I have a DC question, and didn't try to google yet, I'm kind of tired
tonight and just not in a googling mood. I have a Delta 50-840
collector and it's hooked up to a Unisaw, DeWalt 735, and I'll be
getting a DJ 20 soon. Is it good enough to just leave it hooked up
directly, or should I be using some sort of a separator? Since it does
take in it's fair share of chips from the Uni, I wonder if they can
damage the DC? I'm really not up to speed yet on DC, so please excuse
the newbie question. And besides, I'm doing my duty in trying to offset
the idiot poster of late. Many TIA, Mark L.
I gave up trying to run my DC without a separator. The
inlet has a ring in front of it that kept getting jammed up
with wood chips, especially when using the surface planer.
With a garbage can separator, I NEVER get any clogs! For my
shop, it's a must have.

The separator, assuming you empty it often enough, does
a great job of keeping big stuff from dinging the impeller.
Also keeps shavings/curlies from hand planing from
clogging up the DC's intake.
Another potential tip - if the unit you have has a Y inlet
to allow two 4 inch dust lines to be connected at the
DC, orient the one you won't be using down and the rubber
plug left on. If an impeller dinger gets through the
separator and hits the impellar it'll often drop into
the unused, downward pointing port - where you can
get it without having to reach in and find it. NEVER
reach in around the impeller unless you've personally
unplugged the DC or verified that the unit's unplugged
JUST prior to reaching in. One more thing to remember
it can hurt you.
Oh, and ditch the dust bags that come with the unit
unless you got the 5 micron option, 1 micron being
preferable. 1 micro oversized felt bags work pretty
well. The big stuff that the stock bags catch isn't
what will mess up your lungs - it's the very little
stuff that'll screw you up.
Here's a great site with plenty of useful info on
I've got a trash can separator in the system simply to catch the big stuff
that gets sucked in..., e.g., cutoffs from the cabinet saw and band saw,
and things that the kids suck up off the floor when they clean up for me.
(The kids like hauling that 4" hose around and sucking things up... way more
cool than the little shop vac. ;-) ) My system is piped in with 4" spiral
and uses a Delta 50-850 1.5 HP with a Woodstock International trash can lid.
The system pulls most of the stuff right through the trash can an into the
bag but the big stuff drops out. It's the big stuff I want to keep out of
So what non-wood items have you sent past the impeller so far?
I've a Jet DC with the cannister filter and wasn't able to hit the STOP
button before destroying:
aluminum soda cans;
plastic yogurt containers;
the pot metal Delta 14" bandsaw table insert plate.
(Pulled out of the chip bag a little dinged and bent but otherwise, it
and the DC appear to be OK.)

Nothing... I had the trash can on the system pretty much from the beginning,
even when I had a 1 HP Delta dust collector hooked up. The stuff that has
hit the trash can includes rags, paper towels, cut-offs, sand paper, a
plastic cap off a spray paint can... The kids don't discriminate when they
The garbage can with the separator top does a good job. It will catch
large pieces and tools from reaching your DC. A little better than
that is a cyclone. I made one from a garbage can, some galvanized
piping and elbows--works great. Later, I installed a small Plexiglas
window in the can, halfway up, to know when it's time to empty it.
Makes you wonder why they don't make more of the kind I have - impeller unit
on top of the can. I've always thought it's ideal for the small shop.
Rolls, doubles as a vacuum, and never jams an impeller with a stray chunk.
Now if they could only find one that could keep up with a lathe....
I have the exact same model DC. I use it on the TS without a
seperator, but I do have zero clearance inserts. I don't recall ever
sending a piece of scrap through the DC from the TS.
When I first got my Delta Plane (22-580), I was so excited to try it
that I ran a board through it as soon as I got it set up. Then I saw
that the hose to the DC (I have a clear hose) was completely clogged
with the shaving.
I had bought all the fixings to make a seperator, but didn't have the
time/need before. I can't run the planer without one.
I never use the seperator on the jointer either. I guess its shaving
are fine enough that they aren't a problem.
The 50-840 has a cross over the intake and I think the planer shavings
are just too long to pass through them smoothly, thus the problem.
By the way, I routinely check the impeller and it doesn't have any
knicks in it. Thought that was worth mentioning.
