How ironic...I just MADE about fifty of those on my lathe out of carriage
bolts, for a project we're doing at the outdoor railroad I work on every
Sunday (rebuilding an old SP depot baggage wagon). I had no idea they had a
name, nor that they were available!
Oh well, I needed the practice on my old lathe anyway, and I love the smell of
cutting fluid and hot steel...
Thanks to he or she who sent the link.
