I'd have some concern about the heat rise of its motor if it was that confined. One 3 button run is about 13-17 minutes of runtime with the limited feed speeds, although I've found the 1/16" mill, plowing 10 to 12 thou deep, can be safely moved at 18 ipm IF the vacuum is keeping the cutout groove its making clean. As for hooking the outlet to a couple of 90 sweeps and sticking it back into a bucket full of foam, I don't think there is room on the floor for the 3rd bucket. But I have an oval wire basket from a defunct paper shredder that might fit, as would one of those yellow plastic 2 gallon trash cans. I'll check that out tomorrow, er, ah later today. I was surprised to see they sell a plastic muffler for about $13, but its only a 5 db reduction, and it could stand to be 15 to 20 to adequately quiet it. A 7/16" OSB box, sized to fit the space, and stuffed full of open cell foam might work. IIRC theres a small roll of rug under-layment in the basement that might be just the ticket except its closed cell. Or I could live with it, I've only about 40 or 50 more buttons to make. But the vacuum use has made it possible to speed things up from 4 ipm and a blast from an air hose about 2x a pass over the loop to clean out the groove, to 18 ipm with the vacuum running, so its definitely worth it.
