Table Saw Dust Collector

As I’ve posted before, I tend to take equipment, and materials work the best they can for my needs. I have gone to a whole new level now with permanent, “fixed”(I hope), dust collection. I have a “screamer” table saw that I built a massive rolling workbench for, with miter slots, and storage. I struggled with dust collection on this machine the most. No matter how many holes I sealed in the case, or the shop vac hookups in different locations, it was still a ridiculous mess. So after seeing some ideas on here, and the web, I knew it was time.

So I built a basin collector. I used a 16” x 6” HVAC duct, with a 6” round opening at the bottom. The mouth takes up almost all of the surface that the saw sits on. But I’m totally ok with that lol. I then ran to a 6” adjustable elbow, and then into a tapered 4” reducer, and then to the hose. After a few sheet metal cuts, and some minor adjustments I can report this thing works like a champ!

I have my whole setup running through a “HF” 1hp wall/bag style impeller dust collector. I finally went with sched. 40 PVC for all of my runs, and you would think I had a 3hp cyclone. The table saw collector sounds like a low rpm jet engine while running, but man, does it pull some air. Even through my homemade zero clearance insert, it has pull.

I’m still in the process of finalizing placement of other tools in the shop, and I still need to build that router table (which feels like I’ve been waiting on for months now lol). So I have some PVC runs capped off to add to over time, but I finally feel like I’m breathing some clean fresh air for a change in the shop. And I have a new WEN 3410 air filter on order, which will hopefully help even more. I can report back in that later if anyone has any interest.

If anyone has any questions about my connections, just let me know!

Great setup! I was a little worried about the 2nd and 4th pic….it looks like you might be losing a lot of static pressure with all of the bends, but then I stepped back and looked again. Your total run is a very small footprint, so I wouldn’t think it would matter.

I have the Wen air filter in my shop, as well. Love it! It does a great job in my small, basement shop.

I just hung the WEN last night, and haven’t been able to put it to good use as of yet. However, it does move quite a bit of air around. Did the “smoke” test off of my cigarette(I know it’s bad for me lol) and it was gone in a flash.

I was a little worried about the pressure loss as well. But, so far my longest run is about 7 feet going to the table saw. And it doesn’t seem to have any issues at all. Especially coming out of the very over sized “big gulp” ducting I did under the table. I plan to make another run along the ceiling where I capped it off just past the table saw drop. It will be about another 8 or so feet to the sanding station, and downdraft table I’m going to build. As it sits now, I can have 2 gates open with only minimal pressure loss. And I like to think that it helps that I sprung for the more expensive “smooth” 90 degree transitions off the main feed, instead of piecing together 2 45 degree sections. I test everything with the “hand full of sawdust” method. Each gate will pull a standing pile of sawdust in my hand from about 2 feet below it’s opening. As well as small cutoffs. So I’m pretty pleased so far. I’m sure I will lose some more pressure when I extend the ceiling run again, but in the future, the collector will get a major upgrade as well. And I will add a “true” cyclone in line. But for now, I can breathe a heck of a lot easier in there lol.

Thanks for the feedback!

This setup has just given me an idea for a new plan with my TS. I run the Jet Powershop with a dust port out the back of the cabinet. Despite having 6” piping and a 1200cfm system there just isn’t enough pull to completely evacuate the cabinet. By moving the port to the bottom where dust can fall into it should be a big improvement. Thanks.

I’m glad I could help! I will say one thing, I kept the front lip of the HVAC duct almost completely in line with the front of the table saw interior. I did this to have a smoother line right from the saw blade to funnel the dust right down into it. If I had a larger “non-screamer” saw, where the leading edge of the blade was further back, I would have positioned it more in line with that. I am still toying with the idea of adding a wye fitting at the gate for the table saw, and making some kind of over the blade collection as well. I have been working that design out in my head over the past couple of days. And if I do it, I will add some pictures too.

Interesting fit out, I am surprised you have so much clearance under the saw mine I am lucky to get a 3” flex duct out of the base.

Is it attached to your limited edition saw?

Opps Just saw Picture No 6!

I also saw a red object a in front the HF 1hp wall/bag style impeller dust collector Just what is that? an additional extractor?

I built the saw into a massive monster of a work table. Made sure to leave plenty of room underneath. The stand that came with it will probably be re-purposed for something else. And yes, it is a “limited edition”. The red piece to the left of the collection bin/bag is the actual impeller. That is the only “suction” piece. And the way it’s configured seems to pull a substantial amount of air so far. As I add more runs, it may drop off. But we shall see as time goes on.
