Topic tags/keywords: dust collection shop vac dust vacuums resource

Right now I’m using a shop vac connected to either my TS or my chop saw to collect dust. It works all right most of the time, but I wish it was better. Seems to be better with the table saw than my chop saw. I’m not sure if these quizmos out there will suck up more sawdust or just simply prevent the dust that is sucked up from going to the shop vac and clogging the filter.

The two I was looking at were the the Oneida at Woodcraft:

Or the Dust right at Rockler:

http://www.rockler.com/product.cfm?page=31104&Max=999

Anyone now which one works better. Right now the Rockler sits at the winner for being 10 bucks cheaper and appears to have a lower profile!

Thanks again!

Neither will increase the volume of air your vacuum will collect with a clean filter.
The Dust Deputy will separate from the air stream and collect more of the fine dust that would otherwise clog the vacuum’s filter.
The Dust Right will capture less of the fine dust, but will hold more of the larger chips due to its bigger container.
For my money I’d rather have the Dust Deputy, but I’d put it on a larger drum.
Chop (miter) saws are notoriously difficult to capture flying saw dust from.
About the only solution for a chop saw is a good hood behind the saw and a dust collector.
When comparing what ever modifications you do to a vacuum based system to the cost of a true dust collector you have to realize that a dust collector, even the $149.00 Harbor Freight 2hp unit will collect about 8 times more air.

I have the Harbor Freight unit and it works great. If you do a little research and collect the manuals for various makes of DCs you’ll see that quite a few of them suspiciously resemble the HF unit. It is closer to 1.5 hp than the advertised 2 hp. It beats the heck out of a shop vacuum. Get a 20% off coupon and you can get it for around $160. I’ve heard of some folks getting 25% coupons though.

Agree with crank49, even the cheapo HF dust collector is going to outperform any shop vac for the volume of air used. If you want really good dust collection on a chop saw, you’ve pretty much got to use some sort of external collection device behind the saw (which would have to be connected to a dust collector… to many cfm required for a shop vac). Add on a Wynn filter for about $150 and make a DIY Thein baffle, and you’ve got a pretty decent dc for about $300. I wouldn’t count on it to power ducting for an entire shop, but it’s definitely enough for a single machine with a short run of flex.

A shop vac is still better than nothing though. As crank49 mentioned, a separator won’t increase airflow vs a new filter; in fact, it reduces it slightly (due to the static pressure increase). What it does, though, is keep a majority of fines from reaching the filter and over time, suction will remain relatively constant. If you let all the dust get to the filter, suction will really suffer.

If you stay with the shop vac, I’d suggest looking into a heap filter for it. If you’re using a stock filter, it’s just pumping a lot of the dust right back out into the air.

I have the Rockler and it works well enough, but from what I read the dust deputy performs better. One thing I absolutely HATE about the Rockler unit though, is that it’s very prone to tipping. Should that happen, bye bye cyclone action and all the stuff you’ve collected goes straight to the vac. It bugs me that they advertise the thing as being very stable due to having 5 wheels, when in reality the truth is anything but. To counter this, I put a cinder block into the bottom of the container. Works okay, but it’s still possible to tip at times. Also kind of a PITA to empty as a result because of the added weight. I don’t know how well the DD with the bucket works in this regard.

BTW – the link you posted for the HF DC is the unit people talk about.

Thanks gtbuzz-

If guys are having good luck with the HF DC than maybe I’ll save my money for awhile, using the shop vac a little longer until I have enough funds for the HF one.

I invision having the dust collector in between the two tools I use the most, which is my chop saw and TS. The problem I think with the chop saw is that it’s hard to get the vacuum close to the blade. I’ve ponder if I would get better collection sticking a smaller wand of some sort closer to the blade. Like maybe one seen on home vacuums.

The HF collector is always on sale if you get a Handyman, DIY, Wood or Popular Woodworking magazine, you will find the collector in the full page HF ad for $139. Sometimes you can get them to take the 20% coupon off of the ad price. Depends on the store.

I have the Dust Deputy/Shop Vac combo. It is hooked up to the miter saw only for now. On the other side of the shop (garage) the HF dust collector is hooked up to a manifold that lets me collect from the table saw or any other tool via a 4 inch flexible hose.

A planer and/or jointer will generate a lot of chips. The HF machine excels at this type of dust collection.
However, a chip pre separator with some sort of Thein separator will help to reduce the chips being sucked into the fan and blown over into the HF dust collector.

Keith those are magazines that have the coupon for HF. Wood or popular is Popular woodworking I think. Toolie almost every thing at HF is always on sale and you can always use the coupon to make it even cheaper.
