“Hexbobbin” is the back of the bobbin. It is driven from the hex collar on the flyer. It snaps onto the flyer shaft. There is a very tiny key that aligns with the hex bobbin.
A US ¼ inch washer is in the top of the Hexbobbin.
The washer is a little under ¾ inch OD and .312 inch ID.
“Bobbin front” screws onto “bobbin shaft”.
The first time the bobbin is put onto the flyer shaft will empty the hole of print waste.
