If I ground my PVC dust collection ducts to my water pipes, will I
need to sweat bigger copper tubing since my dust collector is 240V?

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,
John

Sounds good -- you might want to try a 60CFS motor on a 100Amp breaker=20
with an old 3Phase motor wired in series with an auger bit. And twirl.

Good one.

Here is a good read, very informative, take a look at

http://mywebpages.comcast.net/rodec/.../DC_myths.html

Read it through (it's short)

I've got to ask why you need to run a 3hp motor on a 60A ckt, is this what
you have? Sound like over kill (way over), if you use a 60A breaker (or more
like 50 is what I've seen), does the wiring support this?

9,300 CFM? Careful you don't suck up you're bench top tools. Don't know the
size impeller you're using but specs on my delta with 3hp (that's running on
a 30A ckt) is about 3000cfm. I live at 7,000 ft, so don't know what the real
value is. Vendors don't do a good job of telling us what cfm value you will
likely see.

Gee whiz, it only makes sense, doesn't it?! Seems like the greater the possible static grounding, the greater need for a good ground, hmm? Lessee, 240v, 3 horsies, 60amps, I'd say about the surface area of a good beating! Back to you, John! Tom(Who doesn't mind when she gets shocked)

9300CFM?? That would suck a sinker right off the end of my Popiel!!

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

Oh yeah! That 900 mm (~36") should be just about what you need. I
didn't see any T's or Y's on that web site though. That could be somewhat
problematic. Let's see, 9600 CFM, 36" pipe, set that in front of the
Unisaw, you don't even have to worry about offcuts riding by the blade,
they'll be sucked right into the collector. 'course if you are cutting
small pieces, you might have some problem with them being pulled in as
well. That would suck.

Well let's see, 9300 cfm through PVC will generate a static charge of
approximately 350KV, and SWMBO will probably *feel* that. So
copper tubing, any size, is out of the question. You need to replace
the copper with gold-palladium tubing for superior conductivity, and
as a bonus, the tubing looks great as it has a certain *chatoyance* to
it. Sure it costs a little more, but you don't want SWMBO shutting
down your shop, do you?

John...

I think this is a GREAT idea... wire the ducting for 220, also..

and make sure that you use #20 biscuits to hold those segmented turnings
together, also..

In answer to your next question:
Yes, you can and will paint cherry...

At this kind of power rating skip ground it to the pipes, wire the ducting
back to the DC and it will power itself.....and most of the tools in the
shop. The other advantage is that you won't have any dust within say 100
yds of the shop ( or bugs, or birds, small aircraft ......)

I was at ahouse where they had temporary power rigged up by some
amatuer. They appear to have crossed the neutral and the hot leg.
Maybe something else but when you would drink from the copper spigot
your tarter would get knocked off your teeth. A low voltage cleaning
session.
