  • George Wood - after removing the stop rail

    In Tyler's guide to restoration on ROS, he writes:

    You want next to take out the "upper action" in its entirety. This is the shallow box on which everything you have exposed sits. There are usually long screws along the back and sides; the ones in front may be driven from the top, or up from below, and the ones along the sides are often difficult to find and reach. Once all the screws are found, removed and labeled, lift the upper action up (there are usually small locating pins somewhere) until it's completely free, and carefully extract it from the case (some actions must go out the back of the case, some only out the front, and only you can determine which yours requires!) Once the action is free and out of the case, set it aside, once again being careful not to damage the parts underneath. (Prop it up on chunks of wood if there are too many things protruding below).

    What is the "upper action"? After removing the stop rail and attaching arms, I see the full keyboard. Only other things are those boxes at the rear of the instrument. What should be my next step?

    remove the keyboard frame, sub bass chest, solo chest; the upper action is what the sub bass,etc., screws into. There will be screws every 6" or so around the perimeter, usually round-headed.

      Tom,

      Unless I miss my guess, at least one of those boxes at the rear are the sub bass reeds. You'll find holes under them for the wind supply. The action generally refers to the keyboard and its frame.

        I looked at the bottom of each box, and was surprised how clean and "new" each looked. The red felt look perfect. There's an air passage on the right side also.

        When you say remove the keyboard frame, do I just remove the screws holding the four vertical brackets? (three in front of keyboard, one behind.) Here's the one under the top C:

        And then the keyboard will just lift out?

        This is all new to me, so my natural paranoia of not knowing what to watch out for makes me take it slow and steady.

        Thanks.

          When you finally get to removing the wind chest (That is the shallow upper part above the bellows) You will need to replace the seal that is on the underside right around the perimeter. This seal prevents air leaking out when the organ is playing. Replace this seal - do not try to bypass this step - if you don't, you will have to do the entire job all over again - I have tried and had to do this. Soft leather strips about 1/16" thick and about 7/8" wide will do the trick. If the bellows cloth is torn, brittle or cracked, the only way is to replace the entire bellows cloth - and while you are about it, do the feeders as well.

          It is also easier to get at the reeds and all other action components while the parts are out of the cabinet. Just be sure to mark each part in such a way that you replace it in its original position - even the screws!

          Nice going, and by the way, you need not start a new thread for each conversation, just continue from where you left off. Post pictures and ask questions, do not be afraid that you will be critisized or whatever. I have asked many questioned that I considered to be dumb ones, and maybe they were, but that is the way I learned from the friendly and helpful gurus on this Forum family.

            Nico - thanks for the words of wisdom. Have to admit learning the terminology is a challenge. Wind chest? Reservoir? Exhauster? Keyboard frame? Wish there were a diagram showing all the systems and subsystems, with a label on each!

            Say, can you advise me on removing the keyboard? If I remove those four vertical brackets (three on front, one on rear), is that all I need to do to pull/lift that keyboard out?

            Thanks.
            Tom M.
            PS - here's the "signature" on the back of the keyboard. "T. Campbell July 27 1874". I have no idea what that long wood screw is for.

              That signature speaks a thousand words. It could be the original assembly completion date or the date of some kind of service or repair. It was common in those days to sign the work in pencil, sometimes a rubber stamp was added. The screw looks like a stop of some kind.

              Send me a PM and I will mail you a file that might help with terminology and more.

              Take care

                  Keyboard is out! Had to disconnect a few assorted levers and extra supports, but nothing fell to the floor or exploded and flew across the room. (Note that as I remove parts, I put every screw back in place after removal, so they're ready to go when I start to re-assemble.)

                  Tyler says that after removing the keyboard, remove the coupler(s). There are none. Then he says to remove the "stickers". Are these the short vertical wooden dowels, one for each note?

                  After removing the stickers (and keeping them in order), he says to remove the swell action. Is the swell action that knee bar that opens a flap under the keyboard?

                  Thanks for your guidance and patience!

                    Tom,

                    Yes, and Yes. Make sure you remember where everything was. A handy trick for keeping the "stickers" in order is to use a long piece of tape (that doesn't leave a residue) and place them on the tape in order and coil it up.

                      I DO hope you are taking a lot of detail pictures for documentation, including writing in a notebook what each picture entails. All those crazy linkages you're seeing are specific to the organ manufacturer and may wrap around and under each other. There won't be much help here putting it back together if you have tangled piles of parts.

                      I use small freezer bags to put little parts in, like a row of screws. Then magic marker the contents on the bag.

                      "Swell" can refer to the right-hand lever and the associated mechanism, including the long covers over the reeds and the linkages that make it work. It can also link in to "forte" stops on the stop board.

                        Removed four screws and lifted the "swell" system. Note that the rear-facing flap wasn't connected to the system; the hinge tape had ripped.

                        Here's what was under the swell system. I have no idea what I'm looking at.

                        There are four spring-actuated flaps, two in front, two in rear. Lifting the flaps I think I see the brass reeds. Also, I don't know the purpose of those rectangular "flaps" at the treble end.

                        According to Tyler, after removing the swell, I should see the "foundation". But he doesn't mention all those reeds that I see there now.

                          Tuesday morning - I figured out how to remove the foundation. At least, I hope it's called the foundation.

                          I removed the four large, recessed wood screws at the sides of the thick wooden block/table which contains the reeds and sits inside the cabinet.

                          When I lift that block, the big bellows/reservoir lifts up too. Looks like it's all one unit.

                          The two wooden action supports at each side of the foundation are glued on, so they're staying in place. When I pull up that big foundation and reservoir, can I lay it on its back?

                          Before removing the foundation/bellows, I need to remove the two springs (seems easy enough to do). But I don't know how to handle those wooden arms just behind the springs. Do they remain attached to the foundation/bellows while removing it?

                          The left treadle still has its tape attached to the bellows. With the bellows in place, how do I disconnect the tape to allow removal of the bellows? (The right treadle tape was off the bellows when I got the instrument.) There's no space to stretch my arm up to the top where the tape is attached - unless the bellows has been removed.

                          PS - sure seems it would have been beneficial to make the lower front panel removable from the front!

                            Great job! You are down to the foundation, that is correct. It is screwed down to the bellows board (the bottom of the windchest; the foundation board is the top half of the windchest) with up to two dozen screws, some may be accessed from beneath. The upper action/foundation will then lift out. You will then see clearly how the reservoir is attached to the lower windchest board, and how that component itself attaches to the case.

                            Those little rectangles at the treble ends of the "mutes" (the spring-mounted strips covering the reeds) should be left alone if possible. (if it ain't broke...) they are a very delicate and precarious system for making sure the tiny reeds stay silent when they are supposed to be silent. A tiny felt-tipped dowel is lowered to touch the reeds when the stop if off. There is nothing to be gained by disturbing them at this point. It is likely down the road that you will need to replace the soft leather facing on these mutes so that the stops turn off when closed. At that point we'll figure out how to safely get these devices out of your way.

                              OK - thank you!

                              So I need to remove all those screws and the foundation board, before I lift up the bellows board and bellows?
