I'm getting more involved with carving and engraving using a
powercrafter air rotary tool. I need to do something about the dust.
I'm checking out various masks but I also have some questions about
portable dust filters and collection. I'm on a fairly limited budget
and before anyone suggests building my own, let me say that I'm not
very handy-- not very handy at all.
I was looking at the Grizzly portable dust filters, either the
Grizzly BENCH DUST FILTER-SINGLE FAN:
http://www.grizzly.com/products/item.cfm?itemnumber=G9954
or the Bench Top Dual Fan Dust Filter:
http://www.grizzly.com/products/item.cfm?itemnumber=G9955
Any opinions or other recommendations?
Also, what would you recommend for dust collection. Right now I'm
using the vacuum cleaner. But the shop vac I have is big and awkward
and the projects I've done so far have produced rather fine dust. Is
the vacuum cleaner a really bad idea?
Thanks for your help,
Kay

How about the $89 Harbor Freight 1hp dust collector, a $20
0.3 micron felt bag from Grizzly, + adapters to mate 'em?
That's about 1/3 the price of the Triton mask or 1/2 the Jet.
And it can be adapted to catch the dust at creation with a
set of 1/8" thick masonite panels

www.LeeValley.com , www.Harborfreight.com , and your local hardware
store all (should) have resuscitators for $20-30. I get the organic
vapor filters to cover dust and solvents/finishes.
>You all are very kind-- and patient.
Here ya go, Kay. Top(?) quality for bottom dollar, just
in case you're a fellow bottom-feeder.
Buy or recycle one swimmer's snorkel tube.
Buy a box of round HEPA filters (for resuscitators.)
Cut out a piece of cardboard the size of the screw end
with an ID the size of the snorkel tube OD.
Duct tape a filter to it and Voilà: a comfy resuscitator
which won't be interfered with by your full beard.
(Oops, maybe you don't have one of those, Kay.)
And you now have a spare filter for it.
Alternatively, find a PVC pipe reducer adapter which would
take the screw end of the filter and adapt the other end
to the OD of the snorkel tube. Instant breather. Just don't
breathe through your nose while using it. No plugs necessary.
Then again, regular resuscitator masks aren't all that
uncomfortable.

Skip the box...duct tape! Before I built my air cleaner, I used to duct
tape a filter to either side of a normal household box fan. It wasn't the
best thing, but it was pretty cheap.
I don't know what you are doing your carving on, but my wife uses a small
bench I built for her. In that bench I cut a square hole, a bit smaller
then the dimensions of an old push-stick litter bucket. I attached a dust
collector adapter to the bottom of the bucket, attached the bucket to the
bench and cut a piece of peg board to cover the whole mess. As long as she
carves over (or in the vicinity of) the pegboard, the dust collector gets
most of the dust. I would assume you could do the same thing with your
shopvac, although, like Morris said, it would be a bit noisy.

If you have pulmonary problems already, a HEPA mask my be the worst thing
you can do. In healthcare, the HEPA masks are provided only for those with
full pulmonary function, others are asked to perform other duties when the
case demands a HEPA filter.
See your doctor about this.

Hi All,
Thanks for your quick responses. I have a couple of more questions.
First, I'm concerned about the filtering ability of the dust filters.
For those of you who have portable dust filters, is it possible to
replace the 5 micron filter with a 3 micron filter? I looked for one
to use with the Grizzly but I didn't find it. Or, if you can't replace
it with an actual filter, can you attach 3 micron filtering material
in some way? Second, if I did rig up my own filter using fans and a 3
micron furnace filters, would I be able to achieve the same kind of
drawing power as the Grizzly? Third, I've looked at some masks and a
lot of them seem bulky and uncomfortable. But I found one that doesn't
look uncomfortable at all-- of course, it may be completely worthless,
too. Please, take a look and tell me what you think. Here's the link:
http://www.artwooddesigns.com/supplies.html
BTW, thanks to your support, I've decided on a new mantra: "I think I
can, I think I can..."

