These guys seem to have the technique!

That's quite a large radius of curvature they are bending. In a shed one typically needs to go to less than half or preferably 1/4 of that. When this is done the pipe kinks unless it has a former inside it.

Fair enough.
I could imaging that you find something to work for small diameter PVC but it would be trickier for larger diameters. Have to think about that.
Has anyone spoken to these guys?

They say they do up to a diameter of 225mm.

I priced this electrical conduit bends up about 2 years ago and they were all pretty similar i.e. $$$$$$$$ - Ka CHING
They are very thick - much thicker than is needed for a DC system - and this is what makes them expensive as the price is based on the price of oil.

Look here - ELECTRICAL CONDUIT, FITTINGS - ELECTRICAL FITTINGS PVC - Perth Irrigation - Retic Fittings , Plumbing Fittings, Reticulation Supplies, Western Australia
A 100 mm large radius bend costs about $45 whereas 6 x 15º 100 mm bends cost about $20 (not from bunnings)
The price gets crazier as you go up in diameter.

A couple of months ago this was in the skip where I used to work. 12" welded ducting - it would cost more than a grand to get that made.

On the weekend I picked up the DC3, connector starter kit from Carbatec with a few other bits and a truck load of 100mm connectors and pipe from Bunnings.

After many hours of trying to solve the puzzle of what connectors to use where and limiting the use of the corrugated my man cave is now fully ducted.

And I am stoked. The new unit works amazingly. I have connections to my table saw, my work bench (most for the thicknesser), the lanisher and my drop saw. Not a sceric of visible dust when using the Thicknesser or Lanisher. The unit is also a lot quieter then the Kincrome Shop Vac. Fantastic outcome

Thanks again for everyone's help

Glad it's worked out for you.

Report back in a months time and let us know how the fine dust situation is - that will tell us if it is working for that.
