Repairing Deleika 20-key Organ

Finally a topic for me :)

You must have a strange feeling about "fine-looking" things -- there's indeed lots of music for this scale. (And hopefully more soon, if Robbie gets to work ;)

Well, that is nonsense: this organ never _had_ enough wind.
You say the organ is a few years old. As I know Deleikas, they all have these problems, for those organs are not of a good quality. Indeed, I have to say that they probably may have learned meanwhile, but those early organs by them are really unworthy to buy, unless you haven't the possibility to buy a better and expensive one.
The problem of having little wind, and not being able to play slower or having fermatas and so on, is also a problem for the little 20-key organ of Mr. Raffin. As you may have seen, there is a picture of me with the bigger one ("Konzert") on the foxtail ftp archive. This type of 20-key organ was built by Mr. Raffin exactly because of this problem.
If you look into your Deleika, then you will see that there is only one "pump" to get the wind. A friend of ours asked if it would be possible to have a double-pump-system in the little 20-key organ. So my father asked Mr. Raffin for this. His answer was that there wouldn't be enough room in the little case of the little 20-key organ.
We said: "Take a bigger case."
"Well, then you have a double-pump-system, but what about the space inside the case -- it would be quite empty."
"No problem. Put some registers in it!"
That's the whole story of the "Konzert" 20-key by Mr. Raffin, which is meanwhile one of his best.
This organ really is a dream for all those people having lots of 20-key rolls. You have registers and you have enough wind. But let me tell you, if you need more wind and have few rolls, you really should think about taking a bigger one (perhaps a 30-key), and don't think you must take a Raffin only 'cause I said so. (If you do, tell him I told you to do so.)
There are lots of fine organ-builders. Some would even create an organ for you the way you want it to be. For my part I have to say the roll- system to be one of the best, because of the little space these things need.
(In the picture of me, there is a case to be seen on the left-hand side; in this case we can carry about _30_ rolls containing two to six pieces of music each).
However, you are free to take the most favourite system of the French: book music. You saw them for the Le Ludion organ. They are a bit better for playing-techniques. Rhythm and concert nuts are better served by that, though.

-- plus the two bass-pipes (doubled) on the left and right of the displayed ones. The division for melody and accompaniment for the "Konzert" was told in one of the MMDs of the last days.

Hee-hee! Okay, unscrew the top of the case, then you can take out the front easily. (I know the system, for Deleika copied it from Raffin). Now you can see the two bass pipes. They are doubled each with a second pipe. If you really want to do it, you can divide them, so you have two pipes less and perhaps a little more wind; but take my words: you can do a lot, but you can't change the fact of having not enough wind.
The only, really _only_ way to get more wind in this "thing" is to take an old vacuum-cleaner and try to get the wind-creating-part of it inside of that case. You will need electricity then, and it makes lots of noise, but you will have enough wind and you can play as slow as you want.

There you are! That's an organ!!!

Sounds not very enchanted ;) [ It wasn't. -- Robbie ]

Yes...
