You are so out of luck!

It doesn't stop!

It is a deeeeep hole!
IF you DO want to avoid buying a lot of extras, then the alternative will be to read quite a bit and look at the kind of pen that you want to make.
Warning: While many people do make pens with mandrels, there are enough dissatisfied with low end and medium priced mandrels that they end up buying more high end mandrels - thereby spending more money. The problem with low end and medium priced is that the mandrels can be bent, warped and vibration introduced which makes for an imperfect pen. Barely noticeable but if you are a perfectionist, it is aggravating. If you think you may sell some pens, then you want to eliminate that and go to a quality mandrel system. TBC can eliminate these problems all together. But for two part pens, you can only turn once section at a time with TBC. For TBC, you will need a dead drive center to go with a live center. Regular bushings will work and there specialized bushings for TBC also.
Next, you have tools, do they require sharpening, or are they carbide inserts that can be replaced? If tools that need to be sharpened, do you know how to sharpen them and do you have the tools to sharpen them. The sharper, the better.
Get a good set of calipers (metal, not plastic) to measure your turnings. Do NOT trust the bushing for sizing. Bushings will decrease in size a tiny amount every time your sandpaper touches it while turning and the same with the tool.
Finish - CA is quick and makes a good protective finish, but some do not like it. Some like to finish with oils so that the natural beauty of the wood is felt and seen. Polyurethane , lacquers, and others take longer to CURE before handling. Each has a learning curve.
PRACTICE, Practice, Practice. Everyone want to make a pen. Make a couple or 3 or 4, or even a dozen. THEN get some pine or oak blanks, and get some extra tubes. Practice drilling blanks and practice glueing the tubes in. Practice getting used to the tools to the point that you can feel the difference in the handle with different kinds of wood or the speed of the lathe. Feeling Feed Back HELPS. Practice sanding. NOTE, With pens - realize this is not Flat Work - book shelves, tables etc. No need to start with 80 grit or 120 grit or even 180 grit. The grit from those numbers must be completely sanded OUT. The best of pens with excellent finishes are sanded to 600 or 800 before finish or oil is added. Too low a sanding number introduces deep scratches that have to be sanded all the way out or they WILL BE revealed in the end.

I am on a fact finding mission. Can you help? What do you wish you had known earlier in pen turning? or in different words: Knowing what you know now - IF you could go back and start over in pen turning - what would you skip, change or do differently? answers for instance: - I wish...

NO ONE set of tools is good for all kinds of pens. Spend some time - 30 minutes or an hour - looking through this thread and see what kind of pen you would like to make and then which tools are needed to make that pen.
Please post only your segmented pens in here and don't comment on anyones work just Like it then we can keep a record of works. Hope you all like the idea. Purple Heart and Black Ash Burl on a Jr. Gent 2 Fountain in Gold
