Closed end mandrel for slim

[Chasper]

I'm looking for a closed end mandrel to hold a slim tube. I know there are all sorts of ways to make them and even more options to turn a closed end on a regular mandrel. That is not what I'm looking for. I'm hoping to find a closed end mandrel that I can slip a slim tube over, tighten a couple nuts, and use over and over. Can someone direct me to a source please.

Arizona Silhouette has one. I have it - I havn't used it much lately, but its exactly as you described.

Back before I'd heard of "closed-end" pens, or the custom mandrels, I accomplished the same thing with a regular adjustable mandrel. I wrapped a bit of paper towel around the threads on the end - just enough for a friction fit. Then I turned the barrel against a live center.
