How should I make this longish screw?

[mikey]

I used to knurl more often. I started out pretty good when I got my lathe, then got worse, then better..Haven't had to do much lately so screwed mine up a bit. I also should have knurled the whole thing then cleaned up where I didn't want knurl.. rather than trying to stop and start. Oh well, it's in the Won't do that again category for me, of course unless I forget what I did...
