Just found this one, so sorry for the bump, but since I knew the answer...
Bill Grumbine turned the vast majority of the catalog pens for PSI when they first got into it. He tells the story better, but in a nutshell, the owner sent him every kit they currently sold along with a bunch of blanks... several weeks later he returned a package with the pens.
When I questioned the ability to make much profit due to the slow speed of turning a single pen (this is before I was a penturner myself, so I had no basis for comparison), he told me they could be done in under 5 minutes. I had my skeptical look on, so he decided to prove it. Other than using a blank that already had the tubes glued in, I watched him turn a slimline in roughly 4:30, from pulling the blank out of the drawer to handing me n assembled pen. Of course, there was no CA, wax or other polish on it, but he accomplished exactly what he said he would.
Bill is one heck of a turner, but pens aren't his real area of interest, so don't expect to see too many more come out of his shop. If you get an opportunity, I suggest to everyone to take a full-day class with him. His prices are very reasonable, he'll school you on whatever subject you wish to learn, and you get a nice home-cooked meal with his family. He's got a bit of a sharp wit about him and a good sense of humor, so if you're anywhere close to the same, it makes for a very enjoyable experience.
