Hello everyone,

Last weekend my daughter and I were playing the piano. After a while one of the keys got stuck and didn't come up anymore.
I have a Roland Kr 570 digital piano. The keys are weighted to imitate the effect of a real acoustic piano.
However YouTube was my best friend to dismantle the piano and find the problem. A hammer was broken. So I took this part out. Searched I while on the internet. And found a nearby store which had a replacement part.
So I thought I fixed the problem.
However this Pianoguy told me that if one of these part snaps, it was likely that others will follow. So I bought a spare part as wel.
I thought that would be a smart thing to do.

Now you see the problem is, that when I got home and inspected the other hammers they all were about to break. This pianoman was right!
I would need to replace them all. That would cost me about 14 euros for each hammer. Big bummer.... you can do the math on 88 keys times 14...
The piano is 20 years old. But I really would like to play this one again.

So are there people amongst you, who would happen to have a Roland model with the same hammers, because there are more models made with this hammers. But yours is broken and just standing in the garage I really would like to get my hand on second hand parts for my piano.

I hope one of you is able to help me. I already contacted Roland, looked on Ebay and tried several pianostores in Holland, UK and US. Also got info about 3d printing this parts. But all these options are really expensive.

Looking forward for your reactions and comments. I will try to include a photo of the broken part.
I need the hammers for the black and the white keys. These parts are a little bit different from eachother.

I didn't know that Roland had major problems with broken hammers. I remember reading about frequent broken keys. But not hammers.

If you can buy another Roland with the SAME action parts ...
one that is MUCH newer than yours ...
but available for cheap (perhaps because the electronics are blown) ...
then you could use that piano as salvage.

Short of that I'd have to say that it's time to buy a new piano. Count yourself lucky to get twenty years from the old one.

Maybe the weak point could be reinforced with some epoxy glue(?) There are more liquid ones and then those Play-Doh style ones.

I think finding a spare to scavenge from is indeed your best bet. The piano is so old that "new" spare parts will be very hard to come by (and as you've discovered, they not any cheaper just because they're old). Good luck!

Thanks for your reactions and suggestions.

It's a mayor issue for Roland digital piano's in this age. All the hammers crack due to a real simple concept of a little bit of plastic and a big piece of metal. I also learned yesterday that the Elco's will leak overtime and this courses weird sounds and crackling noises. Or if you want to take the volume up - there is a grrrr sound, because of a failing podmeter. All common failures overtime. 20 years back it was a state of the art piano... with a composing function and a real floppy disk! And oke technique improves overtime - so with a little bit of TLC and love this will come round again.

Yes the epoxy suggestion, was also in my mind. I think that will be the quickest solution for now.
Overtime I can trie to find a spare one.
However I hoped that this platform could help me at spare parts. Not from a parts store, because I will pay a big price aswell. But from anyone who has a Kr570 aswell.
