Ok I know AS has them but I remember or I think I do there was someone that used to make and sale then here. Does anyone remember who and if so does he still sale them?
Fangar use to make and sell these.
He has not logged on since 01-22-2009, and this thread is LONG CLOSED,
but you can see them here: http://www.penturners.org/forum/showthread.php?t=20338
This may be who you were thinking of?
You don't need a special mandrel for making closed end pens. Check the two articles on closed end pens at http://www.RedRiverPens.com/articles , #13 and #14. Several methods for holding the pen blank are shown. One uses a standard mandrel and a bushing and I use that "alternative" method to turn closed end pens.
Do a good turn daily!
