Thanks Rich, Now, as far as the motor assembly's relationship to the bedplate, this Model A uses the three sets of upper and lower springs rather than rubber washers which are solely used between the top works and bedplate. Any reason to supplement the springs with rubber washers as well (although I don't think the 3 screws are long enough to accommodate anything other than the upper and lower springs.)? Thanks for the heads up on Sorbothane.
