My kitchen fluorescent lamp which is 6 foot 100 watt unit wouldn't light tonite the starter flickered but no sign of any tube activity. It was very cold in the kitchen so I put the boiler on which warmed things up nicely I tried the tube again and although a bit sluggish it lit ( maybe my swearing at it helped) my question is do you think it's just because the tubes old and doesn't like the cold or is there something else going on?
and so I'm sure can you without me - the lowest speed at which you see a fixed no of multiples of the chuck key holes, and how many degrees they are apart at that many RPM, tells you the rotation angle and so the time between flashes and convert mins to secs for Hz.
or yo could use a photo cell and a 'scope. It all rather depends what sort of workshop you have -mine has a lot of electronics stuff in it, the lathe however is down the garden as a concession to domestic pressures.
