If I ground my PVC dust collection ducts to my water pipes, will I

It's a 3HP motor, but not that efficient so I'll run it on a 60A
breaker. I'm planning to get about 9,300 CFM, but will use 18-inch
duct to make sure the pressure drop isn't too bad.

I don't want SWMBO to get shocked while she's brushing her teeth.

Hope this helps,

Sounds good -- you might want to try a 60CFS motor on a 100Amp breaker
with an old 3Phase motor wired in series with an auger bit. And twirl.

Good one.

That would change the air in a garage every 20 seconds...who needs
ducting? It will BE a duct!
