Dude, I like your idea. I sent you an email from Eli so you can read my thoughts
I apologize for being wordy. I am a UA-cam fan of yours. I am writing this to several presenters.
About 60 years ago, I took high school woodshop. Thereafter, I learned a few basic things from my grandfather and father. Over the following 20+ years, I had neither the money nor the space to do any woodworking. About 25 years ago, some tools were passed on to my by parents, so I took over my garage, but my skill was rudimentary; the things I created were crude and imprecise, but I enjoyed the process.
About 5 years ago, I got very sick. During my recovery, I discovered you and your colleagues on UA-cam. Since then, I have been a junky watching mostly woodworking videos. I must THANK YOU and your colleagues for teaching me so very much. I moved to a new home and created a shop on casters (I have to move cars) and have tried many of the things YOU have taught me-and bought way too many new tools!.
I now spend as much time as possible in my shop and have actually created some pretty good project products and shop furniture. Without you to help me through my convalescence and your clearly understandable videos, I don’t think I would be enjoying this hobby as I do. Thank you and the whole UA-cam woodworking community.
Another method of making fittings is to heat PVC pipe fittings that are slightly undersized. After it's soft enough when heated, force fit them to the fitting that needs to be fitted to, allow to cool and now new fitting is form fitted. An added benefit with PVC is the self lubricating characteristic that allows fittings to be easily readjusted or removed with less binding.
Just make sure that you do that outside with the wind blowing away from you. Heating PVC causes it to emit toxic fumes. You could also use heat shrink tubing.
Great collection of tips. I have one to add about the bucket top cyclone. I also use mine for general cleanup and found that putting a couple of bricks inside the 5gallon bucket stops it falling over all the time.
Such a good video for me at just the right time. I'm in the process of re-doing my tiny (9' X 17') garage workshop. I'm pretty much starting from the ground up so all these types of little tips and tricks are a God send.
I told my wife that I needed to buy a 3D Printer. Oh, we laughed and laughed.
😂😂😂 persistence is key!
@@smashyrashy My wife is. 😂
Hard to justify a 3d printer, until you have one. Now, im glad I can CAD and make my own brackets, fittings, etc. It's at least paid for itself.
ive got 5 of them and am now starting my woodworking/shop tools collection. you still have a chance to make it out the other side w/o a printer
My wife says I have switched to shopping mode so she is expecting me to get one pretty soon. Our problem is with the high humidity we have since we are only .6 miles from the ocean.
Loved the video. I've been working on my own dust collection system and this video gave me some new ideas. Thanks!
The fitting should always go from smaller to larger, when possible. This helps eliminate the lip that can collect dust and debris that can clog up the hose.
I've seen people use PVC DWV to make custom fitting by heating them to the point where they can be stretched, bent, and manipulated to fit other sizes and needs.
yep, it'd be more efficient going outside vs inside, but the inside of both were smooth vs the outside being ridged which wouldn't be good for a plastic coupler
I have done most of your great suggestions but instead of the "secret weapon " I rigged up a deadman pedal which powers up both at the same time and costs a bit less. Keep on making those very helpful videos
I ordered and received the dustopper today, auto vac switch comes tomorrow. I'll be setting this up for my miter saw this weekend. Thanks for the ideas, can't wait to get rid of the useless bag on the saw, too.
Brad, the pace of this video compared to the last one is much appreciated! Even though this video was supported by Home Depot, that does not lessen the usefulness of the material you cover here. Thanks!
I’m so glad that I’m not the only one who was having a hard time finding the right fittings. I had made a comment to a HD employee and he gave me a hard time about it and said “it’s because you don’t know any better, you’re probably not looking for the right size” after I’ve shopped online and in stores knowing ALL the diameters needed for my power tools in my workshop. I made my peace with the fittings I was able to find and it helps but I still feel inefficient. Thank you for posting this video! Also, I’m loving the box from tip 9. Keep sharing content, you are awesome
Great video! I got a Dewalt 10 gallon shop vac for this very reason. Great ideas for upgrading my system. One thing I wanted to mention about the 3D printing is another possible option if you don't have a printer of your own. Try your local library. Our library has a few that you can use to print things.
Nice one, thanks as always. I'm with Joe Blow Below- I don't have a 3D printer, I haven't had the patience to teach myself any CAD/CAM software, so I just kind of heat stuff up and cram it together as best I can. PVC and ABS are cheap! Use good ventilation., and stuff something more or less heatproof inside of the tube so it doesn't collapse when you bend it.
