I just got a call from the ski shop where I had taken my skis to be tuned. They sais that they had put a hole through my bases. When I called back the manager gave me a slightly different story say that you could see through the base, but that it was not all the way through. He insisted that this was normal and that there is no way for the shop to know that this will happen prior to the grinding.
My question; is this normal? Is there really no way for them to tell how much base is left?
