4" vs 6" ducting for effective dust collecting
I'm reading "Bill's Place" (Bill Pentz) and his writeups on what does or
doesn't constitute an effective dust collection system. He insists that 4" ducting is woefully inadequate for safe dust collection. He writes that 6" is what is needed. His writeup gets fairly technical and sounds very convincing. But of course, using 6" ducting greatly increases the cost of the ducting for my workshop. Are there other opinions on this or do people pretty much agree that 4" ducting is inadequate? Jack |
4" vs 6" ducting for effective dust collecting
I converted from 4" to 6" after reading Bill's site. The flow is much
better, though I will need to convert to a cyclone in the near future. To me, cost is irrelevant. We spend $1000's of dollars on our tools to make this dust, that if we don't collect right at the source as soon as it is generated, will end up in our lungs causing us untold health problems. I say, spend a $1000 or so, forgo the upgrade on that tablesaw or jointer, and ensure that we can continue woodworking for years to come.

4" vs 6" ducting for effective dust collecting
I've spent a lot of time at Bill's Place too. The only question in my
mind is whether the nexus between occasional exposure to wood dust and lung problems has been adequately established by the medical community. I'm not arguing against it, I'm just not yet fully convinced. I haven't done any controlled experiments like he did, but as an engineer, I find no fault with his statements about what is necessary to capture that fine dust that causes so much concern. I totally agree that it's easy enough to collect the chips that you'd be sweeping off the floor, but it requires much more air flow AT THE TOOL to capture all the micro-particles. To move that much air, you need big blowers and big pipes. DonkeyHody "Every man is my superior in that I can learn from him." - Thomas Carlyle |

4" vs 6" ducting for effective dust collecting
My workshop seems painfully small to accomodate a 6" ducting system. I
expect most of my work to be routing and scroll sawing and hence don't think the dust problem will justify the expense of a 6" system. Of course, it's dangerous to put a price on one's health. Lung problems caused by inhalation of microfine particles is pretty nasty (so I've heard).

Some people have had allergic reactions to wood dust and no longer can
work wood. These reactions can come about after prolonged exposure, with no obvious ill effects to breathing the dust, and all of a sudden they either must wear a respirator or not work wood. If you have this genetic trigger, it can happen right out of the blue with little or no warning. 4" pipe CAN work for some machines with a large enough blower. It depends on a lot of factors. Its just for most machines and blowers, the 6" pipe is required. mywebaccts (at) PLUGcomcast.net wrote: My workshop seems painfully small to accomodate a 6" ducting system.

The article on Bill's site tries to explain why and when to choose a particular size. You can't ignore the physics behind what's going on without reducing efficiency. Look at the velocity needed to keep the dust suspended in the airstream. If you don't have that velocity, the dust will settle out in the pipe. Velocity is a function of CFM and pipe cross-section. FOr a given CFM, making the pipe larger (larger cross section) will result in lower velocity. At some point, you end up with a situation where the dust never makes it to the blower. In vertical runs, gravity is working to reduce velocity as well. So you might need a smaller pipe in vertical runs to keep the dust moving. Too small a pipe, on the other hand, introduces a lot of frictional loss, so the velocity will drop. The result is the same; the dust does not move through the system. For a small shop, it is probably not necessary to go through a bunch of precise computations. Rule of thumb ar a good thing. I used one in designing my DC system, and its worked very well for me. I think I found this on Bill's site, but I don't remember so well, and I'm not looking at that right now. But it said that, for a 2HP/1200CFM blower, 6 inch pipe is about right for horizontal runs, but a bit too big for vertical runs. So I used 6 inch pipe everywhere, except for the drops to my machines, where I used 4 inch pipe. I built my system using S&D PVC, and used 45 degree bends exclusively (2 in a row where I needed a 90 degree bend) and 45 degree Ys for take-offs. -- Art |

Bob:
As far as your father is concerned, a number of factors are in play here. Perhaps he did not a predisposition to an allergy or lung problem. Lung problems run in my family. Another point is in the past there was a lot less sanding done, especially by machine. They tended to plane and scrape much more so the shop environment was healthier. As far spending the money goes, everyone makes that decision for themselves as to their priorities in life. Its a personal choice to gamble that it won't happen to you. Another factor, Bob, is the shop itself. If your shop is open to the air, then air quality is less of a concern. These bags collectors with small 4" pipe are dust pumps, pure and simple. When you watch them inflate with sunlight in back of them, you can see the cloud of dust produced. As far as I'm concerned, you need a large blower with 6" pipe and very good (.5 micron - certified) filtration.

Chris:
I hear what you're saying. I understand though from Bill's site that some studies have indicated that the typical hobbiest woodworker has more exposure than large industrial settings because the size of the particles involved are smaller in a hobby situation than in an industrial one. With the large industrial settings the bag house is located outside and therefore no threat to air quality at all, whereas in a small shop the air is recirculated.

I bet he won't ever come back to check for replies. Bill Pentz was a woodworker who got hit with dust causing health problems and advocates a big cyclone to collect as much fine dust as possible as well as PPE. I have one but never got the pipe to hook it up. (Btw, I'm shifting to more of a "driveway woodshop" style due to a move. Anyone interested in a tested but never used Clearvue Cyclone?) I followed Bill's advice--the most powerful tool in my shop is the cyclone. In all honesty, for my use it's gross overkill--I suspect one from Woodcraft would be perfectly adequate. One thing about the big one though, it doesn't produce that "need hearing protection scream" that some do--more of a low rumble. |

Is a big giant cyclone with hard to find (for me at least) 6" PVC pipe still the awesomest way to go? Is a broom still the best way to remove sawdust from the floor, especially when we can buy a Festool tool to do that? Puckdropper (Questions 1 and 2 are serious.) He's found out that trolling works. All of these posts from homoaners club are from the same person. Well the guy did post under the name of Bill Pentz... and referred people to his blog without linking it. I bet he won't ever come back to check for replies. Check the headers. The "Hermes 2.0" tag has shown up in every one of the antediluvian posts Homemoaner Club articles. They're all trolling from same person. Bill Pentz was a woodworker who got hit with dust causing health problems and advocates a big cyclone to collect as much fine dust as possible as well as PPE. I have one but never got the pipe to hook it up. (Btw, I'm shifting to more of a "driveway woodshop" style due to a move. Anyone interested in a tested but never used Clearvue Cyclone?) I'm going the other way. I'm working on the finance committed to justify a HEPA dust collector. |
