But here is what I did and you might gain some help in your thoughts with your design.
I used 2 pieces of a/c flex duct a 300 inside a 600 as a muffler to duct my exhaust outside and I found most of the noise come straight through the elbow on my system on the outlet of the DC. I added more sound deadening around the outside of the elbow and around the impeller housing to cut the noise down.

I have bought the 90degree transition, but I think I am going to have to modify it to be straight. Thanks for the tips on the sound deadening, might be an option to make some mods for the exit if I have it straight out.

What did you use for sound deadening?

I use 150 mm foam mattress I found that had been tossed out.
The photos explain more. Not in the photos is the foam wrapped around the impeller housing note not the motor.

Thanks rusel. Your photos also answered one of my other questions regarding having the exit and input on the same side!

Did you use store purchased bin or did you build your own?

"Did you use store purchased bin or did you build your own?"
both...mine was to big and heavy, the shop one, was a small metal garbage bin. You have to make sure that there airtight, I just glued up the all the seams.

Thanks Rusel.

So today the aircon was fitted. Tested it out by sitting in the shed doing some programming for my fathers milling machine automation. Very nice indeed.

The CV1800 also turned up today (Thanks Stephen for the personal delivery!). The body of the cyclone is much smaller than I expected even after measuring it all up in the shed beforehand. Unfortunately the curse of paid work is upsetting my leisure time and I have to spend the next few weeks in the real office, so there will probably not be any progress on dust collection in the short term.

Some more progress today. Cyclone assembled and installed.



Miscalculated something as its sitting 2 inches higher than it should be. Not to phased though as I have a bigger drum to pick up from my father. Will need to build a stand for the filters though. Also going to install a separate 15a circuit for it.

Next step is plumbing. Picked up a bunch of 150mm dwv from masters. Just need to go purchase some fittings now.

looking good

Another day in the Shed today. Decided to move the 6" pipe up higher to keep the mezzanine clearance at a maximum. Got the DC plumbed in to the main trunk line now. Its had work on your own doing this stuff, but all my mates work full time 5 day weeks so its hard to find some midweek help. Also got started on the line to the SCMS, but angles are all bad. I can only get 15 and 45 degree angles from the local plumbing store, so I am limited to what I can do. 30 degree bend would be nice! All I want now is to get some serious dust collection to the SCMS and bandsaw, that will keep me happy in the short term. The next major step will be the table saw. SCMS aside, all will be running inferior DC untill I can get ports opened up, but at least its a start.

I priced up some 4 core cable for the VFD at masters the other day, but could not find staff to cut it. Given its 40% off trade elec I was surprised that one of the local wholesalers was cheaper than masters firesale! Mind you, full rolls from masters are still WAY cheaper! Good to see that even off the tools now that some of the wholesalers still look after you!

Are the 15 degree angles available in both F-F and F-M configurations? If so then you just nest a 15* F-M into a 15* F-F to give you a neat and tidy 30* F-F overall.

A 15 degree fitting story...
The plumbing supply I went to told me that the 15 degree ones are 3 times the price of other fitting ....why....because they do not sell many????

Sounds like a bit of a stretch.
At my supplier, DWV 15º bends are $18.57, 45º are $11.33 and 90º are $17.08, Stormwater 90º are $10.95

Making a 90º using 6 x 15º gives a nice wide radius if curvature bend but at over $100 is probably not worth it.
The only place I have this on my system is just before the impeller.

BTW watch out for the standard stormwater 90º bends as they are a very tight radius so it really is worth using the larger radius of curvature stormwaters or DWV 90º bends even though they are nearly twice the price.
DWV fittings are also smoother at the joins inside.

I got the same story, but the guys at the plumbing store have been fantastic and are giving me trade pricing. I rocked in there and said my mate the plumber told me to come here to get the best price on 150mm fittings (which was true). Told them what I was doing and they have been bending over backward to help me out. That is Sameos at Virgina if anyone wants to know. I think the 15º bends I picked up for about $12.00 but they also told me they are normally quite expensive because they are usually a special order. I thought they said they normally stock 15º and 45º's but I could be wrong, was possibly 30º and 45º's. FWIW, they are pretty much on par with BobL's online mob over there in Perth, but I don't think they have the same range.


Bob, I have avoided the 90º bends based on advice from somewhere (either from here or Bill Pentz website). Only using 45º's. I picked up some 15º bends today and used 3 to follow the roof angle.


I wired up the CV today and tested it. It scared me (read here https://www.woodworkforums.com/f200/questions-re-clearvue-cyclones-209264/3) but goddam it moves some serious air. I also made the stand for the filters today, and made one for the dust bin also. The drum my father has for me wont need the stand but will require a bit of work to get it plumbed in, so the bunnings dust bin will do the job for now. Today I managed to complete the plumbing to the SCMS minus blast gate which I am still to pick up from Stephen at CV Aus. Next is the bandsaw then a future outlet for the belt/disc sander.

At this stage, I am not sure about where I am going to place the jointer, thicknesser and table saw, so the plumbing for that will be sorted at a later date.. I have a new felder slider on order, so probably wont make any serious decisions till that arrives. For now I am mainly using my little bosch table saw outside to avoid dust issues. I will find a temporary solution for the jointer and planer for now and probably sort out a permanent solution in the new year.

I thought that too but 2 x 45º turns out to be the same a 1 x 90º (see picture below) and Bill Pentz also refers to that in his StaticCalc pressure loss program - what matters is the radius of curvature of the bends.
It's only when 15º bends are used next to each other that an improvement can be observed in the flow.



This a is minor reason why we didn't use the standard impeller elbow duct provided by Cleavue - it's a very tight radius of curvature and it's like adding 7 extra feet of ducting - the main reason was, we were able to make our own 2.5R duct for next to nothing. The disadvantage of a 2.5R elbow is it increases the footprint by about 225 mm in width. It just seems odd to me that ClearVue would go to all the trouble of streamlining everything else but fall down on such a simple thing.

These are the stormwater 90º and 45º elbows
These are 1R bends

This is the DWV 90º, it is a 1.5R bend and will be superior to the 90º or 2 x 45º Stormwater.

Why aren't you using the large radius 150 mm conduit bends?

Clipsal - 247P150 - Conduit Bend, Large Sweep, 90Deg, PVC, 150mm, Electric Orange

They work with white 150 mm pressure pipe and may also be available in white for telecommunication wiring if the orange colour puts you off.
