    So I need to remove all those screws and the foundation board, before I lift up the bellows board and bellows?
    Every layer you take out reveals the next set of screws, but you're just about to the end.

      Thanks Casey. You're right - there's not much left to remove!

      All the reeds are in that foundation board. The "reed holders" are glued in - not screwed.

      Even after removing the foundation board, the reeds are still covered and inaccessible, other than by prying up the damper (?) bars that cover them.



      How to I access (or remove) the reeds to clean them?

        The foundation is *out*! I removed the 16 screws around the edge, and the six large inset screws, then carefully lifted out the foundation about an inch then slid it toward the rear. Nothing so far has crumbled or fallen apart.

        To me it's amazing how "clean and new" the underside of the foundation looks.

        Tomorrow my neighbor will help me lift the bellows assembly out. I'll probably start a new thread on the reservoir restoration and reed cleaning, unless it's better to stay with this thread.

        Thanks.

          I would keep this thread going.
          You need a reed puller to gently withdraw the reeds from the reed cells, being absolutely careful to not mix them up. I put them on separate small trays, whatever reeds are under a particular mute (what you called a damper) constitute a set.
          And I notice there is a new topic about reed pullers.

            Tom,

            This thread is great! You're the first person to pictorially demonstrate the entire process of disassembly I recall seeing on the Forum. THANK YOU!!!

            If you have a reed puller, gently lift the damper/mute board just enough to access the reeds. The hook at the end of the reed puller will fit nicely into the void at the end of each reed, and you can pull/slide them directly outward. If you do not have a reed puller, I've heard of people using a crochet hook, but I can't vouch for that method because I've never personally tried it.

            Tom,

            Ultimately it's your choice, but if at all possible, please do not start a new thread. If this thread continues in the direction you've started it, I can see it being made a sticky thread for anyone else to refer to when repairing their own organ. Feel free to keep adding to this thread. I can change the title of the thread to reflect the entire content of the thread when you get to the end.

            You're doing great work so far. Thank you for sharing it with us.

              Thanks again gents. I'll keep this thread going.

              So I take it that removing *all* the reeds (and keeping them in order) is the way to go? Clean the reeds, and clean all around the "reed bed" on the foundation?

                Yes. A brush and vacuum should spruce up the felt (or whatever that gray material is) under the reed heels. A full rehab will need to include wet-cleaning the reeds. I can't stress enough how important it is to keep them in order and not mingle the sets. A lot of people have been using ultrasonic baths for reeds with great results. I use a bit of cleaner and a toothbrush to scrub them. You may scrub sideways across the rivet end, but always brush away from the tip at the free end.
                Us a light to look inside the reed cells for debris and insect cocoons.

                  The reservoir is *out*!

                  I leaned the organ backward a bit so I could reach up underneath and remove the screws holding the treadle straps.

                  Then neighbor and I lifted up the reservoir, set it on a stand to inspect how it's made, then decided to invert it so I could access the reservoir itself.

                  Lots of cracks, but that "white point" isn't a tear, it's just where the material flexes.

                  Looks like lots of leather and rubber fabric needs replacing.

                  Please comment on what else you notice, so I can order parts and materials.

                  Thanks!

                    Expand one of the feeders (the pumping bellows) open and show what the side of it looks like.
                    The reservoir rubber cloth is very crunchy looking.

                      Casey - both feeders look similar. The gap goes pretty much from top to bottom.

                      Hide glue should arrive Friday or Saturday. But I don't know what materials to order for the repairs.

                        You need some leather to rebuild the pumpers.

                          Nice going. The cloth on the bellows and feeders is really kaput. Since you have committed to go the whole hog might as well do everything. That is a nice looking cabinet and certainly worth doing up well.

                          Thanks for keeping us updated.

                            Gentlemen - can you point me to details on how to remove the bellows/feeders?

                            I've removed six long wood screws that run down from the bellows board into the top of the bellows. But the bellows is still tight on the board. Here's the junction, the thin light brown "seal" which runs along all four edges of the bellows/bellows board.

                            Is that seal wood? or glue? or leather? and how to disconnect bellows from board?

                            thanks.

                              It's glued. Separating it requires a very light touch with a sledgehammer.
                              Two things will loosen the glue, heat and water. But they are indiscriminate; every other glued joint in the vicinity may be loosened too.
                              If the joint has been poorly made, it could pop right apart with a chisel or small prybar from one or both ends. More often than not, the wood splits.
                              You can saw the glue line with a Japanese-style pull-saw.
                              Once the two parts are separated, and the wood is irreparably damaged, it's best to have the woodworking skills to replace a section of the lower foundation, and/or the top part of the reservoir wood.

                                As Casey says - "Irreparably damaged". Yep, that's the description. Disaster.

                                After using three different woodsaws, including a "kerf saw", none of which would cut into the glue joint, I tried hot water - dripping it along the joint once every ten minutes for several hours. Saws still didn't cut into the joint, so I tried a steel chisel, tapping it gradually deeper into the joint after every hot water application. As I didn't know how thick that wood is, or what was "inside", I guesstimated a one inch depth, and tapped the chisel in about 1.5" total, going about 1/8" at a time. After cutting through the three outward facing sides, I began prying upwards with the chisel.

                                Crack. The bellows board (lower layer) split in two places.

                                Now figuring I'd ruined the whole unit, I completed chiseling, then lifting slowly with a small flat end pry bar, all around those three edges, until the bellows unit seemed free.

                                Lifted it up and found I'd completely wrecked the (1) top of the bellows,

                                and (2) the bottom of the bellows board where the union is.

                                Chips and chunks pulled loose all over those two surfaces. I'm no carpenter; maybe I can just glue it all back together after repairing the bellows unit? Before I completely give up in despair, I'd appreciate some advice, and reassuring words of condolence.
