MusingMuso Posted April 7, 2013 Share Posted April 7, 2013 I can scarcely believe the problems we are having with what should be a very straightforward and normally very reliable mechanical action. Great minds sometimes think alike, and when the organ tuner pondered the possibility of an earthquake, exactly the same thought had crossed my mind.....the action is all over the place; quite literally. The symptoms include the following:- Pedal notes cyphering when the 16ft Bordun is drawn The Brustwerk keys resembling a roller-coaster visually, and some so far down, the notes will not speak properly, with many notes not coupling through properly. The problems began in late February with the pedal 16ft, which required me to back off the adjustment of the leather buttons at the pedal board.....that worked, but other notes soon followed. I then made the mistake of re-tuning the Brustwerk while coupled to the Hauptwerk; not realising that the action was not working correctly. The end result within a couple of days was horrific, and required a full re-tune by electronic means. I think I now realise what the problem is. The church is generously heated most days, and seldom falls below 50F even in the coldest weather. Add to this the incredibly dry winds we have had from the east, combined with the extreme cold of the air, and I suspect that the wooden action components have shrunk; tightening up the action and causing the cyphers and uneven keys. It really has to be seen to be believed.....some keys are half an inch lower than others. My question is this:- Have any organ-builders/organists/tuners ever experienced anything like this, and particularly in the past month or two? My hope is that when the rain and south westerly winds return, things may self correct. If not, it's going to be a big job to re-adjust almost every note on the organ, and even then, the adjustments may go "walkabout" unless the wood has returned to normal levels of moisture content. Having known this organ for 38 years, I've never known anything like it in all that time. On Sunday morning, the organ was almost unplayable, but we managed to make a few acceptable squeaks.
