- On this week's show, I make my own version of some magnetic dust port fittings for my 4" dust collection hoses. This is a great addition for anyone who has a small shop and constantly needs to relocate their dust collection hoses.
I first saw this idea on Radek's workshop Instagram page and he has a ton of great stuff over there so if you are interested, you should check him out. You can find his Instagram here. / radeksworkshop
Also, if you are interested in the rare earth magnets that I used for this project, you can find them here. www.amazon.ca/gp/product/B089...

As always, thank you so much for taking the time to stop by the channel and check out today's episode of the show. It is very much appreciated.
I did this 5 years ago using toilet closet flanges, my system is a 5 inch system and I do have a couple of 4 inch hoses to smaller tools.
I embedded neodymium magnets using a forestner bit 1/2 dia. I found toilet closet flanges that fit on both 4 inch and 5 inches hoses.
I did have to flatten the matting surfaces as they had raised letters on the faces. To do this I taped 80 grit sand paper to a thick glass plate, then worked my way up to 220 grit. The system works great.😁🛫
Sounds like you've got it all figured out. Thanks for tuning in and for taking the time to chime in with your methods.
Great video! Very detailed! Thank you so much for taking the time to create it! I will be making some of these for sure!
Glad that you liked the show and the project. Thanks for tuning in and good luck on your fittings.
Great job Kenny, I think I will use this technique for my dust collection also.
Thanks for the kind words on the show. Good luck with your project and thanks for tuning in this week.
Kenny, clever idea. It sure makes changing the dust hose a lot easier and less frustrating. I never realizes that multiple stacked magnets would increase the strength as much as it does. Handy project.
Glad that you liked it Paul. If you think about it, a 1/2" thick magnet has more strength than a 1/4" magnet but if you only have 1/4" magnets, then joining two of them together would give the same strength as a 1/2" thick magnet of the same diameter. Thanks for tuning in to the show and taking the time to leave the kind words. It's appreciated.
You did well to point out the necessity of ascertaining adequate attraction before making up a lot of these halves. Thank you.
Glad that I was able to help Mark. Thanks for tuning in and for the kind words on the show.
Wow, what a brill idea!
Glad that you like it Paul. Thanks for tuning in to the show.
This is a great looking solution that I'm going to incorporate into my own system. Just finished building several blast gates, Katz-Moses style, so my DC system is shaping up~! Thanks Kenny~!
You're very welcome Andrew. Good luck with your dust collection build. Thanks for tuning in.
I live in Duluth, MN as you well know it gets very cold here and during the winter, I have used rags to plug the dryer vent because of the extremely cold air coming into the house, but I have never had a good way of disconnecting and reconnecting the dryer hose to the exterior vent. Your magnetic hose connector is the perfect solution! When not using the dryer plug the exterior pipe with rags. I have thought of using a blast gate but that would hold back the cold. Thank You!!!! This could also be done by a 3D printer to make the parts.
Glad that the video was useful to you Steven and that you were able to take something positive away from it. Thanks for tuning in.
Another home run!! Thanks Kenny
Glad that you liked it Lester. Thanks for tuning in to the show.
Thank you for the tutorial and pointers. Cheers 👍😎🇦🇺
The pleasure is all mine John. I'm glad that you liked it. Thanks for tuning in to the show.
Nice simple and inexpensive project. Thanks...I am going to use your design.
Glad that you like it Roger. Good luck with your project and thanks for tuning in to the show.
Great idea Kenny, never seen one like this before
Glad that you liked it William. Thanks for tuning in.
Thank you very much for mentioning me! I appreciate it and of course I subscribed!
Glad to have you as a subscriber. I hope that you will continue to enjoy content on the channel. Thanks for tuning in and for being supportive of the channel.
I love your videos. You’ve been very busy lately and hope that’s you enjoying retirement. Inspires me to get to it. Enjoyed the paper layout and using scroll for a template. About to paint a closet ledger board and install it.
I am far from retirement and still work a full time, 40+ hours a week job as an electrician. The TH-cam channel and the woodworking is just a hobby for me. Glad that you enjoy the show. Good luck on your projects and thanks for tuning in.
