The miter saw throws far more junk out the back than what goes into the tiny DC port (1.5" inner diameter). So I built this contraption which catches nearly everything, even at miter settings. Parts were scrap MDF, hardboard, couple of L brackets, and the 4" port from the Harbor Freight dust collection kit.
The sander was another mess, with no DC provisions at all. Enter this heater exhaust fitting I had laying around, a couple of wood blocks, an L bracket, and some glue. It is VERY effective.
The BT3100 dust collection isn't great; it drops a lot of junk out the bottom. So I put in a piece of hardboard with the large hood from the HF kit attached to it. A "y" fitting splits the 4" hose to this and the stock rear fitting. To catch the junk flying off the blade up top, I glued a shop vac floor nozzle to the top of the stock blade guard.
To connect all those overhead fittings, I made a splitter box from MDF scraps and 2.5" nozzles. It's not very aerodynamic, but since we're going from 4" to 2.5", it doesn't seem to have any effect. A 2.5" hose off a fitting right on the DC seems to have the same suction as the hoses off this thing. I used stretched picture wire to hold hoses near the ceiling if I wanted to allow the hoses to move around (IE, for the TS guard). For those that I want to stay in place, I just used U hooks.
For the HF jointer, I simply attached the large hood from the DC kit to the side. Unfortunately there's still a lot of fly-off from the top, so I'm going to attache one of the 2.5" nozzles to the guard and see if that catches it.
For the router mounted in the BT3100 table, I used 1" flex conduit to gather the dust from below. Top collection is via a 2.5" hose attached to the BT3100 router kit guard tube.
Work still to be done includes the drill press and the top of the jointer.
