Measuring the air flow rate is not definitive when dealing with larger "dust" like that produced from a drill or planer rather than a saw. With larger pieces of wood, when they go through a tee they will slam into wall of the tee, momentarily almost stopping completely, then get accelerated along the pipe until they get back up to speed. With a wye, the wood pieces lose less speed at the junction. It may not be a large enough effect to worry about, and I am not sure how to measure it. But it could be a concern. Maybe you could measure it by timing how long it takes to vacuum up a bucket of wood chips with a tee or a wye.
That's actually a good point. For me, all I have is a drill press that produces that kind of debris, and it works fine for that. But a planer or jointer might be another issue.
If I should ever get to a point where I implement a system like this I’ll probably use Y connectors unless there’s a big price difference (I suspect there’s not). If I already had a system with T connectors I’d just leave it alone, though.
I have zero idea why but for some reason I feel like I should get a life... (Just kidding, I have no intention of doing that). Glad to see you’re doing well, mate.
Glad to see you back! I thought you were going to measure how much dust arrived at the destination. And whether the motor on the dust collector was being weighed down by the restricted airflow. But hey, we don't even have a dust collection system. Mine is to open the garage door, stand at the back wall, and use the leaf blower or the air compressor. (In my house seasonally, too. lol) The dust collects outside. (I do sweep first. And we have NP100 respirators.)
Thanks, and that made be laugh. I'm not Matthias Wandel, so testing on that level is out of my league. 😂And kudos for at least getting rid of the dust somehow!
A "Y" connector will help the particles of dust and shavings travel through the pip. The only place my system blocks is on hard bends like "T" can 90 connectors, where I have two 45 bends all work well. It's just the one 90 that is by the shop vac that keeps blocking but it's to tight space to put 45s in
Funny, I was just thinking that you hadn’t posted for a while, and I’m just about to put together a system like yours and bought T’s and Y’s for the same reason. I don’t have an anemometer, and now I don’t have to buy one. Thanks!
You're quite welcome. I think you should use Ys if they're available and they work in your environment, but either way it's better than nothing, right? 😄
Zero...I love a good Easter egg. I'd be interested in seeing the same measurements at all points along your system starting at the vac. It would give a great picture of loss due to length and fittings. Thanks for the enjoyable content!
Regarding "zero": 😂I may do some more testing - not with a Y but with what effect the Dust Deputy has on the entire setup, and it would include testing the airflow at the farthest point as well as the closest one. Time will tell if I do it or not.
I've just dropped on to your channel and watched this video - i know - two years late. I can't tell you how much but your calculations are wrong almost for sure. You are dealing with a differences of 28 units over a total of 500'ish of the same units. It shows about a 5% (if you method of calculation is correct) of difference and that's not a big deal. But that 28 units will be a very different percentage if they are over ~500 than if they are over 5,000 or over 50. So, the total volume of air measured is a significant parameter and it shouldn't be inaccurate. I humbly suggest you to read the manual of the anemometer and try it again.

Yes its only 5% difference... with one connection and shop vac. Start adding bends and constriction starts to add up real fast. Also shop vac operates low volume with high pressure or speed of the air compared to chip collectors volume of air with low pressure and low speed. On the latter effect is even more drastic. Also even if its just one bend, that is still 5% more power required to move same amount of air, so you are causing extra tress to shop vac motor. Just the flex hose is creating 9 times the constriction compared to straight and even pvc or better yet metal pipe designed for dust collection.
This has been properly tested many times. Also just testing one connector doesn't really help. It is about the total volume and speed of air being moved throughout the entire system. Air slows down around corners. If you have a full-fledged ducting/piping system, having it littered with t-connectors will make a difference - sure in your case you might not see the difference, but the difference exists nonetheless.
