My preference for capo bars is a question mark. The best system I have seen is that of the SD-10 and the SF-10 Baldwins. 1/16" seems about right. Next chance I get I'll measure it. I have dressed many capo bars in my time but I have to say that my motivation for my method has been lacking until recently. If have have gotten good results it has probably been more the result of chance than that of calculation. I have also probably created more problems than I have fixed. Several years ago I felt proud to have discovered a roughly cast capo that had not been dressed at all in a Steinway D from the mid sixties. I was going to get it right I carefully filed and checked and refiled then continued dressing the bar with various grades of emery cloth. This piano was going to be so improved! I had been tuning it for nearly ten years. When all was put back together it did sound better than it had but it was still a big letdown. The capo section was full of zingers. I tried the big Robinson lever and numerous other remedies all to no avail. IN the end we jammed little mutes in duplex which killed the zingers and the sound. Now about three years later it is sounding better and many of the zingers have disappeared probably due to the factors mentioned in my last post to Piano Tech. Michael Wathen
