Is this Soundboard shot?

  • 1.  Is this Soundboard shot?

    Posted 11-21-2019 19:06
    Hello community, 
    So, I noticed a couple cracks in the soundboard of the Anderson 125 year old piano. At this point, I am no longer sure if it's worth it to continue to restore it or not. Especially if I have to replace the soundboard. I have attached some photos of the soundboard. In some places, it appears that it's delaminating, even though it's a solid piece and not plywood. In other places, it looks like there are hairline cracks developing with the grain but the cracks are through cracks and not just on top of the board. I know the bridge caps are shot and need to at least be planed down to good wood and another piece of maple glued on top of them. What do you guys think?

    If its a 125 years old then yes it should be replaced.

    Is it worth it?  It's up to the client, What do they say?

    I'm putting in a board in this little guy (4'10"). The customer inherited it and is having it refinished, new board, new pinblock, new action parts, new everything. Pretty much just using the shell to build a new piano.  It's a Behning, and this one had a couple of unusual features as part of the soundboard design. First time I ever saw the long bridge attached to the rim. Hmmm. As seen in the picture. I just did a Chladni test to find its fundamental frequency so there is still sand on the board.  I also saw that the sand stayed too far away from the spine side indicating too much stiffness in that sector.

    Chris, so this is not for a client. I was given this piano for free by a lady trying to get rid of it.. So I don't really have any emotional connection to it in all honesty. Which brings me to my question as to whether it's worth restoring or not. From my research on the brand, it's supposedly an average piano. Which is what's throwing me on whether or not it should be restored given the fact that I know the pinboard is shot completely, there's a couple broken hammers, the bridge caps are pretty bad too. And now the soundboard. you know?

    It's really hard to say from the pictures.  The cracks don't look that severe but even a few cracks aren't necessarily a reason to replace the board.  Did you measure crown both before destringing and after?  How are the rim and rib glue joints?  What did it sound like before you took it down?  To keep the board you need to have some crown (Gravagne wrote some articles some time ago about assessing boards--search the journal archives).  It's very likely that a 125 year old board should be replaced but it's not a forgone conclusion.  If the board still has crown and the glue joints are solid then I'd say you could choose to keep it.  It does appear that the bridge many need recapping.  In replacing a board, that accounts for much of the work, so the question is do you want to do all that work over an old board?  Aside from the material costs (which really aren't that much in the whole scheme of things if you are rebuiding the piano completely) changing the board isn't that much more work.  You can also do an epoxy treatment (Fandrich's article on that was already referenced).  

    The piano is of modest quality and value and the work you would do likely exceeds the value of the piano under the best circumstances.  I don't know if this is a customer job, a spec job or a learning job.  If it's a customer job then my advice to folks generally is if the piano is an heirloom instrument and you intend to pass it on to generations then do the work as thoroughly as possible even if the cost exceeds the value.  Otherwise dump it and buy something else.  If it's a spec job then you're losing money (in terms of cost of your labor) so I'd probably see if the old board can be used using the criteria I mentioned above.  If it's a learning job then replace the board.  At least you'll get some experience out of it.

    So, I got it without the  strings.. I wouldn't be able to measure the crown before. I haven't really measured the crown after yet either. This is a piano that was given to me for free.. I would LOVE the learning experience part of it, but I don't have the time, and it's been sitting like that for over a year now. I am planning on moving, and I don't know if it's even worth moving it with me given that it is in fact mediocre brand piano to begin with

    You can use it as a learning experience. I would have advised the original owner to send it to the landfill. They crush cars...

    Mention of epoxy repair . . . . In my view cyanoacrylate is potentially better as it's capable of soaking into the pores of the wood. Now that CA has withstood the test of time for many might it be better than epoxy for some purposes and potentially in such a case here?

    Susan and Sam-
    I've marked Susan's messages for moderator opinion because the material shared is a member benefit and Mr. Joud and Mr. Pinnegar are not PTG members. The non-member price for the 30 year Journal disc is quite high, as members have paid significantly for this material through their dues.

    It's a particular and appreciated privilege to be permitted to be part of this professional forum and I thank all for the graciousness with which that privilege has been extended to me. 

    For my part
    a. I'm quite willing to pay, on the one hand, and 
    b. my position is more that of a facilitator for whom discernment is important, rather than someone making a living out of technical knowledge.