@@acutabove_woodworkings Oh sorry, thought you very recently did. Very busy indeed!
@@FearsomeWarrior No worries. I'm old but not THAT old. LOL
Great video. It should be noted that if you use one side all positive polarity and the other side all negative, and you are making more than just 1 set, they won't be fully compatible with each other. You have to keep them sorted in pairs. If you alternate pos and neg polarity as you go around the ring, then any ring will work with any other ring. Also, I'd recommend getting magnets from K&J Magnetics. They are a bit more expensive but have a great selection.
Thanks for chiming in with your suggestions and for tuning in to the show. Glad to hear that you liked it.
i've watched so many of these videos recently thinking the exact same point. I'm thinking that a profile would also mean you can reduce the number of magnets while also improving the seal
Nice one Kenny, Would be a good experiment for a 3D Printer - Include an extrusion for the hose to connect directly - Recesses for Magnets - PLA probably strong enough.
That would be a great idea Rob and would definitely work. I just don't have, or have access to, a 3d printer to make the flanges. If you try it, make sure to let me know how it works out. I'd love to see them. Thanks for tuning in to the show.
You can alternate the magnets in each part to allow any part to connect to any part
If that is your preferred method Marius, then it is perfect. Thanks for tuning in to the show and for chiming in with your suggestion.
@@acutabove_woodworkings we've been developing a product range for market (specifically the South African market), one component of which is magnetic quick connect ports. Challenges was yes - stronger magnets, as well as magnet polarities. Alternating the magnets made a big difference.
More info here (these are revision 1 designs and have vastly changed, but is similar in functioning)

I would have never thought of trying that. That is ingenious. Back to your pumpkin carving, You said that a scroll saw blade may be too flimsy for cutting. I found an old coping saw blade and tried that after shortening it. It seemed to work ok. Try one and see what you think. Enjoyed as always, take care!
I'm sure that the scroll saw blade would also work if I shortened it just a little. Thanks for the idea on the coping saw blade. Glad that you liked the dust collection idea. Thanks for tuning in to the show Michael.
now just think you are a korean and have to get this video out to the world wide audience!!
JSK nobu videos. i enjoy then so much.
Americans tend to talk themselves to death.
Hey a picture is worth a thousand words!! Is a video is worth a million words?
If you want a video that shows you the end product with a couple of 4X video clips in between to give you a partial explanation of what was done, then by all means, enjoy those show. I don't produce videos of "Look at what I made". I produce educational videos that actually explain and teach you how to make it. If you aren't interested in actually learning and would rather just see the final product in 3 minutes, then who am I to argue with you? Enjoy your shorter videos.
Thanks for tuning in to the show. For the record.......I'm not American.
@@acutabove_woodworkings there's one in every bunch. 🙄
I loved your video! I'm trying to figure out how to diy a magnavent for my dryer cause I can't afford to buy one 😂
@@SheilaSpencer1 I've sent you the pdf of the attachment. I think your idea for the dryer vent hose would work but I would suggest using stronger magnets than the ones that I used in this video. You don't want those connections coming apart. I'd be interested in how you make out with this project. Good luck with it and thanks for the kind words on the show.
I am going to make this project for my shop. I have two tools that have one hose and a block slide to shut off on all my tools. I think instead of using the slide blocks I will cut a piece of sheet metal to use for blocking off hoses as the slide blocks never completely shut off the vacuum because the wood shavings get jammed up in them.
Sounds like a good idea Tom. Let me know how it works out. Thanks for tuning in to the show.
Also instead of hose you can use fittings. See magport for details
Another good suggestion. Thanks for chiming in with it Kevin and for tuning in to the show.
I wish I had seen this before I bought all the dust right hose handle and the connection for all my machines.
I'm sure that the dust right connections are awesome Stephen. Thanks for tuning in to the show. It's very much appreciated.
