Geoff, We saw Tuner tonight. Peter White is listed as the “Piano Consultant”. He and I were in Laroy Edwards last PPSS ( performance piano service seminar), a one week training given by Yamaha in Buena Park. Wayne Ferguson is listed as the “on set ...
I had the pleasure of seeing this movie last night. It's quite good. It's actually a very well played robbery/heist story with piano service holding it together. And "Tuner" is just the nickname of the main character. I really appreciated and enjoyed ...
The diaphragmatic design was largely a marketing gimmick like Accelerated action. Furthermore, tapering the treble area is the wrong place to taper. That is where you want maximum stiffness. In earlier decades I believe that Steinway Belleyman tapered ...
Oh I agree wholeheartedly: printing won't be able to replicate the properties of many of the materials the piano relies upon. The knuckles I created to fit these old thaler-style shanks were based on the silicone cores that WNG uses , perhaps one of ...
Greg I know 3D printing can do a lot of good things, but I don't think it's ready to duplicate the real felt used in hammers and real leather used on knuckles. But I'm open minded enough to consider it.
Have you considered laminated ribs? Less chance for hidden defects, more uniform physical characteristics, efficient use of spruce, easy to make any curve radius, etc., etc.!
Hi, Wim! I would be honored to give a presentation, I'll keep an eye out for a contact from Zack. I have seen Brigham Larson doing some amazing things lately with 3D Scanning and printing, he's really shedding a lot of light on the potential of 3DP ...
Hi Greg FWIW, Dr. Li Yeung, the head piano technician at Florida State University, is also into 3D printing for tools and parts. He will give a class about this at the Southeastern Regional Seminar, next April 8 - 10 in Knoxville, TN. In the ...
Greetings! A while back, there was a discussion about what software people were using to manage piano inventories. It happens that at the same time I was working on building my own solution. If anyone is interested, I've made this an open-source project. ...
"Gluing flat ribs is a Bad idea" Why? As I see it, compression crowning is the best way to go. If the goal is to maximize tone quality, and to take advantage of physics (i.e. the strength to weight ratio). Before i start, i am not saying that ...
Is that a picture of a go-bar deck? What materials is it made of? ------------------------------ Parker Leigh RPT Winchester VA (540) 722-3865 ------------------------------
Crown board will be machined concave, ribs machined to be convex, panel flat. Taper panel topside after ribs are glued on, scalloped and tapered. Yes original board is a good reference. Gluing flat ribs not a good idea, I prefer a rib crown board with ...
Parker wrote: " Bottom of rib planed or routed to match concave surface of crown board. " I'm trying to understand your process here. If you are shaping a rib to match the surface of a soundboard panel - why don't you just make the rib straight? ...
My preference is to study the original board and copy it as closely as possible and only make changes when there is a good reason to do so. Over the years i have come up with various tests to compare one board to another. I find the most important thing ...
Hello everyone, I'm Greg! I am still a humble student of this great craft, but I wish to give something back to the community that has been so helpful in my education. I have become more and more familiar with SCAD modeling over the years, and I have ...
Dear David! My father invented the measuring tool in 1985, and since then it has often been copied … but usually in rather odd ways. With ours, the starting point is the front edge of the hitch pin … this is the point that is also easiest to measure ...
Peter - Fair point, though we're stuck if we're ordering from Mapes or any other maker that hasn't yet marketed their own tape. I'd be curious to document the differences, if I can find my Heller and Arledge. More to the point would be from where the ...
Just remember that each maker has their own specific protocol for these things. Don't measure with a Hellerbass tape and order from Grandt, or vice versa. I learned that the hard way when I measured with an Arledge tape and ordered from Hellerbass (not ...

