dust collection 2 stage ??

I have a delta dust collector one stage that was converted[ by 30 gal. pail top and 2 hoses] into 2 stage
the question is I have changed the 30 gal pail to 20 gal. for size savings and vac seems to be less suction . Seals seem good is size a factor?
Thought smaller may have been better??

The only disadvantages I can see to a smaller bucket are less room for the chips to drop out of the air swirl, and of course, less room in the bucket, so you have to empty it more often. I have my DC set up with a Rubbermaid garbage can for the cyclone stage, and it seems to work quite well.

There is one issue that you may want to look at, and that is how many elbows or 90 degree turns you have in your airflow. The fewer turns the better. You lose a little bit of pull through each turn.

I noticed an "elbow"of sorts under the lid . It's removeable and can go in either side [close to work or close to collector] not sure which way it works better -

I believe that the best location for the elbow inside is close to the work. The material comes out with the airflow, swirls around in the bucket, and much of it drops out before the air gets sucked into the port going to the dust collector.

I could be wrong, but it seems to work. Nothing wrong with trying it the other way to see.

I have a 4 inch DC, and have noticed the odd time when the elbow inside the cyclone cannister has fallen off. It really reduces the effectiveness of this part of the system. Other than that, the cyclone works terrific. I often have the garbage can full of shavings before I realise it.
