I just made this one out of Osage...
While Oak may not have as tight of grain as some other hardwoods, I believe that in short time and use, the grain would fill in with leather dust, stain, Tag, or anything else that comes in contact with it, and in time be just as slick.
Also, finish it off with some real fine grit sandpaper, like 300-400, while it's turning.
With you using it at 1725rpm or so, you'll get good results.
