Old piano advice needed

I would appreciate any possible assessment. This piano has been stored in a warehouse for 13 years with fluctuating temperatures and no stable humidity levels. However, it was kept dry. Before being stored, it was apparently professionally refurbished.

All keys play cleanly. The dampers press smoothly and properly. The notes initially sound fine, although of course it is out of tune. No rust or major visible damage is apparent.

Could you provide any insight into its condition and what kind of restoration would be necessary to make it fully playable again?

I would be looking at around €1000 in transport costs. Would it be worth investing time and money into this? Unfortunately, a professional piano builder cannot easily inspect it in advance.

I would be very grateful for any advice.

Dampp-chaser piano lifesaver system

Has anyone used this? I'm thinking of getting one to control humidity around a piano which is kept in a very dry room

Pin Block on Restored Knabe

Have any techs or restorers seen a pin block used in a restoration that has old holes plugged like this? This seems strange to me. It's pretty beat up and this was consistent all along the block. First, I'd expect a new pin block. Second, if they reused the original block, why? Third, when reusing the block, how could they make holes in new locations unless they used a different plate? Fourth, is it common to use a different plate in a restoration? Up top, the pins were angled towards the tail, unlike what we normally see as angled toward the keys.

I wasn't impressed with the quality of the string work, either, so maybe the whole job was subpar.

Excessively heavy key weight on Boston grand piano?

I’m curious if anyone here has experience with unusually heavy Boston grand actions. My piano is a Boston grand that’s less than 5 years old and kept in a stable, well-regulated environment (so humidity/swelling shouldn’t be the issue). The action feels dramatically heavier than other grand pianos I play — especially compared with the piano at my school, which I can play for hours without fatigue.

I tried roughly measuring the touch weight by placing U.S. quarters on the front edge of several middle-register keys (Middle C, D, F) until the keys would slowly depress. It took about 18 quarters per key, which I think works out to around 100g of force. From what I’ve read, that seems much higher than normal.

The main issue is that my forearm gets pretty tired after only ~15 minutes of playing on this piano, whereas I have no fatigue issues on other grands. I recently had the piano serviced by a Steinway-certified technician, and he told me the heavier feel is basically due to the geometry/design of the piano and that there isn’t much that can be changed.

Does this sound normal for a Boston grand, or does it sound like the action/touch weight may genuinely be excessive? Has anyone had success making a Boston action noticeably lighter through regulation or action work?

Can this Serial Number Plate be taken at face value?

I am wondering if indeed this piano was manufactured in the U.S.A. (let alone Loveland, Ohio) (That s/n is 1560824).

Are these hammers worth filing?

Bought this 1894 Steinway A the piano actually sounds great and bright. I was hoping to have hammers filed before replacing the whole hammer assembly( they are making some noise), but also afraid the piano would sound like a different instrument with new hammers. My tech told me they have about 20-30% life left of the old hammers

Finally got a piano to tinker on- advice?

Spent today cleaning it and seeing what was wrong. Im not sure what to do abt the warped key ivories; the biggest issue is the bridle strips you can see in 3 and 4. Should I just bulk order some and replace them all?

Is there anything glaringly awful I'm missing? Any advice on how to tackle this?

All the notes are a half step flat lol.

Do Kawai pianos generally have a lot of reverb?

I was given an upright Kawai from a family friend and I find that it has a lot of reverb which lasts for about 5-10 sec until it’s fully silent. But it’s a bit of a haunting reverb, like echoing through a dark tunnel.

Was curious to know if this is a Kawai trait or maybe is a result of lack of maintenance from previous owner? Is this maybe something that can be fixed?

Someone on here recently posted and was annoyed about a very mildly messy string coil. This one's for you. This may be the worst I've ever come across. So far...

Highschooler Can’t Attend PTG Convention w/ Stanford Conflict!

Hey all! I am currently a high schooler (can drive and commute) near the DMV region. I am looking to be a piano tech right now, as a gig in college, or as a hustle in the far future. Unfortunately, and fortunately, I got accepted into Stanford’s summer program and conflict what I originally wanted to attend the PTG convention in Arlington. (Have not registered yet) Does anyone in the region know any other opportunities? Any way I can get into this field? If I would wait another year, I would almost be shipped off to college by then. Thanks all!

Built a tool that turns song links into playable piano sheet music — would love feedback

I’ve been learning piano for a while, and one thing that always frustrated me was how difficult it could be to find good sheet music for certain songs — especially modern ones.

A lot of the time, the arrangements were either oversimplified, expensive, or just didn’t exist at all.

So I ended up building Sonata, a small app that converts song/audio links into playable piano sheet music automatically. The goal was to make it faster to turn songs people already enjoy listening to into something they can actually sit down and play.

Still improving the transcription and arrangement quality, but I’d love feedback from piano players or anyone interested in music tech.

If anyone’s interested or has suggestions, feel free to comment or message me.

Upright piano keys stuck after reinstalling action (broken bridle tapes)

Hi everyone,

Just to be clear, I’m not a piano technician at all. I only had one stuck note on my upright piano and thought I might be able to fix it myself, so I removed the whole action.

The piano already had a few broken bridle tapes before I touched it. After putting the action back in, the notes with the broken bridles don’t go down anymore at all.. the keys feel completely stuck.

Did I probably reinstall something wrong, or can broken bridle tapes cause this after removing/reinstalling the action? I read that maybe the jack can get stuck under the hammer butt, but I honestly don’t know enough to tell.

Does anyone know how to fix this or what I should check first?

Thanks a lot.

Rattling snare-esque sound

I noticed this piano makes an almost snare drum like sound, kind of rattling, kind of like speakers playing too loudly type sound.

comes from left side of piano definitely, can feel the vibration occurring on left side of piano.

the interesting bit is it only really happens when I press middle C.

couldnt find any loose hardware or components.
