I have one of their 1.5HP models, 4" intake, hooked to the planer with a home made 4" pvc draw tube slit about 1.5" wide, screwed to the output face of it. PITA. Planing poplar, which comes off in long strings, the first thing I had to do was cut away the large object grid in its intake port. Its standing next to a wall, and normally has a couple sections of dryer hose that run up to a 4" ABS elbow hanging from the ceiling so I can walk under it, comes back down & has a 4" ABS that plugs into the end of the draw tube, which is capped on the far end. Rated at 760 CFM, its no where near enough suck to keep the planer clean as it spits out small chips onto the front bad. The dryer hose, is that bend it once alu crap as I've been unable to source any of the old wire re-enforced plastic stuff locally. And its a shock hazard. I machined an adaptor so I could plug in the 2.5" hoses from the big vac, but it doesn't have enough suck to clean the floor if 2 of them are hooked in series so I can reach most of the garage floor. And too much junk on the floor to make it an easy sweep, something I detest doing because it raises more dust. I'd much rather suck it up at the source & be done with it. I've one of those $90 1HP GMC baggers you can hang on a wall, has a 4" intake, hanging under the eaves of the 12x16 shop building with its intake faceing a hole in the wall so I can hose it to the jointer & bandsaw. I had sewed up a big muslin bag about 20" in diameter and 10 feet long, with a dump zipper in the far end, hanging on screw eyes under the eaves. It has more suck than the grizzly. But the weather got to the bag last spring and its just blowing out in the grass alongside the building now. Composting in the grass I guess. :) I haven't spit out enough to cover & kill the weeds with it yet. Lasted about 6 years though. The zipper wasn't all that useful as the sawdust didn't make it to the far end, falling out of the air stream about 3 feet from the blowers exhaust port. Probably makes a great termite lunch though. :( Pix next, Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
