Table Saw Overarm Dust Collection, Shop Built x 2

Table Saw Overarm Dust Collection, Shop Built x 2

Double Taper Sanding Disc:

In this video I build a pair of over arm dust collectors. I built the first one as an experiment, I liked it so much I built the second. I worked to improve the design the second time around. I am happy with the end result, both collect almost all the dust created on the top side of the blade. I hope you find this build interesting. Feel free to ask questions.

    awesome build. do you think adding that brush material around it would improve it more?

  2. justtestingonce on April 15, 2022 at 6:07 pm

    This solution is screaming out for metal tubing.

  3. Marcus Caius on April 15, 2022 at 6:08 pm

    Mike, do you think it would work well with JessEm Clear-Cut Table Saw Stock Guides?

  4. Rob C on April 15, 2022 at 6:09 pm

    I like the thin design of the shroud. I may have to copy that when I rebuild my current setup.

  5. Omar Flores on April 15, 2022 at 6:11 pm

    Great project!!! Question.. I’m in the market for a dust collection system. I’ve thought about building something similar. My question is, when you run dust collection thru the top do you also run another hose they the bottom or is the top one enough? I works out of a very small shop and if I can run just one line they the top I could just switch it from tool to tool. TIA

    Thank you very much for sharing these very useful ideas with us

  7. Gregory Lattanzi on April 15, 2022 at 6:13 pm

    Just found your channel. Thanks. Do you have plans for making this? Thanks.

  8. Martin Dornhofer on April 15, 2022 at 6:13 pm

    Cool Design, Dude….💪👍

  9. Dustin Allman on April 15, 2022 at 6:13 pm

    What is that awesome yellow "feather board" tool you have on your table saw at 9:14?

  10. Gerald Schmidt on April 15, 2022 at 6:14 pm

    i like

  11. 69kaveman on April 15, 2022 at 6:14 pm

    Nice build!

  12. David Attenberg on April 15, 2022 at 6:15 pm

    Mike, is there a way I can get in contact with you? I might have something you, as a tool head, maybe interested in.

  13. Michael Baker on April 15, 2022 at 6:16 pm

    k-nobs are good, if you k-now what you’re doing, and you don’t hit any k-nots.

  14. Павел Кокарев on April 15, 2022 at 6:17 pm

    Отличная идея, спасибо!

  15. Flatdog Sound & Light on April 15, 2022 at 6:19 pm

    Great job the only thing I will change is the with so I can use it when the blade is at an angle !

  16. bb foto on April 15, 2022 at 6:19 pm

    @Mike Farrington
    Great design & build, Mike!

    One thing I’ve found in my experiments with these is that it works much better if the hose and air suction approaches the blade a lot more from the Front…so that the hood would be angled opposite to yours, i.e. from front to back.

    Obviously this would be more obtrusive and "in your face", but because of the rotational direction, the blade naturally throws 85% of the dust forward towards where you are standing, and having the hose in front of the blade enhances the natural air flow direction instead of having to fight against it…

    The forward air velocity (and therefore dust) shooting towards your belly off of the blade is quite strong.

    Also, reducing the hose diameter to 3" or even 2.5" at the last bit helps for it to be less obtrusive and also increases the air VELOCITY and concentrates it to a narrower area in front of the blade where most of the dust is headed.

    In addition, angling the hood into the left side of the blade or into the saw table from the outer left side towards the right increases the collection of the dust coming off the left side of the blade. Very little dust is thrown straight up, or backwards, or to the RIGHT side of the blade.

    I’d like to see you try a v2.1 to compare results. If you can come up with a "low-profile" and compact design that isn’t too obstructive, I think you’ll notice a significant improvement. 😉


    I’m in need of a new Cordless Drill/Driver Set and I like the more Compact & Lightweight 12V cordless options for 90% of drilling & screw assembly duties.

    Would you buy your *BOSCH 12V FlexiClick Drill/Drivers* AGAIN if yours were lost or stolen???

    I see that you’ve Linked to the Makita 18V LXT Brushless combo set and right now I am only invested into that Makita 18V LXT battery & tool system as well, but I don’t mind adding one other battery ecosystem. I haven’t been all that impressed with Makita’s "Sub-Compact" offerings, so???

    THANKS! LOVE your channel and what you do and appreciate you sharing it with us!

    Don’t forget the riving knife – couldn’t see it on your table saw

  18. Made by M.E. on April 15, 2022 at 6:22 pm

    nice work, looks like the dust collection works very good. I have to build one for myselft, there are so much different solutions🙄

  19. Phil Copeland on April 15, 2022 at 6:23 pm

    Your ingenuity and cerebral flexibility never ceases to impress me, Mike. Well done. One thing that bothers me is seeing a hoodie with its strings hanging down being worn when using electric tools. I’d hate to see you with that nice beard receiving an unplanned trim.

  20. Andrew Horton on April 15, 2022 at 6:24 pm

    Mike, incredible build. I’ve been searching and this is the one i’ll build. I’m curious, when you glued the arms, did you get glue-spurt on the inside, and if so, how did you deal with it? thanks for a great build and video. Great outdoor shots too!!

  21. Greg OHare on April 15, 2022 at 6:25 pm

    When I saw the picture in your thumbnail (in the suggested video column) I thought that is the craziest dust arm yet. There are so many table saw dust arms videos now. Then after ignoring your video for over a week, I thought I would check it out. For me, as it turns out, yours is the best. Some look very slick but have obvious drawbacks, such as lack of rigidity and to large of a guard that inhibits use. The others often put the boom were it will obstruct the operator. Yours looks perfect. Think yours is really spot on. Thank you for sharing your great design. BTW, all that noted, did you think about using the boom and vertical section as your dust tube? Just a thought, but still yours is just a great design. Thanks again!

  22. Gyras on April 15, 2022 at 6:27 pm

    God I envy these expensive wood workers. I don’t have enough amperage in my shop to run both my saw and a vac so I just put a 90 degree on my outlet to keep it going downwards. After a good cutting session, I am COVERED in saw dust.

  23. Tim Rucci on April 15, 2022 at 6:29 pm

    Inspired by your design, I build something similar myself and it works really well. Attempting to solve the edge cut issue, I used a small cutoff from one of the sliding support arms, that was about 5 inches long after I cut the assembly down to final size. I cut this "off-cut" in half, producing two 90-degree corners about 5 inches tall. I set one of the corner pieces just in front of the plexiglass enclosure, and slightly to the left of the axis of the saw blade. This would allow the piece being cut to slide past it, within a quarter inch or so. The sawdust that would normally shoot toward me on an edge cut, instead deflects off the inside corner and upward, but settling back down near the plexiglass enclosure, where it was immediately sucked up with the rest of the dust. It’s a very easy temporary fix. I ordered a door sweep with a brush bottom that I plan to experiment with, attaching it to the bottom of the plexiglass enclosure which should allow wood to pass through the brush, and then hopefully form a shield after the board passes. If that works, I will probalby attach it to the bottom of the plexiglass.

  24. Matthew Trykall on April 15, 2022 at 6:30 pm

    Adding some bristle material at the bottom edge of the plexiglass secured with rivets, may improve dust collection further. Similar to the bristle material on your CNC dust shroud.

  25. guitarchitectural on April 15, 2022 at 6:31 pm

    Did you consider putting a brush/shoe so that it would capture skim cuts also? Looks like a great build and a good upgrade from my sawstop blade guard!

  26. Norm on April 15, 2022 at 6:33 pm

    Nice build and concept.

  27. Scott Ross on April 15, 2022 at 6:33 pm

    Very clever ideas! Nicely done video!

  28. globe345345 on April 15, 2022 at 6:33 pm

    Nice build! How much space did you leave in the telescoping joints (between the outside sleeve and the inside sleeve)? Is there a good rule of thumb? I find it hard to find the balance between free motion and snug fit.

  29. TomsDreamshop Worx on April 15, 2022 at 6:34 pm

    Just watched a bunch of your shop videos and hit the subscribe button. I am enjoying your workmanship and humor. I didn’t read every single one of your almost 400 comments, but I glanced and didn’t see anyone talk about the Plexiglass you used for your guards. Plexiglass is an acrylic which can shatter very easily. Lexan is polycarbonate which is what they make safety glasses and bullet proof glass items. It’s a much safer material to use around the blade in case something happens and the acrylic shatters where polycarbonate will just bend.

  30. Driftless Joinery on April 15, 2022 at 6:34 pm

    I’m quite late to this party….the dip is looking a bit questionable…..but, I’m brave.
    Thank you for building this. I bought one of those new tricky saws about a year ago and chose not to add the overarm dust collection but assumed I’d build one but still haven’t. This is a good push to do so. I built one that hung from the ceiling back in the olden days and hated that thing the first day of use. I’ve used the old Beisemeyer ones also and the one thing I really liked about it was a clipboard holder and my coffee cup cozy installed on the horizontal bar as well as a mini white board so we could write nasty notes at one another… dusty times before the internets. Again….good stuff Mike.

  31. Butch Ford on April 15, 2022 at 6:35 pm

    Nice build. If you put broom like sweepers around the perimeter like on CNC machines you might capture more dust.

  32. Martin fahy on April 15, 2022 at 6:37 pm

    Great job Mike, I’ll have to do my own

  33. dyoooooooooon on April 15, 2022 at 6:37 pm

    Wow, this is very nice. Makes me want to build one myself. I guess the only time you won’t be able to use is when you are ripping something thin and you have no room for push stick, right?

  34. George Katechis on April 15, 2022 at 6:38 pm

    thats awesome! question. Is there a reason you painted some of your tools? Thought it looked pretty cool, but i’m too afraid of trying and fucking it up

  35. TrailTrackers on April 15, 2022 at 6:42 pm

    Hey Mike… If you can find the time, please do a video where you just talk about your paint booth area? I wouldn’t mind knowing what sprayer you use and why. If you had "unlimited" money what sprayer system would you purchase? And why. Thanks in advance.

