I think the only difference between ETD and non-ETD users is ego. Much the same as someone saying, "I don't need a stinking machine, this sandpaper and block works just fine." Why use a pneumatic impact hammer to drive tuning pins, a hammer and punch does the job. Craftsmanship is not solely in the labor itself but the application of acquired skills and tools. <x-sigsep></x-sigsep> Regards, Jon Page, piano technician Harwich Port, Cape Cod, Mass. <a href="mailto:jonpage@comcast.net" eudora="autourl">mailto:jonpage@comcast.net </a>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</body> </html>
