Small 2hp cyclone for dust. 1 hp fume exhaust should do. ------------------------------ Parker Leigh RPT Winchester VA (540) 722-3865 ------------------------------
Hi David, Those are great questions! We do a lot of action rebuilding in our shop, so a few saws and sanders are the main source of dust, and chemical/glue fumes as you mentioned from gluing hammers on WNG shanks, doing minor finish repairs, and ...
One of the most important reasons for three coils is that other technicians will be appraising your work. If they are expecting three tight coils with beckets/elbows at 90° then you need to have three tight coils and 90°. If they see sloppy work then ...

Why three coils? Simple...because it's always been done that way! When I was at Tuners Supply, forty-five years ago, that was the standard answer to most questions. ------------------------------ Gerry Johnston Haverhill, MA gj@gjpianotuner.com www.gjpianotuner.com ...
Another point is that coils should be tight such that no holes are showing and all beckets tightly crimped. I was taught this while a Belleyman at Sohmer. ------------------------------ Parker Leigh RPT Winchester VA (540) 722-3865 --------------- ...

Steve, Yes, I believe that is the rationale (more consistent pin depth in general) when I've seen it. I am also thinking though, that since the exit point of the wire from the pin is the same (i.e., same height above the plate), the actual number ...
Wim - Take a nice walk on the beach tomorrow and think this one over. If your 'flag-polling' is being caused by insufficient pin-in-block, it's not really "flag-polling". If the coil was inverted, and the active wire length extended from the top ...
It seems to me that I have seen some factory jobs in which smaller wire sizes had more windings than the bigger ones. I'm not sure, maybe some Yamaha models in which the capo section had 4 and agraffe section had 3. There's some sense to that in that ...
4 coils is too many. Not just for looks, but it prevents the pin from going down far enough in the block to keep it from flag poling during tuning. On single bass strings I've done only two coils, for the same reason. ------------------------------ ...
4 coils on plain wire probably max, 3 coils for low bass. ------------------------------ Parker Leigh RPT Winchester VA (540) 722-3865 ------------------------------
Curious... Does anyone routinely (or for some specific reason) put more than three coils on pins in their stringing? I've seen it occasionally. I think I recall seeing as many as 5 coils on some of Peter Mohr's work when he was still doing rebuilds ...
Hi Jovanni, First, welcome to the PTG! And congratulations on making the choice to start your journey. Several thoughts on your post that I feel are relevant: I don't believe the piano industry is shrinking at nearly the rate that the raw numbers ...
Hi Jovanni: Welcome to the Piano Technicians Guild forum. You are correct in your assessment of current conditions. In my opinion, the influx of imported pianos has hurt the rebuilding business, and that has reduced the opportunities for new technicians ...
Hello, I am a 23 year based around the Chicagoland area and was planning to become a public school music teacher and a freelance musician but I really only have a passion for music and not teaching. I was interested in becoming a piano technician ...
I need a 6' 2" grand moved from Carbondale, CO to Springfield, MA. Pickup and delivery is flexible. Piano needs a total rebuild, so does not need a temperature or humidity control move. I know about Modern, Walter, and Keyboard Carraige, but I was wondering ...
Cheapest way to go, at least in the short run, is "thoughts and prayers". Otherwise, it would help to be more specific, as your 'short' question accommodates much of existence as we know it. Are you asking about practice rooms for Dampchasers/humidifiers ...
Hello Wim, RH changes may be de tuning the piano. In Florida, Pianos at Universities have gone out of tune more than normal, due to the unusually cold weather in January and February. RH at my Orlando University dropped from 62% in December (when I ...
Hi CAUT members! I am trying to do some research about what other schools are doing for 1) Dust Collection/ventilation in their shop 2) Humidity control. If you have a woodshop/workshop for your university (or even at home), what is your method for ...
A follow-up post after the service call and work. Before starting I had checked downweight at various points and it was all over the map. While I'm sure that all of the steps taken were useful and necessary, especially changing the damper lift timing ...
This one was a headache. And it most certainly isn't a Bosendorfer but the most bizarre thing is that it had a Kelly Plates and Schwander Actions. It produced a great deal of sound, past that….It was loud, I dare say, not pleasant. 😬 definitely ...
. If a plates only good contact is in the middle, the block and or plate may pivot back and forth like a teeter totter.
I share your pain because there are always going to be difficult and demanding clients that insist it is the technician or the piano or both and never them. You can do your best work but heavy hitters are going to wail away knocking out tunings, break ...

