You might wonder: just what IS there to restore? Can't you just hook it all back up and play?
Wishful thinking. Very wishful.
As mentioned before, this organ is an electro-pneumatic organ. Part of it is electric, the other, pneumatic.
So what has to go?
Basically, EVERYTHING!
The pipe chests have inside them valves , pouches and armatures. All rotten, because they are leather, except the facings on the armatures: that is blotter paper. It all rots with age, and starts flaking and falling apart. Components lose the air-tightness that is so necessary.
It is a LOT of leather, and not just ANY leather. You have several types inside the action. Pouch leather, valve leather and gasket leather. Each has different qualities and thicknesses.
Each STOPPERED wooden pipe has to have the felt and leather on its stoppers replaced. And replaced CORRECTLY. The stopper has to exhibit several qualities: it MUST seal completely against the inside walls of the pipe, or the pipe WILL NOT speak correctly. The stopper -even though it must fit snuggly inside the pipe- must still be free enough to be moved slightly up or down inside the length of the pipe so as to tune the pipe. Each stopper has a handle, much like a toilet-plunger handle. To make the pitch of the pipe HIGHER, you push the stopper IN. To make the pitch LOWER, you pull the stopper OUT.
More leather is used on the large bellows which move the shutters. Leather on the pneumatics inside the blow boxes. Leather and felt are everywhere. And it is rotten.
Then there is the electrical wiring. The organ has a rectifier which transform the 110 volts ac power into 12 volts DC power. MILES of 26 guage ( really SMALL) wiring runs all over the place in the console, it goes through the relays and out to the pipe chests. And it must go, not that it is bad, but because the original insulation was cloth. Cloth is not allowable anymore, even if it IS just 12 voltsdc.
Okay, skins and skins of leather, yards of special felt, miles of wiring...
Each wooden pipe was finished with orange shellac. It is flaking off. The old must be scraped and sanded off, and new orange shellac applied.
It is a MASSIVE job to do a thorough restoration.
I am EAGERLY waiting to really get to it!
