If there are no leaks and since the planer is a good distance from the dust collector and half this distance is 4” flex hose, my guess is that air flow is severely compromised. If so, then the large planer shavings slow down, lose downward/outward momentum, stick together, and form a shavings dam as the shavings approach the drum. The flex hose connecting the cyclone to the drum appears to be about 12” long, which could further slow the swirling air.

The easiest way to increase air flow inside the cyclone is to open another blast gate; in addition to the one at the planer. This may be all that is required to fix the problem since more air can enter the cyclone.

Additionally, increasing the distance from the planer back to the cyclone with larger smooth walled pipe could increase airflow within the cyclone. If this is not possible and then replacing the 4” flex hose with a smooth walled 4” flex hose could reduce static pressure and thus increase air flow.

Modifying the flex hose from the cyclone to the drum by inserting a length of smooth walled pipe and shortening the flex hose could also help. This modification may be enough to keep the air speed high enough to eject the shavings into the barrel.

As a point of reference, shavings and dust in my collection drum form an inverted cone where the shavings pile up around the wall of the barrel. My belief is that this is an indication of air flow within the cyclone and inside the barrel; the deeper the debris cone, the greater the air flow.
