One of restoration’s more time-consuming tasks is preparing replica parts: pitmans, pouches, valves and other small elements of electro-pneumatic action. Attention to detail results in work that gives the best operation, good margin of adjustment and a long lifespan.
Missing or mangled equipment? In a restoration project, we attempt to make new components so that they will assume the appearance of the originals, for uniform appearance and sensitivity to the builder’s aesthetic.
As with our parts, materials, glues and finishes follow in the spirit of the originals. For example, when providing new components for Skinner and Aeolian-Skinner organs, we use No. 1 grade California sugar pine, finished in orange shellac; in a Kimball organ, however, we would build from straight-grain white pine finished in clear lacquer.
LEATHER: We use only the finest and most durable skins, based upon current research, our own experience, and that of colleague firms. Leathers are chosen with regard to application, pressure and desired tensile strength. Chrome-tanned sheep skins are generally used; Kangaroo leather is available by special request (check for availability and price). Valve leather is double-buffed for good glue adhesion and valve seating.
PAPER and DISCS: Fiber discs are used for all pouch work.
ADHESIVES: Water-soluble hide and fish glues are used in all cases where a perishable part is attached to a permanent element. Non-soluble adhesives are used where firmness of adhesion is desired and future renewability is not an issue.
FINISHES: We finish all parts as befits their application and original construction.
METAL PARTS: Springs and valves wires are replaced with the best quality available.
