I cant help wondering David whether the micro switch is best for the job as I/P to the turns counter? Its surprising how many RPM you can get up to once underway. Don't know what mine was but the 40,000 turns didn't take that long to wind and even at 100 rpm that would be 6.5 hours, so could at times have been more? Your switch could certainly be clattering round at a fair rate of knots. Actually a reasonable speed is OK as you see the trend in the build up of wire and can adjust to fill the hollows easily.
A better choice might have been a reed switch actuated by a magnet sunk into a disk of mdf say, possibly with a matching weight the other side.
Be interesting to see what happens.
