- I have a 2000 sq ft shop, 1000 on each of two levels. I have a 24" bandsaw upstairs and two 15" downstairs. Dust collection is critical both from a health perspective and a productivity perspective. I came up with a simple and inexpensive way to better control the fine dust produced from the bandsaw. It will have to be adapted to each saw but the principle remains the same regardless of the brand. Hope this helps you.

I just made one of these for my Jet JWBS-14DX. It has the Carter guides and the lower thrust bearing made for a very tight fit. I embedded magnets in a block of 3" x 3" x 1/2" ply to hold the tube in place. Rob put a cap on the end of his tube and I taped one end of one of mine shut. I tried some cuts with and without the far end taped shut and the open-ended one significantly outperformed the taped one. I think it's because the sawdust collects in the gullets and there is high-velocity air blowing 90° across the gullets which clears them out more efficiently. If the only source of air is from the throat, the air is pulled parallel to the gullets. Anyway, I'm delighted with the performance of this little mod.
I am amazed as to how Master Craftsman like yourself have the time and patience to share important information to us on our Wood Working journey. I am a Timsmith and I truely appreciate your advise and help. I share with my students all that you and other Master Craftsman take time to share. Thank you.
Hey Rob, I just added this to my old Rockwell 14" along with a 4" port cut into the lower cover. Worked great. Thanks for sharing.
I know this video is quite old but it sure has helped me a lot with shop dust collection. Not only was I able to apply the techniques to my Harbor Freight 14" it gave me ideas and helped to solve the miter saw mess. No more dreading to use the miter saw.😀
Rob
this is great, absolutely ingenious, to catch the dust at the source.
thanks for this
Just finished a week of bandsawing and battling with the dust, wish you posted this last week 😊 thanks for sharing Rob
Great way to get the job done. I will be applying it to my old 14" Delta that makes such a mess. Velocity at the source. So simple. What you have done looks to be a better way of keeping the lower cabinet clean. Thanks for showing us all a better way.
What a really simple solution, thank you for putting this up.
Amazing how the simplest solutions are the most effective. Why can't manufacturers get these ideas? That is brilliant. Just bought a 17 in band saw and I am definitely going to use this idea. Thank you!
Mostly because the tool designers probably don't have much or any experience with actualy using the products they design. That's why the end user usually is the one to develope something innovative to work around any design flaws.
Great idea! I'm glad I found this video. The factory dust port on my Jet 14 bandsaw is not working well at all.
Beautiful idea. And thank you for sharing.
I made this for my bandsaw. Genius! Works like a charm Rob. Thanks.
So simple, fantastic.
I will for sure do this too.
This old video needs a bump 😀
Excellent solutions, thank you kindly for sharing!
That's pretty brilliant, way better than the factory ports placed in inefficient locations.
Great job! Thanks ! Going to make one for my band saw.
great solution!
simple,cheap and effective.
I subscribed. thanks
Simple and effective. Congratulations.
Great idea for dust collection.
Rob, worked great for my little 10" power-Kraft. Used 3/4"pvc, ducted down to base, then elbowed 90. where I connect to shopvac. On end of PVC, added half of pvc union fitting,. The union threads fit snuggly into a 1-1/2" rubber cap that holds onto shopvac nozzle. Also the Union has matching inset that shopvac nozzle nests into. No dust! Thanks Again.
Awesome idea. Thank you!
Thanks very much for sharing , I will make this for my Rikon 14" - 10 -326. Also the Oneida on the Fein is nicely tricked out ,have to try to work that on my Festool Shop Vac.
thanks for sharing Rob ,great idea , have this on my band saw a while and its ok better than the factory collection, but yours is a lot more efficient and will try it with out a cap to see if its better collection
I keep returning to this video to figure out how to collect more dust. It's time to actually make it. Thanks for posting this video.
Thanks for the video. FYI, I use a heat gun to taper or flair PVC to make my own adapters. Lots of TH-cam videos on how to make your own custom adapters.
Thank you! This is a great way to capture the dust closest to where it's made. I will use it, modulo a small adaptation which will solve the tilting-table problem.
Rob Cosman the plan is very similar: bring the pvc pipe in from behind instead of beside the saw. otherwise same idea.
excellent solution. setup simular dust collection on my Jet bansaw with 1 1/2 abs mounted on the bottom wheel door. Have to remove the table angle hand nut to open the door now, as it's in way. But hey, no reason to go in there very often any more. nothing to clean. Works great!
Excellent Idea, Thank you for sharing your time and beta test materials. As others have said an open end may increase velocity. Also drilling some holes in the Table insert / throat plate may increase performance
Very helpful. Thanks for posting....
