(Standard recording studio technique). if you don't want to go that far, the more mass the better. Probably more important is to fit a seal all round, so there's no gaps for sound to leak through!   Every Blessing   Tony ----- Original Message ----- From: "Robert Eversman" <> To: "Residence Organ List" <> Sent: Wednesday, July 24, 2002 8:12 PM Subject: [Residence Organs] swell box door     | Hi all, | | I am soon to have a swell box built in my basement.

That is because a different approach is being taken to my organ project. Formally, I had planned a "repair and install". Now, it has become "fully restore and install".   That means I am confronted with over 2,500 pouches to reinstall for just the pipe pallet valves. These pouches range in size from about 1 3/4 inches to 3 1/2 inches. I am an experienced player piano rebuilder, and have installed thousands of pouches, in vacuum systems. I know how to get the perfect dip into the pouch well on those systems. But on this organ, the existing pouches have an excess amount of dip--more than what the = pouch well will hold. In other words, the inflated pouch extends above the = pouch board far beyond the depth of the well.   How are these pouches installed with that much dip? How is the dip made uniformly? Could this excess amount that I have observed be due to = stretch in the pouch leather after it was installed?   I would love to hear your comments, as usual. For those who don't know, this is a very serious effort with full shop facilities. Suggestions could be made accordingly, eventhough the folksy stuff sometimes works the best.   Restoring Aeolian Opus 1280, 3M/34R 38 stop player organ, Bob Taylor, Columbia, MO.
