PFG, Picture Framing God

Neil asked about my dust collector in a different thread. I thought that maybe the topic deserved a thread of it's own.Did you build the dust collection for the Pistorius?
One of the shops that I work for now has a Pistorius with NO dust collection system.
I did build it but I'm not real happy with it. Here are some pictures of the original build with some explanations.
The dust collector is a basic harbor freight 2HP collector. http://www.harborfreight.com/2-hp-industrial-5-micron-dust-collector-97869.html. It works just fine. The problem is that the Pistorious is not built for dust collection. The dust collector is better than not having one but nowhere near as good as a machine designed for dust collection would be.
About 15 years ago I built a 2 stage dust collection system for a 15" Delta planer. That one worked just fine. I used the same garbage can setup as shown below and the intermediate stage did an excellent job of collecting planer shavings. Very little actually made it to the dust collector.
In the build below, the intermediate stage is worthless. About 99% of the dust just passed straight through the garbage can and into the dust collector. For those not familiar with a 2 stage collector, the purpose of adding an intermediate state is to collect the majority of dust at that state because emptying the garbage can is easy and removing the dust bag and putting it back on the dust collector is a pain.
In any case, since the intermediate stage was worthless in this setup, it has now been removed.
As you can see in the photos, the back of the saw had been closed with a piece of sheet metal. This was probably done for a previous dust collector. With the Pistorious, the top is completely open and the bottom is open also, so the piece of sheet metal is of no use. Actually it is a PITA because you need to get into the back to removed those droppings that don't make it down the chute.
Pre dust collector, most of the dropping made it down the chute. After the dust collector was installed, the vacuum was just enough to suck the droppings just a bit so maybe only half made it down the chute and the rest dropped down to the bottom of the saw. A few are even sucked into the dust collector. So the saw needs to be open to periodically cleanup all the droppings. I have built the chute a couple of inches higher (as high as I can without interfering with the blades) with aluminum foil duct tape, but still a lot of droppings don't make it down the chute.
The bottom line is that it is better than not having any dust collection but no where near as good as it should be.
There are a couple of things I might try later. One is trying to place some kind of cloth hood over the top to improve suction there. Another is trying to seal off the bottom and back with something removable so cleanup can be done.
If any one else has had some success with dust collection on an EMN Pistorious, I would like to hear about it.