Found you from the shopbuilt collab vid and I am SO glad you guys did that together! This is awesome! Would LOVE to see your other dust collection innovations as well!!
+Rob Cosman Super Awesome!! Can't thank you enough for the GREAT content it has furthered me deeper and shortened my learning curve a ton! Appreciate ya!
great idea Rob!
Thanks Rob, even though I don't own a bandsaw, the idea can be adapted to other power tools. BTW, love your line of hand tools (planes, saws)...one day.
Very nice. Thank you for the video!
I did this to my band saw and it works really well.
Question, You used just double sided tape to hold it all up? Thanks
This helped me a lot thanks
Man that's so simple its Brilliant!!!
This solution works efficiently at capturing 95% of the fine sawdust!
I have a general, and I'm very happy with it. HOWEVER, for some bizarre reason, they put a collection "port" on the door down to the left as you're standing in front of the machine. It sort of works. Sort of. I'll either go with some sort of magnetic removable box like structure under the table, or this idea of a straight pipe. Thanks for taking the time for the demo. Cheers.
thanks rob on the case straight away
Great tip!
Very timely for me. I've been procrastinating and I'm now looking at a pile of logs to be cut into turning blanks. I'll do this mod first and save myself a ton of dust all over the shop. Montana Wood Art.
This design follows the first principle of DC: get close with the air inlet. Second thing is sheer velocity at the hose inlet. The combo of close and "fast" will tend to pick off the dust. Making sure the cabinet will allow air IN is equal to arranging for air OUT. Getting exhaust on TOP of the table is also important; not all the dust goes down the rabbit hole.
going to make one nice idea!
I tried this works great thanks I have a Grizzly GO555x and the dust port that it come with didn't really catch must dust. I used a piece of 1" pic 45 deg bend bolted it to the base and did not cap the end. it catches all the dust!!
Good solution. I never tilt my table either. I don’t think I’ve ever once actually tilted it for anything.
As far the table top dust... You could use 2'L x 1/2" OD PVC pipe and cut on the table saw slot that is about 1/4" wide in the direction of the pipe. Add the pipe to end of the table. Connect pipe to your vacuum and it will pick up some of your table dust as the wood is being pushed. We have cardboard cut/folding machine and has a few of those around cutting areas for the dust ,it works like a champ.
Thanks. I've been wanting to add dust collection to my 14" Yates American bandsaw. As these aren't the most common saws I've hesitated to cut a dust port. Looks like this approach could be more effective without mutilating the saw.
Brilliant!
You cannot tilt the table with it attached because it would cause the blade to bend unless you widen the blade slot. I agree with the others that you should remove the cap to allow the air to enter from the opposite end to maximize air flow.
Some one mentioned this to me as a possible solution to a clip I did 'Bandsaw dust ports do not suck'... Hmm, it may have possibilities. Mostly I cut wet bowl blanks and rip some standing on end so get long shavings. First thought is that with my wet shavings they would still go through the PVC pipe. Wonder if the PVC could be cut at a 45 degree angle rather than at 90 degrees so you can tip the table, and that would give some more room. I have a 3 hp Oneida system with a 5 inch hose. I put a end boot I think they call it, a slotted vent in the bottom of the door in my Laguna 16HD. There were a couple of other solutions that came up, but for sure the cabinets are not designed to pick up anything other than fine dust, and not the wet stuff I cut.
robo hippy
I am thinking too that when sawing, I use a 3 tpi blade on my little saw, and a teeth at 3/4 inch apart on my big blade. That is probably part of the problem as well, but the bandsaw is not designed with dust and shaving collection in mind...
Ingenious!
thank you
Simple and effective. Thanks for troubling to show us.
Nice solution. Have you considered not capping the end of the pvc? It seems counterintuitive but it would allow for the maximum CFM of airflow, with the greatest air velocity to grab the dust as it enters the chamber. I experimented with different dust collection setups on my different band saws and found that the ones that were too restrictive created too much negative pressure and not enough airflow. They' still would capture dust but nas as effectively as when I created a high velocity/high cfm cross draft situation to maximized air movement. I bumped up to a 2.5" hose on my shopvac which also helped keep cfm's high as well. Curious to see if that would improve your setup. Thanks for sharing!
What was the result?
