I have a dropweight MP stringer with 6 point mounting. I have strung 40-50 racquets since March of 2008. Twice, I have strung two different racquets. After two jobs, there seemed to be a flaw in the cross strings and how they lay on the stringbed. The middle of the cross strings won't adjust correctly so that they are evenly distributed on the stringbed. One cross string stays higher and the cross string below it stays lower(seems bowed). Even when I try to push them to look right the two cross strings return to their uneveness on the stringbed immediately. I hope I am explaining this okay. I can't do a photo because I don't have enough posts here. I should be able to adjust the two cross strings so they look evenly distributed but I can't. When I push the two strings where they should be they instantly go back to an erratic position. This has happened twice on two different racquets and I am concerned that I am doing something wrong??? Can you please help so I don't destroy my friends racquets? I am very careful when I mount to not tighten too much. I two finger tighten so the racquet doesn't move when I try to rotate the handle. What could be causing this to happen? It seems like these racquets are now warped or deformed. I don't think there was this issue before I strung them? I cut the strings out as per YUlittles video. Please, please help and thank you in advance.
