Glad you made it back, Todd. Now that Rick459 has made one and we’ve been able to discuss it, I think I’ll be able to turn one for myself on my antique Lompoc/Sheldon lathe. Fortunately it’s equipped with collets, so making one or more out of drill rod should be a fairly straightforward task.
I’d still love to see somebody copy this tool in brass with mild steel internal parts. Of course then the shell holders would become the limiting factor.

PS Moderators, if you would like us to continue this in the “Hand Tools” forum, please move the main body of this for us so we don’t lose it all... it has become a pretty useful discussion.
