Short Mountain Music Works Restoration of Pneumatic Player Piano Actions, Organs, Organettes and Orchestrions Restoration of Barrel Pianos & Organs. C.

Conversion of instruments, like Accordions, drums, and other percussion to pneumatic operation. CUSTOM FABRICATION - RETROFIT
There are many rebuilders across the country but few are equipped or experienced enough to deal with complete remanufacture of parts that may be needed in the restoration process. More than half of the shop space here is devoted to wood working equipment. I have had many ye

ars of training under Amish craftsmen in the art of working wood. My goal is to provide the highest quality workmanship in the copying and fabrication of quality player actions, pumps, and pipe chests, in part or in whole. Stacks and components
Often times, player actions are missing, or have been damaged or cobbled to the point that they cannot be restored. There are player actions like Gulbransen, H. Bay, which are glued together and cannot easily disassembled or serviced . Actions like Schultz, with its inner pneumatics, or actions which have flaws in their design that appear with age, can be redesigned to be easier to service and inexpensive to rebuild the next time. Then there are the stacks that contain parts that are Die Cast (pot metal), or no longer available. For this, a player action can be custom made to occupy the same space as the original. In coin pianos, stacks are often missing or replaced with a different one. Having an exact duplicate of the original stack can increase the value of the instrument. When making a stack using the best grade of well seasoned hardwoods is very important. I try to use the same species or similar woods that were used in the original. The woods I work with generally are Poplar, Maple, Cherry, and Birch. Once I purchase the rough lumber I need for a certain project, I need to let it sit in a humidity/temperature controlled space for at least 3-4 months before I can begin milling it. Keep in mind this makes the turn-around time for a complete stack 7-16 months. Once the milling and drilling is done, the holes and other air passages are sealed with burnt shellac as in the originals. All gasketing, pouches, and valve facings are leather / zephyr skin, NO SYNTHETICS. Brass, steel, or nickel plated screws are used when ever possible. Below is a list of some of the stacks and parts I can make. I don't usually have many of these parts in stock, but I do make extra when I do a custom run of certain items. I will be adding items and information to this page periodically. Please bookmark this page and check it often. If you have any special needs not listed here, feel free to contact me. Complete Stacks

Pumps
Almost every foot pump bellows unit from a player piano or reed organ that comes into the shop nowadays needs some sort of extensive repair or replacement of wooden parts and bellows boards. The three-layer plywood used in most of the bellows is very susceptible to delaminating under adverse conditions. Trying to re-glue this mess poses a few problems; remaining glue joints are weak which will not hold, and may not allow full pe*******on of the new glue, and swelling and contracting of the laminates may cause internal cracks or misalignment of screw holes and channels. For these reasons, it is more practical to just replace these parts. There are two ways to tell if delaminating is present. - Thin vertical cracks in on the face of the board, particularly around the flap valve holes where there may even be sections of the top laminate missing.
- Sides of the boards show variations between the laminates, where the outer laminates have swelled and the middle one has not or visa-versa. There are a few makes of players where adding electric unit is impossible because the pump takes up the whole bottom of the piano. In this case a whole new foot pump can be made, using the original hardware, that would a accommodate the suction box. Case Work & Cabinetry
As stated in my bio, I have had much experience as a cabinetmaker under the tutelage of Amish craftsman. I have the equipment to handle most any type of general cabinetry, be it duplicating a band organ case or extensions for a build up orchestrion.

Challenging Project
This Rudolphe Fils Harmonium came into the shop last month. This organ was almost identical to a Christophe we restored earlier in the year, the only difference being this model has a transposing keyboard. We had rebuilt this instrument about 12 years ago, fabricating a whole new bellows unit. When the new owner pulled it out of storage, many notes were syphering. On examination, it was found that the top laminate of the reed chest had cracked and separated from the cell chamber below. The only way to properly repair was to completely remove the top laminate using our newly acquired CNC router. The first step was to accurately measure the position of pallet and screw holes. Massimo set up the router to operate with LinuxCNC and used FreeCAD to draw a model of the top board. A script was written in Python to automatically space and position all the pallet and pin holes in the 3D model. The routing and drilling pattern was then generated and exported as gcode, which contains the instructions for the router. The new pallet board was milled from ¼” Baltic Birch ply which was slightly thicker than the original. The next step was to use the CNC router to completely remove the old soundboard and enough of the cell chamber to accommodate the new soundboard. This was done in multiple passes, (.03” each pass) to avoid tearing out the cell walls. When finished, the pallet board was doweled in to place so it would not move during the gluing process. The type of glue is of the upmost importance. Our choice is Cascamite, which can be mixed to any consistency, (consistency being very important). The main advantages are that it sets up very slowly, and cures extremely rigid, which is ideal for laminates that require a complex lengthy clamping procedure. After a day, the clamps were removed, edges were trimmed, surfaces sanded and sealed. When the organ was fully assembled, it played beautifully.

