I'm looking to improve the dust collection on my contractor saw and
have been looking for ideas. I so far have found these:

What I would really like is something that allows for movement without
removal. I tried this one with little success:

Currently I have a huge box around the entire motor assembly attached
to the bottom of my outfeed table. It is probably not a goo idea to
starve the motor of fresh air this way so I am going to change it.
Anyone come across any better ideas?

Why change it? I don't have any dust collection on my contractor saw
at the moment, but will be adding it as soon as I get a cyclone. I
plan on doing exactly what you have done. It seems like the easiest
and best solution.

I intend to leave the the height and angle adjustment slots open so air
CAN travel through, and close off the bottom and enclose the motor.

I'm not sure how 800 or so cfm is going to starve the motor of fresh
air.

my solution is similar to the 2nd ref (Dizzy)

every saw will be different

i have the delta contractor from about 8 years ago

i fiddled with a back cover for hours to finally come up with a 2 part
system; a upper and lower cover with cutouts for the belt (elongated
to account for blade height adj) and cutouts for the motor mount. i
did not try to accomodate blade tilt. Like Dizzy I basically have
subscribed to the logic that I will rarely tilt the blade, and when I
do I will remove the covers and sacrifice the enclosed space. But for
90% or better of the time I'll have a tightly sealed unit.

I use a 6" port which is about 28 sq inches of area. Roughly I need
to allow 28 sq inches of open area to supply the incoming air. Like
Dizzy I stuffed strofoam into the side of my saw and with the back
cover it's pretty selaed. The only holes I have open are in the front
- tilt allowance slot for the height crank and the open space between
top and enclosure and misc cracks/holes in the bottom and back. And
of course the slot in the throatplate.

Use 6" sewer and drain and use 6" ports. see bill penz's site if you
question why or just do it and you will not be disappointed!!

My idea is to leave it like it is, but that's probably not what you're
looking for.

What are you using for a dust collector? When I put that cheapo $150 Harbor
Freight DC under my saw with a standard TS dust hood, it took all the dust
away without having to close off the motor side. What I now want is a way
to collect the dust from the TOP of the table and I'll have to rig up an
overarm guard for that.

But there ain't no dust ex caping from underneath that saw, motor shroud or
not. How's come you guys need to do that?

My experiance was the same. Delta contractors saw, Horrible Freight $150
dust collector. Put a 4" collector connection at the bottem of the saw,
between the upper portion of the TS and the stand. Left the ALL the openings
alone, read open. It does a really good job. The only way to improve it
would be over arm collection.

I'm using a homemade 30 gallon 'cyclone' powered by a shop vac. I was
surprised at how well this works using a flexible 4" dryer hose and a
rubermaid can.

Maybe If I bought a real DC this wouldn't be an issue but a one-car
garage shop that needs to house lawn tools, mechanics tools, outside
toys, gardening toys, etc. doesn't have room for more stuff. Besides,
I need more tools before I need a real DC.

"can cyclone" is cheap and easy:

' TS Vac
______| |_______| |_____
| _/ / | | |
| _____/ |
| |

Just put a 4" dryer elbow thru the lid and put the vac hole behind the
elbow. All that ends up in the vac is very fine powder in the filter
and the trash can fills up quick.

I have a Delta contractor saw. Delta has an accessory plate that goes under
the saw and a 4" connector. Then I made a back that covers about 3/4 of the
rear opening. Notches for the belt and the motor support. It catches 99%
of the dust that would come out the bottom. An overarm would get the rest
but I've not done anything about that.

I've posted a picture on ABPW

What is ABPW ?

The following article by Sandor Nagszalanczy, the author of
"Connecting Dust Collectors To Table Saws" would suggest that _if_ you
have a dust collection device (not a shop vac) you shouldn't be all
that concerned about the open back.

http://www.woodcraft.com/articles.as...fcode=05IN01RL

With that being said, I actually like the split panel approach shown
in the "Dizzy's Shop" article you provided. But if I were to
fabricate something, I think I'd be pretty happy with some sort of
compromise like maybe blocking off the static areas that are never
invaded byt the belt or the arbor. There is some logic to the school
of thought that says you have to allow for some airflow, and in this
case, I could see where the "vacumn" and subsequent airflow direction
being created by a decent dust collection system would probably
preclude any significant sawdust escape.
