The other day I was cleaning the filter on my dust collector and wondered why a fair amount of dust was passing through the dust separator . I thought cutting a window in the separator would give me a insight of what actually happens with the dust and found that the dust was just swirling around in a horizontal direction and it took a fair bit of time for the dust to exit and go into the barrel below .
The next thought was how can I speed up this process and get more dust into the barrel instead of passing through into the filter . I cut three little pieces of thin sheet metal and bent them to shape of little fins ( like seen in the pictures ) and fastened them to the separator slot from the bottom ( barrel side ) .I staggered the fins around the slot starting about eight inches from the beginning and about eight inches from the end of the slot .
The result was quite interesting as the dust would take only about a third of the time to exit the separator and the stream of the dust changed to a downward flow toward the slot and into the barrel .
I am very please how this worked out with a rather crude modification and will run the collector for a while like it is to see how much dust passes through to the filter and how full I can let the barrel get and decide based on the result if further modifications can be made to better the result . Sorry about the rather poor pictures .

Picture #3 is from the bottom of the separator ( barrel side )
Picture #4 is again from the bottom of the separator (barrel side )
Picture #5 a better view of the inside through window
Picture#6 just the fin and my buddy (see more pictures of shape in comment 20 below
