hi all. i'm a novice machinist, and i will be working almost exclusively with aluminum on my sherline 5400 mill. i'm wondering what cutting fluids you'd recommend for aluminum. i have some A-9 that i've been using, which is a green colored oil. it works well, but it leaves a bit of a mess because it causes the chips to stick to everything and it gums up my cleaning brushes. is there an effective fluid i can use that won't leave such a mess? the soluble oil mixture we used in my machining class was easy to clean up, but i guess it's not terribly effective for alumimum?
thanks,
ben
