I bought a dust collector from a full time cabinetmaker about 5 years
ago. I'm finally getting around to setting it up. This thing is not
like the Delta and Grizzlies I've seen. I got a great deal on it, but
it didn't come with any documentation or instructions. At the time,
the guy that I bought it from told me how to set it up, but I can't
remember what he told me :-(

Here are 3 pics of it, the first is a long shot, the second a close
up. The third just shows the model # and Serial #

It's got a 2 hp Baldor motor and the unit says Rayco's Mach. Mfg Los
Angeles CA. Model # 1274. I can't find anything on the net about this
thing or the manufacturer. All I'm really confused about is the 2
ports on the inlet side. Are they both for suction or is the bottom
one there to allow heavier chunks to drop out before passing thru the
blades? Any info, advice, experience you guys could give me, I'd
greatly appreciate it.
Thanks,
Mark

Thanks for the reply DPB, I should have finished installing this thing
before I posted my question. After I wired it up and turned it on,
it's obvious that the top port sucks air in and the bottom port blows
air out. I'm still not sure how this thing works. For instance, will
the bottom port spew dust or will that all end up in the container you
can see in the picture that is surrounded by the white felt sleeve. If
anyone has any experience with this type of dust collector, please
feel free to comment.

If you don't use both ports, you'll need to cover the one not in use.
Otherwise, there will be tendency for stuff to fly all over but mostly
it'll be pretty ineffectual w/ that big hole in the system.

As is, it'll put everything into the bag; ideally for a collector this
size you would feed the input into a cyclone separator and then only the
fines would end up in the air filter.

I would go to Home Depot and get a Fernco fitting that would connect my
inlet pipe to a PVC Pipe, and run the PVC pipe to a pre filter/collector
drum.You want as little dust and debris as possible to reach the
fan/filter.

On mine I piped the inlet to a large paper drum in the middle of my shop.

http://jbstein.com/Flick/dc1020457.jpg

Then I built wooden gates (I'm a woodworker after all) that go to
individual tools, mainly, Jointer, Table saw and Belt/disk sander.
Instead of building a cyclone I simply put 45° pvc pipe connectors in
the drum to get the air cycling around the outside of the drum, with the
DC connected to the middle of the top. The heavy dust falls to the
bottom when the air expands into the drum and whats left spins around
and falls to the outside of the drum. Cean air is sucked out the middle
top of the drum to the fan.

http://jbstein.com/Flick/dc1020458.jpg

This works great for me, and was, like me, cheap as all get out. All I
get is some fine dust, mostly from sanding, in my filter. You do not
need a giant bag on your collector using my method, a small filter is
about all you need. Maybe a hoover sweeper vacuum bag, something like that.

I had a connection failure to the newsserver originally when wrote this;
since I see Jack has posted another solution.

As Jack says, it doesn't need to be terribly fancy unless you're into
moving a lot of material altho w/ the air volume that is going to move
it'll take a more sizable container to be effective than his I think.

Anyway, there are any number of sites w/ info on making homebrew
cyclones as well as the commercial sites such as Penn State, Oneida,
etc., ...

I added this to my pre-separator http://www.cgallery.com/jpthien/cy.htm
and it made a big difference in how much stuff stays in the bottom of the
can. I suspect it's the reduced turbulence downstairs that keeps the
planer and jointer chips from going out to the filters.

There's a picture of the wall setup in the grouping at the link--'tis a
good-looking unit, indeed.

For OP, of course, w/ his independent fan his setup would be to feed the
outlet of the cyclone to the inlet of the fan (and I'd swap the two port
connector there for a single and put it on the inlet of the cyclone
instead assuming needed more than one main trunk line anyway). Then the
outlet of the cyclone to a waste container.

Would certainly be a far more serviceable system than the huge bag
collecting everything as currently.

BTW, I'd wager that puppy is pretty noisy; OP also may want to examine
building a sound enclosing area around it or if possible put it out of
the shop. Of course, if he's in a residential area and this is a
home-garage shop, that may not be feasible considering the neighbors...

It is indeed noisy. It's in my home garage shop so putting it outside
is not an option. I live in So Cal and the house next door is about
10ft away. An enclosure is a good idea. I don't believe that the guy I
bought it from had a cyclone container attached to it. I think he told
me the big stuff fell out of the the bottom port on the right side of
the unit.The rest went through the fan, but he said the fan was heavy
duty enough to not be damaged by the stuff that went through it. I'm
not sure how that's going to work. There's so much air coming out of
that bottom port on the right side that it's going to kick up a ton of
dust. I really appreciate all the help from you guys. I'm obviously
going to have to do some homework. First step is to contact the
company that Sonny found that sells this device. I'm hoping I can
obtain some documentation from them. The bulk of the material moving
through this thing will be dust from my cabinet saw, planer and chop
saw.

