Steel wire in tension

Väinämöinen makes the first kantele from the jawbone of a giant pike

OK hub, when are you going to build one ?
Getting the giant pike to lay on the bed of your cnc might be a problem, but that's what makes life interesting.

I hope some day I will build a few (one working after the few failed prototypes as usual).

Even more challenging than fixing a giant pike to my CNC is to find a giant pike.. I've fished all my life, no giant pikes so far...

Also, CNC would only be of little help.. Mostly manual work by hand.

But if you had one of these.....

Go modern: Make the frame from carbon composite, much higher E, particularly specific E, and less hysteresis than wood, also not as much creep.

Just a thought on stress relieving. Easy to try.

Put strings in a small amount of liquid nitrogen in some styrofoam.
The liquid will boil.
Cover and allow to slowly return to room temperature.
You could dry ice to similar effect.

I am no expert, and this may do nothing, but it might do something.

This is where I am leading...

Geof - thoughts are in that direction but lots to learn first.

Would fix a few problems but I'm not sure the sound would be that great..

Ouch... but interesting.
Thanks, Neil.

But then the pike jaw sounded great.

But then the pike jaw sounded great.

So the story goes. But nobody confirmed it
And impossible to prove:
- no giant pikes.
- no willing maidens.

So I'll just have to sit and listen to Sibelius and dream......
