(back) Subject: Cracked Bourdons From: "First Christian Church of Casey, IL" <kzrev@rr1.net> Date: Sun, 6 Apr 2003 23:39:13 -0500   So how did you repair the cracks? The bottom two pipes of a large 16' = Estey bourdon of mine have long cracks running down the side of the pipe. The scale is large enough that the side is not made from one board, but from two, glued together. I haven't looked closely, but I think it's a simple tongue-and-groove. I'm hoping I can put wood glue in the crack and clamp = it shut.   Dennis Steckley & A Six-Pack of Cats _______________________ Subject: RE: [Residence Organs] Overblown Boudon From: "Kelvin Smith" <KelvinSmith@UntraveledRoad.com> Date: Sun, 6 Apr 2003 21:34:03 -0600   I had some 16' bourdons which had this same problem. In looking the pipes over, I found some cracks in them. I'll never confess what happened, but the cracks were quickly and inexpensively filled and the pipes have worked beautifully ever since.      
(back) Subject: RE: [Residence Organs] Tuning From: "Carl Dodrill" <carl@dodrill.net> Date: Sun, 6 Apr 2003 22:34:04 -0700   Dear List,   I would love to hear from one or more builders on the list (or other knowledgable persons) their procedures regarding tuning. I currently identify a tuning stop in the first division, set middle C by a meter, and then turn the meter off, not using it again at all through the tuning process. I then tune within the middle C octave on the tuning stop using fourths and fifths, listening for 5 beats per 4 seconds on the fourths and = 4 beats per 5 seconds on the fifths. When the octave is essentially = perfect, I "proof" the tuning by working up into the octave immediately above, = again with fourths and fifths. Then I go from there with octaves, playing three pipes at once of the same note, only the top one of which is to be tuned. After going to the top, I then tune the tenor and bass octaves by tuning = the bottom of three notes. Having finally got the tuning stop in hand, I go = on to the other ranks and tune them against the tuning stop, in every case having the tuning stop an octave different than the stop to be tuned, and usually above the octave to be tuned. I have found this last point to be = an especially useful one, and I do not tune 8' against 8' unless I have to. Clint Meadway taught me how to do this procedure although I have yet to perfect it.   Anybody have any other ideas about tuning that produce a better result = than the above (or just as good a result with less effort)?   For Bob Taylor, I surely would bring that organ up to 440.   Carl Dodrill Pipe Organ Foundation 4488 West Mercer Way Mercer Island WA 98040 Phone: (206) 236-3492 Fax: (425) 696-0082 www.pipeorganfoundation.org carl@dodrill.net

(back) Subject: Diodes From: <Kzimmer0817@aol.com> Date: Mon, 07 Apr 2003 09:09:27 -0400   List,   I've become confused about diodes. I understand that their function is to = allow current to flow in only one direction. I think I understand the = concept of bouncing DE valves. I remember having to learn about back = torque (involving generators) and forward torque (involving motors) from = my college physics classes. The generation of a spark when the switch to = a magnet is opened is, as I understand it, due to the act of the armature = moving thru the magnetic field thereby setting up its own split second = current.   Anyway, I've heard about magnets being used to isolate magnets. I've = heard about diode use for two main functions: (1) to prevent bouncing of = the DE valves (2) to prevent sparking at the contacts I've also heard about diodes being connected in series AND in parallel. = The series part, I think I understand.

(back) Subject: (!) Pipes on eBAy; (2) "leaky' wood flues From: "F. Eugene (Gene) Dunnam" <dunnam@phys.ufl.edu> Date: Mon, 7 Apr 2003 12:29:16 -0400   Greetings, all-   (1) If you're looking for pipes, do an eBAy search under 'organ pipes'. Fellow in Illinois is parting out a mess of 'em & lists several complete ranks, already boxed in pipe trays.   (2) About 12 years ago I got hold of a Pilcher melodia rank that had been stored for 20+ years in a Florida lake house but looked to be in good shape. When 3 or 4 of the pipes wouldn't speak properly I finally traced the problem to powder post beetle damage. It's hard to believe that one hole less than 1 mm diameter can have so marked an effect! Repaired with round toothpicks and carpenter's wood glue.   Gene   ************************************************* * F.

There was something mentioned in the archives = about excess current beiong taken to ground by a diode, but I could tell = how it was hooked up.   No. What is done is that the diode is connected across the two pole of the magnet in such a way that when the current is running forward biased, the diode is simply sitting there in the circuit doing nothing. However, the generation of current when the contact is broken is called Reverse EMF and the current actually runs the opposite polarity of its normal flow. This is when the diode comes into play, in that it "shorts out" the magnet in the reverse direction only, thereby quenching the spark. > I would greatly appreciate it if somebody would fax me a schematic of = how to wire the diodes in these few situations - at the level of the = switch/relay and at the level of the magnet.

Really, no, which is what has given rise to the solid state equipment we see in most work nowadays.

My phone system at the office has one > that is much smaller, still 50 contacts though.   Mention has been made of the 110 Connectors. There are others that are used to terminate the 25 pair Amphenol connectors that were common in the old "Key" type Phone Systems. Expensive, but very useful if you plan to use those kinds of cables. We usually terminate everything in Peterson Double Row Motherboards and Krone connectors. If we're using "Angel Hair" Magnet wire, then we solder everything on Nylon "Molex" Connectors which fit the Peterson 0.156" center spacing.   Good luck! There's more connectors out there than you can shake a stick at, but the secret is to go with something low-cost and standardized, especially if you ever intend to change over to a Peterson system at some future point.   Faithfully,   G.A. -- Richard Schneider, PRES/CEO SCHNEIDER PIPE ORGANS, Inc.
