I’ve finished three new Funline pens. This will be a short post just showing my progress. 
Lessons Learned
- My mandrel saver isn’t as good at keeping the mandrel concentric as the nut is. So I’m using the nut and live center and getting good results again.
- Finish shaping with 150 grit isn’t working for me. It shapes fine but some of the scratches are so deep that I can run through all the grits and micro-mesh grits without removing all the scratches. I recommend finishing with tools and then going straight to 220 grit.
- Paint your tubes. These pens are so thin that the brass tube is clearly visible if the resin has any transparency at all.
