This was great. I'd a thought a man of your caliber would have QC pipe through out your shop. But you saved a ton of money and did a fantastic job. Thanks.

@BlakePizzey Год назад

Hi Jonathan - great video! A couple comments from an HVAC Engineer who designs DC systems. Great info but around 2:00 you mention that you should run as large as pipe as you can... Not always true and it can be unsafe to run too large of pipe. Pipe should be sized to keep ~4000 FPM (air speed) in your lines and if your pipe is too large your speed will drop below this. I have a video that teaches how to calculate this. Also, I recommend running that 6" line of yours right to the tool. Flip your flex hose from 4" to 6" and you will see a huge difference. That 4" flex line introduces the same amount of static as your entire 6" run. Love your channel and thanks for everything!

@scottmiskin4858 Год назад

Should you put a blast gate at the start of each branch of the system to shut it off as close to the main line as possible or will that make any difference as long as the blast gate is shut off at the end of the unused line?

@travisgray9421 Год назад

Fellow HVAC engineer, can confirm everything above. ASHRAE recommends upwards of 4,500 fpm for heavier/larger chunks. Larger ductwork will provide more air volume (CFM), but at a lower air velocity the particulates (dust) will fall out of the airstream and eventually clog up inside of the ductwork.

@travisgray9421 Год назад

@@scottmiskin4858 From strictly an HVAC perspective, keeping it as close to the main would be preferred, as any leaks in your ductwork between the main and the tool are taken out of the equation. If you have the blast gate all the way at the tool, the entire run is under negative pressure and the leaks in that branch will still add to the system. From a woodworker's perspective, seal up your ductwork as best as possible (as JKM did) and then put the blast gate where is it most convenient so you make sure to open/close them appropriately. It's not worth it to get a ladder to have to close the blast gate just to save a few CFM worth of leaks.

@bobd. Год назад

Good tips, thanks. A suggestion for anyone with a small relatively square shop that plans to put their dust collector in the corner. Don't stick to running everything N/S and E/W or perpendicular to the walls. Plan out your tool placement then draw a floor plan looking down on all your tools and where their dust ports are located. If you're planning to run across the ceiling think about going diagonally out of the corner with your main line. Then all your branches are 45s off the main, just locate the Wye in the correct spot so your branch line runs over to the drop point above the tool. You can save some fittings and reduce suction loss with this method.

I skipped PVC and went straight to metal ducting from The Blast Gate Co. Wish I would have spent a little more on the Nordfab style with the quick clamps. When I did mine 8 months ago, the metal ducting was actually cheaper and WAY easier to source than PVC. Plus, I was able to ground the ducting to my DC and then to a ground in the outlet so the system itself is all grounded. 3HP Oneida V3000. Also, The Blast Gate Co. metal gats are fantastic, I've never had an issue with them getting clogged or bent. I've spent a LOT of money and time on DC, starting with a shop vac and then 2.5" hose, and the 4" flex hose, and then finally a proper system. If you're serious about it, save your time and frustration - go straight to a 3-5HP system and metal ducting. It's SOOOO much more efficient and better.

@alanr745 Год назад

PVC is smoother than metal ducting. This has been scientifically proven, but to your point, I’d bet my next paycheck that the transitions and joints are smoother with NordFab than with PVC, all other things equal.

@daryncashmark6518 Год назад

Two more advantages of the Nordfab style: 1) I have moved my shop twice and was able to very easily disassemble and reuse all of the components. My current shop is the biggest dust collection system so far so I had to add components, but it was still very easy. 2) if you ever move and end up with parts that you can no longer use, or just give up and sell everything 🤯 the metal duct components can actually be sold and retain a surprising amount of their original value if not damaged.

Industrial hygiene practitioner here - larger diameter pipes can be good, but not always. It depends on the specifications of your fan. Different tools might require different air velocities, and static pressure variation can be detrimental to the overall airflow. But all in all, great tips. I can’t wait to design my own system.

@tomowens2720 Год назад

Watching this vid and I'm at the part where you're showing the blast gates you made. Great design. Thin nylon washers instead of the much thicker metal ones you use would still provide ease of use and make the gates even more air tight.

@toolchuck Год назад

Katz, great info on dust collection. This is a topic that can't possibly cover everyone's situation or needs. Dust collection is the science of fluid dynamics that is fairly simple from a thousand-foot perspective, but in real world application becomes extremely complicated. Especially when working with vacuums, this limits the range of pressure to operate within to a theoretical MAX of -14.7PSI. I say theoretical because even high-pressure duct collectors or extractors will never come close to -14.7 PSI, most will only see -1 or -2 while some may go as high as -8 PSI or so. Anyway, as you said, one is always learning and it's great that you share yours with us. Thank you, All the Best, Chuck

@qmoonwalker3847 Год назад

@robandsharonseddon-smith5216 Год назад

Great video, thanks. The cheap and nasty plastic blast gates are actually quite good BUT you need to make a simple modification - cut the end off. If you cut off the part where the gate usually packs in sawdust then they self-clean effectively. The tiny space that is left does leak a bit of air when the machine is in use, but it does not affect the ability of the suction to work. The very small gap and it's flat shape really limit the amount of air leakage that can occur. I think in a pro shop like yours, they are simply too flimsy, but they are really good in light use in home shops. I used a mitre saw to modify mine and it worked with a 1.5HP single stage and still works with a 3HP cyclone similar to yours.