I was a belleyman at Sohmer and have been installing soundboards since 1983. I also trained under a veteran Steinway Belleyman, Valentine Toussaint. My pinblock training was with Wally Brooks. Worked at Bechstein (1979) and Bosendorfer (1980) and ...
Before you get too far into this, can you (both) give some idea of your prior experience doing this level of rebuilding? Thomas, I'm having some difficulty reconciling the appearance of your work (good) with the questions you're asking. ------------------------------ ...
Bottom of rib planed or routed to match concave surface of crown board. If using go-bar deck for gluiing ribs best to start with 4/4 spruce then plane or route sb side of rib to match crown board. After gluing ribs to board plane ribs to height and finish ...
Thank you Gregor! I will do that! And thank you David, that is useful information! Best, Luke Sent from my iPad
Your OTHER other option is www.jdgrandt.com - (905) 773-0087 This one appears to measure from bottom-rear of the hitchpin. Your OTHER, OTHER other way is to respond to Gregor Heller's post, just now. ------------------------------ David Skolnik [RPT] ...
Hey Luke, Gregor from Hellerbass here ... our special tape measure tools are not sold out ... just send us a short email with your address to service@hellerbass.com . You'll get one free of charge ... Kind regards Gregor ------------------------------ ...
Hi All, I'm trying to get my hands on a bass string measuring tape. It seems the Hellerbass version is sold out and Arledge is not currently doing business since they're selling the business. Are there any other suppliers selling these? My other ...

Hello fellow-techs. When rebuilding a piano and making pre-crowned ribs: which practice is more common or a better choice, making the height match across the rib, making its bottom side crowned to match the top glue surface - or, making the bottom of ...
Thanks, Floyd, that's helpful. In this particular case, I generally have 5-8 hours to work on the piano for the beginning-of-season prep, so having them turn on the heat in the morning generally wouldn't be a problem, as I can do the regulation and perhaps ...
A significant change in room temperature during the course of a tuning undoes your work as you proceed. If I walk into a venue and am told that the room was cold, but the heat was turned on 30 minutes ago, that is grounds for rescheduling the tuning. ...

Blaine Hebert's post rescued me from the mire I had submerged into trying to respond to Daniel D's excellent response. He brings us 'full-circle' with " How often do we insert a thin dowel through the strings to contact the back rail and check for ...
I like the term dangerous here as it seems that this is a difficult feature to measure and adjust and it could potentially be a source of a hard-to-find problem, like a knock, squeak or loss of power. Removing a front rail knock by sanding away all places ...
Well, if a piano gets mad, it can quickly turn on you and attack, and this becomes more likely the deeper in the action cavity you are working. Seriously, though, this is dangerous in the sense that it can create a difficult to diagnose, major problem. ...
Hi Richard, With a Steinway, the keyframe is fit to the dag blocks in manufacturing and is not generally considered serviceable as both surfaces are fixed and any adjustment will involve some amount of woodworking. While the front rail and balance rail ...
Why is contact at this point any more dangerous than the contact (and its friction) along the entire keyframe/keybed? or keyblock plate and end pins? And, for that matter, why dangerous ? It's just one more thing we have to learn to do carefully. ...

Daniel: How much attention should be given to bedding the back rail? And what is the most efficient way of doing that? Do the dags play any role? Richard West
The official name for the Steinway part is "keyframe hold down dag block". That's a mouthful so we simply call them "dags". (You'll never hear someone from Steinway call them dogs which implies a holdfast. An action with an una corda function should never ...

This is more in line with what I was thinking, though since it's summer, I thought I could be a little bit tighter. Have you had experience installing these? ------------------------------ Tom Dowell Hulbert Piano tom@hulbertpiano.com 262-221-0792 ...
Interesting. That would explain the rounded portion of the dag, to reduce contact area. I suppose that would need slight taper/wedge shape as well, to guide it home? Still, seems dangerous to have moving parts that actually touch like that, especially ...
I don't remember which 'old' Steinway tech explained this to me (and some other - less old) Steinway tech may disagree, but the positive 'capture' of the back rail serves to stabilize the action bedding to, among other things, prevent a 'knock' that ...
Peter, I thought the same about the dags, L screws under trap levers and the "shipping rail." That last item has an alias: key upstop rail. That name suggests a function that has to do with how the keys work. Alex Kerstan, formerly of Steingraeber, ...
I was under the impression that the ONLY reason for these restraints was for moving purposes. Same as for the "key up-stop rail", and the L shaped thing-a-ma-gig under the trap work. Peter Grey Piano Doctor ------------------------------ Peter ...
The tags should apply "slight" pressure on the back of the key frame. This needs to happen in order for the key frame to be bedded properly. Take a look at the spots where the key frame is graphited, and you will see burnishing if the key frame has been ...
.5 mm more realistic. Need to allow for wood movement. Main purpose of dag is to secure key frame during transport. ------------------------------ Parker Leigh RPT Winchester VA (540) 722-3865 ------------------------------