    At Hammerwood, a historic house open to the public, I've been promoting concerts and music for many years, and it was through that path that I came into the tuning of the instruments. The growth of a collection of historic instruments has been part of a voyage of discovery that's led me further and further into tuning, and through harpsichords and historic pianos, particularly more recently from the former Finchcocks Collection  https://www.finchcocks.co.uk/collection.html  and the Colt Collection  https://en.wikipedia.org/wiki/Colt_Clavier_Collection 

    Together with Michael Gamble's mentorship, professional information here provides discernment with regard to current practice, approaches and solutions, and assists me in making better judgment in the good curatorship of an increasing number of instruments, some given to the house such as an 1830s Broadwood square recently.

    It's been these instruments that have assisted in honing tuning, understanding its harmonic structure with the result of the ability to bring the best of the past forward to the modern piano, and which I've shared to greater and lesser degrees privately and publicly among other PTG members, hopefully giving inspiration to others.

    I tune elsewhere because people ask me to because people want the tuning I'm doing and others aren't doing it, and am organising seminars specifically among tuners who want to bring forward similar concepts of tuning, the purpose of which is to encourage better sonic reward for musicians, better musicianship and thereby to encourage higher take up of commercial demand for the piano as an instrument to the betterment of professional interests.

    So information in this thread is never going to be used by me directly, as I have a multitude of different interests and responsibilities which will preclude me ever taking a piano apart for rebuilding with the  expertise shared and demonstrated by professionals who share in these threads. But it enables me to see best practice, and to recognise where that is, and if and where appropriate to recommend people to come to such experts as write here if and when any possible quick fixes aren't appropriate. Particularly in the information shared in this thread, it's an indication of the sort of problems that one can expect in an instrument, the reasons why, and the economic balance of addressing them.

    So from that point of view I hope that moderators and commercial members here will not consider my being party to information here as being of leakage of commercially important information.

    The PTG threads where information like that in this thread is discussed bring to light what appears to be superiority of technical know-how in the USA where piano building is still active, rather than in England and France where people formerly trained in piano manufacturing enterprises are few and far between. When I see instruments from workshops that have rebuilt instruments in England, there are few that I fall in love with, whereas the level of consciousness of good practise in the USA that we see here is much higher.

    Returning specifically to the subject matter of this thread, where a cr*p instrument is of marginal worth, it can still be potentially helpful in the inspiration of a young player even if not perfect. I had a grandfather's Chappell instrument which is of horrible design, with bass bridge much too close to the edge of the soundboard and a horrible change of tone between unwound and wound strings, and a pin-block which reacted to central heating horribly, the pins losing grip. The bass strings were dead and it really wasn't worth spending money on. I was close to sending it to the bonfire. But I treated the pins with CA, more than once, used it for the tuning seminar last May https://www.youtube.com/watch?v=k61eHv9piMc and then gave the piano to a visiting violinist https://www.youtube.com/watch?v=M7id1yyDpQ8 for her sons to learn on, and who have found it a great inspiration.

    Perhaps there may be other 2nd rate instruments which might tell a similar story for themselves, encouraging music and inspiring the young. There may be a place for instruments, mended perhaps rather than restored, with love, and saved from the bonfire.

    Perhaps the circumstances outlined above might give confidence to moderators and professional members that publication of what is felt even to be of commercial knowledge is actually of such a specialised nature requiring deep devotion and commitment to professional expertise, that it's going to be hardly of commercial worth to amateurs but of very significant inspiration for those on the fringes of the piano repair world to come to those professionals who are really in-the-know and of which we see exemplified here.

    Discussion of piano structure, the tension on soundboards and the like is matter of deep importance to the quality of an instrument and of which amateurs should have an awareness, but deep within the instrument way beyond the observation of someone such as myself who wields a tuning hammer from time to time.

    Best wishes

    David P

    David, the information is readily available for purchase at ptg.org. The compilation DVD of the Piano Technicians Journal is available for purchase, $50 for members and $295 for non-members. Journal subscription is also available however I don't believe it gives access to all past issues.

    Mr. Sutton,
    Just curious how you'd feel about my sharing the information found on the discs with a non-member colleague in my shop? Is the information itself embargoed or just the manner of sharing?  Having bought the album can I play the music for others in a not for profit setting or must I first determine that all the listeners are also owners of the album?  Does keeping the information behind a paywall make membership more appealing or does it foster ill will from the excluded thus reducing their inclination to join?  I don't claim to know the answers to the above but hope you've considered them and asked the moderators to do the same.

    My understanding of copyright law is this: If you purchased the information, you can use it for your own personal benefit. I think you can also loan the information to others (think library), as long as you are not reproducing it. 


    However, reproducing the material, whether you print or electronically - which is what Susan did by copying and pasting those articles - is prohibited by copyright law, even if it's not for profit. One must get the copyright holder's permission first. In this case there are two copyright holders, the author and the publisher, PTG. I think both would have to give permission, unless one or both have relinquished or lost their hold on the copyright. 


