This video depicts modification to my original dust collection system for my DeWalt 745 Contractor Table Saw.
Main Idea or System: The overarching idea for my system is a top of the table saw over arm dust collector with a separate vacuum source. This is supplemented with a high vacuum suction connected to the dust collector port in the back of the table saw.
Source of Ideas: I created my system based upon looking at several others on TH-cam: namely Dan Pattison, Justin Depew and the Saw Stop table top dust collection system. I’ve now revised and extended my system with my own ideas and am happy to report that it works to collect in excess of 95% of all dust. I later discovered that DeWalt’s latest contractor saw (model #DWE7845) has implemented the “under the table” collection method that I use.
Dust Collection System (2 main elements)
1) Table Top Dust Collection (demonstrate how it is made)
a. 1 inch square aluminum arm with drop down and adjustable dust vacuum device attached to a hose attached to a shop vacuum
b. The arm pivots out of the way when necessary (using other jigs or ripping narrow pieces)
c. The collector is detachable for ease of use.
d. The collector has a drop down side piece of Plexiglas that captures dust when ripping slivers off
e. This sucks in the remainder of the dust which the Dust Port misses
2) Dust Port Collection (turn over the saw and look underneath)
a. 4 inch hose connected to Rockland Vacuum Bag system
b. Underside of table saw has plastic sheet pieces duct tapped to saw bottom (this system (with mounted flexible canvass like material) was implemented on DeWalt’s latest contractor saw (model #DWE7845)
3) Total Dust Reduction
a. My guesstimate is 95% (talk about)
Demonstration
1) This system works where the Saw Stop system misses collecting the dust for the narrow cut off pieces.

James- thank you for sharing! It’s one thing to have the knowledge but it takes a special person to share it. Creating videos is not easy. Appreciate the time and effort!
Moony Thanks for your kind words! This comment helps me keep doing these videos. I (like you) believe sharing and having shop talk with others is one of the most important things we can do!

I really like your improvements to Dan's original design. The swivel addition as well as the flush table adjument is really clever.
Hey Laidback58, thanks for the comment. We all learn from others and it's certainly true for me. I haven't yet solved the problem of a close fence, but I have some thoughts

the tape underneath the saw is a great eye opener! just got the same saw and am trying to work out the dust issue - thanks for the tips.
Hi Joyous246, Thanks for the comment. Yes, the tape was the only thing i could come up with. The stickyer, the better. Also, check it once in a while (depending on how much you use the saw), and replace the tape that has detached. Enjoy! Please post any pictures or additional questions. Happy to collaborate. Jim

Very interesting and very well made. The issue I’ve always had with the type of overhead dust collector is when I’m trying to cross cut long pieces. The vertical frame element always got in the way. My solution is a similar type of boom but fixed to the ceiling directly above the blade. I also made mine out of ply and plexiglass but I wanted a narrow cover (to allow me to still use when cutting thin strips) but also a 4” hose. So, my cover is made of 2 pieces of 18mm ply with 6mm plexiglass either side. The dust hose goes in from one side through a hole cut in the plexiglass. The whole vertical boom is adjustable in height (two pieces sliding within each other) and can be easily taken out altogether.
So different - not better, nor worse - just made to my requirements.
An essential element to efficient dust collection below the blade is the control of the movement of air. As you showed, all holes, gaps around the saw (in my case, the cabinet) should be covered in. Then you need to make sure that you have enough of a path through the blade insert to draw in enough air to take with it the dust. Standard inserts have wide slits to allow for tilting the blade whilst zero clearance inserts do allow for thin rip cutting. However, a zero clearance insert probably will limit the amount of air being allowed in to an extent to impede efficient air flow; therefore, it might be necessary to drill some “air” holes in the insert but not near enough the slit as to negate the benefit of zero clearance.
That really is the result of all my trial and errors. I’ve been doing it for over 45 years and so I could fill pages and pages with everything that hasn’t worked out.
Thanks so much for your detailed and interesting reply. We have a lot in common and I appreciate your taking the time to share your experiences.
I was dealing with the same problem as you. I solved the dust collection problem under my table saw, by boxing it in and adding a 4" dust port but still when ripping a board up top the saw would cover you head to toe with dust. This overarm collector is an interesting idea and has me thinking. Thanks for sharing your idea. I usually watch many TH-cam videos to get ideas, then I'll design something for my shop. I'm sure a lot of us hobby woodworkers do this. Cheers

Put some weather strip on the plexiglass box edges or use those fiber strips like they use on CNC machines. Looks like broom Brussels. I actually have a cheap broom just waiting to be clamped and cut with the hot knife outside for this reason. Nice job. A lot of people will benefit from this. Love the dowel in the square aluminum tubing trick. Very clean!
Thanks Douglas Haber. Good idea - I will try that around the area that doesn't have good contact with the cut board or the table saw surface. Appreciate the comment.