I've found #1 plastic - PETE - to be really helpful, as it shrinks when heated. Many, many types of bottles and jars from the supermarket, including many sizes of soda bottles, are made from this plastic. Cut the ends off, slip it around the two pieces you're trying to mate, and put the heat on it. It will shrink to fit both so you get a removable airtight seal.
Finally, those boxes with a bunch of furnace air filters and a box fan blowing out the end are great for protecting your lungs.
I have been using pool skimmer filter socks on my shop vac filters. When they get dirty just grab the sock, stretch it out a little then let it go. This saves the filter and are easily replaced. I got 30 in a pack for like 12 to 15 dollars.
Great tip! Been doing this one for years. Cheap fast simple. I use the bag filter for drywall dust, but pool socks are great for wood chips and dust.
The dustopper leaks around the mating surface between it and the bucket. A thin line of foam tape drastically improves suction
I came to make this same comment. Huge difference!
great tip! Gonna do that now
I used a bicycle inner tube and laid it over the bucket lip to help the seal.
I haven't noticed that with mine. I will have to check it when I have it out next.
Thanks for the tip. I will check mine tomorrow!
Great video! I bought the iVac automated vacuum switch because of your video! It works awesome! I used to forget to turn on the vaccum when making cuts! It turns on and off automatically. I mounted the box to a piece of plywood and put a French cleat on the back and now it's hanging on my wall and I can plug tools in as I use them with my ridgid shop vac!
Your opening 20 seconds were absolutely fantastic. As you are manipulating that bag I was saying to myself "those things don't work no matter what he does"
And then I got to the punch line which made me smile so thank you
Yes! I have been waiting on a video about your dust collection systems. I'm going to implement some of your tips. Would love to see the rest of your dust collection tips for your other machines and power tools. Always motivated by your clean shop. Thank you.
yes, hoping to get a good response on this one and if so we will cover other areas too.
Brad, I put everything together today with the dustopper and vac switch on my mitre saw. I'm so glad I saw your video! I love this auto vac switch, and I can see a difference already just in less dust in the air while using my miter saw. Next thing I'll do is build a box around the mitre saw to try and capture the rest of the dust that comes out from behind the blade. Cheers!
Seems like you need to make two vacuum intake ports, one at fence face (level @cut plane) and one at back of blade (@level of carried cut litter) you’ll catch more of the big stuff tossed along side the cut wood.
All great tips! I have a similar hood, and i've placed a rectangular conical port hooked into my DC50 to catch and pull dust that gets past the hose in the back that goes to my small shop vac.
I’m going to tackle a miter saw dust collection “thing” soon as well. Let’s see who can over-engineer it more 🤓
Hey, I'm moving in on your turf. You see that 3D print!?!
I can't wait to see this showdown ............. I can already hear the eerie Spaghetti Western music playing in the background!!
Enjoyed your video very much. I just got my secret weapon today. It’s a remote controlled switch that I keep on a belt loop so whichever side of my 4x8 rolling workbench I’m working on, I can quickly turn on or off my shop vac. I’ve got my miter saw, table saw, jig saw, belt sander and palm sander that I connect to my shopvac. The remote works perfectly. If I used your secret weapon I’d need 5 of them and I’m too cheap for that. I made a dust collector for my miter saw that looks like a scuba set up with dual hoses plumbed to the shopvac. It’s stationary and works for bevel angles but needs to be removed for miters. Not perfect but solved the 12” Dewalt habit of sending sawdust everywhere.
I love looking at all the great ideas on UA-cam.
Thanks for putting in the work to bring us informative entertainment.
Cheers.
Great video Brad…I’m building your 3 drawer cabinets and making three of them to do the mitre station setup…so this video was perfect timing, thank you. I have one of those switches for my CNC and I’ll get another one for my mitre saw. Jud
Awesome video. The best design I’ve seen for enclosing a dust hood is cutting strips of plastic sheeting to let them hang vertically so the saw can still be rotated.
I came for the puns and got so much more
Thank you as im actually redoing my workshop this weekend and a miter stand is what I'm building. Now I will include storage space for the large shop vac and bucket duster
I'm building a cordless dust collector right now, it's a fun project! We got to remove that dust in the shop!
that sounds fun!
