Removal of this stuff facilitates reed organ repairs. It is now time to turn our attention to the keyboard, one of the most important elements in a good reed organ repair. You will probably need to replace the felt strips which the reed frame butts impinge right in front of the cells. The *width* of the reservoir cover is determined by the maximum opening of it, *plus* the material glued to the divider, *plus* any material that is folded over on to the face of the reservoir (Mason & Hamlin, usually), *PLUS* some "trim" - at least half an inch.

CATCH RAIL: (Key retainer) A strangely-shaped wooden piece at the rear of the keyboard which prevents the key-tails from rising when the front is pushed down. If the key drop overall is too shallow a thinner thumper felt is usually the best answer. without those inside valves. After all, a reed organ action is only a pneumatic cross-bar switch: the keys (on or off) are the switches, the mutes are the cross-bars. The same will likely happen the first time the reservoir is pulled shut when you eventually re-assemble the organ. The high-back (if present) usually has only a few screws holding it on: these may be driven from inside; remove these, and LABEL them! As screws come in a variety of sizes, so also screw-drivers, and it is prudent to match the two well. Note: The first time you "operate" a freshly covered (and dry) set of exhausters, you will hear fearsome "cracking and crunching" sounds: don't worry: this is glue that inevitably finds its way into cracks and crevices where it isn't needed, breaking loose.

Hold the reed by its butt and tap the tip of it on a hard surface with the reed tongue down: this action will cause the tongue to move away from the frame and loosen any specks lodged near the rivet. More often, though, you are presented with something that has accumulated masses of dirt which has fallen between the keys; some or all of the felt may have been reduced to rubble by moths; and the wires themselves are rusty and/or corroded. Remove the key-slip (in front, below the keys), any lid, music-rack or other items that might restrict access. Once applied, allow it to set for moment or two, then place the valve face-down on the felt, aligning the butt with the piece of tape. Limiting the content to pipe organs, to the exclusion of reed organs and electronic instruments, whether analog or digital, is intentional and the direct outgrowth of the mission of the Organ Historical Society. On the other hand, if the material is folded over on to the face, this can be done now, working the joint down tight, and mitering the corners. It *can* be refinished, though unless it is in really bad shape, I usually leave it alone. But, it has the sound of the days of Little House on the Prairie.

Another way is to use a very straight length of thin metal clamped in position such that it will prevent the blade from wandering too close to the mute itself. Its adhesive fails in a few years. Add Organ. There is usually a seal strip over the hinge, though this *may* go on *after* the exhausters are covered: again, your notes will tell you how to proceed. Reed Organ Society, Inc. - An International Organization. Remove one reed, place it on your work surface tongue up, dip the brush in the ammonia mix, and gently rub away the accumulated material you wish to have gone. Don't rely on memory here: the numbers are often close, but rarely the same, and it's easy to mix them up! The Tracker. Toggle navigation. You will now remove whatever contraption you made up to hold the reservoir open; it will now *stay* open because of the springs, and will stretch the rubber-cloth tightly.

It is possible, if this joint is made with the exhauster open, to pull this joint up too tight, which makes the exhauster want to stay open: avoid this! The company's filing status is listed as Active and its File Number is 802074. VISE: A tool without which no repair shop is complete. As time went on, the ribs got smaller, until in some late instruments there were none. It *may* be necessary to pay a bit of extra attention to the reed butts, where the mute leather has left a mark and possibly some corrosion. Both of these unfortunate results can be avoided by "knowing when to stop": this knowledge comes with practice. Hence this treatise. To learn more about reed organs and related instruments, and about the Reed Organ Society, the Reed Organ Society website contains a wealth of information along with links to other reed organ sites. When it cool again, work the leaves and blow the loosened dirt and rust out with the air hose. If you can successfully remove these without destroying them, label them for re-use: otherwise, make new ones to match the old. (Start with the bass reeds, and work towards the treble).

In so doing, they often created "monsters" that defy easy maintenance and repair. Screws are capable of exerting enormous forces, which can result in great damage to wood when the compressive strength of the parts is exceeded. And that is the topic of Part 14, forthcoming... Wit the keyboard clean and in place on the action, measure the drop of the two keys at the extreme ends of the keyboard. This is the shallow box on which everything you have exposed sits. Trim the excess leather from the dry mutes by placing each one on a smooth surface and trimming with a razor-blade, using the wood as a guide. This has a large area, hence a large propensity to leak wind. Any twist or irregularity must be sanded out, and the active surface re-sized. Once all the screws are found, removed and labeled, lift the upper action up (there are usually small locating pins somewhere) until it's completely free, and carefully extract it from the case (some actions must go out the back of the case, some only out the front, and only you can determine which yours requires!)

[Which end of the screwdriver do I use?] (Some early organs and melodeons did not use bushings on the key pins" excessive wear on these is difficult to reverse: consult an expert). Make some sketches of how the ends were done. Its valves have been removed, their facings cleaned or replaced, and returned to their original positions, and the reeds have been removed, cleaned, and replaced in their cells. Find the exact center of this piece, and make a heavy pencil line across the piece. All of the above must be done twice, of course. Use plenty of glue, and maybe work it through the cloth with a smooth wooden spatula. Attention is now turned to the "stickers", which were removed long ago and which have been kept in order. - music. To do this with good permanent results, the end of the sticker must be sealed (it is endgrain, and glue will soak into it very quickly) before the first dot is applied. But an organ stored thus is likely to have MANY more problems than one that's been at least kept dry and free of rats, mice, moths, and wasps. However, the frame of the reed (save the area occupied by the tongue itself) is only a "support device", and while it may please one's aesthetic sensibilities to have this all shiny and nice, the effort is not necessary, and polishing in this manner compounds your chances of doing major damage to a reed tongue "by accident".

This treatise is intended for those who are tempted to fix up "Aunt Maude's old pump organ"that has languished in the attic since Maude went to her reward. You need to make up a little "jig". Lift the tip of each spring and place it *alongside* of its valve, resting on the soundboard. If this is all that's required, the valves can be placed back in their original positions after the cleaning described, to be held in place as before by the original springs.

Next, you need to observe carefully exactly how the material is applied, especially how it is "closed" at the hinge end. The organ may just need a good cleaning and a few adjustments. The next step is pretty obvious: you'll wrap first one end, then the other, gluing both surfaces first. Only when this condition is met will a screw (regardless of the type of head) create the kind of compressive force between parts which it was designed to do: if any part of the screw impinges on the part which will be under the screw head, inadequate compression will be obtained, and slippage of the joined parts can be expected. Modern screws are formed in dies under great pressure from blank billets, and are generally crude when compared to old ones. Resist the impulse to oil them, as this invariably only works for a while. The sixth - and most common - deadly sin is that of "munging" the heads. First, place the piece of felt for notes 1-13 on a flat surface, and hold it in place with masking tape at the ends.

A round-head screw, on the other hand, bears on the material directly, and the head remains well above the joined surface. Next, apply glue to the end of the exhauster cover, and pull the cloth up into position, leaving the ends to "flop around": the correct position of the cloth allows space for the rib to lie flat on the inside when the exhauster is closed. It was very successful, with attendees from as far away as Europe and Japan. In this situation, the keys must be removed from the frame before the stickers are lifted out.