Thanks James.
Tell me what shop vac you're using. Is it powerful enough? Do you get dust collecting below too?
@@philackerly3174 Hi Phil and thanks for the comment/question. My shop vac is a "Shop Vac Pro with 6 gallon, 3 peak HP, 8.4 amp device." Dust collection from the underside port on my DeWalt 745 is provided by a Rockler Dust Right Wall Mounted (650 CFM) and an attached vacuum bag

@@jamesrvs James when i go to the plan section i see some nice enlarged photos. My question is it looks like your using 4 layers of plywood so looks wider than your plans. Was this a first version of picture? Just curious. Also is your saw a 10 inch saw ? I have access to a lot of 2-1/2 by 1-1/2 to 1-3/4 wood. I am ripping these boards to about 2 x 1- 1/4 then gluing both together. Have access to lots of this wood . I am trying to decide of this plan should be thinner or as wider. Welcome to any advice in this manner
@@richardhinderer2057 Yes, I used 4 pieces of 1/2" plywood so that the 1 1/4" hole for the dust collector hose would have sufficient support (first version was not as thick). Yes 10" table saw blade
Send me pics when you finish! Enjoy!
@@jamesrvs Thanks i will
@@jamesrvs Good morning or should i say good evening James. I dont sleep well and went down to my basement workshop looking at the collector head i made so far. I am ot happy with it and not happy with using old plywood. So back to the drawing boards and starting over. Be patient with me as i truly want you to see what i have made when it is done. I can salvage the plastic and screws but throwing the rest away. Starting with laminated 3/4 inch lumber i am glowing us. I am a perfectionist so sometimes i just don't see my flaws until a project is started. So i promise i will send the finish project in pictures. Maybe a week or so until i have got it done or so i can show pictures. Thank you again you have peaked my thinking cap again.

well done sir

thanks for this, gives me a starting point for my own saw. i also watched justins video, if i can suggest putting a couple of threaded knobs in, one where the arm swivels on the tube to swing out the way, and one where the guard goes into the square box to hold the hood in place, it looks like an inch may not be enough to prevent the hood coming out if you accidentaly knock the hood when cutting, a threaded knob would lock both these into place preventing accidents, regards.

Thank you, James for sharing this great design! I’ve been woodworking for many years as a hobby + lots of finish carpentry for the home. I use a contractor table saw and dust collection just isn’t good enough. May try out your design. Do you have any dimensioned drawings you could share? How is the boom fixed at its base? Thanks again - we only get one set of lungs, might as well take care of them!

Very good I have the same saw, also had did you make the your table wider ..
Hi Mr. Trader. Thanks for the comment. Basically, I used 1/2 baltic birch plywood and tied it to a hardwood frame that was bolted to the table saw top on both ends. Then I added adjustable diagonal supports tied to the top and resting on the round horizontal tubes on the bottom on the saw. I also made round for the miter guage slot. I could put together a video on this if there is interest?
I guess this doesn't prevent kickback, have you ever had a kickback and did it damage it, thanks for sharing such a great idea
Hi Wayne Watson, no it doesn't prevent kickback and I have experienced kickback, but not because of this dust collector. The riving knife stays in place and that helps to prevent kickback. I always try to stay to the left side of the table saw just in case. Thanks for your comment!

I need something like this, no riving knife on mine to mount to
Hi Joshua Bromen It doesn't mount to a riving knife - it's held up by the horizontal bar mounted on the right side of the tablesaw. However, I'm concerned that you don't have a riving knife - have you ever had kickback as a result of not having one? Does your table saw not support a riving knife that you can buy? If not, I can send you a very clever method of building in a riving knife (out of wood) into your saw insert. Let me know if you want this information?

My concern with all of these is the blind spot created by the wood in the middle structure, perhaps some sort of solid plexiglass or acrylic material would be safer>???just a thought
Paolo Accomando, Thanks for you comment. I understand your concern and have given this some thought. My dust collector is easily removable, and hence I know where the blade is relative to the collector, and, I can easily see it. My collector is made of plexiglass and one can easily see the blade. Once I started using it, my concerns disappeared. Check out the plans I've made: www.downeastwoodart.com/available-project-plans/dusty-table-saw-dust-collector
Made this for my old Delta Unisaw. Only problem arises when I need to cut a piece really narrow. For example, less than 2" wide. At this point I don't have much room to get the push stick through as it is blocked by the dust collector. Thinking I can possibly make an extra long push stick?
Charles Nance. Thanks for your insight. I also have problems with narrow pieces, but the drop down helps eliminate dust. A narrow push stick will help. Also having a flexible (tape entry to allow narrow pieces in) will help.

Are you running the saw and the shop-vac for the overarm dust extraction on the same circuit?
Hi Tim Romano. Yes, I am and it's a 110 volts 15 amp breaker. I've had breaker trips when I had other power tools running, but have been able to run the Rockler dust collection motor, the shop-vac for the overarm, and the saw simultaneously with no problem. If the wood has built in stresses, I use wedges to reduce clamping on the saw blade and this works fine. Thanks for your question!

Instead of Plexi better use Makrolon, this is not splittering in case of emergency
@wthorwirth Good point - safety is key.
Hi James - thanks for the video. You should check this out - the Triton Workcentre, which developed an over the blade dust collection system more than 20 years ago. The Triton story is actually quite remarkable and the Australian George Lewin, the inventor, was a tech leader. The Workcente 2000 had the dust collector/blade guard, which used the table itself for support (via the riving knife), rather than an overhead support. Here is a video link from some vintage how-to guides. th-cam.com/video/9OTC6iIR3PU/w-d-xo.html Triton also made great advances in routers and router tables, again well ahead of their time. I commend any of these videos to you, since they will, no doubt, give you some inspiration.
