Phantomcow2,
(is there a Phantomcow1?, I wonder)
Your a good machinist compaired to me! I did turn down a ball screw and it turned out good, I grinned like a teenager as I took it around to my love one showing what I had done. But Phantomcow2, I had to aneal the last last 2 inches in order to turn it down on my 9X20 Harbor Freight. I was using carbide tooling and had gone through 4 or 5 when I decided to set up a vertical water bath (using a garden hose and a piece of PVC, being from Mississippi, we tend to do a lot with stuff just laying around) and was able to heat just the last couple of inches, and then just let it air cool.
After that, it turned down nicely and threaded easily.
All that said, I planning to do some more ball screws, and it would be nice to turn it down without having to aneal the ends. So, if you can remember the details about the rpm, cutting depth, ect. that you used and how you prevented the screw from whipping. I would love to hear about it, because I still dont feel right about anealing the end (whether it will ever effect anything I don't know)
