Interesting Dust Collection Method

[Tscott]

Happened upon this video yesterday on Youtube and thought it was a pretty good idea for those of us who have multipurpose spaces. I've recently built a 4'x8' table saw rolling cabinet and it just so happens to have a large cavity already directly behind the table saw that I think will work great for this very thing. Hope you all find this useful.

I really enjoy Matthias' videos. That guy's always thinkin'... It helps that he has a good sense of humor, too!

Those little draft inducer motors are not really designed to move that much air, maybe 45 to 75 CFM depending on the static pressure.

One of the problems with dust collection on various tools is that you need very significant levels of airflow on most tools to achieve must "dust" collection, as opposed to "chip" collection which is easier.

Seems like it would be a pain to empty and would require a little improvement to make that easier but looks like something I will try soon

Agreed. You could easily design it with a door or slip fit lid to allow easy access and cleaning. For my needs, if I could collect 80% of the dust generated by the table saw and various other wood cutting tools I will eventually install in my saw table I'd be happy. My shop is an all purpose working shop so its more likely to see a dirty old tractor rather than a show car so being impeccably clean is not really needed. This seems like an easy DIY alternative to a full scale and expensive dust collection system that would require additional ducting to make work in my shop.

I'd clog that up in an hour.

This is a very informative and comprehensive link on dust collection:

After reading this a few times, I consider most of relatively effective system as inadequate. Its not until you start having respiratory issues that this stuff suddenly becomes important.

This. It takes significant pressure to truly capture the truly fine, dangerous dust. The link posted just above (ie. Pentz), is a great resource. I know the guy said he was checking his "Particle counter" but who knows what size boulders he was looking for. Furnace filters aren't going to cut it for the truly fine dust (that you usually can't see unless the sun is just right).

To effectively remove the fine dust on a table saw, you will need to collect at the blade guard and under the blade via the cabinet. What you propose may get most of the chips, and perhaps that's all you're after...but if you are looking at this from a danger/health perspective, you're going to need to step up to a true dust collection system that is WELL designed.

He was using a MERV 8 filter. That's sufficient for woodworking dust.

The video shows a Dylos DC1100 laser particle counter. Not sure if it's the Pro version, but the large particle size is 2.5 microns, and the small count is either down to 0.5 microns or something a little larger than that.

edit: I see that Matthias is using the Pro model. He talks about it on his site:
