Sound proofing / deadening
Pb SOUND DAMPING
Kevin/Phil,
I don't know much about sound deadening - however, the floating
lead sheet idea sounds good. Watch out for corrosion between lead and
aluminium - as you recall, you can unwittingly generate a redox reaction
between these two dissimilar metals. Fishermen know all about this
phenomenon and the long term result of lost lead sinkers in the depths of
their aluminium dinghies! I guess a non conducting barrier between the
metals would negate the problem. Do the 411s have steel tanks?
Regards,
Brett
