Herr Condino's recent thread got me thinking...Why are hatpegs tapered at all? In fact, why are metal pegs tapered? I can think of no reason from a mechanical engineering standpoint. Wouldn't a straight peg work just as well? With cellos on up, you need a taper to hold the peg in position, but once you have a gear, the taper-induced hold becomes irrelevant. Is the taper on bass machines just a throwback to pre-machine days, or am I missing something?
