Somehow I doubt it - there won't be any pneumatic gate operation at least in the first instance.

Does someone have a ready photo of their ClearVue on a stand alone stand.

Some photos here Bob

I unpacked the Mens Shed CVmax a few weeks ago and we are still working on insulating the enclosure.

Meanwhile I am working on transitions.
The first of these is the 90º elbow that comes immediately out from the impeller and connects to the filters or a Muffler.
This elbow can be purchased from Cleavue but it appears to be a sharp 90º elbow (1R i.e. radius of curvature is equal to the width of the opening around which the bend is taking place) so I decided to make a 2R bend. It's actually a 2.5R elbow.

The elbow sides are made from 18 mm MDF using a bandsaw.
Before cutting the MDF two 1.5mm deep , 1/4 circle, grooves are routed into the MDF,
The curved sides that sit in the grooves are made from the sheet metal cover of a clothes drier.
The 3mm thick Al used for the flanges came from the men's shed inexhaustible supplies.
The flanges were cut with a WW BS and the openings routed out with a 1/4" carbide bit on a router table. A quick swipe of candle wax along the top of the cutting track made all the difference between the bit galling on the ally and a clean cut.
Real $ were shelled out for 2 lengths of 1/4" all thread, a packet of dome nuts and a cheap spray can of quick dry enamel (all up about $20).
Even though it is on the non-dusty side of the cyclone I will seal it with some no more gaps before installation



And here it is assembled




Nest transition will be an S shape with a 90º twist in the middle -

I am impressed Bob , but puzzled by your earlier comment regarding gates we do not have any pnuematic gates at Mannum.

Sorry, I don't know why but got you guys confused with Corrimal.

Things are going slowly with the DC setup - too many other jobs on the go.

The management are keen to know how effective the DC enclosure will be at attenuating the sound - in case we need to add more sound insulation so yesterday I had a spare hour so I tested the enclosure for noise attenuation.

I could not use the Dust extractor as it is still not setup because we are still building a few bits and pieces for it.
However, I was able to use a musical instrument amplifier and a noise source (iPad with Faber Acoustical App) to easily generate 95dB at 1m.
The enclosure attenuated the noise by 20 dB, so a 95dB became 75dB (1m away from the closer doors)

I also tried a few specific frequencies, at 1kHz the attenuation was also 20 dB but at 100Hz the attenuation was only 15dB.

So far I am pretty happy with this considering we will be attaching a muffler to the dust extractor and still have to instal seals around the doors.
On the other hand a large vent will be needed on the enclosure to let waste air out so that will set some noise escape.

The critical thing was that the noise be sufficiently attenuated by the tine it reached the nearby (public access) footpath and the nearby senior ciitizens centre.
This was difficult to test because the ambient noise was around 70dB caused mainly wind and human activities.

We started to install the CVMax into the enclosure today.

We are going to use a full size wheelie bin for chip collection so the Cyclone support brackets are much higher than usual .
This makes the lifting of the mounting plate, motor and impeller (~40kg) over 2.5 m onto these brackets rather tricky especially as there is little room up inside the enclosure.

What we did was use a small (400 kg rated) manual forklift/pellet lifter, the top of the tines being covered with a 5mm steel plate.
On top of the steel plate we placed a router table stand like this.

On top of the router table stand is a sheet of ply and then on top of that was a hard plastic step.
On top of the plastic step was a piece of thick plastic and the finally on top of that came the impeller/motor/mounting plate

Sorry it's not a good photo - phone camera and low light.
Instead of the wooden motor mounting plate supplied by ClearVue I made a replacement from some 6mm Al plate.
The wall bracket is made of glad Patio Tube and 6mm Al plate.

We just kept pumping the forklift until the mounting plate went up between the HD Al bracket arms bolted onto the enclosure walls.

Then we rotated the motor mounting 90º and lowered the forklift leaving the motor / impeller / mounting plate sitting nicely on the main Al Bracket.

It was a bit like those photos of someone doing something silly, like a chair on a ladder on a table changing a light bulb - but it worked dead easy.

We have made the muffler and should be hooking things up next week.

That little pallet lifter was a donation and has been a fantastic gizmo. We have used it to load lathes and machinery up to 400 kg on and off trailers - the ability to lift something up to the height of a trailer tray and slide things off the forklift onto the tray works so well.

nice post Bob, I will be doing something similar in 2016 for my dusty. possibly an upgrade to a bigger dusty

We made a small amount of progress on the installation of the Clearvue this morning.

As we were assembling the impeller to Cyclone chamber I could not help but notice the mismatch in the size of the cyclone exit (198mm) and the impeller entrance (229 mm).

More significantly is the fact that the transition is not smooth but a two step transition like this.

I'm not sure if all Clearvues are like this but this must impact on the flow so I am going to insert a radius annulus or ring in that step.

I'm just wondering and if anyone else has noticed this before?

Didn't notice it on my standard Clearview(doesn't mean it wasn't there). I made a silencer similar to Corrimal's so I would be very interested in what you have come up with BobL

Just an update on the cyclone install for the mens shed. I know we are dragging this out way longer than necessary but I'me only getting half a day a week to work on it.

Here's the reverse bell mouth installed on the step between the impeller and cyclone.
Here it is turned up out of MDF on the trusty Woodfast.

And here it is in place showing how it fits.
We did paint it before finally screwing it in place.

So the cyclone is finally installed, now the muffler and the ducting goes next
The muffler is the large blue box that has to be attached to the outlet of the impeller and placed on a stand to get it off the ground so air can escape into the enclosure.
The switches you see are the main isolators for the compressor and the cyclone.
Both machines will be switched on/off inside the shed and are also on a timer that enables power only between 8 and 5pm in case someone leaves the compressor on.

Bob don't discharge the muffler into your enclosure everything will be covered in dust within a week. Come and check out the Bicton Men's Shed's installation on the amount of dust in our enclosure from a small leak in our muffler.
