Hi Mogi - By the way if you make a mill and its uses coolant you will never do timber or porous stuff again. The lub and swarf goes everywhere and its a pain to try to keep clean,. So from that point on its a mill... If I cut aluminium on the router it takes me a long time to clean up the swarf and I find it 5m away from the machine over tables on the floor etc etc...