Don't use "Duct Tape" (as in the brand, the stuff MacGyver uses, and the stuff that's actually not meant for duct work). Use aluminum tape which is actually meant to be used on duct work. It's more of a pain to get off but it's super sticky, won't break down, and won't leak.

I love the color-coded rope pulls! But (to me) it looks like you accidentally switched them. I think of green as equating to “go”, so i’d put it on the side that would open the gate if you pulled it (I.e., it’s ready for use). Yours, however, appear to be the reverse. I'm curious as to your logic. Thanks.

Instead of caulk and tape I put one layer of masking tape on the pipes before inserting them into the joints. Very tight fit but still adjustable and can easily be taken apart when needed.

@srmofoable Год назад

I've made the mistake of putting caulk on the joint before assembly. There's so much surface area it grabs ahold almost as well as cement. If you make that mistake like I did a heat gun can help save the fittings.... even if you have to cut the pipe first, the pipe can be reused in shorter locations, but those fittings are so pricey

Tip: You can bend PVC pipes to any angle you want using heat. People usually do this by filling them with hot sand, or steam. Then bending them into shape with a simple mold. Not sure how easy it is to bend those big pipes though. But I think it is doable. I.e no more 45 degree angle... but perfect curves.

And you don't have issues with static electricity buildup in the pipes? In Europe it's strictly forbidden to use plastic for ducts. Needs to be metal or you have to run copper-tape along the full length to prevent dust explosions.

@DKWalser Год назад

Dave -- Your regulators are borrowing rules from grain elevators and similar high-dust environments. The fine dust in grain elevators has been ignited by sparks from static electricity, so grounding of ducts is very necessary. Your regulators have chosen to apply those same rules to the dust collection systems in woodworking shops. But, does the same risk exist in similar, but different, environments? Several studies done in the United States say this risk of explosion does NOT exist in woodworking shops. There are at least a couple of reasons for this. First, wood dust isn't as combustible as grain dust. That may be counterintuitive, but fine flour-like dust particles ignite very easily and burn very rapidly when suspended in air. That's not as true for wood dust. Wood simply requires a higher temperature for ignition. Second, the volumes are very different in the two environments. A typical grain elevator will have a volume that is measured in hundreds, if not thousands, of cubic meters. The volume of a dust collector -- even those in a commercial wood shop -- isn't nearly that size. So, a grain elevator (as it is being loaded or unloaded) will have a lot of room above the top of the grain (or flour) to accumulate a lot of highly combustible dust. If an ignition were to occur, there could be plenty of suspended dust to fuel an explosion. That's simply not the case with a dust collector. My shop's dust collector has a volume of maybe two cubic meters. Even if an ignition were to occur, there wouldn't be enough fuel to do any damage. Yes, a dust explosion can be very powerful. But, there's a reason we don't use grain or wood dust to power cannon shells. It takes a lot of dust to produce an explosion of any real power. You simply cannot suspend that amount of dust in the air inside a wood shop's dust collection system. Bottom line: Obey the laws and regluations of your country. But, all countries have laws that are misguided.

I am a woodworker with a day job as a hazmat professional. When the people in my profession see woodworkers flailing at a problem with ill fitting masks, it's just very concerning. Johnathan and the industrial hygiene professionals here are providing good advice to protect yourselves. Capture the dust at its source. Don the best mask available when you are servicing your collection system. Mitigating contaminants starts with engineering controls (dust extraction) and process management. The PPE (mask) is your last line of defense, and professionals know this from the collected data.

@Mark-jd1fr Год назад

There is chip collection and dust collection. The airflow requirements are different for each. They are dependent on many factors including the efficiency of the hood at the tool. Most home woodworker tools have at most a 4" outlet,. Running a 6" pipe all the way to the tool and then transitioning to a 4" greatly reduces the airflow. At the pressures generated by a blower air behaves more like a fluid that is it doesn't compress.Like water through a pipe the volume is limited by closing a valve-changing the cross sectional area of the piping.In addition to losing CFM ,you also lose FPM air flow speed as the air moves into the 6" duct. If it drops below about 3700FPM it may not be able to carry chips in vertical piping.Good chip collection does not necessarily mean good fine dust (the health hazard) collection.Bill Pentz is a great resource on dust collection.

@duster8100 4 месяца назад

You did not design the rocking blast gate, the original idea is at least 15 years old and mine are at least 12 years old. Any time you reduce the pipe diameter below 6" you may as well use that diameter all the way through because the flow is restricted to the small diameter. Modify the machine port to 6" and use a 15" impeller or bigger. There is more misinformation on the net surrounding dust collection than most subjects unfortunately. A major problem and a common mistake is to instal the Y's with the inlet leg pointing down, they should always be installed with the inlet horizontal because if the machine is not used for a while the dust drops into the downward pointing leg and blocks it. When the blast gate is next opened on that leg it will be pulled up as one plug and can cause further blackages. have been doing this stuff for a living and have a fair idea of what works so take my comments for what it they are worth to you.
