So, my first time ever stringing was a failure. I had my klippermate on my coffee table, measured out 21' for the mains for my agassi radical racket, and ran out of string. I guess 22' is what I should have used, even though the klippermate guy gave me the stringing specs which had the mains listed at 21'!!!! Being hunched over my coffee table trying to string for the first time, KILLED my back. Anyhow my main problem is that while stringing, and using the clamps, it seems like when I attach the clamp, and then raise the tension bar, the strings are losing their tension a bit. Is this normal, is there something I am doing wrong?