Awesome content as always. All of my tools are 2.5 and me system is 4 inch I reduce at the tool. I have three drops I’m thinking this will help elieviate some clutter as I would move one hose around. You keep me thinking, which my wife says is hard to do!🤪
Glad that I can keep your mind active Bob. LOL. Good luck on your project and thanks for tuning in to the show.
Hey Kenny! Great video as always :)
I really liked this idea! I´m currently in the process of setting up my own little shop in my home, oh and guess what, I´m filming the whole process as well :)
But anyway, the dust collection is one of the things I´m the most "concerned" about. So this was really uplifting :)
One thought that came through my mind was, why not use a metal connector on the tool side? Do you think it would give enough bite? That way you would significantly reduce the amount magnets you have to purchase.
Have a good one and take care :)
Using a metal ring on one end would definitely give enough bite. It's a great idea Stefan. I'd love to see your shop setup when you are done. Be sure to send me a link to the video. Thanks for tuning in to the show and taking the time to chime in with your idea. It's a great one.
What a great idea. Although you didnt mention it I observed the dust small hose attached to your table saw fitting which I presume goes to your router? If this is true, could you describe this in more detail? Is there enough vaccum suction to work with the router without blanking off the table saw opening?
That small hose Woody goes to a top arm dust collection for the table saw. When using the blade guard and splitter, that hose works to clear all the sawdust from the top of the blade. It works really well. The router table has its own collection hookups. I hope this explains it for you. Thanks for tuning in to the show.
@@acutabove_woodworkings Ahh, yes. I didnt buy the overarm so didnt recognize it.
I don’t have a dust collection system, but my shop vac has so much suction that I cannot use it on my random orbital sander, it sucks it down to the table. And it pulls the sawdust out just fine from my saw and planer. It has a 2 1/2” connector. I use a 4” to 2 1/2” adapter. Also, trying to add the proper reducing adapters is a pain, or connecting to various tools because they have custom size connectors, like my Dewalt mitre saw. But I want to build this type of device, make it was to switch between power tools. So, not only does this all ease of use to move it around, but each connection can be an adapter. On the 2 1/2” hose piece, keep the outer dimensions the same, and make the hole equal to the hose, and attach it. Then make a piece for each tool, same outer dimensions, but make the hole match the connector of the power too. So now you have a system that allows you to move your hose around from one machine to another, and it is an instant adapter from one size connector to the other. One suggestion, you always want to keep the smaller hole of the connector on the bottom, as sawdust falls to the bottom machine duct connector.
Stacking magnets is fine, and sometimes you have to adjust like this, because you only have so much space between the hole and the edge of the connector.
Sounds like this idea will work just fine for your setup Scott. Good luck with your project. Thanks for tuning in and for taking the time to chime in with your suggestion. It's very much appreciated.
Hey Ken! There wasn’t a problem with the magnets at all, you were standing/ squatting too close with your magnetic personality! Thanks for the movie Ken!
That's pretty much what I thought too Frank but I didn't want to say that on camera. LOL. Thanks for tuning in to the show sir.
Nice Job, I was also considering a very light ring of silicone spread real thin on each side to serve as a gasket for a more airtight connection. You thoughts?
I would agree with you that there needs to be something there. I'm just not sure what. For higher output tools such as the thickness planer that has an internal blower fan the seal is not enough to keep the dust in the collector so I was thinking of a thin layer of foam to act as a gasket for that tool. All other tools seem to be just fine though as they don't have a high output of sawdust. I will be experimenting with several ideas and see what happens. I am sure that it will be reported back on one of my regular 6 month update shows. Thanks for tuning in Charles.
@@acutabove_woodworkings What if the magnets were mounted just below the surface instead of flush? Would the flat surfaces of the plates be "air tight"?
@@douglasruhs2344 I suppose they would be a little more "airtight" than they are now. I would think that the magnets would have to be a little stronger though in order to bridge any gap between them. Air space is a magnetism killer.
Great video. Definitely going to make some of these. Now if you can just figure out how to go from 4" to 2.5" I would greatly appreciate it. haha
I would think that making the hole smaller would work. If not, there are 2.5" connectors that could be adhered to the magnetic plate. I hope this helps a little. Thanks for tuning in David.
