You will see in the photos a new way to do a resonator. Is a copper/nikel soldering rod tin soldered on the inside of the brass bell. It makes an interesting sound. I will try to put inside how many I can.
Neat, looks as if they work like tuning rods resonating sound.
I don't know if is necessary a bisquit, I just soldered a brass bridge using the minimum possible tin, and it works. But maybe is better a more large soldering to transmit the string vibration to the body ? Or is better a wood buscuit? The brass is 1 millimeter thin, but is quite rigid. I will solder inside a vibraphone :-) it's no easy, but is a lot of fun.
This is the overall design. The wood around the "bell" will act as a megaphone
Now I have soldered inside 3 ft and half of bronce. The sound is something never heard, a little bit of Sitar. I make my experiments with one single string, I've noticed that there is more time of vibration. I feel myself like a medieval alchemist, tomorrow I will try with a much more "solid" wire.
Great, if you can, load video sound bite of it.
Today i've studied. I discovered the existence of the "Dulcitone" a kind of piano with no strings, but with tuning forks instead. There is one in a museum in New Zealand. And studied the phisics of tuning fork. Very interesting. Then I try another variation, but it does not work, see the photo. Ihave soldered right down the bridge, but is deaf. I have to try with a real tunig fork, as i find one i will try.
I put a snake inside, his eye is looking me :-) I'm on the way making two identical guitars, one with the snake, one without. Be patient, as finished I will record both with a good microphone. The eye is glass, a big "murrina" from Venice. The snake is copper tube hammer flattened.