I can't imagine using it w/ one port open--I suppose one could connect
the lower port to a container but anything that actually falls out of
that port will have to be pretty good size. Only way I could see it
ever working that way would be w/ a small inlet airleakage in the bottom
of the leg/container.

Clearly that is _NOT_ the way the unit is intended to be used; if you
don't have and don't get or make a separator for it I'd suggest the
better choice is to block it off entirely if you're only using one port.

There's nothing large enough from a small planer or any saw that's going
to damage the impeller, that's true; it's simply going to be a nuisance
having to empty that large bag all the time instead of separating out
the solids and only collecting the fines.

I don't know what you expect the company to tell you? -- they're
certainly _not_ going to say the bottom port is a chip separation
exhaust port if that's what you're hoping for. Whether they've got a
separator specifically for it, maybe, but I'll wager you'll want another
wallet if they do...

Mark, that's not the same DC. This is a pic of a Rayco, not a Griz.

In this picture, the center Y ports are intakes, the left downpointing
port is the exhaust.

Porting the exhaust outside your shop (instead of catching it) will
fill the area with dust. In the city, that's usually illegal. In the
country, very messy. And if your house is downwind of it, it's
extremely unhealthy. If you pipe it outside and catch it there, it
will reduce the noise and create a real heating/cooling problem for
the shop.

No, same as the original posting; the Griz got into the conversation
because I simply posted a link to it as an example of what an
installation w/ a separator could look like (albeit it's an
integral-mounted fan instead of sequential as Spark would have to do w/
his to use a separator). The discussion then sorta' got onto at least
one other responder posting that he had a Griz, too, but it really was a
sidebar conversation.

The question of ports and purpose of same on the subject fan unit had
already been addressed earlier...

The one useful piece of data that could/would be interesting if they had
it would be the rated CFM and inches of H20 for the unit; that would
give you some info on what you'll have to use for ducting. Any of the
real lightweight stuff might well get collapsed by that dude if its
performance comes anyways close to matching its mechanical heft.

BTW, what's the size of those inlet ports? Looks like at least 6" if
not 8"? For the size of stuff you've mentioned, I'd likely look at
going to no more than a 5" trunk line and maybe even 4" as you're not
going to have enough chips out of a 12" portable planer to make the cost
of the large ductwork worth it (unless, of course, you're not
particularly constrained in that regard). That's big enough capacity
and large enough diameter that PVC would be a real static generator (it
ain't agonna' explode, not raising that genie here ), but it'll
surely be a shocker...and, if you've not yet priced it, you'll discover
that large diameter ductwork is a pretty penny.

Yes, thats pretty much the same as mine, except my ports are on the
side, and I have multiple ports for multiple tools.

I suspect it's the reduced turbulence downstairs that keeps the
planer and jointer chips from going out to the filters.

I think going from a small pipe to a large drum lets the air expand
rapidly with reduced velocity, allowing the heavy stuff to fall down.
The lighter stuff spins around and falls down because of the angled
inlet. The very, very light dust particles will get sucked up to the fan
and filter. I've never gotten anything in my filter other than powder
about the consistency of flour. My collector has a metal filter that
you simply take outside and wash out a couple times a year (in my case)

When I built my system, I had not done much research, it was way before

HP, SP and all that stuff. My collector is a bit weak, with a small
fan, small motor and stuff, but it works well, even though I run it
through a bunch (5) 90° angles and long distances, into a pre-filter
collection drum. If I had read that site that everyone seems to refer
people to, I would not have built my system. A lot of guys sharpen
their collective pencils and do the math, and come up with 100 hp
systems with .0000001 micron filters, 10 inch metal pipes and on and on.

If I had your system, (Your fan and motor) I would put one port out to a
central pre collection drum for my table saw, chop saw and basic vacuum
hose. The other port I would hook up to my planer with a large pipe, at
least 4", probably larger, but I'd try 4" first. I would think Planers
pump out long spirals of wood, unlike saw dust, which could jam up small
pipe. That would go to a large pre-collector drum, as planers will fill
up a drum in a hurry. If your garage is small, and room an issue, one
drum for all will do.

My suggestion is to use your imagination, and don't worry too much about
what the "experts" say.

I have the same unit. Bought it new years ago for a cabinet shop. I too am
looking for a users manual but only to calculate how high to mount it so that
the cloth sock fits on the 55 gallon cardboard drum without floating. The
machine is a workhorse. Both ports on the front are for hooking up separate
lines for suction. If you want a collection basin to catch large pieces of
wood then you should put one in the incoming lines but the impeller fans are
pretty spread out so it would have to be a pretty big chunk to cause a
problem. You would be much better off putting a screen over the inlet for a
floor catch tray to avoid pushing anything large in to it.
