Dust Extractor Availability
Now the Clearvue has bit the dust in this country buying a DE of that capability is nearly impossible and modifying a marginal one to be a bit less marginal is a non starter when talking about bigger installations. I shopped around on Friday and found one on the East coast and no one knows when more will be available. If you have a Clearvue Max and want to make a few dollars now is the time to sell it, give me a call and I can hook you up with a buyer.

If you want one it is either import it (transport costs prohibitive) or build it here. The impeller is the biggest hurdle and always has been though I did have one made locally a few months ago and then we had to make the taper lock as that was unobtanium in Oz at the time. I find it interesting that the Taiwanese sources are also drying up also for similar reasons, supplier costs and transport have risen hugely to the point it is now viable to make cyclones here.

So I should start tooling up to make them? IF there is enough demand, I will look into the cost of it.
I have the technology to make the impellor, just don't have any way of balancing it. I'll have to take a look into it. I also have mate who runs a lot of CNC mills and lathes, so turning out taper locks would not be a problem.

If you see enough volume in sales why not. The balance would only have to be static as it is a fairly low speed device when it is all said and done. In the ten years of sales there have been perhaps a thousand units sold and about 20 of those were to one company. I sent 4 to Mongolia drop shipped out of the US for coal dust sampling for that same company.

balancing is relatively easy,you just need to make up a dummy shaft
This may help Balancing Know-How: Understanding Unbalance - YouTube
I learned a lot here Centrifugal Blower impeller(Blower Wheel) Fabrication All Stainless Steel - YouTube
I bought a weldable hub from a local supplier, with a matching taperlock, for about $35.
I have not actually fabricated the impeller yet, I have just completed the plasma cutting table and bought the steel, but things keep on coming up to rob me of time... (like this London Plane which I now have to get across town & mill this week)
Eventually I'll get around to bending the fins & welding them to the back plate

Whatever you do when making the impeller don't undersize the steel thickness.
What folks don't realize is that even at 2850rpm DC impellers "flare" they flex at the hub which limits the clearance possible between the impeller's OD and the internal impeller housing wall.
An example of this is here
Boring out an impeller collar - Page 2
The flexing is possibly why some impellers still use rivets instead of welding. Any welding on these should be stress relieved but I'm pretty certain you would already know that.

Sounds like there is definitely an opportunity for an Aussie outfit if they could produce units that function well and end up priced some where between the Laguna units and the Felder RL/Alko machines.

Reviving this old post from 2022.
Has there been any further attempts at making the impellers locally?
If the impeller is the main stumbling block at making a BP cyclone, what would it roughly cost to have one manufactured here in Oz by a machine shop?
Desperately seeking a better dust extraction option than my 1HP, and my workshop was built/designed in such a way to house a BP cyclone, this was before the local mob closed down.
