For just showing the basic steps and tools needed, this one's pretty good Petey. 


I will however recommend that you get a different type of mandrel.  The generic ones like that one flex to much when you put force on them with the tailstock center.  The one pottz showed above from Woodpeckers looks really nice.  I currently use this one.  It's my favorite of all the ones I've tried but the downside is that on pens that have more than one turned piece, you can't align them and turn them at the same time.  I also have one like this that works better than having the tailstock center supporting the center of the mandrel.  But there was too much clearance between the mandrel shaft and the bore in the live center to suit me.  It's a good system but if I were going this way, I'd look towards the WP one like pottz has.  I'm sure it's made with the precision it needs to have.  Personally I like the first "between centers" one I linked because there is no collet and it keeps everything close to the spindle with no flex.  But I have to admit interest in the Woodpeckers one because it really is nice to be able to turn multiple pieces that some kits require at the same time.

And regarding finish, there are 1001 different methods out there.  That's something to research on it's own.  I like super glue and BLO for most pens and I know pottz likes spray lacquer.

The basics are pretty cut and dry and a good place to start.  But like anything, there are a ton of little process tweaks and tools to buy that you'll figure out along the way!
