I just came up this idea and tried it. Looks it is working. Here is what I did.... First I cut a piano wire at right lengths and put 'HEAT Shrink Tubes'.... And then, glued using 'CA'. Since the glue surface is kind of 'ruber', the bonding was quite strong.... Compared to old one... Finally, it is painted.... Well, yes.. It is not white... I had a diffulity to paint with brush. So, this time, I sprayed. At this moment, 'gray' was only one I have in spray... Spray gave smoother paint surface..
