I think it is worth doing, many years ago, struggling to get the top off of a box of talc to unblock it, I dropped the whole box on the carpet.When hoovering it up I was surprised at the amount of static that was generated but also the heat on the suction pipe. So although generally shavings are not as fine as the dustI would still imagine the static building up. Incidentally, it is an industry standard not to mix shavings and dust.
You system looks good Paul, don't worry about having bits left over, that always happens to me when I fix the car and it is still running!
