I’ve actually considered putting the entire machine into an enclosure with space for the vacuum underneath, but I live in a townhouse and my garage shares walls with two neighbor’s living spaces. I really don’t want to be a noise nuisance to my neighbors.
Another thing I’ve considered is building a sturdier table/base/stand for the machine using a loudspeaker stand building technique. Basically you use large diameter PVC pipe for the legs and fill them with sand (plywood above and below the tubes and all-thread through the middle to hold it all together).
Probably all a bit excessive, but interesting to consider!
