I replaced the broken spring in the base of the Speedbloc and the
vibration problem has been fixed. Thanks again, JG

That was a real PIA wasn't it. LOL I took mine off and put it back on a
immediately after realizing the weight of the spring is very important in
keeping the sander balanced. I never use the clamps on the router and
thought that I could simply remove the broken/noisy pieces. If I have not
mentioned it, after the spring breaks the base usually breaks requiring the
pad assembly replacement. About $35.