If, instead of going all North up on one, and all South up on the other, you alternate, N, S, N, S around, then any piece, will connect to any other piece, with at most a turn of one point.
That's a great idea Chad and while it may seem like a pain to go through all the trouble of figuring out the N/S configuration, it would go a long way to making all pieces compatible with each other. It's a great suggestion and I thank you for chiming in with it. Thanks for tuning in to the show.
Nice job
You can always buy stronger magnets! Then use only one in ring
That is definitely a possibility Kevin. Unfortunately, when this show was filmed, those were the only magnets I had. Thanks for tuning in and for chiming in with your suggestion.
Are the magnets slightly beneath the surface of the wood, slightly proud of the wood, or exactly even with the surface of the wood?
The magnets are level wit the surface of the wood Larson. I hope this helps. Thanks for tuning in,
@@acutabove_woodworkings Thanks.
Have you had any problems dropping the head of the hose and the magnets breaking?
I wasn't fond of the strength of the magnets during initial tests and that was the reason I increased the number of magnets in the hose head. I haven't had any issues of dropping the the head at all. As for the magnets breaking. To date, I haven't broken a single magnet. The rare earth magnets are fragile and if you let them slam together, they will shatter so it's important to try and ease them into the seating instead of just letting them click together harshly. I hope this helps. Thanks for tuning in Jeff.
The shear (lateral) strength of magnets is extremely poor when they are fighting gravity, ie, they slide off of each other without much resistance. The pull or repel (direct) strength is usually about 10x more. This is evident when you try to break magnets apart - it is easier to slide them off then to pull them apart.
So if you had a wider hexagon collar piece that housed the dust hose like in male/female pipe fittings, the hose would need to break the pull strength before it could slide laterally (down) off the magnet. If you were to hang the hose vertically the magnets would be doing "pull" work directly. But when fixing to your table saw etc horizontally they are doing "shear" work and relying on their lateral strength.
This is actually a great idea and I appreciate you chiming in with it. It wouldn't be hard to modify the one collection plate on the dust collector to accommodate a flange to simulate the female part of the connector. Love it. Thanks for tuning in and for taking the time to chime in with you suggestion.
Did you increase the size of the flange on the hose? I’ll be making some of these soon!
The holes for the flanges are all measured to fit the outside diameter of the dust collection hoses. The flanges are all the same size. I hope this helps. Thanks for tuning in to the show.
@@acutabove_woodworkings I was wondering if you made it thicker to accommodate the 5 magnets?
@@kevinmccarthy8670 No, the magnets are thin enough to accommodate several. I could have put another one in each hole if I wanted to. These magnets are only 1/8" thick.
I’m going to prototype a similar design using a hexagon and 3D printing the connectors instead of using wood. Time to fire up SolidWorks.
I have recently updated this show on my 6 month update series. The magnetic dust collection fittings were retired. While I know the satisfaction of designing your own 3D printed items, I was able to find a set on thingiverse and I have printed and tested them and they are fantastic. If you are interested, you can find them here www.thingiverse.com/thing:5358837
I hope this helps. Thanks for tuning in to the show.
@@acutabove_woodworkings Thanks so much for the reply, Kenny. They look great, though I'm wondering about their apparent bulkiness, both for handling and for material expenditure. I'll try to find your 6 month update.

@@acutabove_woodworkings Thanks much!
Curious...have you measured the force required to separate two of your magnetic flanges? If so, what is it?
I can honestly say that I've never measured that Trent. Sorry about that. Thanks for tuning in.
@@acutabove_woodworkings Have you ever had one come loose when you did not want it to?
@@trentpaulk4966 I had it happen a couple of times on my table saw. I fixed the issue by adding a few more magnets and I didn't have to problem again. I hope this helps.
@@acutabove_woodworkings thank you!
@@trentpaulk4966 The fitting on my table saw came off a few times but I fixed that issue by adding a few more magnets to the table saw fitting. I haven't had the problem since.
I found magnets are not strong enough and with even slight pull the hoses come off!