    Again, this is just my understanding, after studying this issue briefly some time ago. It is not to be construed as legal advice. If you need legal advice, please contact a lawyer. Or you can send me a multi-thousand dollar check, and I'll research the issue some more.  😉

    Mr. Roeder,
    Benjamin Sanchez has parsed the legal side better than I could have.
    My concern was that the Journal 30 year DVD is sold to the public at a much higher price than to members, the intention being to make it more economical to join than to purchase the disc.
    We have the situation that people who are not PTG members, and who are, I stress, welcome to participate in these conversations, at times go a rather long way in seeking free advice from our members, and some of our members are eager to offer that advice. As long as this is the freely given personal advice, that is fine, and often to the benefit of all of us.
    My concern was the situation where a member is giving out extensive, copyrighted PTG material. 
    I don't claim to be the authority about this, but I think it needs to be examined by appropriate people in PTG, so I marked the messages for moderation and wrote a message explaining why, now in even more detail!

    Hello, All,

    Hmmm...once again, things on this list spiral towards unknowing based on
    lack of actual knowledge and/or expertise.

    _IF_ the question has boiled down to whether or not a given person has
    somehow violated some section of a legal code that broadly covers the
    majority of the people subscribed to the list, then, the reasonable
    course would be do to some actual research. To my eye, that has not
    happened. Rather, we have opinion based on hearsay, backed by no
    substantive understanding.

    To put things in a hopefully more informed perspective, one might
    quickly check Google to see what might come up. Just now, using the
    following search terms:

    permissible use of copyrighted material

    Among other related items, this search returns links to the USCode
    section relating to copyright:

    17 U.S.C. ?? 107

    or

    U.S. Code Title 17 Copyrights ?? 107

    It took less than two minutes to search and parse to find the following
    link:

    https://www.copyright.gov/title17/92chap1.html#107


    Section 107 is entitled: "Limitations on exclusive rights: Fair use";
    and is included here:

    "Notwithstanding the provisions of sections 106 and 106A, the fair use
    of a copyrighted work, including such use by reproduction in copies or
    phonorecords or by any other means specified by that section, for
    purposes such as criticism, comment, news reporting, teaching (including
    multiple copies for classroom use), scholarship, or research, is not an
    infringement of copyright. In determining whether the use made of a work
    in any particular case is a fair use the factors to be considered shall
    include???

    (1) the purpose and character of the use, including whether such use is
    of a commercial nature or is for nonprofit educational purposes;

    (2) the nature of the copyrighted work;

    (3) the amount and substantiality of the portion used in relation to the
    copyrighted work as a whole; and

    (4) the effect of the use upon the potential market for or value of the
    copyrighted work.

    The fact that a work is unpublished shall not itself bar a finding of
    fair use if such finding is made upon consideration of all the above
    factors."


    Looking at the above; and considering that the guild prides itself on
    supporting the education of people about piano technology, its hard to
    see where a substantive legal theory (one that might actually find
    standing in court) could be developed in a situation in which the
    promulgation of material was specifically for the purpose of educating
    another.

    Over a fairly long period of time now, a number of list subscribers to
    this (and previous) lists have freely shared a wide variety of
    previously published material. Sometimes, this has included material
    previously published in either print (usually via the journal), or, in
    some other media. In those cases, I generally agree with Ed's assessment.

    In this case, as the specific use appears to be for the purpose of
    sharing specific information (that is: "teaching"), then, the use might
    well fall under the portion of the opening paragraph of ??107:

    "teaching (including multiple copies for classroom use)"

    While a generalized EM list is not a traditional classroom, particularly
    as set up under the Higher Logic system, it would most likely qualify as
    "distance learning"; and would likely be covered under "fair use".

    My initial concern is the assertion of copyright protection in a case in
    which the validity of the assertion is not in evidence. By that, I
    mean, in whom (thinking of businesses as persons...something we have to
    do since Citizens United; but that's another conversation) does the
    copyright for materials published in the journal actually vest? Does it
    vest in the guild, or, does it vest in the original author? Or, does it
    vest in both, based upon some contractural arrangement? That is, based
    on the number of technicians who have written books and pamphlets that
    appear to have been based on journal articles, what arrangements are
    made so that the reasonable interests of all parties are reasonably
    protected?

    My secondary concern is that, if this kind of thinking leads to a
    conception, or set of conceptions, in which the guild is effectively
    perceived to be the sole source for certain kinds of knowledge,
    training, vestiture ("licensing" in the sense of gaining some
    pre-defined level of membership), &c, then, it's a very slippery slope
    into areas of restriction of trade, which has a long history of not
    going very well for would-be restrictors.