@@Fixthisbuildthat what is a dust collection system
I've seen several custom solutions. One I like best so far used clear vinyl around the sides and face. When I set up my dust collection I'd going to give it a try.
ahh yes, kinda like walking into a cooler
Great video as always. I had the same problems with my fittings and ended up sanding down the diameter and there is a 'little' duct tape holding things in place. The vacuum switch is one of my favorite 'tools'.
Since you asked, I would not hook up 4" dust collection. I made mine with it open under the MS and all saw dust that doesn't go up the shop vac just floats into the drawer under the saw. I can sweep the saw off and all dust falls into the drawer. Once a month (or more) I empty the drawer. If you are worried about the fine dust, just put a fan with air filtration nearby and run it with the shop vac plug in. I did a several videos on dust collection and such on my MS station. a couple of years ago. If interested, they might give you some additional ideas to look at. Great channel, thanks. I don't always comment, but I do always watch.
I went to my local wood caft store and bought two angle connectors to fi my rigid 2 1'2 hose. Had an old garbage can....full size....cut hole in top for each of the connectors which were fastened with pop- rivets. Now one hose goes from the saw, router bench, planer, etc. to the garbage can...than a second hose goes to the Rigid shop vac. This works great for all but especially the planer which really puts out tons of wood chips. Most end up in the modified garbage can and very little other than dust goes to the shop vac. This is the same princil used in all those other dust collection devices....but mine was dirt cheap.
Now to my gripe....like you I have Rigid shop vacs....three of them currently. One is about 25 years old and works like a champ still....the next one is about 12 years old....last is the latest propack rectangular unit. Each of them has their own fittings for the hose and accessories. I go to HD and try to find adaptors between them and while they have lots...they are each dedicated to a given size....2 1/2", 1 7/8", and smaller. I aso have the same orange hose you discussed and that does allow some cross connections BUT i had to use an old dual sided 2 1/2" male to male adaptor that does work great for connection and than stepping down....but I have not been able to find that same fitting again....and I would love to get a couple more. May resort to 3D printing but I am surprised that Rigid or HD doesn't offer more adaptors Maybe it is planned obsolescence ;-) I finally resorted to modifying some adaptors I had by using my band saw to cut them up and turning them down on my metal lathe....but that is not the way it should be.
Glad I found your video. Now I have a better idea of what I need to do to improve my dust collection for several stations, including miter. Thank you Sir
Always enjoy the content. Recently my daughter asked how do you builds drawers? So we watched your DIY drawer video and she loved it and wants to make drawers now.
I learn more about vacuums than I did about miter saw tips.
I have similar set up, big rigid vac, put a y with 1 hose to miter saw and another stepped up to 4" with a rockler 10"×4" dust trap on table behind saw with hood. It gets about 90+% of the dust. Works great. I have this incorporated into a movable miter stand similar to yours.
hmmm, never thought of actually splitting the suction of the vac...I'll have to consider that!
Any chance of a pic somewhere?
I just bought your lumber cart plans and built it yesterday love it man! Love the content as well, keep doing what you do!
Awesome! Hope you enjoy it!
The black table you had your saw on at the start is a great work table. Have one just like that (well it was when it was new) and use it all the time. Must be 25 years old by now. Oh yea and the video was very good. Keep up the good work.
I had a home made box/shroud previously with a hole in the bottom attached to my 1 hp dust collection system. It did not work. I have seen others add plastic curtains to increase the suction. I did not try this, so I'm not sure it would work. I have since bought and use the Rolland shroud. Even if there is plenty of suction, I need to shake the shroud from time to time to make it drop in the collection port. What it does really well is to contain the dust within the shroud. It has made a world of difference in my shop.
I ordered & built your mobile miter station & it turned out perfect. Thank you for all you do. Great videos & you're not too hard on the psyche to watch/ listen to. Keep on, keeping on. Good job!
thanks so much for sharing that! Enjoy the build!
Wanted to do the same, then i saw imperial! Please make your plans also in metric so the other 190 countries could use it as well. Thanks!
The only suggestion I would make is to add a skirt around the opening of the hood. Use magnets to hold in place until you need to make a beveled cut. this will greatly increase what you catch. Love your builds! Thank you for sharing your time and talent!