  36. Mitzy Crafts with Friends on April 15, 2022 at 6:42 pm

    Very nice. I bought one that was a heavy pipe and it was so difficult to mount. I wish I had seen yours first. I am curious why you didn’t put the bristles at the bottom of your guard to allow more dust to be collected?

  37. Nathan Beazer on April 15, 2022 at 6:43 pm

    Super clean and tidy and very practical piece of equipment no doubt about that at all but I have a challenge for you let’s see you make something without the table saw. I’m based in the UK and with the exception of hobbyists he watch a lot of YouTube so they get these bad habits from you guys in America and Canada we only use table saws for rip cuts what they were designed for everything else that you would use it for we do with the purpose-built equipment which you have writers and the Bansal please don’t think I’m having a dig I just think it’s incredibly dangerous and every time I see you guys hanging your head over the top of a blade it makes me cringed not to mention the rest you take with your fingers so So see if you can make us something simple a small humidor or a jewellery box but don’t use the table saw The bandsaw you have is way more capable and safer that you give it credit you just need to learn how to use it and equip yourself with the correct blades keep up the good work I do like your channel even though I have to look away occasionally👊💚

  38. ak2007r6 on April 15, 2022 at 6:46 pm

    Looks great. I recently purchased a Shark Guard and dust collection setup for my saw and kinda wish I had just done something like this. This looks more versatile

  39. Pletivo Bg on April 15, 2022 at 6:47 pm

    Thanks for sharing Mike! Tomorrow I am going to build a copy of your idea . Thank you!

  40. Zifnab on April 15, 2022 at 6:49 pm

    great project! I wonder , if you beefed up the wooden tubes could you run the dust collection through the arm and only have a short section of hose at the end?

  41. Elliot Gesang on April 15, 2022 at 6:53 pm

    Great job and excellent video. I presently have a 4 inch vacuum hose to the bottom of the table saw and I want to add this vacuum port to the top just like you did. So should I use a second gate with the second hose or what I put a tee in the hose and have it vacuuming from the top and the bottom. just wonder what you think about that or how you did that in your shop.

  42. William Weatherall on April 15, 2022 at 6:56 pm

    A year later, how are you feeling about them and would you make any changes?

    I really like your design but I thought I’d ask your advice before committing the hours to building them.

  43. John Colgan on April 15, 2022 at 6:58 pm

    I was thinking at the start that you were going to double up on structure function, use the sliding boxes to be the dust collector tubing. The reduction in area would have increased the suction & velocity of air movement, until I saw you plug the end … Ah well, an overenthusiastic overengineered thought on my part.
    Great build. I take it the saw didn’t have a dust collector when you bought it?

  44. Alexander Timofeev on April 15, 2022 at 7:01 pm

    I made the same system for dust collecting. It works great. Thanks Mike.

  45. Simon Babl on April 15, 2022 at 7:01 pm

    I have copied the design and it’s great works 🙂

  46. david carroll on April 15, 2022 at 7:03 pm

    Hi Mike – what’s the sliding table saw you use and would you recommend it? I do quite similar joinery to you and I’m about to pull the trigger and actually get one , I’ve been using a cabinet saw for years and looking forward to adding a slider to the workshop. Great builds keep up the good work 👍

  47. plunder1956 on April 15, 2022 at 7:03 pm

    Where is the landscape you feature. You do get some amazing sky-scapes I was trying to work it out, but failed.
    Nice arms. I was just wondering how they would work in tubular metal. The downside being it might resonate and ring.

  48. Steve cuthbert on April 15, 2022 at 7:03 pm

    I enjoy watching and listening to your videos. Your son has good concentration.

  49. Gyras on April 15, 2022 at 7:05 pm

    Did he just use Loctite on the outside of a screw? I was unaware that the blue Loctite had any wicking function.

  50. bobbg on April 15, 2022 at 7:05 pm

    I wonder if you could have used pipe as the stand and not had to use 4" hose . I see your Apprentice is getting really good with the drill it might be time to move him up to shop sweep and give him upper arm strength.
    No seriously Its great you ahve your son out in the shop with you, I was helping my dad when I was 7 running his table saw holding plywood as he feed it past the blade. That saw was a sears craftsmen table top one from the early 60’s he bought when I was less then 3 years old. I went with to buy it. That saw didn’t have a riving knife or splinter, and it could kick back. So I must have earned his trust holding the end of a 4×8 sheet of plywood. Me I wouldn’t trust my 37 year old to hold my lunch pale
    My kids don’t do this kind of work. And they didn’t learn it in school. Someone has to learn this tradition. Or the art form going to die out. I’ll bet he makes really good money doing it too. Not like when I was young carpenters were a dime a doz.
    All the trades are in dire need of fresh workers. You can watch almost any show like This old house or Holmes on homes they are begging for young people to get into the field. Beats flipping a hamburger. Can can pay 6 figures for some of hoses jobs without collage.
    Go look up pay scale for Electrical, plumbing, hvac and carpenter. And the related fields.
