I needed an inexpensive 60 degree morse taper 2 to hold the end of the grip stock and also for the scales. I used a Whiteside nib mandrel along with a hollow center for the nib to slide through so it rests against the pen blank or spacer rings. When I tightened the tailstock just enough to hold the spring blank, it put so much pressure on the bearings that they clicked slightly as the machine turned - these aren't torsion bar bearings, after all, so lateral pressure causes external wear. I switched back to the 60 degree live center to hold the end of the handle in place. Lots of explanations, but what the heck. So the Revain box was a joke - it was in the box but rattled inside like a 1lb brick - there wasn't enough bubble wrap to store it in the shipping container. The residence center was wrapped in a plastic bag, had storage oil around it, and was in a plastic storage "container". It came brand new with no rust spots or defects. It fit perfectly and worked accurately on my delta lathe. No weird main chuck alignment issues. The design of the center was a bit unusual and perhaps worth mentioning. Other hubs I've seen have open bearings where you can see a plastic cap on the outside that should seal the bearing. This center has one end machined from a single piece of metal that wraps around the bearing from the outside, limiting the amount of dust/dirt that can get into the bearings. The actual point is narrow, which also allows you to get a little closer to your project. Interesting design. And the last thing - it's not exactly like the picture :)
