Or....find a recently retired tech and ask to borrow.

David,
On a different subject. I have a friend, who is a fine piano player. He's recently moved to Dublin, because of the political B.S.here in the U.S. Long story. He has purchased a vintage 7'6" Bechstein and would like to do some regulating on it. I'm told the shipping container with most of his personal belongings is delayed and hasn't even left the states. All of his piano tools are in it.
Could you recommend a piano supplier in that area where I could purchase a few regulating tools to send to him.
Update on the Broadwood: I'm in the middle of tuning about 70 college pianos before the semester starts. Sometime soon I'm planning to return to the Broadwood for a more thorough inspection. I'll let you know what I find.
I appreciate it!
Gene Taets, R.P.T.

Brilliant and interesting
The reason is because these straight strung instruments have a different harmonic content from cross strung instruments and this is why I put forward a belief that it was the introduction of cross stringing that started the shift towards "modern" style equal temperament. The straight strung instruments - all that I've looked at - have a predominantly 3rd harmonic focus in the tenor/bass region whilst the cross strung instruments allow the 5th harmonic to emerge in the sound.
The straight strung instruments are tonally deficient by the measure against the cross strung instruments. It was that dazzling new sound that sold pianos in their industrial hundreds of thousands to buyers who were status-symbol hunters rather than musicians. The sound glistens and the key colour, which you've now discovered, is lost.
https://youtu.be/nWMPEpBN0FA is a direct comparison of experience between a mid-century concert Broadwood and a late century cross strung "modern" style instrument
Harpsichords in meantone are great, but I've yet to be persuaded about tuning the piano to 1/4 comma meantone. However, when you do, the Mozart piano sonatas come to life. Mozart goes into outrageous modulations - for a joke slipping on a banana skin for a couple of bars and then recovering as if nothing had happened - or for pathos. The 2nd sonata in F major, F minor, F major is masonic related to the 3rd degree.
Kirnberger III gives the nearest possible to the best of meantone on the piano without the nastiness, and brings out the colour of sound on the straight strung instruments - as well as bringing forward characteristics of the experience of the ancient piano onto the new instrument. There's a special way of tuning the new instrument to tame it which I will be happy to share with you confidentially.
are two examples experiencing the tonality and sustain on an 1802 Stodart, the closest a piano can sound to a harpsichord, and then bringing that experience forward onto the cross-strung modern genre of instrument, both tuned exactly the same with tamed Kirnberger III
I have come to find Kellner "well temperament" rather muddies the effects and so will tune it for unequal temperament novices but tune Kirnberger as the go-to concert tuning.
I did
https://youtu.be/O-cJUxwXrIQ as a quick tour of the tonal change for someone, very quickly at midnight before getting a 6am plane . . . somewhat marred by a demonstration of a pipe organ in meantone with one stop not fully drawn and marring the sound terribly. So please ignore that!
Best wishes

Hi David,
A few things...
1) I don't know if I'm responding to you directly or if this goes to the Group. Many of the posts above this one do not show up in my daily summary. I'm just learning.
2) I will give one obvious example, but many of the other equal temperament aural checks do not confirm proper intervals: a major third/major 10th test to verify a clean A3 - A4 octave does not even come close as with listening to the octave itself for cleanliness. The minor 3rd - major 6th test does not yield satisfying results either. I do not have the piano setup so I can't delve into it any deeper.
3) I tuned a harpsichord at the college where I teach piano technology to 1/4 meantone standard (from RCT library) and each person who came into the room went ugh, that sounds terrible. Some were music professors; however, after I demonstrated to them how the bearing was set, and the different character between several keys, their views changed. Our choral/orchestral director (professor) said after a while, "Oh, those pure thirds relax me."
4) I demonstrated to the whole class a bit later (and I did this theatrically, with one of my students playing the harpsichord) how Chopin's Prelude Op. 28, No. 4 in e minor spoke of an unrequited love until it resolved into a successful tryst. Then she played it on a well-tuned vertical. Yuck! After that, back to the harpsichord for cleansing the palate.
I tuned a Baldwin SF-10 after class that night and found equal temperament excruciatingly harsh.
Convert? Maybe.
Regards,
Peter

Gene and Peter
Please forgive me for being confused by different instruments on this thread. I haven't been able to see photos if any have been posted.
Underdampers would indicate an instrument possibly in the 1850s. Not later.
If the decal on the fallboard is paper in a wooden rectangle it is before mid 1850s. If it's squirly script it will be late 1850s to 1870s and if a typeface lettering, later.
If the wrestplank isn't iron with threaded pins, then it's 1850s and before.
As someone else says here, keeping original is vital in terms of hammers and other things, and tuning pins too.
Peter - what do you mean by Equal Temperament tests? Your observation might be quite interesting and important so if you could expand on this it would be potentially very helpful.
On the 1869 Cottage Grand we restrung with Roslau blue. The treble is weak with many false notes and this coincides with a lack of crown in the soundboard in that region. Would Paulello help with this? A historic instrument restoration friend says that he has met instruments of this date and type before and the old trick was to use wedges to force the soundboard up and he has a special system of miniature acro-props. The 1850 Hallé instrument is sounding similarly woody in the top octave and probably from the same issue.
We used Heller Bass for the wound strings. And yes, they are moderated by felt on the bridge. Keep it.
Best wishes
David P

I've tuned two of the three pianos for a customer who recently moved to my town. The third one is a 7'4" John Broadwood & Sons grand piano. It's in sad shape and the customer was interested in restoring it, or at least getting a price. The keyslip is hinged, and on the inside of it is stamped the number 22525. Pierce Atlas puts it circa 1885, although it looks older than that to me. It has oblong tuning pins, dampers under the strings, etc.
I've rebuilt hundreds of pianos, but not one quite like this. I was interested in speaking directly to someone who is familiar with these instruments for some advice.
Thanks in advance!
