Hi Eddy,

Many thanks for your reply.
Yes, I read about your routine I understand what you are doing. What you say is a help to me I will probably go for the water cooled one as due to the lesser noise. I will have to see if I can get a good deal on one I may check with you guys before I go off and make a purchase. I expect to get a good finish running at 16000 rpm so it sounds like it may not be much of a demand on a spindle.
Many thanks
