Hi Guys,
With all this jocularity about left and right, for those who don't know there is an up and down side to the drift. If you look carefully at the drift taper, one side is curved and the other is flat. The slot where you put the drift has curved ends, guess which way round the drift goes?
If it comes across that someone is a know-it-all, apologies, but if the above helps someone that is all that matters to me.
