Default Homemade closed-end pen mandrel

I've been hoping to try my hand at a few closed end pens, but would like to convert a few existing pen kits, namely a few Raw's. I can't bring myself to order one of the mandrels, having tried some of the "expanding" types for making duck calls. They seem terrible. If you remove and reinstall a pen, they seem to always be a bit off.

For my calls, I machined my own pin mandrel, which works a real treat. However, that's a lot of work and supplies if I wanted a mandrel for each diameter of pen tube I may turn. I've seen some here use some homemade wood mandrels, and I was hoping for some advice on creating my own. Is it as simple as a veeery slight taper and constant use of calipers?

Any pointers would be greatly appreciated.