Glad to hear you and yours are ok. As far as the test goes I notice you have a thein type baffle which keeps your vacuum working more efficiently (ie filter stays cleaner). If I was going to spend money or time that would be my first place to start. I'm not an expert but I think the difference may become greater the more particles being pulled thru the pipe. I think the difference between "t"s and "Y"s is due to turbulence at the joint. So like some others mentioned besides joiners and Planners, lathes, might see a bigger difference. I'd also suspect that the quality (air tightness) of your system and gates will have a bigger impact than the joints themselves. Just my guess. stay healthy.
Thanks for the comment, Jack. I am actually thinking about doing some testing of the Dust Deputy, with and without, and see what the differences are in various situations. Time will tell if I actually do it, but that's the plan right now.
I am using a HD Dust Stopper with a Rigid shop vacuum. I don’t know how it compares to a dust deputy.i believe it was less expensive but may not be as efficient. It is easy to setup and use. My biggest complaint is that I don’t pick up paper or plastic bags off the shop floor if they drop and they can clog the dust stopper and it is hard to clear as it makes it into the device but not out.. Also the pipe that comes with it is too short if you mount the bucket with the baffle on top of the shop vac which I do. So an extra 12-18” would have been perfect. It works but don’t know if others are better. I found that if it falls over when vacuuming that stuff can make it into the vacuum container but otherwise it remains very clean. I am concerned with the really fine dust that may get thru everything and so I run a fan with a filter that supposedly can capture small particles. It does get dirt over time but I can’t tell if it goes thru the vacuum or not. Oh just a random fact I tried a dust deputy knock off and it didn’t work well at all. Since it came with no instructions maybe it was the way I set it up can’t tell. I just went with dust stopper.
@@jackmiller3628 I've had some long conversations (email) with the inventor of the Dustopper (I have a video comparing it with the Dust Deputy). He's a really nice guy and I'm happy his product is succeeding. He's very smart and has done a lot of research - he's basically an expert in air flow or whatever it's called. My only real complaint was that it was louder, at least on my system. It seemed to work about as well as the DD - maybe slightly less, but close enough. As for the bucket tipping over, I wonder if you put a brick in the bottom of the bucket, that might help?
The Newbie Woodworker I thought the same thing concerning the brick but decided to mount the bucket with the dust stopper on top of the vacuum and attack it so you would have to pull the whole vacuum over. Less space needed but tall.

It's good to hear from you, mate. 👍🏾 So many opinions in such a small space... Thank goodness for the respect of individualism! 😉 Good on ya, take care and stay safe, mate 👌🏾
Something fishy about the claim volume vs speed but I can't put my finger on it. Regardless so glad you made this video -enjoyed it thoroughly, just like all previous ones.I was wondering whatever happened to The Newbie Woodworker. Glad all is well. By the way, I too will use the cheaper and more convenient join when I set up the workshop at my place.
I may have the details wrong, but there is definitely a major difference in how they work. I've heard that from people in the business who know a lot more than I do (which honestly doesn't take much). As for which joints you use, use whatever you can afford, and whatever works. 😄
in my 10'x10' shop i have a shop vac for general cleaning. i spent under $15 to collect dust. a used $5 leaf blower and $10 4" flex hose for my table saw and for my 2 scroll saws i have 2 second hand home cyclone vacuums ran through my foot switches. i traded them for custom portraits. not only is "necessity the mother of invention" but so is being broke.
The y will give you a better waste flow...no sharp...everybody down then a sharp right or left turn...I also use a similar set up as yours using clear 2 1/2” pipe and fittings y’s and elbows with grounding...thanks for your vids.
In the uk here, I have 4” or actually 100mm Id duct tubing but the type I got (due to being a lot cheaper ) only has T not Y joints. It seems to work just fine but I don’t have much experience to compare it to. Cheers
Hi good video. I use 2" pipes for my dust collection with 2" Flexi hose. I am just redesigning my workshop to make more room. Trying to get all my saws in the same general area to cut down on the length of piping used, Ive only got a small garage. In the UK we can get T connectors with a slight bend in one direction depending on how you fit it. It does seem to make a difference. One thing I did notice on the last setup was the tendency for the chips from the Planer Thicknesser to clog up on right angle 90 degree bends so I am going to use two 45 bends to eliminate that. Keep up the good work, Harry
I have a life so I won't mention zero, I guess. Though I'll keep your video in mind if ever I manage to install a dust collection system that doesn't rely on the shop-vac hose being moved around on each tool change.
I don't know enough about anemometers to know if it's good or not, but the fact I couldn't figure out how to enter decimals less than 1 makes it not a good choice for me. This is it, though: www.amazon.com/gp/product/B01FGYBBBG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1.
Thanks for the video and the candour to mention the problem with entering the value. And - zero - I won’t take offence as my life is about trying to knowing know all the nitty gritty details 😅
I was cutting small pieces of oak for a thread stand for my sewing quilt nut wife. I was standing at my tablesaw and I said first how did Dan do this and then Dan hasn't posted a vid in a long time. Then miraculously you post a vid. I hate this dust collection mess. I have watched many vids on you tube and there are too many opinions. I think the test is does the sawdust end up in the bucket. Glad you are feeling ok.
At that difference the only benefit of the Y over the T would be the angle of attack with the wood chips/dust. At full speed the chips/dust will slow down less with the Y vs the T which is helpful if you get come condensation in the lines but it really is minor. For such a small setup the thing that would help the most is to make sure you have as few leaks in the system to help maximize the vacuum at each port.
Hey great stuff. Hows the thumb? I am going to use the shop vac and t and y connections for my triple location. Dust collection system after i finsh building the table saw/ router extension bench with a concealed shop vac hideaway cabinet. Question...... have you ever had the need to make a sacrificial fence for dadoing or ripping on your table saw.
@@TheNewbieWoodworker sorry for the delayed reply yes. perhaps you can make a video how and why a sacrificial fence is useful and would you create multiple sacrificial fences for different dado widths while making tongue and groves on MDF and plywood for cabinet making. thanks for your time .i really enjoy your videos and am learning a lot. i look forward to more videos m.a.m.
@@michaelmassetti2575 Stumpy Nubs has a good video on sacrificial fences: ua-cam.com/video/VbS0-nSCrzo/v-deo.html. And I use the same one over and over again. It's only real purpose is so you don't cut your rip fence.
Thanks for that, you are right if you are using one machine per operation. Your dust vacc works on vacuum a dust extracter works on air volume. A dust extracter is designed to move X amount of air and does not work as efficiently if it is not allowed to move that amount of air. The best way to make this happen is to install a gate on a Y piece that allows you to balance the air flow, giving you the most efficient use of this machine. As you said a 5.5% drop in efficiency does not matter with a vacuum, unless you are using multiple outlets. May I say your design is brilliant for a vacuum system. By the way my background is in particulate air movement, Stewart
Thanks, Stewart, for confirming what I was thinking, and thanks for the compliment. I'm certainly no expert - far from it, and I'm just trying to help as best I can. As an aside, I've delved into "fine particle" collection, and I just end up shaking my head and saying "I can't hear you" really loudly. I'm not sure why I'm mentioning it, other than I thought it might give you a chuckle. :)
@@TheNewbieWoodworker Hi the problem with fines in particular air is that you need to reduce the velocity in any separator to allow the without doubt light weight particles to drop out and not be taken to any filters you may have. Heavy particles are relatively easy to remove in separators (cyclones) but not fines like sanding dust.
😂And that's a great idea - there have been a lot of times I couldn't get a UA-cam video to pause on a single frame. When I'm at my computer I usually just download the video but I like your idea better.
Entering "Zero", and get a life... OK... check! - but I think you justified your analysis as a relative number vs. absolute. So a thought about your dust collector setup: the run in your workshop is short compared to other shops, so the ~ 5% difference would only make a small increase in efficiency, not that beneficial to swap them out... but the fact that you can measure it at all is impressive. However, I think if a shop had longer runs, the Wye's would make a greater contribution... but is that true? I can't prove it, just a guess (I'm sure there are papers and research done on this) BTW: I am thinking about adding some dust collection to my weekend workshop one day with a long-ish runs (20 to 30 ft.). Should I use Tee's or Wye's ?? I think Wye's... right?
Regarding "zero", 😂. For your last question, I think you should always use the most efficient methods unless you've got a good reason not to. As to the other things, I haven't a clue but I figure if it gets most of the dust, then that's a win. Except for table saws - it's not always possible to get really good dust collection with them, depending on how they're made. So people who search after the perfect table saw dust collection are asking for disappointment.
@@TheNewbieWoodworker I am rewatching your dust collection basics video and thinking about the components blast gates, hoses, clamps, etc. and it's a good resource... I think this is good enough for my purposes... I'm not planning on becoming a professional woodworker, I'm actually a full-time firmware engineer that dabbles on the weekend with power tools 😁 so while, yes, I can stress over "perfect," my goal is to make things in my shop. Surprising how much sawdust is generated from my tiny projects! and don't even get me talking about the amount of sawdust from making pocket holes... However, not covered in your video, but I'm thinking of adding one anyway, are one of those air circulator filter fans... like a Powertech or WEN, they hang from the ceiling and clean up the fine particulates in the air. Thanks so much for posting videos they are inspirational

Just kidding. Great video. Thanks for sharing.
Greetings from Switzerland 🇨🇭
😂And thanks. 😄
It's good to hear from you, mate. 👍🏾
So many opinions in such a small space...
Thank goodness for the respect of individualism! 😉
Good on ya, take care and stay safe, mate 👌🏾
Thanks! You stay safe too.
Zero, lol. Couldn't help myself.

Something fishy about the claim volume vs speed but I can't put my finger on it. Regardless so glad you made this video -enjoyed it thoroughly, just like all previous ones.I was wondering whatever happened to The Newbie Woodworker. Glad all is well. By the way, I too will use the cheaper and more convenient join when I set up the workshop at my place.
I may have the details wrong, but there is definitely a major difference in how they work. I've heard that from people in the business who know a lot more than I do (which honestly doesn't take much). As for which joints you use, use whatever you can afford, and whatever works. 😄
in my 10'x10' shop i have a shop vac for general cleaning. i spent under $15 to collect dust. a used $5 leaf blower and $10 4" flex hose for my table saw and for my 2 scroll saws i have 2 second hand home cyclone vacuums ran through my foot switches. i traded them for custom portraits. not only is "necessity the mother of invention" but so is being broke.
LOL - absolutely! Whatever works, works. John Heisz just sweeps with a broom in most cases! 😄
The y will give you a better waste flow...no sharp...everybody down then a sharp right or left turn...I also use a similar set up as yours using clear 2 1/2” pipe and fittings y’s and elbows with grounding...thanks for your vids.
Thanks! 😄
In the uk here, I have 4” or actually 100mm Id duct tubing but the type I got (due to being a lot cheaper ) only has T not Y joints. It seems to work just fine but I don’t have much experience to compare it to. Cheers
I think that not having something to compare to is the secret to happiness. Seriously - if you don't know, then you won't care! 😄
Short and cheery. Enjoyed. Who would have thought comparing T's and Y's would give a bright start to the day.
Cool! Glad I brightened the start of your day. 😄
Hi good video. I use 2" pipes for my dust collection with 2" Flexi hose. I am just redesigning my workshop to make more room. Trying to get all my saws in the same general area to cut down on the length of piping used, Ive only got a small garage. In the UK we can get T connectors with a slight bend in one direction depending on how you fit it. It does seem to make a difference. One thing I did notice on the last setup was the tendency for the chips from the Planer Thicknesser to clog up on right angle 90 degree bends so I am going to use two 45 bends to eliminate that. Keep up the good work,
Harry
Thanks, Harry. I hadn't thought about a planer or jointer (I don't have either), but that's a great point.
I have a life so I won't mention zero, I guess. Though I'll keep your video in mind if ever I manage to install a dust collection system that doesn't rely on the shop-vac hose being moved around on each tool change.
LOL, and thanks. The one big advantage of moving the shop vac around is that you'll get MUCH stronger suction.
Zero. I wish I had a life. 😢
Jk, haha. That must have been a really frustrating function of the tool.
😂And yes, it was. 🤬😄
Could you share the brand/ model number of the anemometer? Are you happy with it?
I don't know enough about anemometers to know if it's good or not, but the fact I couldn't figure out how to enter decimals less than 1 makes it not a good choice for me. This is it, though: www.amazon.com/gp/product/B01FGYBBBG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1.
@@TheNewbieWoodworker thank you.
@@dougprentice1363 👍
Thanks for the video and the candour to mention the problem with entering the value. And - zero - I won’t take offence as my life is about trying to knowing know all the nitty gritty details 😅
😂Thanks, and you're welcome. 😄
I was cutting small pieces of oak for a thread stand for my sewing quilt nut wife. I was standing at my tablesaw and I said first how did Dan do this and then Dan hasn't posted a vid in a long time. Then miraculously you post a vid. I hate this dust collection mess. I have watched many vids on you tube and there are too many opinions. I think the test is does the sawdust end up in the bucket. Glad you are feeling ok.
Glad to be back. And yes, that's my feeling too - does it puts the dust in the bucket? Good enough for me. 😄
At that difference the only benefit of the Y over the T would be the angle of attack with the wood chips/dust. At full speed the chips/dust will slow down less with the Y vs the T which is helpful if you get come condensation in the lines but it really is minor. For such a small setup the thing that would help the most is to make sure you have as few leaks in the system to help maximize the vacuum at each port.
Thanks, and I agree. 😄
Good to hear from you again!
Thanks! 😄
Happy to see video from you.
Thanks! 😄
Where you been?
Taking a break.
Welcome back.
@@LongIslandBK Thanks! 😄
Zero issues here. I agree it's not enough of a difference to make changing your setup or losing the valuable space worth it.
Thanks - that was my thought too. 😄
Hey great stuff. Hows the thumb? I am going to use the shop vac and t and y connections for my triple location. Dust collection system after i finsh building the table saw/ router extension bench with a concealed shop vac hideaway cabinet. Question...... have you ever had the need to make a sacrificial fence for dadoing or ripping on your table saw.
Thanks. Yes, I've used sacrificial fences many times. Is there something I can help with?
@@TheNewbieWoodworker sorry for the delayed reply
yes. perhaps you can make a video how and why a sacrificial fence is useful and would you create multiple sacrificial fences for different dado widths while making tongue and groves on MDF and plywood for cabinet making.
thanks for your time .i really enjoy your videos and am learning a lot. i look forward to more videos m.a.m.
@@michaelmassetti2575 Stumpy Nubs has a good video on sacrificial fences: ua-cam.com/video/VbS0-nSCrzo/v-deo.html. And I use the same one over and over again. It's only real purpose is so you don't cut your rip fence.
@@TheNewbieWoodworker thanks for the reply

Good to know! Good job & God bless!
Thanks, and you too. 🙂

OK, you're off the hook. 😛
I will have a system that is small. I plan on cheaper cost.☺ Thanks for information.
You're quite welcome! 😄
This was an nice experiment and always happy to se your videos !
Take care and be safe :)
Thanks! And you too.

What can I say - I'm retentive like that
@@GalaxyStranger01 Ditto!
You and your family stay healthy, thanks for the video.
Thanks, and you too!
Thanks for that, you are right if you are using one machine per operation. Your dust vacc works on vacuum a dust extracter works on air volume. A dust extracter is designed to move X amount of air and does not work as efficiently if it is not allowed to move that amount of air. The best way to make this happen is to install a gate on a Y piece that allows you to balance the air flow, giving you the most efficient use of this machine. As you said a 5.5% drop in efficiency does not matter with a vacuum, unless you are using multiple outlets. May I say your design is brilliant for a vacuum system. By the way my background is in particulate air movement, Stewart
Thanks, Stewart, for confirming what I was thinking, and thanks for the compliment. I'm certainly no expert - far from it, and I'm just trying to help as best I can. As an aside, I've delved into "fine particle" collection, and I just end up shaking my head and saying "I can't hear you" really loudly. I'm not sure why I'm mentioning it, other than I thought it might give you a chuckle. :)
@@TheNewbieWoodworker Hi the problem with fines in particular air is that you need to reduce the velocity in any separator to allow the without doubt light weight particles to drop out and not be taken to any filters you may have. Heavy particles are relatively easy to remove in separators (cyclones) but not fines like sanding dust.
@@stewartenglish3724 Good point - thanks.
Zero :/ haha. Anyway, I appreciate the idea and the video!
😂Thanks!
It is indeed good to see another video from you, Dan. Looks like the benefit of switching from T to Y connectors would be pretty close to ... zero.
Thanks, and LOL at "zero".
On vacuum only dust extractor definately
@@stewartenglish3724 👍
They may always be better but what works for you is best
Amen to that, for sure!
Thank you! Always honest insight.
You're welcome, and thanks. I try to be as honest as I can. 😄

😂And that's a great idea - there have been a lot of times I couldn't get a UA-cam video to pause on a single frame. When I'm at my computer I usually just download the video but I like your idea better.
@@TheNewbieWoodworker I certainly tried a lot... But it just wouldn't stop for me. I got annoyed with my inability and kind of cheated I guess 😉
@@Faustustopheles Not a cheat! Creative thinking. 😄
Appreciate you taking the time to share you have a blessed day

Entering "Zero", and get a life... OK... check! - but I think you justified your analysis as a relative number vs. absolute. So a thought about your dust collector setup: the run in your workshop is short compared to other shops, so the ~ 5% difference would only make a small increase in efficiency, not that beneficial to swap them out... but the fact that you can measure it at all is impressive. However, I think if a shop had longer runs, the Wye's would make a greater contribution... but is that true? I can't prove it, just a guess (I'm sure there are papers and research done on this) BTW: I am thinking about adding some dust collection to my weekend workshop one day with a long-ish runs (20 to 30 ft.). Should I use Tee's or Wye's ?? I think Wye's... right?
Regarding "zero", 😂. For your last question, I think you should always use the most efficient methods unless you've got a good reason not to. As to the other things, I haven't a clue but I figure if it gets most of the dust, then that's a win. Except for table saws - it's not always possible to get really good dust collection with them, depending on how they're made. So people who search after the perfect table saw dust collection are asking for disappointment.
@@TheNewbieWoodworker I am rewatching your dust collection basics video and thinking about the components blast gates, hoses, clamps, etc. and it's a good resource... I think this is good enough for my purposes... I'm not planning on becoming a professional woodworker, I'm actually a full-time firmware engineer that dabbles on the weekend with power tools 😁 so while, yes, I can stress over "perfect," my goal is to make things in my shop. Surprising how much sawdust is generated from my tiny projects! and don't even get me talking about the amount of sawdust from making pocket holes... However, not covered in your video, but I'm thinking of adding one anyway, are one of those air circulator filter fans... like a Powertech or WEN, they hang from the ceiling and clean up the fine particulates in the air. Thanks so much for posting videos they are inspirational
@@raymitchell9736 I actually have a WEN and it works great. And it's no surprise that woodworking interests you, being a firmware engineer. I'm a retired software engineer, and I've discovered that engineering is engineering, no matter what. 😄
Very useful thanks
