Hi guys did anyone try to replicate Davey's heater? I tried with two bicycle bells but freq of my generator don't think goes above 440hz. Any ideas?
Thanks

Bike bells are small; hence high fequency needed.
Go to a kitchen supplier and look for some cheap stainless steel bowls,
properly spherical (no flat base to sit the bowl on). The key is to buy
bowls with a frequency a shade under an octave of your mains frequency,
i.e.
in the US, 60, 120, 240 cycles per second
in the UK, 50, 100, 200, 400 cycles per second.
You could go in to the shop with a set of pitch pipes for guitar tuning
and estimate using their G. Here are the notes/frequncies Frequencies of Musical Notes
Simply hold the bowl upside down with your forefinger (or better still,
a pencil) in thwe middle, and strike the rim.

I found a schematic of a simple frequency generator and I'm going to built it. It seems it can go high enough to try on bicycle bells.
Hope this works.

Try it. But I suspect that the closer we are to the actual frequency
of the mains power, the better. I am looking for woks.
If you can find a musician to help in the tuning, so much the better.
It is not as easy as one might think because there are several frequencies
ringing away.
Also, bear in mind that the final grinding of the rim should be done when
the bell is installed in the gear to be used. This is because removing the
bell from the grinding gear and installibnig it in the running equipment is
likely to change its frequncy by a small amount.
Have you gor a Variac? It takes away the need for courage when you
pour water over the equpiment, and then push the plug into the mains.
Ebay have them.

Hi Wrtner I am a musician and a classical composer don't need others to tune the bells . Ok as Davey did he used to resonate with only one bell; after he found that two resonant bells worked better but with one worked fine.

Good news about your being a musician since tuning four octaves apart is
harder than it looks. If Davey used one bell initially, how did he connect
up the mains voltage? Are you on 50hz or 60 hz?

Davey used two bells not one but at first they were two different notes as I understood his document rightly and still worked on resonance with one bell.
After he did two same notes.
I am trying to use a frequency generator on 12v battery and going in resonance to the bells although today I tried it but nothing happened

Surely, the main point of Davey is to use your electricl mains
as the source of the frequency and the source of supply.
The bells are then tuned to that frequency (or an octave of it).
Thanks WEthepeople for posting those photos sorry for taking long to respond cause now I saw them.
I tried my freq circuit but something went wrong and blew my 555 I should change it. I think it's essential to tune both bells.
Thanks
