Tiny dust collector

[DynaGlide]

[member=70049]Joelm[/member] the space the wall mount units take up when you add the cyclone is substantial. I don't understand how anyone can say they save space when you add a canister the thing runs floor to ceiling on a 1.5HP unit.

Can you post a picture of the Supercell mounted in that same area for comparison?

I put this together for under $1,000 and aside from replacing the bearings in the HF blower motor it's worked out pretty well. Doesn't take up a huge amount of floor space either. Blower was upgraded with the 12 in Rikon impeller.

I wanted to move the dust collector next to the garage door. The Rockler wouldn't fit but the SuperCell is nice and compact.

I have a 4" run of hard pipe along the wall, then goes up over the ceiling and back down the other side to my router table and Kapex.

How high are the ceilings in that shop? Looks to be all of 20 feet. There's a lot of work expended in sucking all those chips and sawdust up 16 feet before you even start moving it horizontally toward the DC.

Your chart has a 4" duct and 400 CFM for a TS up to 16" with I'm guessing a 1/8" thick blade but a 5" duct and 600 CFM for a BS with a blade normally about a third the thickness of a TS blade. Seems backward to me.

Bob,

The chart comes from here; link given to me when I toured an industrial plant, and asked about its dust collection system:
https://astcanada.ca/industries-applications/woodworking/

The shop ceiling in the earlier photo is indeed very high, but its dust collection system was designed and built based on our provincial safety standards. According to the shop manager, the sound-proof room that houses the system didn't cost little in order to meet the audio requirements.

Snip.

Joel,

You sure you didn't copy and paste your tool wall photos from a woodworking store showroom?! [tongue]

Thanks for posting that chart [member=57948]ChuckS[/member], it's interesting. Two things I noticed that surprised me was the belt sander needing a 5" duct and the band saw needing a 5" duct.

I have a Jet JSG-6DC which is a 6" belt with a 12" disc. Both factory dust ports are 4" diameter.

And on the really stupid side is that before I made the 4" diameter dust collection housing for the Delta bandsaw, it came with a factory connection of 1.5".  [jawdrop]

Mine is also a 4" port on the bandsaw. But bandsaw dust collection, like the one for miter saw, is a tough spot. Rob Cosman came up with this idea:


For the record, Cosman's shop is VERY dusty, and I wouldn't want to work in that kind of shop without wearing a N95 mask all day long!

Can you provide a link? I'm having a difficult time trying to locate the forum. Thanks.

I think this is the site:

I recommend anyone who wants to learn more go to the Australian WW forum and study the DE findings on that site as it is the best source of information on the planet bar none. There are several sticky folders with solid proven data that can't be found anywhere else.

Cosman reckoned he had the dust problems solved when he moved pnto his new premises but apparently not.

Bandsaws are a real issue for a couple of reasons. Most of them have only one port on the cabinet and an air entry has to be created to allow make up air to enter the cabinet. If the entry for air does not exist then air flow stops dead so the dust piles up in the cabinet. There are some quite elaborate systems shown in the Oz forum but most go with a pick up on top of the table, modify the cabinet for air entry and hook up a line to the cabinet port. 2 x 4" lines equal 1 x 6" line or near enough.

You're right, just like an HVAC system, the volume of exhaust air is regulated by the volume of supply air. That's the reason I ventilated the zero clearance inserts.

This also made a huge difference in the amount of sawdust that was removed on a resawn board. Before this mod, when you separated the 2 boards sawdust literally poured out of the kerf between them.

But when the ventilated plate is covered it is blocked during cutting and does not flow air.

 

[ChuckM]

The blockage also happens on the table saw with a ZCI, and that's why above-the-table dust collection helps in that kind of cut. My SawStop blade guard (attached to a shop vac for max effectiveness) really shines in that...like a dust-free operation.

On the other hand, the ZCI on my Kapex does not impede dust collection.

Well yes & no...there's still enough air flow because of the huge reduction of sawdust that was trapped when resawing boards. I wish I had taken before & after pictures but the reduction of trapped sawdust was 5x to 10x...it was incredible. I also noticed the resawn boards and the saw blade were both cooler because the blade no longer had to resaw the sawdust.

Here's a good example of the air flow that still gets through, the 1st photo is immediately after sawing and the 2nd photo is simply opening the door. Notice the lack of sawdust buildup on the inside and on the lower wheel so there is significant air movement.

Cheese,
My throat disc has a wide gap and dust in the cabinet never is an issue because the 4"port takes care of it. It's the dust that I see above the table that bothers me.

My old solution was to place a box fan (with a filter) on the exit end, but it wouldn't work when sawing a long stock.

This is not mine but I thought it looked like a good solution to DE on the bandsaw.

 

[Michael Kellough]

Mini me’s comment on Cheese’s zero clearance insert makes sense but if it works anyway…

Still, it might be even better to add a hole in the zci kerf slot behind the blade.

 

[jeffinsgf]

Cheese (and others interested), here's my Cincy Fan dust collector with Donaldson canister filter.

 

[Michael Kellough]

[member=7266]jeffinsgf[/member] that looks so much like my old Delta portable collector. So Cincy Fan made them for Delta?

 

[jeffinsgf]

Sure looks like it. I have one of the Delta ones, too. They're identical right down to the mold lines in the drum top and the wording of the warning labels.

 

[Cheese]

Hey Jeff, thanks for posting the photo and the Cincy sales brochure. That photo really takes me back over 60+ years. When I was growing up my neighbor's father was a professional house builder and in his home shop he had one of those units. It sat on top of a fiber barrel that was the color of MDF. It was labeled as a Delta unit and this was in the late 60's or early 70's so they've been around awhile.

Also, the Cincy brochure confirmed the CFM values that Chuck posted earlier. Of further interest, Chuck's latest post also mentions Donaldson for their filter expertise.

The 1st .pdf is from the Cincy brochure and the 2nd photo is the latest from Chuck...notice the red underlined sentence near the bottom.  [smile]