My most humble apologies:
I have no idea what the protocol is when you forget who you are

I may not know my name but I do know that I've appreciated the help.

OK... I think I've got it.
1) I can put together my own portable dust filter using a good fan and
hepa filters that filter down to the smallest particle possible. And I
can do it for a whole lot less than the cost of the Jet and my filters
will be more effective against the small stuff. My concern here is
finding a fan powerful enough to be effective. But I'll start hunting.
2) I need to collect the dust at the source before it ever gets into
the air. For instance, if I can rig up something like what Rob made
for his wife (earlier post) or the one that someone here posted a link
to.
3) I still need a good mask. I'll need to do some more research on
this. The Triton mask looked interesting but $270.00 would make my
crowbar limp, too... if'n I had one ;-)
You all are very kind-- and patient.
Thanks again,
Kay
Larry,
You just got me my new router (a refurbished Bosch 1613AEVS)!!! I
promised myself I would put my health first so I put the Bosch on the
back burner. Now I can do both.
Thanks very much!!!
Any opinions on the Bosch 1613AEVS are welcome. It'll be used mostly
for marquetry type inlay designs.

You folks have been a big help. Thanks for all the info. Since I
already have some health issues, I've decided to go with a Jet
portable dust filter. It's more money than I want to spend but for
$70.00 more (which is less than the cost of a prescription) it filters
down to 1 micron through an inner filter. Besides, if I don't need a
respirator mask with this it all balances out. Here's the link:

I posted about this last weekend, I got the air cleaner at Rockler's, the
dual fan that looks just like that Grizz except for the color. Paid $50.00.
Was in there yesterday and they still had some for that price. Their
advertised price on the website is $139.00. Maybe not all Rockler's have
them for the $50, but you might check it out if you have a store near you. I
used mine yesterday for some hand sanding on a small box and it seemed to
work quite well.

there are a dizzying array of filters available, from ones that are
basically a single layer of gauze on a frame to ones that have
activated charcoal and sub-micron filtration (for lots of money).
generic filters are good because they are cheap and come in standard
sizes. try the hardware store. get a fan that fits a standard
filter...

that's largely a function of motor horsepower. I wouldn/t worry about
matching the grizzly- it might not be enough for your needs, hard
telling. instead, make one that does what you need.
look, right now you're not filtering at all. money's tight, and
spending hundreds of dollars on a fancy factory made furnace filter
strapped to a fan will eat into your tool and wood budget. you don't
really know how good a system you need, but for sure you can strap a
furnace filter to a fan to see if it will work for you, and you can do
it for under 20 bucks, I bet. if it doesn't draw enough air, get a
stronger fan. if it doesn't filter out all of the dust, get a better
filter. filters and fans are very common items and come in a huge
variety of sizes, strengths and filtering efficiencies. you may have
to shop about a bit, but the parts won't be too hard to find.

I have a beard and glasses. I've never found a dust mask that works
for me. they fog up the glasses and the dust gets past through the
beard. I concentrate on methods that keep the dust out of the air in
the first place.

You mean "point 3 micron" (0.3u) filter. Standard filters have
30, 5, or 0.3 micron "holes" in them. 0.3 is the equivalent of
the HEPA standard.

You could build an adapter to fit the larger bag opening to
your smaller outlet if you have the little Griz. Just be sure
to make it airtight.

VERY doubtful. Box fans would catch some but not at anything
close to the CFM of a larger collector. Collecting the dust
at the source is the main reason for dust collectors, and fans
just wouldn't have the power in far too many cases.

_If_ the over-the-shoulder model has HEPA filters, it looks like a
winner since it wouldn't interfere with a face mask/goggles/muffs.
The other one appears to be a Taiwanese/Goldbergian nightmare.
Nose-plugs-on-a-stick? Har! When they say "nuisance dust", I'd

Yes you can, KT. To save money, try the little $20 Griz 0.3 bag
and build the adapter yourself.
The reason I'm answering these dust questions is that I've been

Note the size filtering those units handle? It's 5 microns, and fine
sanding/power carving creates much smaller particles. For your health,
you need HEPA filtering: 0.3 micron. It's the little stuff that is
so harmful. The cilia and our muscous membranes filter out the larger
stuff.
If you use the referenced filters, you might also want to duct the
output so it passes over a pan of water to trap more of the smaller
particles. It's also advantageous to wear a respirator with good
sub-micron filtering in addition to those traps.

