Hello Richard,
Many thanks for the help and info here. My machine is down at the minute as the power to my workshop kept on tripping with just the angle grinder or the normal power tools, waiting for the sparke! One I have the mill back in the land of the living and some time to use it I will place an order for coolant. I will be sure to read what you have mentioned several times over as I learnt a lot.
Many thanks
Suesi
