Local machinist gave me a blue colored liquid (forgot what it was called) that worked great, till I ran out of it. Now I'm using Sulflo cutting oil, which is alright for aluminum cutting/threading, but the blue liquid worked much better.

Joe ' I use WD 40 , it works well . The reason I brake taps is the same reason I can't take good pics when holding the cam. . I found ATF works great on alum. when turning on the lathe , just gets a little pricey if you have to buy it just for that . Being a self taught machinist I've never herd of the different typs of lubes to use with what metals
