Yamaha hammer spring cord replacement, was Re: U1 hammer butt problem

Terry,

Tom Cole(and others) say they can replace the cords in 2 or 2 1/2 hours.  Tom 
gave at a technical at a chapter meeting last year where he gave a slide show 
and step-by-step instructions.

I've never done it before, but I have a cord replacement job pending.  I'm 
figuring on 4 hours as a first timer, counting learning curve.  Fortunately, the 
piano belongs to a store I contract for, so it's an ideal guinea pig 
situation.

If the pinning is still good, most people seem to think it's faster to do the 
cords than to replace the flanges.
