I think the whole fit problem pretty obviously goes back to an historical absence of standards in our industry. Machine tools such as drill presses and lathes for a century have had spindles made with precise, dependable tapers, to precisely, dependably fit tooling which had to be changed fast and frequently. Anybody who has changed a chuck has probably appreciated the ubiquitous implementation of standard Morse and Jacob tapers. Unfortunately for us, it's too late to impose standards now, that bird has flown. I suppose tuning pin manufacturers _could_ decide to cooperate and define a standard taper for future tuning pins, but whose definition would prevail? But, hey, it would be nice ... -Mark Schecter Kent Swafford wrote: > > On Mar 25, 2009, at 9:06 PM, David Nereson wrote: > >> I would imagine the ends of tuning pins vary as much as the tips made >> to fit them. > > > Of course you are correct to point out that the shapes of tuning pins > vary pin to pin. > > As a practical matter, wouldn't it be easier to control the outside > shape of a tuning pin than to control the inside shape of a tuning tip? > I suspect tuning tips vary more than pins. > > > > Kent >
