In the last few weeks/months/ somebody had a link
to a guy building small/medium cyclones to be used
with existing DC setup's.
It's not the Bill Pentz(sp) site but somebody else.
Anybody remember where that site might be ?
If you buy this thing, you MUST report back to the wreck!! It looks
too good to be true for the price he is charging. Based on what I have
read by Pentz, I don't think the average 2hp or less DC would be able
to be very effective at getting the fine dust when hooked up to this.
I ask the same question, why do you say that ???
If it can handle a planer, a table saw will not
generate 1/3 the debris, a 15" planer does.
If you match the cyclone up with a decent dust collector
with proper bags, what's left ???
A table saw will generate less mass but what the saw generates is much
finer. The finer the dust the more velocity a cyclone needs to take it
out. The idea is that with a good cyclone very little gets as far as that
Look at it this way. With a jointer the actual action of
the cutting is throwing the chips down a chute and it's got
no where else to go. With a table saw it's got all kinds of
places to go. Some goes towards the blow pipe and some goes
elsewhere within the cabinet.
The trick to making an inefficient collector better is
having the inlet as close to the source as possible. In the
case of the table saw you want it right at the front of the
blade, in a vertical position below the table and
behind(ish) the blade in a vertical position at the top of
the table. This way you can rely on the natural order of
things to fling the dust into the pipe.
I am thinking about it, because of a shop design, I can't
have a big Oneida. I am looking at the newer Delta units
The Oneida folks really want you to have a ceiling mounted
trunk line and my ceiling is 12'8" and even the guy at
Oneida admitted that it was a wee bit high for their
commercial 2hp unit.
The next step up is the 3HP and that's quite a step in price.
So, my basic plan is get the two bagger from Delta (50-763)
and then I got to thinking about how bad I hate to empty
those nasty bags and I remembered this guy's cyclone.
He started out with a small unit but now has one with a
bigger intake and exhaust and for the money, it's really
starting to look like a plan.
For well under $1,000, I can have 3hp DC with cyclone.
I have a used Torit sitting out in the yard for sale. It has a 3 phase
motor that needs new bearings. Or it needs a single phase motor for
residential use. It would be great for someone who does not mind the
noise of a larger vacuum system. It is a model 20-5FB-255 which has
four 11.5x70" flter tubes and uses 2 55 gallon metal drums for chip
2500cfm at 7142 fpm 5" ext s.p.
2250cfm at 6428 fpm 6.6" ext s.p
2000cfm 5714 fpm 8.4" ext s.p.
1750cfm 5000 fpm 10" ext s.p
It moves a bit of air.
8" inlet, 5 hp Baldor motor 3600 rpm, 15x3.5" fan
Negative is that it requires 131.5 inches (11 feet) minumum to install
and a bit more if you want to remove the motor for any service. i
would have used the thing at home but when it was in the shop I built
a sound box around the bags to knock down the noise. Fresh bearings
would have quieted it a bit but it is nowhere near as quiet as a Jet
650. On the other hand it does suck a whole lot more than the little
I am here. Atlanta. The shipping weight is 733 lbs and the net weight
is 614. Since the unit was install back in 1988 think net weight plus
2 or 3 pallets. Full disclosure and pictures if you are interested.

I haven't done the complete read on his little site but
I wonder how did you come up with that?
If I do in fact get one, I will do the full monty on the
critter right here.
I can't believe the worst design in the world wouldn't
get "most" of the stuff while the bags would get the rest.
I am surprised no one else has given this a serious look.
OK, speaking from one WITH close to the worst - or at least, cheapest -
design in the world...
I use a 55 gallon fiber drum I picked up out of a roadside ditch. Cut a
plywood circle with a routed groove to fit onto the drum lip (I drove up
and back scanning the roadside for the snap-latch fiber lid with no
luck) . Two holes are cut in the ply - one in center and one near the
edge. Cemented in DWV pipe that fit my 4" DC hose. The pipe near the
edge has an elbow inside the drum that's aimed toward the drum wall. The
center pipe extends about 8" into the drum.
Connecting the center pipe to my Jet 1100 w/canister DC and the elbowed
pipe through about 15' of 4" hose to my table saw, band saw, jointer or
planer will catch practically ALL of the dust and chips. The clear DC
bag ends up with only a small amount of particles swirling around over
extended periods of DC-ing.
Given that my setup works so well, it's hard to believe that something
that actually has the shape of a "real" cyclone collector won't work
equally as well or better.
