Turn an extra long blank round to 3/4" diameter. Insert in collet chuck, finish turning to diameter you want the pen to be, drill to depth needed and glue in brass tube. At this point you can part off the extra length that is in the collet. No special mandrel needed.

If you don't want to make a mandrel how about the closed end mandrel from Penn State?

I had another thought about how to do a closed end part without a specific mandrel. I haven't tried it on a pen yet, but it was successful on making a closed end keyring out of a cutoff. I glued the tube in, but left an inch protruding. I then gripped the tube in a collet chuck and turned the piece. Then I only had to part off the brass tube and it was done.

I just use the transfer punch set. If I don't have one of the correct size I just take the next size larger and either turn it down or sand it down to the correct size and make a pin mandrel. Work on the end opposite the point so it's still usable as a transfer punch. Takes a while but cheaper than buying a mandrel for each tube size.

Geoff, that's not a half bad idea. I'd be a little concerned with the strength of the brass tube, but it certainly sounds doable with a bit of finesse, or perhaps another bit of wood, drilled to accept the brass tube, and turned down to add strength.

I really like the idea from the link posted about using a regular mandrel, a single bushing and some carefully placed holes too. Seeing as it doesn't require any new tooling whatsoever, I think I'll give that a go first. Now, which of my on-hand kits do I risk?

This is a lovely thread with some great ideas.

I tried it out today on a crochet hook handle, with a minor modification and it worked great. I held the blank as I described long enough to turn a tenon on the other end, then I held that end I the collet chuck for 90% of the work. When the bulk of it was done and finished, I flipped it around again and put the protruding tube in the collet to part off and finish the end.

Simple answers are almost always the best. This sounds like another good method. And you can turn the tenon to whatever diameter collet you're looking to use.

Yes, simple is good. As long as you have a piece of tube on hand that is the correct dims and longer than needed it should work well.
