Colin, if you copy the end shape of a genuine cable exactly and use the original end cap all should be well, I have done so in the past with no issues. I do not believe it would be necessary to modify an austin arm or endocarp to make it work, some modern replacement cables have badly shaped end caps which dig into the ball perhaps this has been the cause of your problems?
