2 o clock position. This is not the first time that time that this had happened to me. It also happen when i was stringing my friend'a Aeronaut 7000i. I realise that both the Armortec 700 and Aeronaut 7000i had the square kind of grommet installed at the top half of the racket. However, i strung Bg 80 at 25lbs on the armortec 700 and everything fine. Anyone know how to tackle this problem? Thanks!
