My biggest concern would be accidentally damaging your fermenter if you hit the side of the vessel. If you're using a plastic bucket or Better Bottle, then even small scratches in the plastic can be sources of infection. Hitting the inside of a glass carboy with a power tool could induce "catastrophic failure." But then I'm a giant klutz and there are more coordinated people here who do this successfully.