    Ed, I am very glad to see that you have referred this to the moderators.
    With luck, they, in turn, will contact whoever acts as counsel for the
    guild; and that person will be able to supply more clarity. In the
    meantime, this is all speculation which doesn't seem to be doing anyone
    much good.

    Kind regards.

    Thank you, Horace. Certainly educational value was what caused me to quote the articles.

    Someone had tried and failed to locate Del's Journal articles and had asked for help.

    If I deserve blame in this, it's because I didn't check with Del beforehand, taking it for granted that he wouldn't mind, and would probably like  having the articles brought back to light.

    From my days of writing articles for the Journal, and dealing with many requests for permission to reprint in various publications from the rest of the English-speaking piano technician world, I know the official rules about permissions to reprint. The author of a Journal article is allowed to give permission to reprint, so long as the publication does not duplicate the Journal's format, which of course I didn't.

    Also, of course, no money has changed hands, and no one pays for access to this list.

    So it really comes down to whether Del objects to what I've done. If he does, I certainly owe him an apology.

    Horace, since you have a law degree and a lot of knowledge about all this, how long would Journal copyrights last? Before what date would Journal material have entered public domain? I have a lot of very old Journals!

    If as an outsider I might be excused in making a rather cheeky observation . . . . were the enquirer to make use of the very valuable knowledge shared, to do such work on an instrument which will never achieve a commercial value anywhere near that of the time and materials engaged must be one of the best examples of a labour of love and a not-for-profit endeavour. His encouragement may well be encouragement for more.

    Such otherwise scrap instruments are really valuable in the learning process, ones on which mistakes can be made and I was encouraging a friend today to find just such an instrument upon which to practice wielding a tuning hammer. 

    Best wishes

    Looking only at this statement, setting aside the copyright questions, I just want to point out that non-PTG list members also bring their own knowledge and experience, which they share freely on the list. I, for one, greatly value their insights, especially since for some of them, their experiences in distant countries, sometimes over decades, differ from ours.

    Hi Abed, there's an enormous amount of time spent doing all that has to be done to this piano and when it all done, you still have a small "no name" grand.  A learning experience?  Well OK if you feel you'd like to do that.  There's many hats a piano rebuilder has to wear to get to the final product.  To wear all of them well is indeed an accomplishment.  Soundboard?  Yeah it's gone.  They burn well.  The rest of the piano burns quite nicely as well.  Need something to do?  Watch it burn and have a beer or two instead of investing hundreds of hours in this sad old heap.

    I was recently asked to assess a small grand for sale by owner.  What I found was the end result of a project like this one.  A 1920 something under 5 footer that had it all replaced except the pin block ........  or at least the #4 tuning pins told me so.  Yes including the soundboard and bridges.  The asking price was $1100. 

    I'd rather go fishing, kayaking, rock hounding, or just simply sit by the fire and watch the sun go across the sky [ or the moon make faces at me], walk an old RR line, chase girls, pull weeds, turn compost, clean and put away in the shop, watch YouTube, .......  All those things would give me more pleasure than trying to bring this old PSO back to ... uh .... what little life it had at one time.

    Just another perspective.

    The piano soundboard is not a boat. They have different objectives. With musical instruments the aim should be musical. Furniture would be made from a structural perspective, but the craft of making a musical instrument is about tone.  For example, music wire. If you see a nick in the wire, and are concerned about it breaking. As a fix, you could lower the tension to such a degree, that its breaking is no longer a concern. But, it's less or becomes non- musical.

    There seems to be a focus on stiffness, but what is missing is strain. As a thought experiment, you could get thick steel rods, and if you could somehow attach them to the bridge and capo bar, you could not deny that they are very stiff. But they would not be musical for piano tone. There were some builders of nice instruments of the past, that used strain in their soundboard systems. What they did to incorporate strain was to have an angled rim and  arched the board along the grain. The modern piano uses another system of strain in the form of compression against the grain. 

    In the picture I posted above, the compression soundboard is a hundred and twenty years old, and has no cracks. I can put a soundboard panel in the kiln, dry it out, then remove it and let it grow again. And guess what happens, it grows all the way back. From 1% to 12 % it will move about ½" or more. That's pretty elastic. For a crack to happen it has to come under tension across the grain. Knowing how elastic the material is, I'm seeing cracks as an installation problem and a "not taken care of properly" problem. For tension to occur across the grain, the board got drier in emc% than when it was installed.

    Regardless, as the article points out, the epoxy repair is a last resort.  So if it saves a piano here and there, then that's probably a good thing.
