(back) Subject: RE: [Residence Organs] Spencer From: "L.Huivenaar" <> Date: Wed, 18 Jul 2001 23:24:19 +0200   Hello Wurlic and Larry,   Thank you very much . This is very useful information. Not every part of this Spencer is still there. So, we have to choose for an more modern windblower with a capacity of at least 18,7 cubic mtr and 5-7 inch pressure or restoring the old Spencer, which I prefer ofcourse. The Estey #2088 Residence Player Pipe organ from 1923 restoration is already a 1/3 ready. The Console and the orchestrator are completely done. It took 8 months to restore. Waterdamage is a killer.   Thanks, Louis Huivenaar Netherlands   -----Oorspronkelijk bericht----- Van: []Namens = Larry Chace Verzonden: woensdag 18 juli 2001 5:28 Aan: Residence Organ List Onderwerp: Re: [Residence Organs] Spencer   Louis Huivenaar <> asked about the wind flow rating for a 1HP Spencer Orgoblo. I have an old Organ Supply catalog from 1978 that has specifications for various Orgoblos. For two-stage units, at 1150rpm or 1750rpm, 1HP is shown to deliver 660 cubic feet per minute at = 5" pressure. (That is to say, the actual static pressure will be somewhat higher, perhaps 7", so that you could expect to actually voice the = pipework on 5". Such was Spencer's way of describing their machines.)   A quick attempt at conversion suggests that 660cfm is 18.7 cubic meters = per minute. I'd guess that there are great similarities between the 1921 and 1978 units! If anything, perhaps, the 1921 "horses" might have been a bit more powerful!   Larry Chace             DIYAPASON-L: a Discussion list for owners and builders of their own Residence Pipe Organs.
