i did not know this
but at least milling in al first i would get some experience since i never milled a water block in my life before, and i am going to mill it using a drill press and an xy table.
today i started my testing on milling. i started with a piece of steel (much harder than al to mill) and i hadn't a milling bit but normal drill bits. i found one which was split into 2 pieces, i got the piece which fixes up with the driller and used a mitresaw to flatten the bottom of the drill bit. i know that a milling bit is much better that i couldn't go and buy one today.
with this method and my drill press i managed to remove about 0.5mm from a piece of steel with no lubricant or coolant (just some water). i think i would at least manage to mill that block in al with a good mill and a good xy table. hope that i am not dreaming