John, Yes, rock hard hammers is exactly as you say...no volume with "normal" hammers. The first time I encountered this hammer replacement was first on the list (cuz I had yet to learn the other details of the symptom set). I was totally dismayed ...
Actually, I'm not 100% sure the above data is from a Yamaha C3 but that is what the file name indicates. Speaking lengths in mm would need to be compared. ------------------------------ Tremaine Parsons RPT Georgetown CA (530) 333-9299 ------------ ...
My take is that this is a problem for the professor in question to resolve together with the administration. I might inform my supervisor of what the professor is saying, as an FYI. Leave it to them to work it out. I would not initiate the hiring of someone ...
I think I would be inclined to follow what is stamped on the bridge. The below data came from North Bennet Street School and was represented as original but I am not sure that the plain wire sizes have not been tweaked. The DIAM numbers are in thousands ...
Wim: Sorry for this crummy situation. I have over 20 year full time institutional piano tech work; one thing I've learned is that 'where there are faculty there will be difficult faculty'. My gut reaction would be: do your best work; ignore the faculty ...
I have sympathy for the difficult situation you have. Before announcing to management that you must decline tuning the pianos for this professor, I'd recommend meeting and discussing the problem with the management, ie department head or whoever you directly ...
Order replacements from Yamaha. Usually the Japanese ones are hard, and they come in different heights (9 - 11mm, maybe 1/2mm steps) . You might also consider checking and shimming the pinblock at the flange if it needs it, that might make the ...
Floyd, there was this discussion a few months back and Don Mannino reminded us that Japanese manufacturers use hardwood pin bushings and most American bushings are soft wood. Another thing to consider. Don't know about the size. ------------------------------ ...

Wim - Alan's scenario seems straightforward enough, which is why it's so unlikely to work. This tuning arrangement is ripe for abuse. Here are some questions: how many piano faculty? percentage of faculty in jazz department (if there is a separate ...
Hey Wim, Given your description of the scenario, if it were me, I would "humbly" suggest that she bring in someone that can "satisfy" her. If someone else can, I would take them to lunch and learn from them. And if someone else, a tech of her choosing ...
I am one of two technicians at a university. While there is no contract, by mutual understanding, we are the only one the school calls for all piano work. At the school there is one professor who is "difficult". It seems she is never satisfied with the ...
I'll be restringing a 1977 Yamaha C3 in the foreseeable future that has had the tuning pin field flooded with some kind of pin tightening solution. The paint in the pin field area has been compromised. I'll be wanting to replace the tuning pin bushings ...

Hi all. Who in SC is a knowledgeable harpsichord technician near Columbia, SC? I know so little and we have a double manual with issues. Thanks Paul
Hi Tom, For Yamaha pianos, it's worth setting aside the American Wire Gauge designations altogether, for two reasons. First of all, the wire they were manufactured with conforms to a metric sizing specification, and second, I understand most if not ...
dI have a school client who was gifted a relatively "new" Baldwin grand. It has a Baldwin Concertmaster player system in it. The control box uses CD's (it's that old), and the box sticks out on the left side of the keybed, causing a knee-knocker situation. ...
Hello, I'm working on rebuilding a Yamaha C3. I found a scaling discrepancy and I'm interested to hear if anyone else has encountered this on a Yamaha grand or other pianos. Here is the anomaly. For notes 29-32, which are the 3rd to 6th notes in the ...
I thought seriously about the V bar issue but the problem is widespread in the agraffe sections too. Tuning pin torque is not an issue. I believe I checked plate bolts at some point but it's worth checking again. I am a bit skeptical about humidity or ...
Mr. Stevenson, That appears to be a Roscoe stair climber. You might contact Roger White https://rogerwhitepianos.com/ in West Palm Beach. He's an expert in the history and operation of that device. ------------------------------ Karl Roeder Pompano ...
My first suspicion would actually be way too much (or significantly uneven) downbearing, though would agree about the V-bar as a factor as well. I would take a close look at the crown to see if it is evenly, or unevenly distributed across the board. ...
