First order of business would be to make sure that the piano doesn't move off pitch very far between tunings. Stability on pianos that have rendering problems and extreme bearing angles or string to felt friction issues (like the Kawai) requires that the piano stays as close to pitch as possible. Churches are notorious for poor control of conditions that contribute to instability. A full DC system with bottom cover and upper string cover is called for and if that's not the issue then you need to address the problems that are creating poor rendering (at their expense) such as restringing, dressing capo bars, changing agraffes, modifiying counterbearing angles or areas if necessary. If every tuning requires you to make two trips at the price of one then I wonder how much value this customer really has under the present arrangement. If the problem isn't the quality and stability of your tuning (and I'm assuming it's not), don't make their problem yours. Help them solve their problem with some well thought out analysis and proposals and don't apologize that they will have to pay for it-of course, it may be a bit late for that as you've set a poor precedent. As for the Kawai, I would try and make the same analysis. Are you having to correct the pitch much at each tuning? If so, then the rendering problems will be compounded by the extreme pitch changes which in and of itself will tend to contribute to poor stability (see Nossaman's recent posts on this subject). Otherwise, poor rendering is often a function of excess friction due to wear and tear. Sometimes pounding too hard can make it worse by driving the pitch sharp only to have it settle back later when the segments equalize. Also, lubricate the string/bearing contact points points with Protek before you start tuning-sometimes that helps.

I have a sister pair of M&H BBs in a church. These pianos absolutely defy rendering with certainty. Once I accepted this reality, I initiated making two courtesy visits: The first, one week after the tuning, the second two weeks after the tuning. The first courtesy visit I invariably find numerous unions significantly out and make the necessary corrections. The second week I find fewer unisons out and correct those. This is the only way I am able to be satisfied that the customer has a piano that is actually in tune. Fortunately for me though, the client is close enough that these courtesy visits far outweigh having to be concerned with charging additional fees. However, I see no reason on this particular piano you mention that you couldn't incorporate an additional charge for that type of service. This would eliminate call backs per se, and you would be professionally accepting this as one beast that can't be dealt with in one visit. If the customer is not amenable to some additional charges for what appears to be a very justifiable circumstance, then you will have to decide if you want to remain uncomfortable for the rest of your service days with this customer and this piano. It seems an easy call to me. Some things in life require greater effort and cost to arrive at desired results.

Getting the strings to render through the bearing points so that it is stable enough that I even feel comfortable leaving requires far more pounding than I think any piano should endure. -- Geoff -------------- next part -------------- An HTML attachment was scrubbed...