You have a nice solution as-is. In my case I plumbed in central vac combined with an iVac switch but I regret my solution. I often walk up to the saw just to make a quick cut, and by the time my collector is up to speed I've already finished my cut and moved on. The Shop- Vac fires up almost immediately, so you don't have the lag issue that I have. What does work well for me is enclosing the front of the dust hood and my downdraft area behind the saw...with nothing connected directly to the saw. Works well.
At first I thought having to plug that pigtail back into the unit was stupid, but I looked it up and it's for when each tool has to be powered on a different 15 amp circuit so you don't blow a fuse. Nice feature!
Brad: these bags have huge holes in them. Kind of like the Bengals offensive line. "
Me: AWW!!! 😮
Great job. Thank you. At the moment using our spare bedroom as a wood working shop....table saw, mitre saw...ah yea wife not to happy. Perfect timing with your video. Tomorrow 14 gal ridgid shop vac.....fine filter....dust bags, hopefully separater etc. its a start. Thank you again. Love the swithchy thing also👍👍
I attached a multi plug in to the vac switch and attached bandsaw, table saw, router table, miter saw, and drill press to the multi plug. I made a plenum and attached each machine to separate blast gates attached to the plenum. The plenum I attached to my dust collector which was attached to my large shop vac. The shop vac chord I attached to Opening the blast gate to the vac switch and turned on the vac. So I cuold open the blast gate to the tool I would be using and draw the sawdust into the plenum and then into the dust collector.
I modified the vac bag so that I could dump what little dust was in it and then reclose the bag. Over the pleated filter I placed a section of sleeve from a polyvinyl jacket which stopped most of the real fine dust making it through the shop vac bag to the pleated filter.
I added an additional blast gate for a hose for floor vaccuming.
I built a off feed / workbench / tool housing bench which I housed the miter saw, band saw, and drill press. Each of these tools I attached to a folding shelf which rotated the tool up through the top of my bench through a horizontal door equiped with 180 degree hinges. The tool shelves had a wing attached by door hinges (not cabinet hinges) which supported the weight of the tool like the miter saw off feed supports in the video.
The workbench acted as off feed support for the router table and jobsite table saw.
Since my shop is a portable 10x20 building supported off the ground I was able to run the vac to plenum hose under the shop between the floor joists. This eliminated my tripping over the hose everytime I rounded the workbench.
I built “your” mitre saw station…works great. Dusty though. Loved the intro to this video and how to properly position “the bag”
I have a couple of the nylon (?) miter saw dust hoods that he alludes to that work well for me. The first one I bought is a Rousseau and the second one is a Vevor, which is just as good as the Rousseau and was considerably less expensive. (Both from Amazon.) I don't hook up any vac to the miter saws themselves, because it's too awkward with the dust hoods in place, and because the miter saws throw off a lot of dust from all different directions anyway, which the hoods capture - which is what they were designed to do, and they do it well. They practically envelop/cradle the saws, leaving just enough working room. Pretty ingenious (but simple) designs, the way these things work.
Plus, static inside the hoods tend to pull dust in and then the dust clings to the inside walls of the hood. Occasionally I'll just give the hoods a shake, where dust settles down to the 4" exit port at the bottom near the floor, and is collected into a cardboard box sitting on the floor. Anything remaining I clean up with a handheld vac. I guess I'll probably in the future experiment with hooking up a shop vac to the 4" port, but for now I'm too lazy to do so and to finagle the room to do it.
But the con is the initial assembly and setup, which is a nightmare. Better have two (or three) persons handy to assist as you cuss your way through that. VERY awkward. (The Vevor is essentially identical to the Rousseau in that respect.)
As far as shop vacs are concerned, I suspect every manufacturer will eventually get on board the trail blazed by DeWalt, and make their vacs "quiet" - or MUCH quieter compared to the ear-splitting noise produced by regular vacs. These quiet vacs are a game changer, and don't even require ear protection by those folks concerned about their hearing, or at the very least are annoyed by the noise of regular vacs. I have one of those among my collection, and am amazed by how quiet it is.
I also have the upgraded version of the Dustopper ("Dustopper Pro") sold by Home Depot. THIS is THE ONE to get. Fits very well onto a cheap 5 gal. bucket with its secure clips. None of that expensive collection bucket nonsense or cobbling up a collection bucket. Get a semi-opaque HDX bucket from Home Depot (so you can monitor how full its getting) as well and you'll be good to go.
