Tom, thank you very much mate, im not the best at these sort of calculations and you got it spot on. ive been cutting things for the last 5 days and its been ace!

Thank you again.

Next part of the build for this little monster is a coolant booth!

Btw, ive been cutting aluminium at 400 Feed and a D.O.C of 0.3 at 2800 RPM, seems to be solid so far, might try 0.5mm D.O.C tonight:whistling:
