I too use a shop vac, but keep the nose down low on the backside,eats most of the dust, but the larger chip's/shaving's fly towards me or down on top of the motor getting sucked into the fan. so I put together a shelf that cover's the rail, behind the rail,up the side's,down the front with a shelf to catch the byproduct[junk].then when it get's to piled up, I suck it up.