And not to slight Ridgid, they are my go-to as far as (quality) plumbing repair tools are concerned. I live in an old (cast iron/lead pipe) house, and have an ongoing project to replace all that stuff with pvc/pex pipe. You haven't lived until you've dealt with all that in a narrow crawl space.
I kind of went the opposite approach and ONLY have a 4" dust chute on the bottom of my miter saw hood hooked to the Dust Collector. The whole thing is hobbled together but the fine dust that comes out of the back of the saw just hits the back of the hood and falls down into the 4" DC port/chute. However, this does require the miter saw to be very close to the large dust collector.
Actually, picked up a cheap wall mount Powertec DC to dedicate to the miter saw. Since I had the 4" fittings this cost less than buying a heavy duty shop vac, hoses, auto-on/off, etc. I'd say if you have the space for a shop vac and DC combo, that setup is best. However, I'm happy with a 4" DC hood connection vs. shop vac direct connection if you only had one. Great video as usual.
I'd love to dedicate a larger collector to the saw and have it on some type of automatic switch. That'd be great
Not following too well. What does the powertec dc do better than shop vac?
@@carenclemmons5002 Physics. Single- or Two-Stage Dust Collectors (commonly using 4" or 6" duct work) have the advantage of sucking a higher volume of air than a shop vac. A dust hood surrounding a miter saw contains a significant amount of cubic space filled with dust, so using a dust collector that can move a greater air volume has an advantage over a shop vac.
Good timing! I just got a dust cyclone and reminded me I need to order more filters. Thanks for the useful info!
you're welcome!
I added a small tent behind my miter saw to catch all the dust and chips. Works well. Look for "mini sun shade for beach".
I use a dust hood similar to yours with a front to keep the dust from flying at me. Works great. I don’t even use it with a shop vac
Is the front removable for mitered cuts or just wide enough to let the saw move the full range?
@@Fixthisbuildthat wide enough to swing both ways
Besides the stock dust port and shroud, some woodworkers have found that it pays to collect dust at or behind the miter saw fence. Some indicate that the best solution is to use a combination of stock dust port AND shroud, or stock dust port AND at-the-fence dust collection, etc. I’ve been wondering how well such combo systems work, and specifically, any trade offs that arise. Your thoughts or findings are always appreciated. Thanks.
This is great Brad, thanks. My old shop vac is starting to go so I need a new one. Looks like you like the Rigid brand. I’ve looked at so many cyclone systems on line but am not able to see them in action. I’m in a dilemma on what to buy. Any tips you have would be awesome. Thanks for all your videos.
My fav UA-camr!
thanks!
Fantastic info, Brad! Thanks a bunch! 😃
Stay safe there with your family! 🖖😊
thanks, MC! Stay safe
I use the Rigid 12 gallon vac with the dust separator. However, if you are using a shop vac, please vent the exhaust side to the outside of your shop. There will still be small dust particles that the filter didn't catch. Also, it allows you to use the cheaper filter because it vents outside. Mine is in a permanent location with a hose long enough to reach all my equipment. (small shop) I also have a 2x2 box fan with a furnace filter in front of it and a 2x3 window fan mounted in a wall for those days where more is needed (cutting mdf or using something that doesn't have dust collection capability) My air quality monitor rarely shows higher than 10. (measures half microns). Thanks, Brad, for talking about this important subject.
I can't vent it outside due to where it is on the wall, so the Hepa filter is the best alternative for my setup. And I don't think my neighbors would like me spewing dust at them :)
@@Fixthisbuildthat I understand. My comment was more for those that could.
Oh man the rubber connector with the clamps on it is exactly what I use to adapt the fitting on my table saw. It does an okay job but I think 3D printing an adaptor is definitely the way to go. I've always wondered, when using a hood with a miter saw, would you still get a decent amount of dust coming out towards you? It would be interesting to try to use a fan system that would blow towards the saw from above and or behind you and shove any dust that might try to escape the hood back towards the dust collection port. Great video - thanks for sharing your tips!
yep, exactly what I'm wondering. If I start getting a face full of dust I'll have to rethink the setup and add a front or more suction
I found the best dust collection for my miter saw was just to stop using it (12" Bosch glider). I now cut my rough lumber down with a jigsaw and once it's milled, I use my crosscut sled to cut accurately to length. Clean up is much easier now and less fine dust in the air.
