Thank you Gary for the kind words. If you ever are in the Seattle area please try to find the time to visit my shop. I would very much enjoy showing you my pianos.

It is difficult to innovate in such a mature industry such as the piano. But the mystery of what contributes to making an instrument with a great capacity for musical expression is one that intrigues me. When I was young and just starting piano work, I kept looking for some old guy who knew all the elements. I felt sure there had to be someone who understood the physics and engineering. When events evolved that staying in university was no longer necessary to avoid going to Vietnam-I dropped out thinking that "I'll get this piano thing figured out and then I will go back to finish my chemistry degree."

I never found that "old guy" until recently-I looked in the mirror and I was OLD! But I still don't have all the questions answered-and maybe don't even know all the best questions to ask! And I still don't have a degree.
In a seemingly infinite universe-infinite human creativity is-seemingly possible

Yesterday a colleague and I were able to check out Ed's freshly remanufactured M&H BB (1970s vintage) which features his FTDS design. This instrument was purchased from Prossers in June of this year for a neighborhood high school performance venue. Prior to that it had received no reconditioning excepting hammer reshaping and periodic regulation. Given Ed's extensive handiwork,(new block, rescaled lower tenor and bass section(Mapes custom made strings with stainless steel wound tri-chords at the tenor/bass break), WNG shanks,Ronsen hammers, key rebalancing, reconfigured bridge thicknesses and other modifications best explained by Ed, I can't say to what extent the FTDS alone is responsible for its substantially improved clarity, power, and sustain in the last two octaves consistent with Ed's claims. I can say that in its unrestored state, from C5 up the treble displayed the problems Ed has enumerated as does the 1971 Mason A we're about to rebuild which has resisted conventional hammer mating/voicing and string leveling remedies. At the very least his FTDS which includes meticulous reshaping of the V-bar, height/alignment of agraffes and counterbearing angle adjustments has effectively eliminated any sizzles, snare drum/buzzes noises. In combination with optimizing strike point and his choice of Ronsen hammers, the tails of which he aggressively tapers to around 5 or 6 mm in the high treble (possible with WNG shanks) to lower mass, I suspect the FTDS contributes in large part to the greatly improved sustain, power, singing quality and color in the upper register. Over a range of dynamic levels the piano's tone was even, full-bodied and orchestral sounding without ever becoming strident even at fff. All in all a marvelous piano now. I will be visiting the music director at the H.S and may have more to report in a later post.
