try this again-
My OS autoharp has pins at the anchor end. the old existing strings have what look like small washers with a concave grove around the perimiter. The string ends are placed in the grooved washers, and then the washers are placed over the ends of the pins. So-If I use strings without the stress-reliving washers will the strings cut thru the pins? If I get the strings with the Balls the inside diameter is less then the diameter of the pins. Which do I use?