Electrostatic filters won't work well in a shop due to the amount
of dust sucked through them. They'd fill up in an hour if they
lasted that long. The reason indoor vacuum cleaners now come with
HEPA filters is due to the fine dust being the most hazardous.

It is NOT for two reasons. First, it's a 5u filter, not 1u.
I quote "Filters 98% of all 5-micron particles out of the air"
Second, the post-filters like that work on dusty air that you
would be breathing while waiting for it to clean the air. It is
a -backup- to a good dust collection system, which filters the
dust AT CREATION. Portable filters like that are good to get the
dust back down after sweeping dusty floors and tables, or blowing
off a project.
Especially with pre-existing health problems, you want to have
clean air all the time, and that takes a sub-micron filter.
I'd recommend wearing a respirator with HEPA filters the whole
time you're in the shop if you go with that Jet portable as a
solution. Or tape a 5u furnace filter onto a box fan and use
that (the equivalent of the Jet unit) with a respirator instead
of the Jet. It's about 4x cheaper. ;)

Hey, that looks like a handy little gadget.
>Oh, and yes, it is available in the USA.
Grogs, I just looked at 15+ sites for the actual spec of
the AS/NZS 1716 standard and can't find anything other
than "conforms to AS/NZS 1716". How big are the holes in
those filters? 5-micron? The site doesn't say.
Never mind. I just saw the price ($270) and my crowbar
went limp.

well, none of us started life out very handy. hell, all I could do was
eat and poop when I was born, but look at me now... I can type and
everything <G>
point being, you can learn. this may not be the best project to learn
on, but it's not too bad. you can get a furnace filter (what the
grizzly units use) for 3 or 4 dollars at the hardware store and a
small box window fan... experiment, and do it for cheap.
if you can handle the crafts aspects of carving and engraving you can
do this. on the other hand, you may value your time and the finished
product of a factory made collector. just don't go believing that you
*can't* do it.
here's an example:

those might work for you. they'll probably work better if you have a
small fan at your back.

shop vacs are loud and have limited flow, which isn't ideal for
collecting dust that is dispersed into a largish volume of air. they
are great for collecting dust that has settled on a surface, or dust
collected at the source. if you're making fine dust and collecting it
with the shop vac, consider getting a filter bag for it. the really
fine dust that gets through the standard filter is the stuff that
harms your lungs the most.
in nice weather, work outside with a fan at your back.
>Thanks for your help,

Another option may be a unit such as the Triton powered respirator which has
double filters.

Oh, and yes, it is available in the USA.

Kay...
I don't do the kind of power carving you're doing (but that
doesn't keep me from offering an opinion :-)
The Grizzly products look OK - two fans will probably be more
effective than one; but you'll have to decide whether or not you
actually /need/ the two-fan model.
If you look at those products, you'll see that they're nothing
more than a box with a fan (or two) to pull air through a filter.
You say that you're not very handy; but if you're handy enough to
do power carving, then you're handy /enough/ to build a box to
hold a filter and a fan (or two).
If the vacuum cleaner does the job, then it's a good tool. If
not, then you need a better tool (this isn't not rocket surgery).
There are optional fine particle filters available for some
vacuums that provide HEPA conformance - this might be something
to check out with the manufacturer before you spend for another
machine.
I thought about using my ShopVac for dust collection and decided
against because of the noise level.
I believe that you can find free plans for shop dust traps on the
web.

I did it even cheaper by asking the plumber to save a squirrel cage
fan from furnace replacement and got 2 speed for zilch. Paid $8.00USD
for switch.

I posted the info a while ago and stored it in the google-izer. By memory it
takes two filters and down to 1 micron rings a bell.
Oh yeah, $270 is a cheap lung ya tightwad!
