Edwin, it at least an interesting story,and it's well known that Ford and his friend Edison never tired of talking possibilities
and tweaking stuff that already worked just fine.

I do get the outlined concept.
However it seems at least to me that organs are extremely ornamental decorative.
I get I was pointing out the insides not the outsides.
I have been thinking/figuring out all along with this new position that organ makers are most concerned with the sound. Makes sense and is obvious.
I guess I as a cabinet maker look at a grand cathedral organ and I see inspiring beautiful intricate woodwork as a musician just wants to hear it.
It was suggested to me today by another organ builder/restore I’m doing some side work for that “most organ builders” are generalists.
I will always yearn to be a specialist. My response to his comment was I hope I can find a place within the community to be a specialist. His response was “I think you already have”.. let’s hope he is right.

Explanations of musical instruments such as this make me wonder if the rough uneven surfaces on the inside created a more resonant tone from the reflection of sound waves than that achieved on a perfectly smoothed piece of wood.Butt joints. Tear out. Split wood straight from the hatchet; no planing. Stuff held together with glue and nails or pegs (screws were way to expensive for them in the 1600s). Knots hidden by decoration. Poor quality wood.
And yet, the action on the instruments is superb, even if somewhat crudely made. The sound is glorious. As noted many have survived for centuries. Their goal was to build beautiful sounding instruments; they did what they needed to and no more.

That is a great story Roger. It could even have commercial potential.so... I said that I would provide the sticks next time.
i constructed some 3’ aluminum tubes with a central shaft. At the back is a motor rotating about 10rpm using a 9v battery. At the front is a brass rod threaded for several attachments.

If something was designed to last through 90 days of use but ended up being used for 6 months, would that have been overkill?
Now it is 75 years later and some of them are still in place and serving their original intent.

"Back in the day", the methods available for working with the material were "less diverse" than they are today. Everything had to be worked by hand with blades and saws and that takes quite a bit of effort. So there was little incentive to "finish" surfaces and areas that wouldn't be seen. I suspect that a side benefit is as you mention...the un-refined wood's resonance and reflectivity may very well have been a nice side-benefit. To be honest, I don't put a whole lot of effort into areas and surfaces of projects that will go unseen, myself. That leaves more time and effort available for the "show" side.

Of course they vary in quality. But a Strad always sounds like a Strad and a Guarnarius always sounds like a Guarnarious.
Some instruments are quick and others can't amplify it all.
I find it quite curious, that they could get the same sound from instruments with what has been described as, somewhat random quality construction.
It would seem that minute differences would make changes, yet tearout and crudely cut parts etc are quite random in nature.
I would assume that these days musical instruments are done to extreme tolerances to reproduce the same sound quality in all instruments.
I have no knowledge of making instruments myself, but i do have several customers that make church organs and Harpsichords they use Maka mortisers for precision joinery and supersurfacers for skimming a few thou from parts.
Extreme tolerances ,yes. But the wood is not all the same. This stuff has been studied obsessively for a long time. Clearly
we know more stuff now than they did ....but it's not "the right stuff". Studying the wood and thicknesses of the "plates "
has not yielded enough. Some instruments seem loud but can't be heard in the back of the room. While others seem
quiet close up but can be heard in the back of the hall.
It is possible it could have influence on tone. In general, instrument makers tend to be pretty obsessive about their soundboards. Interestingly, when it was noticed that historical soundboards were not a consistent thickness, it was thought that it was because of the "crude" methods they used to make them, i.e. hand tools, and that they obviously would have preferred an even thickness if they could have achieved it (the arrogance of the modern perspective). After realizing that the uneven thicknesses seemed to be very deliberate, when makers began to replicate them, they realized that it did have a positive impact on tone, and that the unevenness was intentional (maybe people brought up in a craft tradition who built instruments all their lives really did know what they were doing).
The problem lies in that you can infer and copy to excess, and instrument makers tend to be a superstitious lot (and that is from one ), so if copying one thing was good, then copying everything else must be better. Maybe the glue matters (maybe it doesn't), maybe planing vs sanding matters (maybe it doesn't), maybe iron vs brass bridge pins matters (maybe it doesn't). It is wise to keep in mind the story about the daughters and grandchildren who always cut their roast a certain way because "that is how grandma did it and her roasts tasted so good" while losing the history that grandma cut the roast that way to fit her oven, and they would have tasted even better if she didn't have to.
Some thing change the tone, some don't. Since instruments are very complex systems, they tend to defy simple analysis and easy modeling. A common theme on instrument discussion boards is having some engineer come in and say how they are going to figure out the engineering of an instrument and make it better, while all the makers say to themselves "here we go, yet again" (the engineers invariably give up in a few months, too complex they realize). Since it is very difficult to completely isolate the effects of any one variable of an instrument, you end up with normally mild and friendly instrument makers nearly getting into fist fights over discussions of nitro vs poly, hot hide glue vs titebond, fir vs spruce, and so on.
Musical instrument making would seem to be an extremely complex, mystical craft, that originally must have been learned from experience and experimentation, and today I guess that they are still trying to understand all that is at play. There is of course a lot of difference from one piece of wood to another, All quite fascinating!
Andrew, well done. And unlike some instruments , the shapes of violins vary. The immersed truth seekers can discern an
Amati pattern ,or Strad pattern from across the room.
Actually for all the precision in modern instrument mass manufacturing, the instruments often don't sound exactly alike, even for successive instruments off the same assembly line made by the same workers using the same machines with wood from the same tree and hardware from the same batch. Don't get me wrong, in general the quality is much higher, especially for lower cost instruments. It isn't even that they don't necessarily sound good, they just sometimes sound slightly different, and sometimes a lot different. It tends to be more pronounced in acoustic instruments like say a violin, even more so in complex instruments like pianos and non-electronic organs, but even partially or fully electric/electronic instruments like electric guitars, amps, and keyboards can have variance from item to item.
