After having the top tip in Wood for my dust collection on my band saw, you would think I would learn.Tonight, I started sawing out TFT cars. Hooked DC to saw, and remembered to open blast gate. Cyclone came as required. After a few cars, I noticed an build up of saw dust. After finishing off 50 cars, I checked to see why DC wasn't working. Hose was still attached to blast gate, blast gate was open, and all others were closed. Took cap off tee and felt NO SUCTION! Started looking for problem. I forgot to connect the two sections of flex hose together. Stupid, Stupid, Stupid! Next 50 cars left almost no sawdust in, or on the saw.