Complete replacement of a bellows unit -
We have been restoring quite a few reed organs recently. Most have been worked on before, some severely butchered up. . Here is an example: Bellows cloth glued on with Elmer's, then tacked down with a gazillion staples, cracked panels, badly patched, along with replacement oversize cheap zinc plated screws. In these cases it is sometimes more economical to make new parts. For bellows boards and panels, we use high grade Baltic Birch ply, which is very stable. The pump is for a vestry style "Pearl" c. late 1880s.

We've just started on an English parlor barrel organ made by Flight & Robson c.1820. Most organ makers seal the bellows boards with plain kraft or news paper. Some how, this maker had access to hand written music scores which was pasted on the boards.
Another unusual feature is the way excess air is exhausted from the reservoir. Instead of the normal pallet that opens to release pressure, this system has 2 pallets that open into the four pumping bellows, dumping the excess, which is released on the exhaust stroke. The advantage here is when the reservoir exhausts, there is no "pssst" sound it is completely quiet.
This organ was restored in the late 1800s, but it looks like they didn't bother replacing the flap valves which are blackened and totally petrified.

The Christophe Harmonium of which I made the bellows for is completed. Made around 1900, it has one and a half ranks of reeds. One unusual feature. There is a stop called Expression. This cuts of the air flow to the reservoir so the organ is played directly from the bellows without regulation. It has a very simple tremolo that works very well.

Pictured here is a bellows unit for a French Harmonium made around 1900. This has been reconstructed almost entirely from scratch. Many of the boards were warped or cracked. The unit sections were glued together which made disassembly impossible without damage to the pieces. Interestingly one of the panels was sealed with newspaper, Les Droits de L’Hommes, which was published between 1898 - 1900, making the organ easy to date

Here is a pre-restoration video of a "Longman" English parlor barrel organ made c. 1820. Seven of the pipes are badly damaged so it is missing notes. It bears the business card of a John George Fuchs, "Dealer in Orchestrions, flute & trumpet clocks. New York City." My guess is that he rebuild it in the early 1900s.

Pre-Restoration - Longman barrel organ c. 1820. Has a few damaged pipes so it misses notes here and there.

Reithhofer/Carl Frei organ report:
As reported previously, we have re-manufactured the bass, accompaniment, and two counter melody pipe chests. We saved the most complex for last, The Melody chest, 23 notes, 5 register cut-outs. After months of work, it is now complete. Like the other chests, it was warped, cracked and dry-rotted. Its extra width was a challenge as well as the split air channels in the front half of the chest. Instead of drilling out the channels as was done on the originals, I opted for using a laminate construction and cutting the channels with the pin router. Further descriptions accompany the photos

Looks like we are branching out!
We were servicing an Ampico grand for a customer, who asked us if we worked on juke boxes. My partner, Massimo who is going quite heavily into Electronics, took the job on. Here it is in the shop. Massimo got it playing, but it needs cleaning and TLC.

R.A.M. uses the "O"roll for about all their instruments, which is not very compatible with a 42 note calliope, since the roll is designed for piano/orchestrion with a 60+ note range. The octaves at both ends are coupled, Some arrangements don't sound too bad,

About month ago, a customer showed up with a cabinet he had built and multiple boxes of parts, a calliope kit, made by Ragtime Musical Instruments, a.k.a. Ragtime West. I really don't care for this company's products. It's all plastic and cheaply designed. The guy was desperate. He had competed a carousel, with animals he had carved, and the grand opening was the weekend in June. We dropped everything and were able to assemble and get going on time. I had to re-make all the percussion pneumatics, and modify the drums, as the heads were not tight enough, and provide the electrical system.
