How to Repair Loose Tuning Pins On a Piano

- Piano pinblocks can loosen up over time. Sometimes, they can become so loose that the piano is un-tunable. There are several fixes for this issue that would otherwise render the piano useless. This video focuses on one remedy in particular.
Excellent info and demonstration Mr. Larson!
Thank you!
Thank you so much for the video and sharing your knowledge and experience. I bought a petite baby grand that is about 80 years old. So far it only has one or two slipping pins. Your suggestions are all ways that can avoid having to replace the whole pin block which is so expensive. I could hear you fine by the way and I enjoy your other videos too.
Excellent video! I have been doing this for years as well with 100% success. I keep medical syringes and needles on hand for this purpose. An ultra thin 1.5" long needle with medical syringe allows for an almost entirely unnoticeable fix. Thinnest glue possible is a must for this type of fix.
Thank you so much my friend how are you I didn’t see you last NAMM I just acquired a Steinway model C 85 note this piano is basically an 1876 and I am replacing all of the strings including the pins and I noticed that the pens are a size 6 I think that the size 6 is the highest it goes
When I ordered the new pens I’m gonna order the same size and less of a have a size 7 but if not I will definitely try this technique the name of the glue you mention is called CE glue I have to look it up and see where I can I get it
Thanks again Brigham
Any fluid, whether glue or oil, will only penetrate 2-3mm AND damage the wood. The correct thing to do, is to replace the the pin with a thicker one.
Cyanoacrylate adhesive - "superglue" - will not damage the wood of a piano's pinblock. It reacts strongly with the cellulose in the wood, to form a new compound. This technique has been in use for over thirty years now, and is often the method of preference, especially where the piano is one of no financial value and would not justify the cost of a rebuild. Where a piano has most or all of the pins quite loose, it is impractical to talk of replacing with thicker pins. Superglue has rescued many an older piano, keeping them tuneable and playable, where they would otherwise be scrapped.
@@DavidBoycePiano That is chemically NOT true! You deliberately damage the wood! The only correct solution, is to replace the pin with a 0.1mm thicker pin. Every properly trained tuner and technician will know that.
@@gawiewolmarans3813 Chemically NOT true? Not true that cyanoacrylate reacts with cellulose? I am interested in your assertions. What do you do when you encounter a piano of little or no monetary value where most of the tuning pins are loose? Replace them all? I wonder that you can so readily write off more than thirty years experience of wise and experienced piano technicians.

Thanks for this video. One question I have is: how long after application can I start to tune (at my customer's home)?
I would recommend using a wireless headset microphone during recording. Reduces noise floor (room noise) thereby improving the audio quality of your videos.
Excellent suggestion. That's how a zoom lens ruins the sound.
Information is good, lighting could be brighter. I think your pipettes have a little drawn out material at the bottom like most of these disposable pipettes do. I build a lot of rc models and we use a nylon short tubing that has been drawn out to a very long small tip, you can get them on Amazon for 7$ for 200 and when we build our airplane models we can push these right on the super glue bottles or your pipettes like you are using and they provide very precise control of the glue and if they get plugged you can just snip the tip off. You never contaminate the glue bottle by placing your disposable pipettes back in the bottle when its just pushed onto the glue bottle spout like with the Bob Smith cynoacyralate super glue.
I love you. I'm happy again, Thank you so much!
If only some pins are loose, would gluing them all make some of them too tight?
We haven't had that problem. We've been doing this treatment for years and have had great success with it. CA glue is very brittle and it does an excellent job to fill in all the gaps in the wood, and the wood sucks up all the CA glue around the tuning pin much like a paper towel would soak up water. When you tune after, it will make a bit of a cracking sound, because you are breaking that glue seal, but it does not affect future tunings. You can even do another CA treatment 5, 10, 15 years down the road and it still works great!
An otherwise great sounding/playing piano with slipping pins (especially a Grand Piano) DOESN'T need to be scrapped! It CAN have it's pin block replaced (time consuming and expensive). An otherwise really good piano is worth it.
All that effort and not placing the camera where we can see where you're putting the glue! Or putting some light on the scene. Nice explanation, though, so it's still useful. Especially the part about the glue expanding the wood fibers. Thank you.
I think they are called super glue micro tips on amazon
Terrible video, sorry. Way too much rambling. Microphone needs to be on your shirt. Terrible lighting. Can’t see base of pin …. which is the whole point of your story!!
I agree with Buss Boy. Dude you would have started that video after the first 7 minutes! I don't know if you were stoned or whatever....but please think of what you are going to say before your camera man pushes the record button. Not afterwards!!!
that is so bad in so many ways!!! people , don ever put any kind of liquid on the piano pin board
I know this is an older video so I don't expect a quick response but how does this work when you have a cork bushing in with the pin? Does the glue get used between the pin and bushing or between bushing and plate/pinblock? Thanks in advance
Do you think this would work with a 1976 upright Hobart M. Cable?
Mr. Larson, I really appreciate your video. I have a couple of questions, though: Is it my imagination, or did you actually attach a tiny little filament to the tip of the dispenser? And, the other question is, how much longer can I expect the piano to be in tune? I just moved into the country in Mexico and the local tuner sucked, so I asked my personal tuner to come, and ended up giving him much more than I have ever paid. Now, it´s time for my second tune and hopefully I´ll be able to use this info to keep a steady sounding piano longer.
No filament. It should stay in tune well after, just needing yearly tuning. We have had some instances where we needed to to an additional CA glue treatment, but it works well!
Good, the guy'll be here tomorrow. Can't wait to try this. I guess, in a few months I'll let you know how it all went😉
@@ezequielmartinez2825 I hope it works great for you!
@@brighamspianoservice Hello, Maestro, hope you´re doing Ok. I wanted to share with you my story. It´s been about 8 months since, literally drenched the pins in CA glue and a piano that needed tuning almost every two months is firmly tuned, which translates in a lot of money saved, thanks so much... Now, I have another question; hope I´m not being a nuissance. How likely do you think it is to set the (studio) piano on a camper or motorhome and travel around? I´m sure CA glue will help me a good deal, but have you heard of anyone doing it?
I saw that too. It looked exactly like a filament. I'm very surprised no one else saw it. How is that possible??? The only thing I can think of is dried glue that hardened midstream. But CA glue doesn't harden that fast. Mystery of mysteries.
Great video and information! I have a quick question about it. My tuning pins all have wood bushings at the base. Should the glue be placed between the pin and the bushing? Or outside of the bushings? Thanks!
Most tuning pins have wood bushings. You can do either. The glue will saturate it all over.
okay so, i have no found anything to the problem im having with my piano.
my piano is a grand hamltion ( i think baldwin ) piano and, i press down on the sustain pedal and the keys don’t keep ringing
aka: the dampers aren’t lifting up.
this piano is quite old so*
it was working a few months ago
until something popped off it
it was a U shaped nail
and im not sure where it is now but
i neeeed help lol
Your regular tuner-technician will be able to help.
Thank you so much for the great advice
