Larger copper pipes for dust collection?
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 |
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. wrote in message . ..

Hope this helps, John 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. 9300CFM?? That would suck a sinker right off the end of my Popiel!! |

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

Just use a little Sting-eze, they're barbless hooks.

Hope this helps, John 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? |

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..

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.