I had the same issue and that is why I doubled up on the magnets in the fittings. It corrected the problem and the fittings click in with no issues now. I hope this helps. Thanks for tuning in and taking the time to leave your comment.
@@acutabove_woodworkings Thanks. Much appreciated.
Why not use some thumbtacks to secure the template to the wood, then use the pattern with a flush cut bit ? Just router the whole thing, remove the thumb tacks and you have the center of the magnet mounts marked.
As with anything Dominic, there is always more than one method and the methods that I show here on the channel are merely suggestions. It sounds like your idea would work just fine. Thanks for tuning in to the show and for taking the time to chime in with your suggestion.
👍👍 JimE
Glad that you liked it Jim. Thanks for tuning in to the show.
What dust collector you use
I have been using this one for years and it has served me well. www.busybeetools.com/products/dust-collector-1hp-570cfm-1-mic-bag-csa-ct053.html
I hope this helps. Thanks for tuning in to the show Luke
could you epoxy to secure the fitting
Of course. The method that I showed here on the program is just one of many. You can use whatever method you like. I'm pretty sure that epoxy would work just fine. It would be a lot more expensive than silicone but would work, none the less. I hope this helps Ray. Thanks for tuning in to the show.
Great video Kenny, i'm surprised an idea like this hasn't been picked up by a big company. I have seen the Rockler Dust Right 4" Quick Change Handle (blimey that's a mouth full) but not something involving magnets. Well Done.
Stay Safe,

There's a similar idea done for dryer vent hoses to make them easier to connect in tight spaces.
@@stevenlarson6125 I actually mention those in the first 35 seconds of the show. LOL. Thanks for tuning in and taking the time to chime in with your comment. It's appreciated.
@@acutabove_woodworkings Oops. I was at work and had to keep doing "work things". Had to watch twice. Missed it first time.
@@stevenlarson6125 No worries. I'm flattered to know that I'm more important than work. LOL.
Great video, I'm starting to set up my hobby shop. Do you still have the plans for this? I sent you an email yesterday. Not sure if you are still giving out the drawing.
Sent out the email tonight James. Sorry about the delay. The TH-cam thing is just a hobby for me and with my full time job in the real world, it sometimes takes me a little longer to reply. Good luck with your dust collection. Thanks for tuning in to the show. For the record, any pattern that I offer on the show, can be downloaded for free from my website. Just visit acutabovewoodworkings.com and click on the free patterns section. I hope this helps.
Just curious, how are these holding up a year later?
Still going strong. I haven't cracked or broken any of the magnets as of yet so that's a good thing. I will say that for the planer, that has a fan that ejects the dust as well, I actually place a wrap of electrical tape around the joint because it isn't a sealed joint and the dust likes to blow out of the small gap. Other than that, they are still working extremely well and I still use them with every shop visit. Every tool I have that has a 4" dust port has been hooked up with this system since I made it. If I had it back, I would have used strong magnets but other than that, I'm still happy with it. I hope this helps. Thanks for tuning in.
@@acutabove_woodworkings appreciate the feedback. Going to try it out.
Another good video. However, for many of us who don't have a scroll saw, how do you suggest we achieve the accuracy needed to get the tight fit needed, particularly with the smaller hose connections?
You would always use a bandsaw Clwyd and then glue the kerf back together. If gluing the kerf back together isn't something that you'd want to do, cut two 1/4" thick pieces and laminate them together with the bandsaw kerfs offset to give it more strength. Alternatively, there is always the table saw and then a holesaw for the hole. Or a hand saw and a coping saw for the hole. As with anything on my show, there is always more than one way to do it. I hope this helps. Thanks for tuning in to the show.
Why not just put magnets on one side and a sheet metal flange on the other? It’s ferrous and should allow the magnets to adhere just fine.
There's noting wrong with your suggestion and it would work just fine. If that is the method that works for you, then by all means, you should make them using that method. The procedures and methods that I demonstrate on my show are merely a suggestion and there's always a different way to do it. Thanks for tuning in to the show and chiming in with your suggestion. It's very much appreciated.
