I'd be grateful if he/she (or anyone else) would get in touch with me to let me know what conclusions were arrived at.   I am planning (still planning!) to install an organ of perhaps 35 ranks = over three manuals.

So, the valves were barely working, I guess. And, barely closing, as evidenced by the wheezing and groaning when the blower came on. I finally figured out that the pouch springs must have been carefully = selected by the original builder to have very light pressure so that 2.75" would = open them. But the residual pressure against the bottom of the toe board was = so light the valve would barely seal, hence the leakage.   What worked...   There were two different DVA diameters. I jigged up for it with two adjustable clamps, one that held the DVA body in place, the other that pressed the new leather pouch/valve against the spring, depressing it = enough to take the tension off and allow the liquid hide glue to set. The jig worked OK. A few pouches ended up slightly off center but were still workable.   What didn't work...   I ordered the pouch leather/valves from OSI along with the lightest = springs they had. I had to cut the springs in half and did the releathering with the jig I described above, but the residual pressure was too much for = 2.75" and the DVA's wouldn't open. Quite a waste of money!   In retrospect...   I took one DVA that actually did work, along with 72 direct electric = valves, and installed them in the chest and that's been working ever since. A friend works for a local organ builder and mentioned that he builder = doesn't really like DVA's in general. For low wind pressure he typically installs direct electric valves, and for anything else he builds his own pouch = valve assemblies.   I believe that OSI charges something like $8 per valve at present to releather. It doesn't seem a whole lot less than the price of a new one. In our case, new or rebuilt would still have been operated below specified minimum pressure and would not have been an option in our particular case.   And, Richard Schneider said, "The ONLY Suggestion is to let OSI, who now owns the Reisner dies, re-cover them for you. They have the correct jigs and techniques. Any attempt on a DIY will fail miserably. Take it from someone who knows!" That's probably the best wisdom.   Jon Fick Christ Memorial Church Williston, Vermont       Subject: Re-leathering Reisner DVAs From: "Richard Schneider" <arpschneider@starband.net> Date: Mon, 04 Nov 2002 20:44:01 -0600   Olliff Weldon wrote:   > I have a number of DVAs I want to releather.

I am wondering whether simply to reduce the depth, which, as you say, would clearly be superfluous, or whether to embark on a more ambitious minitiaturization.   Regards, . . .

To me, the conclusion reached was that there are certain obvious limitations to reducing the size of = consoles (the pedalboard being foremost among them). If you are going to have a 35-rank instrument, you'll need a decent amount of real estate for = drawknobs too.   Drawknobs on side jambs are a big problem. If a console used tilt-tabs or the like, they could be arranged above the top manual, thus making it possible to decrease the width of the console. I just happen to really = like drawknobs! And still, there is the pedalboard down below, which will = become the limiting factor if side jambs are reduced/eliminated. Holtkamp has built many consoles without jambs, and although they have the same (or almost) footprint as traditional consoles, they seem less imposing because of their less substantial upper portions.   One thing is that consoles do not have to be deep. They can end just = behind the keys - there's no need for 2' or more of mass behind the keys. = Without old-fashioned combination actions and/or pneumatic consoles, the only mechanism that needs to fit in there is a simple contact on each key.   It's an interesting question, especially for us guys trying to stuff these things into our homes. And I agree with you - I'd much rather dedicate space to pipes. But there's only so much we can do.   Some people replied to my questions with diagrams, pictures, etc. I can forward them along to you if you'd like.   -Jon   -----Original Message----- From: Alwyn V.

Depend on some hard =   objects to break up the slap but to keep the room alive. My room at this point has no padded furnishings or carpet except for two small padded chairs. The organ sounds better than ever now with the sound continuing = for a short period after the keys are let up. The lack of furniture is due to = a divorce. Once I get remarried who knows how the organ will end up = sounding, or if I even have one. Guess I need to look for the right kind of wife.   Eric
