Hi all
I will have a collector in my duct line when finished. It is a 33 Gal
garbage can with a plastic lid on it with the hoses passing in and
out.
I've been told to put Vaseline on the can, then put a sealer type soft
putty on the lid. Then set the lid down on the can. The Vaseline
will keep it from sticking.
I'm not sure about that. How would you do it?

How would dust "escape" a container under vacuum? <G>
The key here is to prevent air from leaking _in_, not out. I test for
vacuum leaks with talc. Turn on the suction, sprinkle talc all around
the seal, shut it off and look for talc inside the seal.

silicone bead on the garbage can lip. let it dry. make a nice soft seal. Weight
on the lid helps too.

Plain old foam weatherstripping.

You may discover that a small inner tube for a bike will stretch very
nicely around the top of the
trash can.... simply cut the plug out and sttetch it around the top of
the can...it will seal like a champ when you put the plastic lid on the
can... My children are all grown BUT I still found a few old tubes for
19-20 inch bikes in the shop...they work great...I also use one on the
DC itself to seal the bags...

I used some strips of foam weather stripping . The kind that has a adhesive
already applies to one side of it. The foam comes in several sizes and I
used one of the larger sizes that would make the lid fit tightly on the
garbage can by applying it to the lid. I applied it to the inside edge of
the plastic lid to make the lid fit tightly over the edges of the garbage
can and to the flat surface of the plastic lid that comes in contact with
the top rim of the can. I used different thickness of the weather stripping
on the sides of the plastic lid than what is used on the top of the plastic
lid. The top has a thin layer on it and the sides have a thicker layer on
it so that the plastic lid slipps snugly over the top rim of the gargage
can. By applying it in both places you can force the plastic lid to fit
snugly on top of the can. If it is snug (not tight) it will give you a good
tight seal and the plastic lid can be removed with out any trouble to empty
the gargage can. In use, the reduced preasure inside the garbage can will
pull the plastic lid down tightly onto the foam gasket you have created by
sticking the weather stripping to the top of the plastic lid. The foam has
good durability. I have been using this arrangement for about two years now
without any detectable wear to the foam. I am unable to detect any leaks
around the top edge of the plastic lid after the weather stripping was
applied.

I use a spray bottle with water to test mine.
I found foam weather striping sucked water right through it.

Try the soft, sticky, more rubbery foam. This stuff is more like an
automotive weather seal than foam packing material. The latter is
cheaper, the former is much better.

I used the self-stick foam weatherstripping and it works great. Test
for leaks using a burning stick of incense.
I used the same type of can and lid but used self stick weather seal (3/8)
around the inside edges of the lid. It works great and because it makes the
lid tight very little dust escapes the edges.

Look for 'closed cell' foam instead of 'open cell' foam. It's mentioned in
the fine print on the packaging on some of the currently produced
weather-strip.
Try to apply adhesive backed foam strip so that some part of the lid or
trash can top supports it when the suction is turned on and 14 psi
atmospheric pressure tries to push the seal into the can. For example, if
it is a home-made wood or mdf lid, the foam could be installed in a groove
or rabbet routed in the lid at the same radius as the top edge of the trash
can. Ideally applied, so that the suction force on the lid tends to squeeze
and hold the seal in place, I would be surprised if even ordinary open cell
foam allows significant leakage.
On my recently completed pre-filter can I used a strip of the hollow rubber
weatherseal in a routed rabbet in a wood lid, the nailing lip of the seal
strip being stapeled around the outside edge of the rabbet and a bit of
silicone caulk applied to the butt joint where the ends of the seal strip
meet. Seems to make a nice, secure fit to the metal can but I haven't
actually verified its performance yet (shop still under construction).
