You say you tuned at 50 c flat, and then 40 c flat. That would indicate it isn't going any where. What you want to do is measure the width of the crack at several places, but mostly at the ends. Also, draw a line at each end where the crack ends. Next year, see if there is an increase in the length of the crack and the width. If it hasn't gone any where, then this is an old crack, and there will be no need to fix it. Wim </HTML>