Excellent solution if the only tool you have is a miter saw. I had to come up with a different solution for my 10 x 20 shop and my 6 tools that spit out loads of sawdust. I needed centralized tools, a centralized vac system, and an out feed for my table saw. Having all my tools around my outside walls was not a solition unless I had a larger shop, a deeper pocket, a vac per tool. My outfeed table houses 4 tools, miter saw, drill press, band saw, and surface planer. Each tool has it's own foldable 180 degree lid. The sutface planer, miter saw, table saw, and router table utilize the bench for pot feed, their work surfaces are all on the same plane. I made a plenum that fits inside the bench and is also accessed by another 180 degree lid. The plenum has 6 diy dust gates, 4 for the tools housed inside the bench and one for my table saw and one for my router table. To operate my vac I also use the automatic vac switch and a dust demon cyclonic separator. My 12 gal rigid vac has a bag filter that is modified to be easily emptied, a porous slip on dust sleeve, and the pleated filter. All 4 tools inside the bench are attached to a 3/4" plywood shelf that is hinged to the bench framework with standard door hinges. Works for me and I can rip 4 x 8's lengthwise inside my shop on the table saw.
All my machines are on rolling cabinets. I made wooden adapters for each machine, then one for the hose that is universal fit. Works quite well in a really small shop.
Sounds great!
One thing, might improve things a tiny bit: where you use the 3D-printed angle, instead of going straight up, can you come to the side and/or down? Not that the dust has a LOT of choice, but a 60° turn followed by a 180° bend in the flex hose slows the air down a lot more than _not_ having that 180° turn. But then, if it doesn’t fit, it doesn’t fit.
it's more about having room for the hose to move when going to left and right miter angles
It's amazing how home depot hasn't caught onto ever shop vac complaint about accessory attachment diameter and hoses. Even their accessory pack that supposedly fixes this problem fits nothing. I did the same thing as Brad. But I posted to a local Dad's FB group in my town and asked if anyone could 3d print me a coupling to go from my shop vac hose to the port on my belt sander. One of the Dads did it for me that day.
Use gravity! At my first shop, I had a dust hood installed under the platform where my miter saw sat. As all the dust flew to the back and bounced off the back wall, it fell with gravity and the dust collector sucked it into the chute. Couple that with a semi enclosed hood and you’ll be all set!
Here I am trying to watch woodworking videos to fill a Super Bowl sized void in my soul and you had to start it off with a Bengals OL reference. Thanks for that! Now to drown my sorrows in a Skyline 3-way.
I'd for sure add a coney to that order and an extra bowl of crackers!
Something you didn't mention about that auto dust collector box is the two power cords. If your saw and dust collector trip your breaker (or if you are using it with a planer and larger dust collector) the box has two power input cords so you can plug them into two outlets that are on separate breakers. Many don't have that option, but the one you have does.
lol the clip where you're leaning over the saw and its by your neck as you explain the back connection made me laugh, excellent video, whomever is doing the editing is getting better.
I have a furnace fan in the cabinet under my chop saw with a large hole in the back of the hood, on top of a baffle holding 3 furnace filters to keep the dust from being pulled through the fan. The blower exits along the floor at my feet. This keeps the air moving in the shop & the overhead air cleaner gets the airborne dust that gets away, which isn't much. It works really well and it's easy to clean out. The best part is it's quiet! I'll leave it run for about an hour at the end of the day while I clean up.
I have a storage room off my carport where I can store my tools. When I want to work in my shop, I have to pull everything out and my carport becomes my shop. As you can tell, it is rudimentary at best right now. Our goal is to build a garage and close in the carport, then build the carport into a functioning shop where I can work and play till my hearts content. Will be needing to clean and organize what I have and build many portable items for my tool.
There is a 90 fitting that fits that miter saw. It's a 90 street elbow designed for a vacuflo system. The 2.5 inch rigid hose fits the other end well
Your desk to it seems like a great idea and I am going to build one within the next week. Thanks.
My saw sits on tool of a tool cart. Two other carts flank the saw's cart, and they are connected together with a plywood plate over the 3 carts. The saw's cart sticks out farther than the other carts so there is a space behind it. I built a small box to fit under the center cart table and I have a 4" pipe going through the table. I drilled holes in the plywood above the catch tray for an area larger than the area of the 4" dust system pipe. A blast gate is in the suction line. I have a hood around the saw and use plastic sheet strips (weighted on bottom) to enclose the front. The sawdust shoots out of the saw and the dust collector pulls the dust away. I have modified my system numerous times over the years. This version works well. My dust collector has a big cyclone before the DC unit.
3d printing couplers is a big win, been designing and printing couplers for the new dust collection system at my local makerspace including the big 4 and 6 inch pipes, $50 worth of plastic can easily make all the turns etc as opposed to buying them all given that one can easily cost $50 right now
that's awesome! Are you listing them on thingiverse?
@@Fixthisbuildthat Some of them I have, once we print them out and verify they are working I am uploading them, so the larger stuff isn't there yet
Good morning, great way to start my day. Ty
you're welcome!
Great video. I highly recommend the funnel style cyclone dust separators as their shape allows even smaller particles to be removed from the air compared to the flat top one shown in this video. At my previous job, we used 2.5 storey sized to separate product in the plan appropriately to meet spec. The smaller particles are lighter and to avoid being pulled into the vacuum need to be further away from the outlet, hence the funnel shape.
All of our local libraries have 3D printers you can queue jobs on to. It's a bit slow (takes about a week to get a job done) but it's lots cheaper than buying a 3D printer 😅 ($2-5/piece printed so far with the small things I've had them make for me)
When I make vac hose adaptors, I try to use the Outer diameter of the tool instead of the Inner diameter. This the adaptor that I 3D print wraps around the tool’s port, instead of inserting inside. Inserting a hose adaptor leaves a 1/16” edge ring that blocks the dust. Always plumb your air for absolutely minimal resistance to flow.
didn't think of hooding my vac to my mite saw great idel thank you
I have a Home Depot Dustopper and it works really well. Highly recommended.
Same here and I agree, especially for the price, it does an amazing job. My vac and dustopper are loose right now which is why I stopped by. Need a cart or something since my shop also has to hold cars 🤦♂️ so everything is mobile. Thought about getting the portable 4.5 HP with 1 1/4 hose but you talked me out of it!
@@poseyk01 There are a number of dust collecting carts out there. One is from April Wilkerson. I built mine using a furniture cart I purchased from Harbor Freight and simply mounted a piece of plywood on top of it to fit both a large shop vac and the Homer bucket with the Dustopper along with cast iron poles on each corner to give me something to grab to pull it around my shop. But I do like the vertical carts like AW's. I just don't want to spend that kind of money for plywood at the moment. But, also look at Brad's plans to see if he has one as well.
Thanks 🙏 nice presentation
thanks!
Best outlet I have ever used is called the iOutlet. The minute you start the tool, the vacuum will come on, and stay on for 10 seconds to clean the hose.
There has yet to be a miter saw setup than can catch all of the shavings. The best I found was through Rockler, which was made for a radial arm saw funnel. You still will get dust everywhere, just not so much of it. Those require a 4" hose system to collect the dust which you can get from Harbor Freight for around $250 (USD)
A little realization on air flow: exhaust manual recommends air flows for circular (radial, table, etc) saws in the range 350~500 cfm (cubic feet / min). And the biggest problem with a miter saw is the uncontainment of the particulates. No matter how much suction ... well, within reason ... you put on that little duct connection, a lot of material escapes around the sides, and top, and bottom. Circular saws, operating at very high tip speeds, generate a lot of particle velocity. A shroud application is about the best you can hope for. You made a wooden shroud (I used clear plastic). I put a 16x20 scoop in the bench surface behind the MS, and a 4" duct to my DC evacuates the shroud area. It's about 85% effective, but on small particles it should be about 99% (because small guys just go with the flow).
good tip!
Does the clear plastic just work as a directional funnel connected via 4” adapter as well as pull suction at the plane of the cut, ?
@@carenclemmons5002 The shroud is 2" higher than the MS, about 6" wider than the MS, and curved on the back (particles bounce down), and the scoop is the 16"x20" behind the MS. I framed the shroud from curved plywood and then used dowels for horizontal connectors to the sides, with the curved surface and the two sides made from clear plastic cloth. Footprint of the shroud is about 24" deep and 20" wide. Allows light on the surface. Sides are even with the MS fence so no interference with workpieces.
