Just a couple questions from me, if someone knows
1. If you're inserting the English thread coil into Italian threads, then that goes in clockwise. When you then thread in the English cup anticlockwise, it will never satisfactorily tighten as the coil will undo. This leads me to think that the coil has to be somehow "fixed" in. Is that correct?
2. Why do those threadless units have a bevel on, thus needing the frame to be chamfered on the edges. If it was made without the bevel, it would make installation a simple DIY job. There must be a sound reason
