You win the OLD FART award of the day Chuck ! It IS a spring winder .
Some 25 years ago I took the old box in that I inherited from my uncle whom inherited from his dad into work and started going thru it . I was the youngster of the group , most of them being in their 60s . One of the tool makers grabbed this thing and wound a spring . WTH ? So I sit here today , not for the life of me , can I figure out how this thing works . I can't remember what I did an hour ago less 25 years ago !?
I guess I need the help of a ninety something tool and die maker ???