FILTERS: Keep in mind, when it comes to shop vacs, and dust collection the “better” the filter, the more suction you lose. While it’s not always a HUGE difference (or loss), it’s something to be aware of…performance vs “health” (potential particles breathed in).
we have this exact same issue. We have both the shop vac and the big HF 4 inch dust collector. Our saw is a sliding miter so we don't have a ton of room behind the saw. I want to do a big cabinet for the 4 inch port. I am thinking a hood like you have made and then a big funnel under the saw that exposes the entire back of the saw so that it will basically suck everything that gets flung backwards
The best thing about the dust hood is that you can store things on top of it.
Another place to store junk, that's all I need 😂😂
What I would like to see is a more powerful vacuum that is still small. I have that same Dusthopper, and bought a small Ridgid shop vac, because I'm only getting 5g of dust storage and the idea is to stop before I fill that up (depends on the day). I didn't even think about the power issue, but that makes good sense and I thank you for pointing it out. Seems wasteful to pay for tons of shop vac volume that I won't use, though. Hmm. I must shop!
Love the bucket idea
Great info Sir. Thanks for posting.
Instead of a shop vac, I bought a used whole house vac from Facebook Marketplace and exhausted it outside. The control board was all that was bad so I wired it direst and used a automatic switch. All for less than the cost of a good shop vac. It works so well that I ran 2" pipe all the way around the shop to the table saw over blade guard with a auto switch to turn on the vac. Oh yeah, I used a little dust clyclone to keep the majority of the dust out of the whole house vac.
And I’m buying those miter saw cart plans next, working off a job site stand now that is a total pain
Interesting. I gave up on using the built in dust chute on my saw, instead I built a housing around the saw. It works... Ok. I'd like to figure out a combination of both. I have a 4" pipe to my dust collection coming out of the bottom, and it keeps most of the dust contained. I do still get a bit of residual buildup on the bottom, which I just push into the 4" hole from time to time.
I have a dust hood and a small shop vac under. But its awkward to use and I can't swing the miter saw fully. Need to do some work. But I think I just want to build a new miter station. Mine is currently too high. And then I can address the dust collection better. Also having the matching button would help sooo much. Then... I think I'm just going to do away with the miter station and so a small miter cart like yours. Who knows!!! LOL
hahaha, choices...choices!
I use 3d printed parts as hose adapter all the time. If you can model your own, try to make the transition smooth instead of a hard turn, even a hard 135 degree turn is not as good as a smooth turn. One method you can try is to model one end, model the other end at 90 degrees to the first one, then loft between them with tangent, then shell. No consumer FDM 3d printer can print exactly the dimension you modeled; flow rate, print speed all have some effect on it. Print one, measure and calculate the difference, compensate in CAD, print again. This worked out the best for me.
Although you could use the automatic switch as you detailed in the video, the second cord is meant to be used on a second circuit so that the entire load of the saw and the dust collector doesn't overload and trip the circuit breaker.
hmmm...that makes sense, but with the length of the cord they give you I would find that very hard to work in many applications.
@@FixthisbuildthatThat Perhaps an extension cord of proper gauge would solve the length problem?
I've made something like this before about 6years ago.
I added 2 flap doors on either side of the saw to close most of it off except for the blade area and handle. If I wanted to do a 45 cut I'll just fold one flap door over the top to allow the angle.
Great video. For those who don’t want to buy all that stuff separately, the Festool CT15 dust extractor is $400 and does everything this setup does but contained into one unit. Don’t get too excited though, they won’t give you a hat until you’ve spent at least $4,000, give or take…
hahaha, all about that free hat though :)
What I found most interesting about this video is the port on the front of the saw. I have a DeWalt and the dust port to suck up the dust is just a wee bit of a thing. Did you makes larger port for that saw or does it come with it? Now that would be something to figure out for the 3D printer
Thanks for info on the Ridgid vacs. I ordered my hepa filter already.
Your lungs will thank you
A heads up for those without a 3d printer and have a Microcenter nearby, if you sign up for text ads, you’ll get a coupon for a Creality Ender 3 Pro for $100. It’s a good start for 3d printing for an affordable price. I did this in August and would’ve just canceled the text subscription but haven’t received a single text from them this entire time.
that's a killer deal!
Appreciated all the useful tips. Did you eventually incorporate the dust bucket cyclone? And if so please show
Thank you.
A lot of public libraries have 3D printers available for use.
great tip, didn't know that
Thanks for sharing this. Just found out my library has one!
Awesome stuff Brad, thanks for the info! 😃👍🏻👊🏻
Thanks, Fred!
