Thread: Duct size.

They sure do add up but OTOH how likely is it that you will really need to use it 20 full days a month?

I am hoping that once I am finally set up how I want it, that i might get maybe 20 days a month in the shed and most of my work is timber as opposed to metal work - so lots of dust probably.

I have to make the height adjustable bench first....

The after that, I KEEP on looking at BPs plans for the Cyclone and imagining how I would jig up to make the cylinder, cone and air ramp - all out of sheoak... curved boards with tongues and grooves, with circular sheoke hoops top and bottom of the cylinder and top and bottom of the cone, and then bolt them together thru the timber rings.

I think I could swing it so the inside dimensions match BP's sheet sizes...

Wouldn't be easy or cheap... really it would be a waste of time and $..... BUT it would look "crap hot!"... and for the life of me I just cant get the idea out of my head.

Was thinking if I jigged up for it, that I could turn out components kits flat packed, for others to put their own together... out of any timber really...once mine was done as an example...!

Sheet is undoubtedly the way to do it - which is why I'm keen to have a go out of say 40mm wide 13mm thick boards...around an 18 inch dia circle... maybe I'm just perverse bye nature...

It would take me heaps longer... (routing the air ramp channel in all the individual inner and outer cylinders pieces for e.g.) and tapering all the air ramps pieces so they go round in a descending spiral... and then T & G the air ramp pieces...

No one would ever see it inside the blower section... but what the hey!.
I so far haven't seen anything in the build that isn't "doable" in solid wood.
Bit like building a timber boat... (Cedar Strip Canoe)?

I keep trying hard to talk myself out of this folly.
I was thinking maybe a U tube Vid series in it, or a thread with step by step pics, or a magazine article or something..

If time/cost was an issue there's heaps better, cheaper, ways to build a cyclone...
I'm thinking mine would be "unique" I guess if nothing else.

I know its sheer folly - but I keep finding myself studying BP's plans and figuring how I would complete each step...in solid wood. Missus (SWMTSWTP) keeps hurrying me up when I'm in the shower... turns out I'm thinking thru my cyclone build...

People build cedar strip canoes, so a timber cyclone shouldn't be impossible.
I don't see why after 20 years wood work skills I should start learning sheet metal trade to make a simple cyclone...
I'm thinking a round main 8 inch ducting trunk line - in similar timber strip sections, (or banded), might also be "novel"...
It would make for an "interesting" shed environment to visit and work in.

If a bloke was smart and computer tech savy, (which I am decidedly NOT) he would do it all first on CAD... maybe even CNC plans for nesting and cutting all the individual components into timber sheet material of any type (16 mm Mel HMR?) - depending on your budget.

Maybe a sheet or two of 1200 x 2400 16mm white Mel HMR @$35 from Bunnings and plug in the CNC cloud file and out pops all the components all cut & machined, ready to go together as a kit.

I reckon (Maybe) $200 materials costs all up... tops.

How hard could it be?

Maybe I should be talking with someone in the CNC forum?

Heck the air ramp COULD be cut from white masonite cabinet backing (or 3 ply if your flush with cash) and fed into the routed ramp dado slots if time and $ are an issue.

I can think of a few different ways to do this.... some easier or harder than others.

I hate it when my brain gets like this... it just won't let go sometimes!.
