Cigar transmission coupler

[Monty]

Looking for a source for cigar center couplers that the transmission screws onto. I use to be able to get them from several sources but currently I don't see them listed on Exotic Blanks, Woodturningz, Beartooth Woods, Arizona Silhouettes, or Woodnwhimzies.
Anyone know of a source for these couplers?

I destroyed a twist mechanism (just got a pen vise, so should not happen again) on a cigar twist from Berea disassembling it.
There are no parts on their website, so I called them today and they are sending me one free. Might try them.

Thanks for the suggestion but I need to purchase several of them. I use them in making 50 cal pens.
