I did just that. I hired Darrell Fandrich to build it. He started with a 5'10" case and soundboard built in Guangzhou, China but discarded the soundboard. We chose a scale design by Lothar Schell and a Holy Grail stringing scale by Fandrich with strings custom wound for the scale by Mapes in Kentucky. The stringing scale included special Mapes aluminum strings that cover the first six notes above the point where the overstring section begins—these are designed to better blend the the overstring transition which can otherwise be notchy. A custom soundboard was crafted in Boston from hand-picked straight-grain Siberian spruce and milled to a diaphragmatic shape that mimics Steinway soundboards where the center is about half an inch thick but, to enhance liveness and sustain power, tapers down to about 1/4 inch at the edges where it meets the case. A custom Renner action was added and outfitted with Abel Royal Blue grand hammers. Key weighting and fine voicing conducted in stages over the course of several months finished it off. That was in 1998-99 and it is still the best keyboard I have ever used.
