Super X3. 3600rpm. Sheridan 6"x24" Lathe + more. Three ways to fix things: The right way, the other way, and maybe your way, which is possibly a faster wrong way.
Neil, the guy in your liquid Nitrogen link is my kind, probably Geof's too. Has problem/question, and sets up an experiment to justify or explore.

A great composer for sureOriginally Posted by greybeard
So I'll just have to sit and listen to Sibelius and dream......
You know a fair bit of Finnish history. This got 'a bit' off the topic (sorry) but I'm impressed. I have a buddy from the UK who knows more Finnish history than me.

No, hub, a love of Sibelius plus the ability to quickly read your original wiki quote on the Finnish instrument. I can claim nothing more.
Besides, this is my post so I'll go OT if I want to. It's Christmas, and I'm having one of my usual off the wall ideas !
OK, back on topic.
A piece of plywood with a set of anchor points along one side, and a 1" diam. rail along the other.
Initially, identical weights hung on the end of each wire should produce identical tension, and therefore identical frequency in the strings.
Then run a series of experiments as per Geof's suggestion, changing weights, and use my Korg tuner to compare the results.
I'm not sure about the resolution of the Korg, so can anyone suggest a freeware prog that will turn my pc into a frequency recording meter (ubuntu NOT windoz) ?

OkThanks for taking interest on your part
How many strings do you have? A 6 string guitar will create 'a lot' of tension on the neck. You need to multiply the tension by number of strings. And remember that different strings have different tension.
All of those strings are pulling against wood. It takes time & patience to make an instrument. There is no shortcut.
Also, check that the wood you use has dried for at least a minimum of 5 years.

Number of strings ? - 43 on this one, probably more on the developed one
No neck, unlike the Mountain or Appalachian Dulcimer !
To get an idea of the instrument, and my favorite youtube clip of a dulcimer player have a look at

Nice clip, thanks
That's a lot of tension in total. Every string will pull the wood they are connected to. Even a low amount of strings (6 for guitar) will pull & bow wood surprisingly much. With time of course.
When making an string instrument, adjust & let settle for weeks, adjust again & let settle and so forth until it holds the setup.
It just takes time.. There is no work-around as far as I know.

Very difficult to say because music is so subjective. Years ago I managed to get a professional violinist who was getting into making violins to try composites and he became hooked. I have also read accounts of conventional and composite instruments been played to an unseen audience who did no better than random choice in identifying which instrument played what tune. Of course this was between modern instruments; I have no doubt a knowledgeable listener would identify a 'fiberglas' violin compared to a Guaneri or Stradivarius.
An open mind is a virtue...so long as all the common sense has not leaked out.
I have just recalled a suggestion of using an energising coil to make all the strings of a guitar vibrate continuously as a speedy method of getting the settling in time drastically reduced.
Or did I dream that ?
Building an equivalent for a 43 string dulcimer would be a challenge, but not too difficult, I think.

I bloody great big heavy cast iron frame.
Although come to think of it there may even be a settling period for cast iron because its compression modulus varies with the stress applied.
An open mind is a virtue...so long as all the common sense has not leaked out.
Maybe not. I think this approach is similar in principle to vibratory stress relieving on large weldments.

Found it - the ToneRite must have been the device I read of.
All I need now is to re-design it for a dulcimer !!!
Following that, I found an interesting discussion on Acoustic Guitar Forum - "ToneRite: Results of a scientific test"
where it appears that the device is a straight forward 60hz vibrator.
