Ambiguity in the title because I'm not sure which it technically is
I bought a small folding reed organ to have a go at restoring. It has its own built-in workbench, which is handy. It took me half a day but I've figured out how it disassembles. Bit of a challenge in places; the front panel was a particular bitch thanks to it being a poorly-fitting replacement that someone had nailed in place (if only I could go back in time and uninvent nails).
The reeds all seem in good nick and it's remarkably in tune, at A=455hz. Not sure I'll change that, as it sounds rather nice. The big problem is the bellows system, however, which is very leaky.
They look to be a rubberised canvas sorta material, and I suspect they need replacing. I assume they're glued on, and need cutting to remove? I'd probably replace them with leather, if possible, as it shouldn't wear in the folds quite as much. Might have to be quite thin though I suspect.
It does play at the moment, but AFAIK it's supposed to work using a vacuum in the air reservoir, which uh, doesn't work when there's so many holes in it
Anyone had a go at restoring one of these before? Got any tips?
