Next try - have found my small drills and drilled out the holes on the end of the spreader arms - its 0.2mm before you ask..
As you can see on the second one its very very easy to break off the ends when drilling, good job I have a few spares. Next job when I have 2 quality ones is to thread he wire through and fix in place -- think its a 50 50 chance of me getting a good job done.
