Opinions on HPLV dust extraction on a cabinet table saw?

all i see is a forum link

AT THE LINKED PAGE, is that clear enough?

In my opinion there's two issues here, debris collection and health hazards. I don't think the sawstop is designed to collect the micron sized dust no matter what vacuum collection you connect it to.
I would think a mask and a dedicated air filtration for the shop or the area would be better suited. I just don't think there's any amount of sucking from either top or bottom going to capture it all/

I would be curious if any of the users with a larger dust collector that also have a particle counter would share their experiences / vs a shop vac and a cyclone

All those questions are answered in the link I provided with hard date to show the reasoning behind the result.

I thought the same. I think he means go read all those pinned posts there and the info is somewhere in there.

All the data and thousands of posts are at the linked page, it is a sub forum of the Australian WW forum. If you want to understand dust extraction you need to do some reading.

well sure that's fine but we're asking something specific. if you know the relevant discussion maybe you can link it here.

i don't think these machines are designed with health / micron level dust extraction in mind. they all look good in brochures and videos but there's no particle counters stats. there's no 3rd party certification, there is no independent testing. there's no requirement from the industry either so i can't blame the manufacturers.

Let's be honest. Perfect dust protection is impractical, if not impossible: who would wear an N95 mask all day long?

I've been to a few school shops with gigantic dust collection systems, and I saw saw dust all over the place. All those systems have to meet the relevant standards set by the province for schools, hospitals, etc.

Last week, I lunched with a woodworker, who turned 91 this year, and he said dust collection wasn't on the radar among his woodworking peers (most were gone unfortunately) in his days. All these years, he has had only one dust extraction equipment for his whole shop -- a shop vac. He had had a serious reaction in one project, a cedar project decades ago, but other than that, he seems to have suffered no ills despite his primitive dust protection.

Sam Maloof was a well-known figure for his rocklers, but also for working with little dust protection.

Of course, my 91-year-old friend and Sam are not good models for us to follow, but I wouldn't over-worry about dust if we follow the standard protection measures: such as capturing as much dust as possible at source, using air filtration during and after woodworking, and wearing an N95 mask when the first two measures are not considered sufficient. After all, we live in a (very) dusty world.

P.S. This school shop has two central dust collection systems; one, the larger, is shown here:

ferntree -why aren't you looking at a traditional high volume, low pressure dust collector?

Festool is in the former camp because none of their tools have a dust port larger than 2"  -with most being half that.
