All the experts say, you want to use large ducting for the trunk line and try to maintain that circumference all the way down to dust port. Some when the duct drop from trunk, I will still use 6 inch duct dropping into a reducer (6 right to 4 inches) and then finally right into the dust port.
So hear is my question. Can I purchase all the ductwork at a Home Deport. For example a 6 inc steel duct that is 5 feet long is only $8 which is approximately 10 times less than the ones sold on the cyclone manufacturer’s websites. Even the Y-tube connector are about $6 versus about $50 on the cyclone manufacturer’s web site. Other than those cool blast gates that I can’t really find at home depot, it appears that I can save TONS of money by getting a Grizzly Cyclone and purchasing most of the ducting at a big box store, right? Or am I missing something here?
Lastly, I wanted a system that I can turn on and do woodworking rather than moving multiple shop vacs around to each tool. Since I only run 1 machine at a time and my shop is small (longest distance from cyclone to furthest tool is 11 feet of trunk line). All the other tools are within 6 or 7 feet from the Cyclone. That being said, Can I get away with one of the cyclones that are listed at 775 CFM. I know Bill Pence’s website recommends about 800, but he mentioned that he rounded up. The 775 should be enough for one tool as long as the ducting is 6 inches and I keep the blast gates closed for th other tools. Does this all sound correct. I showed my shop drawing to one of the other cyclone manufacturers and they had me ordering a 3 HP cyclone (my shop is only 10 feet by 17 feet = a mere 170 square feet). Comments and advice please. I would rather spend my money on good hardwood than excessive HP and systems that I don’t need. Thanks in advance for all your responses.
