Thanks everyone. I didn't think about WD-40 or Kerosene for cleaning the grease off. I have plenty WD-40 but no kerosene right now (I wouldn't use gas to clean it off though).
I surely wasn't aware I could use WD-40 as cutting oil for Aluminum. That is cool!
I'll buy one of the cheap cutting fluids mentioned for cutting steel too.
As far as synthetic motor oils go for lathe way oil, does it matter what weight I use? I have a left over quart of 5w30 Synthetic Oil that isn't being used.
As far as plastic pipe to practice on, I have been looking for some dlerin or similar to use. There is a new eBay seller that combines shipping very well and he just got delrin in (is that good to practice on?).
He specializes in small orders. I ordered several 12" long pieces of 6061 round Aluminum stock from him (3/8", 1/2", 5/8", 3/4", 7/8", 1" and 1-1/8" diameters) and he shipped them all for the single item shipping price Flat Rate Priority Mail from CA for only $4.95 (the stock was cheap too), (the next shipping price for larger orders is around $10.95 I think for next size package). Some places dont combine shipping like that on small orders.
Hope I am allowed to mention eBay sellers on here, here is his link if anyone needs to order some small pieces of stock.
Just ask for what his combined cost will be for your order so you know what he can fit in what size package. I'm open to any other places anyone knows about too though. Later on I will stock long lengths like I do steel plate, box tubing etc.
Thanks again everyone for the advice!
