Wurly 200 reed assembly
« on: May 06, 2015, 11:24:45 AM »
Just out of curiousity I was wondering if anyone could shed some light on the fact that the reed assembly (the big metal part where the reeds are mounted in) is pretty different in mass when you compare the left side to the right one?

I have wondered the same thing until I came across a 112 and looked inside. If you look at this picture of this 112 reedbar currently for sale on eBay, you'll see a large block of steel bolted to the reedbar. Mine had a thin piece of brass shimstock between the steel block and the reed screws (I assume for full contact across all of them?).  When I removed this block and played a few notes, they were very dull sounding and short-lived. Reinstalling the block and shim brought these reeds back to life. It was as if the reedbar casting was too thin and wimpy in this upper section. Adding mass must improve resonance I assume? The upper reedbar of the 140/200 series is indeed much more massive and maybe this is why. This makes me think of the old Hurdy Gurdy hand-crank tiny music boxes. Winding them in open air and they sound soft and wimpy, but placing them on a wall and they can fill the room.

Thanks for the input. You may very well be right about the added mass adding to sustain in this section... I've thought this could be the reason but wasn't sure. Others who would add their thoughts on this?
