Thanks all for your information and instructions for the C Spring seismomet=
er. I cheated on the boom and used 3/4 in. 1/16 in. aluminum stock with rei=
nforcing ridges on two sides from my scrap box that weighs 9.7 oz. I'll tr=
y to find some 1/2" stock=2C and also try the other remedies suggested.
Thanks again.
