Thread: Cam Timing

And why is it called the "Berger" hole? from Archerytalk.com talking about recurve bows -

"Berger was a brand name for a cushion plunger and that hole is actually called the cushion plunger hole but it seems that most everyone calls it the Berger button hole. It's sort of like calling an adjustable wrench a Cresent wrench though Cresent was the brand name, not the type of wrench."

and the "Cushion Plunger" was at the centre of the bow and the arrow... or shoulda been.
