Sorry for the delay in reply but I had other projects to attend too, including a clock repair that was a Xmas present so the blessing clock had to be put to one side. I did try the cable tie method but it did not work for me (although I was getting fed up at the time). However I have another idea that might work. I have purchased today some small metal curtain rings and I think I will be able to make small C spring clamps from them that will fit this job. I will post if this works but this will not be till after the festive season.
