I have two basically unrelated questions, but I don't feel like posting two different threads to ask.
1. I've had mixed success with dropping Schmidt DSM 2006 mechanisms into pens. Theoretically they are compatible with any pen taking a Parker style ballpoint refill, but in practice there are sometimes odd compatibility issues that can be difficult to troubleshoot. Has anyone tried a DSM 2006 pencil mechanism with a Sierra style twist pen? Specifically I'm looking at these Prism ones, because I have this idea of making blue/red/green ones to use blue/red/green 0.7mm colored lead refills.
2. I am finding I get better results when using my 60° dead and live centers to turn pens, compared to my mandrel. With any pen using tubes larger than 7mm, that's easily done with the regular steel bushings. But with slimlines, the standard mandrel bushings don't work for TBC for obvious reasons. I have not had good luck just putting the tubes directly between centers, the brass is soft enough to flare out and even split sometimes, and if I use less pressure, I get a lot of slipping.
