The noise from the vacuum is the thing has stopped me. I have a dust collection set up for my other machines, which I only use when the machines are being used and then with earmuffs. I had a "Shop"vac once, it sounded like a B52 taking off, mind you it would suck paint of a wall.
Hearing protection is so very important, I suffer from industrial deafness, from my time as cabinetmaker working in workshops with huge thicknessers, shapers etc. Well before any regulations.
