Clearvue adaptor
I’m helping a mate install a dust collecting system in his shed. I have some expertise in ducting, gates and automation BUT absolutely none on his purchased Clearvue dust extractor! The Clearvue is obviously a fantastic piece of kit and, as the shed is a loooong way away, we have a good scale plan of the proposed duct and gate layout to know what to do there BUT, the Clearvue adaptor to join the duct work to the dust collector has a few surprising ‘issues’ and is more of a puzzle?

It is fabricated from heat formed acrylic. It is sort of round at one end and sort of old fashioned TV shape at the other. It is approximately 220 mm diameter when you squeeze the end to make a circle but, the circle has an overlapped join which makes it very hard to make it a complete circle. Also, the ~220mm diameter doesn’’t match Australian standard stormwater duct ..........

.........which has a 240 mm ID and so most people who use duct tape inner tubes and fencing wire to match the adaptor to the duct work, have to accept a 10mm step in the airflow all around the whole circumference! Having offered to fabricate a new adaptor to fix all of these issues (🤭😳), I went away for a very heavy weekend and after numerous wines I suddenly realised that there was a way to use the Clearvue adaptor mated to a short length of duct which joined the 2 AND provided a tapered rather than stepped change of diameter!! My ‘cunning plan’ required the use of a tapered plastic bucket but I insist that I was not inspired to use a bucket by my excessive drinking!
I luckily found a bucket whose dimensions BUT NOT COLOUR were perfect for a man with a hangover!

..... so, I smothered it in Vaseline, tapped a 150mm long section of 240 mm ID duct over the taper, then followed that with the Clearvue adaptor which was clamped externally to (hopefully) seal the gap between the adaptor circle and bucket....

I then filled the tapered cavity between the duct and the adaptor with epoxy...

...... which I had planned to be white epoxy ........ but at the last minute I COULDN'T FIND THE WHITE PIGMENT!
So, this is the close of play for today. I went up to the house to watch the cricket but that didn’t last long and I am now left wondering IF I can remove the bucket, IF the bucket will leave a smooth taper from 240mm down to an irregular 220mm diameter and IF I have created a smooth circle at the entry to the Clearvue adaptor?

I don't think the plastic used by ClearVue is acrylic but PET, I don't think acrylic would be suitable in that application as it will in time go brittle.
It depends what sort of plastic that bucket is made of, but if it was a cheap one chances are it might spilt.
Buckets made of polypropylene or HDPE like those used as paint tubs are OK.
I have used buckets as adapters eg

In this application the bucket was PP sealed with silicone but after about 5 years started leaking so I replaced the silicone with a sponge rubber.
Since then I have switched it to a BMH and polycarbonate (PC) sheet.
For the mens shed Clearvue I made up a slightly conical adapter from a piece of 0.4mm thick galv. It goes over the ClearVue's 220 mm outlet to a piece of true 9" (228.6") spiral wound ducting. The geometry is dead easy and I just overlapped the sheet by 25 mm and joined it with pop rivets and a smear of silicone as a gasket along the seam. A sheet of PC would work nicely in this situation.

Sorry Bob, I didn’t explain it well enough, the bucket is only a disposable former and has to be removed. I hope it will come out in one piece but happy to cut/split it out if I have to? The plan is that the Clearvue adaptor fits to the mount on to the dust collector and the 150mm section of ‘225 mm stormwater pipe, fits into a ‘225 mm stormwater union’.

Brilliant! In my experience, solutions to significant problems which are revealed under the affluence of incahol are generally expunged by its well known side effect of partial amnesia. Undoubtedly you've discovered the antidote.
On less serious topics, I believe buckets are normally made from PE. Straight PP is too brittle but PP Copolymer is not. Clearvue use PET(G) for their components.

In spite of my anxious night I slept well. The gaudy bucket didn’t survive the process but once it split lengthwise, it simply popped out leaving.....

..... the best result I could have hoped for. IF I had prepared properly and had the white tint to hand, the inner ramp would have been virtually invisible but, as it is, it provides a very smooth transition from 240 diam down to 220 AND has held the Clearvue adaptor entry to a circle with the overlap filled.

You are now the master of epoxy.
Those were the droids I was looking for.

Excellent result there Alan, I think I solved the exhaust adapter issue yesterday as well so full speed ahead.

God, you blokes have too much time on your hands. Clear, black, white, mine are all held together with duct tape and at best a cable tie . I've always got to much woodwork to do to fuss with ducts, get back to work Merrrry Christmas and Happy New year to all.
