Andrew,
    Get mine from a machine shop. 1 1/2" brass rod, cut to various lengths 
from about 3/4 of an inch up to 1 1/4 long. It's worth whatever he's 
charging me for him to cut it, y'know. His rates are lower than mine.........

Later,
Guy

I'm finally getting around to working on the piano which had a boomy 
crossover from the long bridge to the bass bridge.  I'm envisioning getting 
some rolled brass stock and cutting off pieces for this.  I've cut aluminum 
with a carbide blade, I think brass might be a little harder.  How 
difficult is this to do?  I'd drill a screw hole in the center and 
temporarily set under the bridge until I get the impedance I want.
