My first lathe - don't laugh

Just came to mind that Stellite can be applied to steel by oxy acetylene welding or TIG and used as a wear surface; I have a quantity of Stellite cast rod for the purpose.
 
The Stellite tools that I have and have seen were blanks brazed onto high carbon steel shanks, like carbide, but the usable blank was much longer than a typical carbide tool, and could be sharpened back very much further.
It seems to me that it was invented and made by the Haynes Company, I think the same company as made the Haynes automobile.
We seem to be hijacking Jared's thread here, so I started a new thread here:

For aluminum or brass, which would be about 400 surface feet per minute (SFPM)
I'm a bit confused ,is the SFPM for Aluminum 250 or 400? thank s for helping a confused rookie.

Thanks Bob, For milling aluminum I calculate RPM using 250 x 4 divided by the diameter of the end mill, if I use 400 SFPM with a .500" end mill, the RPM will be beyond what my little mini mill can handle, that's why I asked thinking all this time I was way too slow . thanks for the clarification.

I use that same basic formula, Ken.
 
First chips! And, my first time operating a lathe :)

Check out my questionable lathe dog. :D Apparently I don't know how to center a hole in round stock on my drill press. Well, it worked, and I'm taking 0.020" cuts. I'm getting a real lathe dog and some new HSS blanks in the mail tomorrow. Then I need to find a chuck .. with the oddball 1/2"-24 spindle, that might be tricky.
 
Oh, and I forgot to mention, the tool bit has an engraving on it, "Rex AA" which I'm guessing stands for Ann Arbor, where the lathe was made, right? Or am I letting my imagination get away with me? :)

Probably a reach at your stage of machining, but this is an option:

Here are some adapters (and ideas):
