I used a set of wire-mesh mounts on a crappy old washing machine that shook and vibrated like heck, in a manufactured home we lived in. Dampened things down pretty good. Bought them at Boeing Surplus, so you may check around at industrial supply houses in your area.
Some 20 years ago I worked for a guy that had a machine shop in his garage(it was a BIG garage), and all our machines ran off 2 converters that were mounted on the wall. Yeah, nothing like that 60cps drone on a wood frame building!
