As part of a set up on a used on a less expensive Fender banjo I tightened the Remo head. I used my US made inch-pounds torque wrench. I proceeded slowly form the initial readings of near zero. My goal was 12-13 inch-pounds. I got it at/near 10 inch pounds and left it over-night. The next day the readings had dropped to 5-7.5 inch pounds and I resumed tightening.Again, proceeding slowly. I got it back to 10 inch-pounds with no sounds of concern. To my ear it still was not near an A. I left it for a few minutes and while it was just sitting that horrible sound occurred.On inspection I could see the head had split at the usual place, where it goes into the rim. I have yet to dissable the banjo so I don't know if there is a sharp edge/or other cause for the head splitting. In my mind and my heart I know I did nothing wrong. So, form my standpoint I should not have to absorb the cost of a new head and installation. But, from the standpoint of the owner the cost of installing a new head was not expected. (Nor did I even mention this as a possible additional cost above the estimate for the set up.)
In my many years in business I have not had this happen before. Have any of you? What did you do?
Even if you have not had this occur what is your opinion and why?
