I put together a video of the process here:

I also uploaded my slic3r config that I'm using right now. Feedback on how to improve it is welcome!

The remix worked great. I also found that in a "pinch", the stainless steel "cap nuts" at Lowes (3 in the blister pack) seem to be made the same way as the "good" brass nozzles but are a little harder to shape as you say. I ended up using the drill to spin it against a running bench grinding wheel and that seemed to shape it really nice. A quick sandpaper (fine grit emery cloth) in the jig polished it up really nice.Now I just need some .2mm and .3mm drill bits (my small bits only go down to #70 and I need #80 or smaller)
You basically had my idea already captured by your drill advancer jig. With the tweak in thing #296482 you can use THAT one as BOTH jigs (and will be quicker and less material intensive). It is linked under the "remixes" here: http://www.thingiverse.com/thi...
However, my thinking is that the tooling could be a LOT simpler.
For example you could do the "lathe" part with just the one end block and a shorter latch bolt. Then that end could also act as the "advancer" for the drill phase. Basically have the slot for the thumb wheel on it behind the bearing section lathe and only thread it on when you are going to drill. So I am suggesting:
1. shorten the lathe to have only one bearing section.
2. combine in the advancer capability of the other tool.
3. When using it as the lathe, leave out the advancer wheel
4. When drilling add in the wheel.
I may try to work something up out of your two pieces. The "chuck adapter" for the tiny bits seems ideal as you designed it.
Thanks for this!!
