Has anyone using the Wise 2086 tensioner noticed damage to the gripper plate(s) as received from the supplier, and if yes what did you do about it? I just received mine direct from H. and when I dismantled the gripper for cleaning (the inner gripping surfaces were quite dirty as received), I noticed some dents and dings on one of the gripper plates. I'm concerned that these imperfections in the gripping surface will damage the string coating (as they project above the gripping plane), especially when stringing at high tension (>24 lbs) with thin string (< 0.66mm). The dents are small and are hard to see with the naked eye, however they are very obvious using 10X magnification. The dents are in close proximity to the 2 pins that are inserted into the plate, so I'm thinking they may be occuring when the pins are inserted at the factory.
