I think probably 1/2 of the (area) of window screen would be considered solid rather than 1/2 of the dimensions both ways. If the orig. dimensions were 20 x 10 inches that would be an area of 200 sq. in. Half of that would be 100 sq. in. The above only assumes 50 sq. in.   Eric

The Great regulator carries 6 ranks on the chest with the Open Wood = offset. The Choir regulator carries 5 ranks with no offsets.   Each divisional regulator also has its own swell engine and trem- BIIIIIGG trem!   Alas, no xylophone.   Rick

I decided to measure the actual WP of my static reservoir. It was actually running lower than I estimated, at about 3 5/8. Apparently on the original organ the reservoir came from, it had some extra weights added to the top to get it around the 4.5" it was running at. The organ was disassembled when I got it. Anyway I added some weights to get the pressure to the desired 4.5". Now the butterfly valve just barely stays in regulation with the small temporary leakage in the chamber. I suspect once I connect the rest of the system, I'll have a little too much wind bypassing the valve yet.   Thanks Al for all the great additional information. Actually, I looked at my well made Moller reservoirs last night and they all have a safety blow off valve just as Al explained. I think at this point what I will do is add one of these valves to my static reservoir. I'll adjust it so that when the organ is idling (not being played) the valve will open to just let off the small excess pressure buildup, only causing a very slight rise in Static pressure. Then when the organ is being played the valve will close and the control valve will do its thing as it should keeping the static pressure constant to the chest regulators.   As far as speed of response goes, I took one of the blank off covers off the static last night and the Spencer butterfly valve quickly opened to compensate. Also closing quickly when blanked off. The valve is somewhat bouncy though as I used nylon cord for the cable as this is what the reservoir originally used. I think with some steel or steel reenforced cable and maybe a spring instead of a weight on the end of the control arm, the loop will control plenty well enough for the static pressure.   Maybe someday I'll switch to a regulator that has built in curtain valves with enough capacity, if I run across one, but for now this is fine. Actually it looks like my larger 4x3 Moller regulator has enough capacity as it has 2 curtain valves. I want to keep these to use as chest regulators though for the chests they came with.   Thanks again for all the great advice everyone. This list is really = wonderful!   Eric

Taylor" <rtaylor@sockets.net> Date: Fri, 19 May 2000 22:33:20 -0500   Dear List,   After my initial posting, I have received several nice notes. In one = note, I was asked to share the specifications of my Aeolian Opus 1280. Below is the stoplist and explanatory notes.   Fortunately, I have copies of the original contract and numerous notes = from the former owner outlining various changes made by him. The original contract was signed August 23, 1913 with a completion date on or before September, 15, 1914. As in many Aeolian contracts, that typewritten stoplist is given in Aeolian simplified nomenclature, but customary church organ nomenclature is penciled in .   All speaking stops are at 8' unless noted otherwise.   Great Diapason (an open chest) Flute F Gross Flute Flute P Flauto Dolce Flute (high) Flute Harmonique 4' String F Viole D' Gamba String P Gemshorn Clarinet (free reed) Trumpet String PP Dulciana   Swell Diapason String F Salicional String F (vibrato) Voix Celeste, T. C. String P Viole D' Orchestre String P (Mixtu Dolce Cornet V String PP Aeoline Flute F Stopped Diapason Flute P Melodia Flute (high) Flute D' Amour 4' Flute (deep)* Gedeckt 16' (shared with Pedal) Trumpet* Oboe Vox Humana Piccolo 2'   Choir Duplexed from the Great   Pedal Flute (deep) F Bourdon 16' Flute (deep) P* Gedeckt 16' (shared with Swell) String (deep) F Violone 16' String F Cello 8'   Echo String Viole Flute Gedeckt Flute Quintadena* Quintadena Vox Humana   Harp Swell & Choir 61 notes, A-440   Chimes Great & Swell 20 notes (21st note added by Deagan w/electric = action)   * Previous owner replaced these ranks as follows:   Swell/Pedal Gedeckt 16' now Gr Gamba 8', from Rockefeller, Opus 1040 Swell Trumpet now Salicional 4' from Twombly, Opus 1428 Echo Quintadena now Salicional from Rockefeller, Opus 1040   The original Swell Trumpet was kept intact and will be reinstalled, but = the other two original ranks are gone.   The original installation instructions stated in part:   "Organ to be located in first floor hall under stairs, and in tool room in basement. Echo Organ to be located in elevator shaft above ceiling of top floor -- tone exit through stained glass window." This is Aeolian at their best!!   Bob Taylor
