Gee, I would think that unless your're going to cut at 2am and your garage wall ajoins your neighbors bedroom, you'd be ok with small laminate router or dremel setup. I'd equate it to the level of noise your blender makes when you whip a batch of margaritas, but without the crunching hopefully. Actually, your best bet is to show it to your neighbor right off, and while he's checkin it out, cut him a address or name sign out of a inexpensive piece of cedar fence plank. Then, when he hears the machine he'll come runnin to see what you're makin!
