yeah sorry effective 2mm pitch, the screw is 3mm pitch (i hope, could be 1/8 imperial) but I plan to use a 3:2 reduction on the belt drive to gain a small increase in motor power and reduce loading on the screw.

cheers for the coolant advice hadnt thought about that. I have some ideas for the spindle but will wait till i can sort out the pics, will be easier to describe

P.S How do I up load pictures? Tried uploading to the media centre but it failed.:exclaim:
