Halfcaff just posted a beautiful closed end pen, describing his technique. I plan to use this mandrel technique very soon for my first a closed end pen, but am concerned that after drilling for the mandrel, the second bore for the tube may not be EXACTLY concentric. So my thought was to drill for the tube first, then use a fabricated insert to help guide the bit for drilling the area for the mandrel threads. Having not done any of this before, I would welcome comments on this modified approach to the same end...closed, that is:biggrin:
