I love the fact that your shop is in constant evolution. Seems like a smaller dust collector for each machine makes more sense since it takes less space and is more convenient to use. Keep up the great content!
Just came back after I've built the same dust collector for my sanding machines with a small blower fan. It just works, quiet and efficient. I think this video and approach is just amazing. Thanks.
Simple, easy, practical with data to back the results. And as usual, cost effective. Channel should be named " Woodworking with Engineers ". Great video as always.
I've been driving myself mad with my dust problem, no collection yet, or time to woodwork but I've been thinking about it a lot. This set up(one at every tool), and then once in a while going thru all of them with a shop vac and cyclone is probably going to work out perfect for my spare time woodworking endeavours. Thank you! Now to figure out the lathe dust...
Wow, I was thinking of making one of these today then saw this comment. I have some extra lexan that's been sitting around forever. Doing this for sure now
And people upgrade from little ones to big ones all the time. Just watch your local classifieds. I paid $30 for my 1HP and $50 for my 2HP, both Harbor Freight models (well regarded) in like new condition.
No John. It isn't. When you factor in all the tubing that has to be cleaned in a central system you have much less work with individual boxes. Plus , every time you add a bend in the collection tube you lose efficiency and the same is true with the longer the run. So, you are wrong about everything. CONGRATULATIONS
I used to watch your channel and I lost my device to water damage. I stumbled onto this podcast and I’m am so glad I did. I’ll get my subscription in and never wander off again. Promise!
Great idea. I did something similar in my old shop. Table saw on one, Miter Saw on another, and everything else used a modified bucket collector. It worked really great, and I avoided having ducting everywhere with blast gates to play with.
I have the same planer. I just fit some 4" PVC pipe to the dust port and route it into a large garbage can. I bungee some geotextile (nonwoven filter fabric) over the top. It collects all the chips and dust no problem.
Being subscribed means that you get to see the video on the same day that it was posted and by the time you watch it it has 50,000 views. Wandel.. the Coolest woodworking nerd the planet has created thus far.
I like the idea, my only criticism is that now you have half a dozen dust collectors to empty instead of one. I think its a good system though because you do save so much money, time and effort not having to deal with the ducting.
I think I saw this video years ago, but at the time, I lived in a place that had a 4-car garage. So space was less of an issue at the time. My current workshop is much smaller and it would be really nice to not have duct work all over and a dust collector as well. So I think I'll give this a go for my compound miter saw and see how it goes. Thanks Matthias!
I love your videos Mattias, I wish I had half of your skill and a quarter of your tools. With these filters that you have made I don't understand why you don't have the suction at the top. Having the vanes of the filters running horizontaly or even diagonally (A frame) would leave shelves for the dust to build up on. If the filter was mounted in the ceiling of the box and suction at the top, the dust has little to settle on on the filter. Position the inlet maybe 1/3 to 1/2 way up the filter box and have a hopper below. Once a buildup of dust reaces a critical point, the weight of it would drop clumps of dust back down into your hopper. In effect this would self clean the filter to a large degree, you would only have to empty your hopper and clean off the finer particles from time to time. I look forward to more of your videos and your thoughts.
I think you're right Matthias. I was going to wire up blast gates and current sensing modules all over the shop. Now I think I'll just have a separate dust collector for each machine. Cheers
Interesting indeed! The concept of a dedicated dust collector at the point of generation has always intrigued me. But never thought it would work well. Yours appears to do fine. Thanks!
Denny Bartley I have a video on my channel .where I started last winter but I haven't had a chance to work on it anymore. But it is something that needs to be done.
actually ive been making two bucket cyclones with old vacuum cleaner motors for quite a awhile i have three of them. One hooked up to table saw, one on planer and another i use for pulling mouse nests out of cars(dont ask it really stinks up a regular shop vac) Royal/dirt devil vacuums have a flange on the motor that fits the cone shaped filter from same vacuum perfectly.
Commercial AC tech here, I can confirm cheaper filters merv 7 and merv 8 give much better airflow. I always recommend homeowners buy the least expensive pleated filters. Higher merv and allergy filters restrict airflow and do not keep the equipment any cleaner.
In this case, the problem wasn't lack of airflow, but lack of actually filtering out dust. The expensive filter had less air resistance, but was letting thru not just fine dust, but also coarse sawdust.
Interesting, I would have thought the more expensive filter would have a higher drop across it. Resulting in a higher return static at the collection point. If the filter was allowing large dust particles to bypass then the price is even more of a rip off.
Because the expensive filter restricted airflow, it might have been possible that the saw dust was being forced around the edges of the filter. They may have opened up, after the vacuum would warp the shape of filter.
I agree... I think if I was going to use a setup like this, I'd build a filter frame out of aluminum angle or channel, and use a filter-sized portion of expanded metal to "support" and SEAL the filter in the box... I also don't see why he doesn't change the box design so at least the primary filter could be changed out without taking the panel off the box.... If the tolerances were correct, you wouldn't lose but an insignificantly small amount of vacuum with MY design idea...
I've always wondered about the idea of makchining my own air blowers out of metal, but I've never thought of using wood, I never would have thought of it as a good material to make one out of until seeing your videos, you've made a couple of them and they seem to really work well.
I had this same thought a few years ago and always wondered if it would work (never followed through on it though because I couldn't find a cheap enough blower). Thanks for proving that it does! I never thought to use blower motors from a water heater...brilliant!
those high dollar air filters cause my A.C motor to get hot .hard to pull air thru ...man you are great at making this stuff .and i copy every thing i can from you .i have emphysema had to retire need the clean air ..keep it up please my wood shop is going to look great and clean air ..all because of you
Great video! I think this especially makes sense for the tools like sanders that only create fine dust. No need for a huge dust collector when something like this will do the job just fine.
back on the farm my grandpa used fruit flies to collect dust. grandma and ma ran the fruit fly farm. they bred those flies for miles. the good trick to dust collecting with fruit flies is to rub raspberries on your lumber so the flies know what to grab
Great idea. The hassle of a single large dust collection system has always prevented me from going that route. Putting one on each machine is great cause you can move the tool to accommodate any work without having to worry about moving the collection lines also.
It seems unnecessary to use two identical filters. I could be wrong, but to me this is a little like stacking two identical spaghetti strainers on top of each other. Any particle that’s small enough to pass through the first strainer will also pass thought the second strainer. To improve your dust collector, would it make sense to try using two non-identical filters? (That is, filters that are designed to catch different sized particles.) Anyway, thanks for the vid. Enjoyed it as usual.
Correct. If both filters are the same micron count most of the stuff that makes it through the first one can make it through the 2nd filter. Infact all a 2nd filter really does is restrict airflow so its actually hurting the dust collecting process.
Technically, You're not even wrong. Filters like these (MERV 8) are not like a strainer, the analogy is close, but incorrect. If you look into their ratings, they are capable of capturing the particles all the way down to 3 microns, and they are rated according to their efficiency at doing so. If the cheapest filter has a 70% efficiency at 3 microns, and the second one 70% also, it adds up to more 3 micron particles collected with two filters than one. 70% at 3 and 90% at 10 microns, doesn't mean 0% at lower particle sizes also. And... even with a spaghetti strainer, stacking two means statistically less noodles going through.
@@rolfbjorn9937 Agreed - for the math-inclined, 2 filters with 70% efficiency acting in series _should_ net you ~90% total (30% of inflow makes it through the first, 30% of that makes it through the second --> 9% total passed, or 91%). Makes me wonder if there's some value to stacking my higher-MERV filters...
Excellent. I headed the same way for my new shop six months ago but totally missed the idea of folding the filters - Brilliant!!! The Inducer wheel impeller is much more efficient and meets all of my needs including a CNC router. The other great thing about your design is that the box can be sized and flipped horizontally and vertically as needed. Air molecules don't mind.
I have a portable dust collector on wheels that I connected to the bottom of my table saw. (built a box beneath it to contain the vacuum.) That takes care of the majority of the sawdust. But for the remaining what I do is to directly connect a small shop van and have the business end of the hose hovering just above where the blade meets the wood. I took an arm from an old arm lamp and use that as a convenient holder for the collection hose. The combination works great. And I think I save a step as any residual dust goes straight into the shop vac.
I imagine you in the shop pointing to all your appliances like Oprah. "You get a dust collector, you get a dust collector, EVERYONE GETS A DUST COLLECTOR".
I have an old powermatic disc/belt sander that has a belt driven blower underneath/ a switch to toggle belt or disc and a filter bag. Came this way from the factory.
Get a Dust Deputy; I have one connected to my CNC router and love it. The DD bin will be full in a few weeks but the vacuum's filter and container are still clean and empty.
I like the way you speed up your videos , if I have to watch someone on standard time drive in all the screws, tighten all the bolts etc. , I go on to the next video .
I've been doing something similar with those cheap little shop vacs + a cyclone/thien baffle. I like your solution better; more airflow, larger capacity and much quieter too!
I love how compact these are. Personally I think I'd like a huge dust collector with ductwork running to each machine in my shop someday, but think is certainly a good alternative.
I started doing this a couple of years ago. no ductwork all over the place and a lot quieter. I put the little dust collectors in the cabinet under the machine.
Loving this idea! And with your permission going to use it in my workshop too. The only problem I have is finding a good source for all the electrical parts.
I had the same feelings re a whole shop dust collector vice individual dust collector at each power tool, particularly those which generate large volumes of dust. However my approach is to use small shop vacs connected to relay switch that has a built in time delay when stopping. It's a tad expensive but I don't have the resources to look for blowers at flea markets, garage sales and dumpsters. However Mathias' approach and design are very entertaining.
The secondary filter being clean makes perfect sense because as the first filter becomes more plugged it actually filters better but with less efficiency of air flow.
Very nice work. Very professionally done. Also enjoy your FF editing when showing the labor (sawing, drilling, etc.). Makes for a very enjoyable watch. We can see how you did the work (laying out, transferring, etc.) without watching paint dry. (c;
Your two garrison filters were allergen filters while that 3m was one of the lowest quality pleated 3m filters. Still probably a better quality filter, just doesn't trap as fine of dust. For filter setups, you normally want to use a pre-filter (cheap, fairly coarse collection.) and then your fine filter (allergen or other fine/ high filtration filter) The logic is your fine filters are better quality/ more expensive and catch the small stuff the cheap/coarse filter missed. The cheap filters clog up with large stuff but keeps the large material off the fine filter. They can then be vacuumed or tossed. This is a more efficient and longer lasting design than just 2 fine filters in series or 1 coarse filter like that 3m was. (3M has a large array of different filtration qualities. But cheap filters for sawdust collection are probably best. Go with the good ones for your home and family.) Great build and I like how well those pulled in the sawdust.
I want your workshop!!! :D Really interesting that the cheap filter outperforms the Filtrete one. You can make an even better one with a dedicated metal cabinet for the filter housing with a 5" thick filter. It has better filtration performance, and a larger surface area, meaning it can perform longer without having to be cleaned. These filters are for furnaces, and they are rated at MERV11 or MERV14 - the air cleaning capabilities are far higher than a bag filter or the thin furnace filters you are using. Of course, your filters appear to work just fine for a workshop, and thus are not an issue.
You are a legend, Thank you for providing us with all your videos on youtube people really underestimate how much goes into these videos, Thanks Matthias :)
HVAC duct guy here. By cutting open the shroud further, you didn’t increase total airflow (CFM). What you did do is decrease velocity (FPM) because you increased the internal volume without changing motor speed. And also introduced turbulence because the blades aren’t directing the airflow out their intended, engineered opening. Not that it creates any catastrophic failure, but you can be filtering much more particles per minute if you stick to the designed openings as closely as possible.
Matthias Wandel what instrument did you use to measure the airflow? When doing measurements, you have to take things into consideration such as static pressure, velocity pressure, turbulence etc as part of the equation. Thanks for the reply

I love how you clean your dust collector filter with another dust collector
its the big one that goes trough like a super big container remember ^^ but still funny ^^
JackHog123
Filterception
I thought the same thing LOL !!!
Think that if he collected the dust from the filter with that same dust collector what he cleaned.
I love the fact that your shop is in constant evolution. Seems like a smaller dust collector for each machine makes more sense since it takes less space and is more convenient to use. Keep up the great content!
Thanks for promoting my filters, nothing gets past a Garrison.
You saw the chance and you took it.
Lol!!
You should get rid of them, they're just sitting there collecting dust...
This is one of the funnier comments ever
Turn them into speaker enclosures
lol that's actually so funny
Owo 😂
Thats the entire point!!!
I love the editing in your videos. So fast paced! Never a dull moment.
I like it even more when the trend on TH-cam is to dilute the content to reach 10:01 ..
Just came back after I've built the same dust collector for my sanding machines with a small blower fan. It just works, quiet and efficient. I think this video and approach is just amazing. Thanks.

Great idea. I used to have a long 150 foot garden hose. Now I have 3 40 foot hoses. Saves so much time dragging it around.
I've been driving myself mad with my dust problem, no collection yet, or time to woodwork but I've been thinking about it a lot.

Now to figure out the lathe dust...
Dear Matthias Wandel, You always manage to put a smile on my face, no matter how many times I review your good works, and educating videos. THANX!
Your dust collection videos are a great use of TH-cam, sourcing your fan base for working on everybody's health. Thanks for the community effort!
For some reason the fans and dust collectors you make are very satisfying to me.
you should put lexan covers on them so you can see when the filters are getting full
Wow, I was thinking of making one of these today then saw this comment. I have some extra lexan that's been sitting around forever. Doing this for sure now
I think several small collectors is a great idea. Your results validate the concept. I too dislike a larger system's infrastructure.
And people upgrade from little ones to big ones all the time. Just watch your local classifieds. I paid $30 for my 1HP and $50 for my 2HP, both Harbor Freight models (well regarded) in like new condition.
I agree, I like this idea too, great work Matthias
A disadvantage is that each collector has to be emptied individually, multiplying the work involved in an already set-up system.
I would much prefer to empty a small one as needed than a large one basically ever.
No John. It isn't. When you factor in all the tubing that has to be cleaned in a central system you have much less work with individual boxes. Plus , every time you add a bend in the collection tube you lose efficiency and the same is true with the longer the run. So, you are wrong about everything. CONGRATULATIONS
I'm always amazed at the little nuanced design decisions Mattias see and solves to make a really nice piece of hardware.

You've always impressed me Matthias, I don't think I've seen anyone as dedicated to good dust collection as you are. It's pretty neat!
I have the same planer. I just fit some 4" PVC pipe to the dust port and route it into a large garbage can. I bungee some geotextile (nonwoven filter fabric) over the top. It collects all the chips and dust no problem.
In a related story, the marketing team for Garrison's filters is said to still be celebrating with cocaine and strippers to this day.
I other news, twelve 3M engineers have been found dead in a dilapidated factory, having committed seppuku.
lawling pretty heartily.
Ironic, since they are shorting a fine powder up their nose.
What? Where? Strippers in dust?

I must built one of them. You always are a big source of inspiration. Thank you!
this channel is my happy place
I like that you give an update after
The projects were put to use! Excellent job!
That is a really interesting approach to dust collection.
And they're quieter, and more energy efficient also, I would imagine. Nice work!
Inimbrium that was my first reaction. Quieter!
Your woodworking skills leave everybody else in the dust !
I think I saw this video years ago, but at the time, I lived in a place that had a 4-car garage. So space was less of an issue at the time.

Really good work on that lid, I don't know why but I find that lid awesome, the way it fits perfect
I have made one of these dust collectors for my radial arm saw and it works awesome!
Interesting indeed! The concept of a dedicated dust collector at the point of generation has always intrigued me. But never thought it would work well. Yours appears to do fine. Thanks!
I like this idea and have been working on some similar ideas with all of the vacuum cleaners I find in the trash.
Please post a video if you get it to work.
Denny Bartley I have a video on my channel .where I started last winter but I haven't had a chance to work on it anymore. But it is something that needs to be done.
actually ive been making two bucket cyclones with old vacuum cleaner motors for quite a awhile i have three of them. One hooked up to table saw, one on planer and another i use for pulling mouse nests out of cars(dont ask it really stinks up a regular shop vac)
Royal/dirt devil vacuums have a flange on the motor that fits the cone shaped filter from same vacuum perfectly.
Jacilynn S are the cyclones homemade or store bought ?
Its a modified version of Mattias's own two bucket cyclone. I just mount the vacuum motor right on top with the filter sticking down in the middle.
I really like watching you make these mini dust collectors!
Commercial AC tech here, I can confirm cheaper filters merv 7 and merv 8 give much better airflow. I always recommend homeowners buy the least expensive pleated filters. Higher merv and allergy filters restrict airflow and do not keep the equipment any cleaner.

Finally i see this. Thats what happens when u dont seal the filter.
I agree... I think if I was going to use a setup like this, I'd build a filter frame out of aluminum angle or channel, and use a filter-sized portion of expanded metal to "support" and SEAL the filter in the box...
I also don't see why he doesn't change the box design so at least the primary filter could be changed out without taking the panel off the box.... If the tolerances were correct, you wouldn't lose but an insignificantly small amount of vacuum with MY design idea...
4:03 damn thats such a great detail, made with a perfectionist mindset. I salute you!
Good work man! You're an inspiration for us guys who live in the city who don't have room for a workshop or a shed :)
Love your DIY videos mate! I like to watch them while eating. It pleases me very much. Thanks!
I've always wondered about the idea of makchining my own air blowers out of metal, but I've never thought of using wood, I never would have thought of it as a good material to make one out of until seeing your videos, you've made a couple of them and they seem to really work well.
Wow. At 3:48 I feel like a fool for not realizing the end of a caliper can be used to measure too. Thank you!
Jack yep works great as a depth guage for measuring mortices or bolt holes
I had this same thought a few years ago and always wondered if it would work (never followed through on it though because I couldn't find a cheap enough blower). Thanks for proving that it does! I never thought to use blower motors from a water heater...brilliant!
Your lunacy is so practical.
thanks for posting these "experiment" videos as opposed to a simple "how to" -- it's much greater learning why certain things are done -- very cool!!
those high dollar air filters cause my A.C motor to get hot .hard to pull air thru ...man you are great at making this stuff .and i copy every thing i can from you .i have emphysema had to retire need the clean air ..keep it up please my wood shop is going to look great and clean air ..all because of you
Hi just want to say I enjoy more watching you doing wood than the tractor
Great video! I think this especially makes sense for the tools like sanders that only create fine dust. No need for a huge dust collector when something like this will do the job just fine.
back on the farm my grandpa used fruit flies to collect dust. grandma and ma ran the fruit fly farm. they bred those flies for miles. the good trick to dust collecting with fruit flies is to rub raspberries on your lumber so the flies know what to grab
how does that work?
it was passed down from his granddad. back then they tricked the flies to think trees are fruit
+Corncob Johnson so the flies grab the wood, thinking it's fruit and fly away?
no one knows for sure but this is the general consent
+Corncob Johnson I wanna see a video of that lol
Great idea. The hassle of a single large dust collection system has always prevented me from going that route. Putting one on each machine is great cause you can move the tool to accommodate any work without having to worry about moving the collection lines also.

@@rolfbjorn9937 Agreed - for the math-inclined, 2 filters with 70% efficiency acting in series _should_ net you ~90% total (30% of inflow makes it through the first, 30% of that makes it through the second --> 9% total passed, or 91%). Makes me wonder if there's some value to stacking my higher-MERV filters...
I like it. The redundancy is nice; if one machine's collector breaks down, you can borrow from one of the others in the shop.

dude the stuff you make is dope asf keep it up
I imagine you in the shop pointing to all your appliances like Oprah. "You get a dust collector, you get a dust collector, EVERYONE GETS A DUST COLLECTOR".
i love watching people work on projects when i am indoors relaxing
this dude never ceases to amaze me!
Now you got me thinking. I may build a small one for my scroll saw. Great idea.
I have an old powermatic disc/belt sander that has a belt driven blower underneath/ a switch to toggle belt or disc and a filter bag. Came this way from the factory.
Get a Dust Deputy; I have one connected to my CNC router and love it. The DD bin will be full in a few weeks but the vacuum's filter and container are still clean and empty.
Just ran across your channel. Love the idea of decentralized dust collection. Much simpler and probably less power over time. Kepp broadcasting!!
Wonderful use of shop tools as always Mathew, thanks for the inspiration ...
I like the way you speed up your videos , if I have to watch someone on standard time drive in all the screws, tighten all the bolts etc. , I go on to the next video .
"I like the idea of a small dust collector so i added one to my kitchen"
Brilliant, Matthias. I think my big shop dust collector will soon become dedicated to just the cnc.
you are awesome Mathias. I really appreciate your methods of investigating stuff.
I've been doing something similar with those cheap little shop vacs + a cyclone/thien baffle. I like your solution better; more airflow, larger capacity and much quieter too!
That does make a lot of sense. A vacuum for each tool. That way if the vacuum on one tool breaks at least the others work.
I love how compact these are. Personally I think I'd like a huge dust collector with ductwork running to each machine in my shop someday, but think is certainly a good alternative.
Matt is the guy you want when designing aircraft systems..he sweats the details.
I started doing this a couple of years ago. no ductwork all over the place and a lot quieter. I put the little dust collectors in the cabinet under the machine.
I like your idea and it seems to be a quieter solution as well.
Loving this idea! And with your permission going to use it in my workshop too. The only problem I have is finding a good source for all the electrical parts.
Goodwill / Salvation Army type of stores is my thought
Those blowers are quite expensive new. I got mine used from a guy who installs furnaces and water heaters.
I had the same feelings re a whole shop dust collector vice individual dust collector at each power tool, particularly those which generate large volumes of dust. However my approach is to use small shop vacs connected to relay switch that has a built in time delay when stopping. It's a tad expensive but I don't have the resources to look for blowers at flea markets, garage sales and dumpsters. However Mathias' approach and design are very entertaining.
"man that's such a small box to be cramming such a big filter into" haha well played!
I like those square screw that you're using, no risk of striping
Very clean design/implementation.
For machines like sanders, scroll saws,... this seems to be a good solution. Better and less complicated than a pipe system for all of them together.
I love your precision
really good idea. As soon as you painted them green im hitting the like button :P
The secondary filter being clean makes perfect sense because as the first filter becomes more plugged it actually filters better but with less efficiency of air flow.
Very nice work. Very professionally done.
Also enjoy your FF editing when showing the labor (sawing, drilling, etc.). Makes for a very enjoyable watch. We can see how you did the work (laying out, transferring, etc.) without watching paint dry. (c;

For filter setups, you normally want to use a pre-filter (cheap, fairly coarse collection.) and then your fine filter (allergen or other fine/ high filtration filter) The logic is your fine filters are better quality/ more expensive and catch the small stuff the cheap/coarse filter missed. The cheap filters clog up with large stuff but keeps the large material off the fine filter. They can then be vacuumed or tossed. This is a more efficient and longer lasting design than just 2 fine filters in series or 1 coarse filter like that 3m was. (3M has a large array of different filtration qualities. But cheap filters for sawdust collection are probably best. Go with the good ones for your home and family.)
Great build and I like how well those pulled in the sawdust.
Although this video is over 4 years young, I do believe this concept (each tool having it's own dc) is the future.
Matthias, we use the same concept in automotive cnc machines. Keeping the mist collectors small and tied to 1 or 2 machines at most.
Well done, an elegant answer.
Really, really, really like these Matthias. Thank you.
I want your workshop!!! :D
Really interesting that the cheap filter outperforms the Filtrete one. You can make an even better one with a dedicated metal cabinet for the filter housing with a 5" thick filter. It has better filtration performance, and a larger surface area, meaning it can perform longer without having to be cleaned. These filters are for furnaces, and they are rated at MERV11 or MERV14 - the air cleaning capabilities are far higher than a bag filter or the thin furnace filters you are using. Of course, your filters appear to work just fine for a workshop, and thus are not an issue.
You are a legend, Thank you for providing us with all your videos on youtube people really underestimate how much goes into these videos, Thanks Matthias :)
HVAC duct guy here. By cutting open the shroud further, you didn’t increase total airflow (CFM). What you did do is decrease velocity (FPM) because you increased the internal volume without changing motor speed. And also introduced turbulence because the blades aren’t directing the airflow out their intended, engineered opening. Not that it creates any catastrophic failure, but you can be filtering much more particles per minute if you stick to the designed openings as closely as possible.
I had measured it and airflow did increase, though I remember only about 20 percent
Matthias Wandel what instrument did you use to measure the airflow? When doing measurements, you have to take things into consideration such as static pressure, velocity pressure, turbulence etc as part of the equation. Thanks for the reply
Very interesting I'm in need of dust control in my shop and like the idea of individual units for each machine
He is making dust to collect dust. Love him!
When I build my own Mini DCs they will have windows installed, so I can see at a glance if they need emptying/cleaning.
dust collectors are the superheroes of every workshop
Nicely done, tnx Mr. Wandel for sharing it!!!
Why were you in a hurry when you got the blower?
Did you find it before anybody lost it ;-)
I wasn't the one to extract it
