Table saw vacuum - hole placement

I have an entry-level 10" Skil table saw I am adapting for better dust
collection. I am putting a flat panel beneath the saw (about 1" from
the blade at its lowest setting) and stand. This will cover the entire
bottom of the saw. I'm going to cut a hole to attach a 2 1/2" vacuum
hose. Where should the hole be? Dead-center of the blade? Ahead (front)
or behind? I'd like to aid the vacuum by shooting the dust directly at
the hole.

TIA!

I hate to rain on a parade, but you will not notice a lot of difference,
until you close off that huge hole in the back of the saw housing. The
Ryobi TS3650 has a housing around the blade, with a 2" dust port. Two
problems, the port was/is too small and the gap at the top the housing
allowed too much of a bypass for the air flow. Solution was to attach a
piece of visquene to the underside of table top with magnets and have the
side piece of the housing hold the the rest of the visquene. The result is
that the major air flow is down past the blade.

Dust has been reduced, but still have some.

Dan, something that hasn't been mentioned yet is the importance of
wearing a dust mask regardless of weather or not you manage to attach
your shop vac successfully. Likely it will catch a lot of the dust
produced but certainly no where near all of it. What is doesn't catch
is often the smallest particles that will be end up in your lungs.
You may already be aware of that but just in case your not it's
generally agreed that a good dust respirator is required whenever
using your saw or other fine dust producing equipment.

Sorry to be thick, Deb, but what the heck is "visquene' ?

Man, when I read this, I thought "how simple!". But after trying it,
I'm not too sure I like the results. The saw dust pooled in each of the
four corners. I'm thinking the "wind" from the blade pushed it there.
Now I'm thinking my plan for a vacuum is not going to work lik I
planned. I may have to go for a bag.

Very good point! I use a respirator mask - but then I have Asthma so
it's really critical for me.

Looks promising, however, the picture looks like the bag is at least
20" in height, but according to the specs, it's only 13 1/4". I bet
that would fill up fast.

Wow! Quite the setup. I ordered one of those collector bags. If this
does not work, I'll give your solution a try. Thanks!

One day I was in the lab complaining about the fact that the cardboard
box I slid under my Delta contractors saw to collect the chips was so
hard to slide out because of the leg tie bars. Light bulb lit up in
one of the new product team engineer's head and in a couple of weeks
he developed a bag that had a wireframe top. Included were a couple
of sheet metal angles that were screwed to the bottom of the stand top
plate. I took the prototype home to test it.

It worked like a charm, caught about 95% of the chips and dust, and
could be emptied in a few seconds just by sliding it out of the angle
pieces, dumping and sliding back in.

Went on the market for $29.00. Hardly sold any. Discontinued by now
I believe, or at any rate didn't fit the next generation stand.

That bag, and the drop down rear extension for contractor saw, also
about 29 bucks (I prototype tested that one too) were two of the best
accessories for a contractor saw I ever used. Neither sold well.

Since then I've seen all kinds of bags onthe market with snaps and
other attachment methods, none that are even close to that original
for ease of dumping. But, I guess they are selling because they
continue to be offered.

Go figure.

Temporarily put the piece in place and run a quick cut through the saw.
Look inside and see where the greatest amount of dust is and voila.

Some of the dust will pool no matter how you do your DC I think. However
if you had some slope in the mix it will help funnel everything to your
vacuum.

I have a Delta contractors saw. I built a hopper with a connection for my
Harbor Freight dust collector. Saw dust still fills in the corners and on
any horizontal surface under the saw. No way to avoid it as far as I am
concerned. The dust collector does a great job of grabbing the air borne
dust. You will not collect all the dust, no matter how much money you throw
at it.

I bought a rubber roof vent made for 3 - 4" PVC pipe from Home Depot
($5). Cut a hole to fit under your blade and screw it in, Hook up some
3" PVC pipe with a Fernco reducer to fit your vacuum hose and your in
business. You can see pictures of what I did here:

With a contractors saw, which I have, you will want to make a cover for
the back of the saw unless you have one of the 100 horsepower diesel
engine dust collectors:-)

So let it pool in the corners. It will build up only so far and the rest
will go into the dust collector. It is not possible to have the air flow in
such a manner as to be 100% effective.

No, it was not the wind from the blade that pushed it there, it is the lack
of air flow that did not allow it to be sucked out. The chunks of wood fly
and bounce everywhere. Remember, don't seal up the chamber so well that you
don't have air flow. To suck dust out, air must enter at the same rate as
it is taken away.
