Tom Cancelleri Posted March 25, 2016 Author Report Share Posted March 25, 2016 Is it spiral pipe? If so you should be fine. I can't remember what gauge mine is but it was either 24 or 26. It's standard straight pipe. They rate it for 5hp and lower. Sent from my 831C using Tapatalk Quote Link to comment Share on other sites More sharing options...
drzaius Posted March 26, 2016 Report Share Posted March 26, 2016 I used 8", 26 spiral & it is very strong. Just no way it will collapse. But there are 2 kinds of spiral (can't remember the terms). There is one that's very smooth inside & another that has ridges, which you don't want. Quote Link to comment Share on other sites More sharing options...
shaneymack Posted March 26, 2016 Report Share Posted March 26, 2016 Mine is just standard 6" 26g. I've had no issues. I've even started it a couple times before opening the blast gate and nothing happened. Sent from my SM-N910W8 using Tapatalk Quote Link to comment Share on other sites More sharing options...
rodger. Posted March 26, 2016 Report Share Posted March 26, 2016 if you have a 5" exhaust port, how overwize do you drill the hole? Quote Link to comment Share on other sites More sharing options...
Tom Cancelleri Posted March 26, 2016 Author Report Share Posted March 26, 2016 Well that was a giant pain in the ass. I drilled my center hole through the wall and through the house. It's just next to the stud so I could screw 2 of the vent cap screws to it. I cut a series of 2" holes with my hole saw and knocked out the bulk of the waste. Then went at it with my Carvex. I used my battery powered angle grinder on the aluminum siding to expand the hole to fit the cap. That fiber board crap they use that is the consistency of dried cow sh%t is awful. I installed some screening behind the flaps to keep things out. Sent from my 831C using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tpt life Posted March 26, 2016 Report Share Posted March 26, 2016 I had to go back and read the other thread too Steve. Seems one exhaust for the DC and a separate dual use fresh air/fume exhaust. Quote Link to comment Share on other sites More sharing options...

Tom Cancelleri Posted March 28, 2016 Author Report Share Posted March 28, 2016 I temporarily wired up the cyclone to test it out and make sure my stuff was good for the upcoming permanent wiring. All I can say is WHOA! This thing sucks so hard. Also, I realized that the previous owner's problem wasn't that the CV1800 wasn't powerful enough to keep up with his tools. His problem was his setup, he had the impeller wired up and spinning the wrong way, which was making the airfoils less efficient and creating additional resistance and slow down of the air. I rewired the motor in the box to spin the motor in the other direction and there was an immediate difference on how much more air was getting pulled into the cyclone. Inside the shop, the cyclone is 77 decibels which is actually pretty good, though it's annoyingly loud still. I will need to figure out a way to quiet things up a bit. Outside the shop is another story it's pretty loud out there as well, and I don't think I'll be running the cyclone late at night. Maybe once I have the rest of the ductwork done it'll be a bit quieter. Outside sounds like an airplane taking off. I really wanna hook it to my machines and make as much dust as humanly possible Ugh Spring is here and pressure washing the siding is becoming a reality. I'm thinking maybe make a box that doesn't violate HOA rules that can act like a silencer and muffle some of the noise. Maybe try to get rid of some of that machine noise that's leaving through the exhaust vent. Quote Link to comment Share on other sites More sharing options...
..Kev Posted March 28, 2016 Report Share Posted March 28, 2016 It does seem loud but, it's hard to tell from the video. Suggest turning it on and doing a walk about close to your neighbor's and see how loud it really is. Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted March 28, 2016 Report Share Posted March 28, 2016 Plant a shub in front of the vent. Hides the hole, diffuses the dust, and muffles the sound. 2 Quote Link to comment Share on other sites More sharing options...
tedfmcm Posted March 29, 2016 Report Share Posted March 29, 2016 Could also make a baffle/muffler box outdoors? something like this: Quote Link to comment Share on other sites More sharing options...
drzaius Posted March 29, 2016 Report Share Posted March 29, 2016 Mine isn't vented outside, but the collector is in a separate room. The return air duct to the shop has got a bend & a dog leg in it & it's lined with duct insulation. Very quiet. Quote Link to comment Share on other sites More sharing options...
Tom Cancelleri Posted March 29, 2016 Author Report Share Posted March 29, 2016 I was thinking I might try spraying the exhaust pipe with Boom Mat, which is an acoustic sound material. The problem right now is the exhaust pipe is carrying the sound of the motor through it creating that harmonic vibration that's being exhausted.

Popular Post Na1han Posted March 29, 2016 Popular Post Report Share Posted March 29, 2016 I've looked into trying to muffle my cyclone but never ended up pursuing it. Mine is mounted in another room and I wear earmuffs anyway. Anyway if you want to give this a try it may work fairly well and not restrict flow at all. It's called a Helmholtz chamber and its used to dampen a specific frequency. On your Clearvue the fundamental frequency is apx 345 Hz (3450 RPM / 60sec/min * 6 blades on impeller). I've verified this with my cyclone using a free FFT app on my phone, it shows a large spike in Db at 345 Hz. It's possible to design a Helmholtz chamber to dampen that frequency. Below I included some calculations on possible chamber sizes. Basically you would T this chamber off your metal exhaust pipe, it would have a neck and sealed chamber attached to the neck. The critical dimensions are the neck length, neck diameter, and chamber volume. I designed it using PVC sizes because that is what I had available. Like I said you can give it a try, I haven't had the need to yet. I can't promise anything but we use Helmholtz chambers in the automotive industry on air intake systems for engines and they are quite effective. Edit: noticed a typo in the title of the second table, it should read "Canceling 57.5 Hz 1st order frequency" 3 Quote Link to comment Share on other sites More sharing options...

This sounds like the easiest/cheapest thing to try up front. I wrapped the hvac pipes that run through the laundry room with an insulation wrap and the sound dropped a lot to mostly just a low frequency hum.

Tom Cancelleri Posted March 29, 2016 Author Report Share Posted March 29, 2016 I may have figured out the layout that gives my tools the ability to be stationary with maybe an occasion when I need to move my router table around a bit. This gives me 8 feet infeed/outfeed at the table saw, jointer, planer, 20" bandsaw, and about 7 feet at the drum sander. While the big bandsaw has no outfeed, I thought of a few things I could possibly do to make that a reality. I was thinking a flip down ledge from the wall on the other side of the steps, just to the left of the lathe. This layout also groups the big chip makers fairly close to the dust collector. It will require that I run dropped outlets from the ceiling for the planer, drum sander, and table saw. 1 Quote Link to comment Share on other sites More sharing options...

Yes, all the measurements are correct for the shop size and tools are all 3d warehouse models, and are the size of my tools with maybe a couple of small variances here and there.

Tom Cancelleri Posted March 30, 2016 Author Report Share Posted March 30, 2016 Don't mind my horrible hand sketch for laying out duct work. I wish there was a good duct plugin for sketchup that wasn't expensive. 45 degree bends everywhere. No harsh 90s, and a fairly short run compared to previous layouts.