Actually if you Install small cone style it will magnify suction in this application
Here is example /idea
physics.stackexchange.com/questions/244635/are-eductors-working-on-the-bernoulli-principle/249634
@@bfflorida2311 Interesting worth a read
Bernoulli principle does not magnify suction. The effect makes it possible to create conditions where positive pressure flow can create a little bit of suction on the side . This is how gas burners/torches work, the light suction pulls in a little air to mix with the gas. It will not help you with dust collection when your airflow is already coming from a vacuum. You already started with 100% vacuum - you don't need to convert it. Any conversion is just lost efficiency. What the OP is describing is likely a result of his dust collector's power band / optimal operating conditions. It can't generate enough negative pressure to overcome the restriction. If he had a higher horsepower motor he might see better results with an end cap, because the vacuum would be able to suck all that air from the smaller focused opening at high velocity. It *could* also have to do with the direction of flow... by forcing air directly through the gullets which are compacted with sawdust. But this would surprise me since the flow is likely already very turbulent within the shroud.
i knew there is a reason i check out these videos lol. i may well try this as soon as i get a bit of time to play. whilst my dust collection isn't to bad on the bandsaw it could definitely be better as i am mainly using rimu which tastes foul and really isn't good for you
Sounds like a good solution for dry wood, or composite materials but not to sure for wet stringy wood like what turners generate when roughing out bowl blanks?
Nice and thank you!!!'
cut the pipe underneath short and install a 45 deg. elbow to connect the vac hose to. That way you could get the table slant to what ever you need.
With 3D printing being much more mainstream you can have someone 3D print an adapter for the vacuum hose to the piping, I did the same when building my dust collector
Hey Rob, nice video... I was wondering what you did for your 20 inch Delta since the lower guides are up high and the approach is at a 45 degree angle. I have just finished re conditioning my 20 inch 1948 Crescent and I would like to get the dust collection right.
If you place the dust collection pipe on the left or right side, instead of the front, you'll be able to tilt the band saw table.
Very good. Wish this would fit on my 18" Jet though. The lower bearings are up too close to the table for a pipe to fit into. Oh well. Liked the vid though.
Rob,
Have you seen Shopsmith bandsaws? The later version of their bandsaw has a 2-1/2 inch dust port on the cover that's located 90 degrees from where yours are mounted. Have you considered a similar solution for your saws? Locating the port to the side would allow your tables to tilt without obstruction.
Thanks for a great idea. One question: is there a hole in the wooden block going into the PVC ? Or is there just the slot ?
Exact question I was about to ask…almost verbatim!
Anyone know?
Thanks for a great idea!
Given that the dust is travelling down the way, would it help to use a 45degree elbow pipe instead of the straight pipe? Like this shape _/ but up the other way! That way it would allow the table to tilt too. I know I can buy a silicon moulded (laminated) one in the UK for about £15 (CAD25), I assume you can get similar over there and probably a less expensive option too. I'll be using this idea when I eventually get my bandsaw though, it's well thought out,
Question, You used just double sided tape to hold it all up? Thanks
How do you like your Rousseau
5000 for your miter saw, do you have it hooked to a dust collector
Yes, velocity is important -- I’ve got a smaller (14bx 2 1/2hp) Laguna with 2 4” dc ports - think I’ll plug them and go with your solution! Actually may not need to plug anything. Haven’t carefully looked at clearance but should be able to adapt to it’s configuration - probably more like your 18” Laguna.
Let me know how it comes out
Me too!
Haven't figured out to post you a couple of pics.
Because you have now figured out how to capture bandsaw dust at the source, Festool will have to invent a portable yet extremely useful bandsaw
what brand of bandsaw is that ? I tried to search for it online and had no such luck finding any information on it...I love the dust collector design sometimes the simplest design is most effective.
A very nice solution. How about embedding magnets instead of double stick tape
Rob Cosman Too Right
hey im a new sub brian sent me!
You can make an adapter for the PVC by turning a wood block to thhe size needed for the hose and then heat the PVC with a heat gun or torch and force the wood plug in to stretch the PVC then let it coool and you will have the perfect adapter.
Thanks Jim, I will try that.
noticed your vacuum has a cyclone with a bucket over a thien baffle over the vacuum... that would be interesting to have a video about it and explain the concept... why two?
Stelios Stavrinides don't think that is a thien baffle. I think it is just a mount to hold the bucket above the shop vac.
Does that complicate changing blades?
Good question!
It's funny how an 'experimental' setup often becomes 'permanent', isn't it? That said, I wonder why manufacturers have not addressed this issue yet. It's not just a nuisance, it's a health issue.
Well, since now people are much more aware of the potential hazards of sawdust, as well as general shop safety and cleanliness, I think this would be a selling feature.
Gotta little bit of snipe there @8:50
Who else came here from Shop built?
me, instant subcribe
Perhaps they will do some more collabs in the future.
Angel Luis Trinidad Me!
I did!
Me too, can't believe I haven't noticed this channel before
Nothing that cannot be fixed by duct tape
Too smart for youtube. Who are you?
