There's what, 4 posts asking after me in a year? I seem to be as popular as a man at a Feminist Convention wearing a strap on dildo.   But I am highly unimpressed with mostly Murdoch's lies

Ah, there is the problem. Pushups. I never do them. Better to stress your heart with a good Cabernet Sauvignon.   Good to hear from you Bex.

The term Authoritarian is defined by the Economic Intelligence unit a division of the Economist Group based in the UK and is when political pluralism is non existent and includes monarchys and dictato

Yeah, be ready about Wednesday week Mate ...

That's what sets Bex apart from most of us watching from the sidelines. You have to be an determined optimist to tackle a project like this. It's no small task.

FT, I really like a bit of immigration. My favourite bakers shop and restaurants are only 2 examples.

 

But right now we have insane levels, 700 a day or so, which is far more than is good for the country except if you own a bunch of investment properties like Xenephon does.

 

And even before Bex, I was thinking I had been lied to about China. I had been given the impression that it was a nightmare country for ordinary people, and especially for disabled people.

 

Then I saw their disabled Olympians, who had clearly been in the sport/training business long before the Chinese Olympic bid could have been thought of.

 

Bex gave me further evidence that Australia in some ways is more corrupt than China, something which is obvious to me now but I had not realised and which will never be understood by the average voter.

So need to make a start in the wing ribs and skins department ..

 

First I need some rib patterns, draw the wing in 3D, slice accordingly, check fitment and then to 2D for detailed design, and later for cnc cutting out.

I personally find this the most addictive thread on these forums and get quite excited watching how it's all coming together piece by piece.

 

There's so much innovation, apart from modern day technologies assisting this build, it's great to follow.

 

Many would also be a bit envious of the building space available, that appears in many of the photo's.

 

Although i'm not building, I still learn a lot.

 

Can't wait to see what comes next.

 

Great job mate!

Need to get my son to order more aviators to replace the ones he flogged while borrowing my car.

 

Last delivery was super-quick.

 

More should use the service. It's great!

Just lining the rear stuff up, taking measurements, shifting stuff around etc.

Getting into the new tapered wings as well, the tapered spar parts are ready for basic assembly ..

How heavy is this thing??

Looking at it I imagine it's about 10 tons, not much info on the net about gantry cranes to confirm it though, sorry.

What a great day.

 

I had a go at a new rib system today which is stupidly simple for anyone to do, more accurate, stronger and cheaper.

 

Easier for me to produce because it's modular for any rib size or shape which particularly makes a tapered wing easy to produce and to build as seen by the 2 sizes I tested today.

 

Over the last couple of months I have been testing different rib configurations and this is just awesome!

Well looking at it, you might even think I was building a plane or something ...

Great Shot .Love the rib flanges, they could be 2 meters long and just snipped to length per rib....................If it were a model aeroplane it would have a small "D" box or tube to help hold the leading edge radius plus stiffness and straightness ..........................................Actually that's not entirely true, The ribs would have been wood the covering, paper and the "d" box would be from leading edge to spar...But hey! I'm not complaining , I'm with you, all the way....

That's a very neat way of doing it Bex, it would make flatpacking of a kit a lot more efficient. I am surprised that more mobs don't do it that way:spot on:

Eggszackerlee.

 

The strips were 1 meter and I just snipped them to length for both the large and small rib.

Love the simplicity of the flange riveted to the spar but question how well that will work on tapered wings.

 

The traditional flange bent over or tangs bent over allows flex in the radius of the rib to allow for the fact there is a different rib size from rib plate to rib rivet line.

 

With light weight skins I'd be worried that the extreme stiffness at the rib face may cause visual lines in the skin along that line as the rivets pull the skin down to the rib

 

Will be great for straight wings and tail group but I'd test on taper panel across a test section of wing over a few ribs to see how it goes.

 

Cheers.

... and is why I had 3 separate strips bent at 90, 92 and 94 degrees yesterday to test, with aluminium's inherent flexibility, it is manipulable.

 

Valid technical points are always welcome, thanks.

This is interesting, I was sitting at the computer tonight and had a thought, drew it up, will laser it tomorrow morning and see how it turns out ....

So, I thought I would whip up an experimental fold up "Insta-Rib!" (with new chicken curry flavor!) rib which would be assembled at home in a minute, I won't use it, but doing stuff like this gains valuable information about design and processes for other future work, can never have too many ideas!

In the meantime, did some real ribs today, one wing's worth in fact, only took about 3 hours ..

 

I can not describe how fantastically easy and satisfying it is to make these ribs, I think I have a new motto: "Making You The Expert!".

Hi Bex,

 

It looks like you now have the task of bending all the flanges on each rib to attach them to the spar (unless those holes at the spar end of the ribs are to attach them to a spar mounted flange?). If you do not bend them all to exactly the same angle, there will be a discrepancy with their alignment at the leading edge. You probably already have an accurate solution to that potential issue.

 

If not, a potential solution could be to have a separate rib and flange with each flange being bent to 90 degrees and pre-drilled only on the rib face but not on the spar face. The spar face could be back-drilled through the spar mounting holes after clamping the flange to the spar in its required location.

 

Each rib could have a small notch cnc'd into its leading edge which using a taut fishing line or similar could be used to align all the leading edges of the ribs, to then allow the rib to be back-drilled from the pre-drilled spar flange, thereby keeping all ribs in alignment. The ribs could be clamped to the flanges while alignment is carried out and then back-drilled through the pre-drilled flange holes.

 

Just a thought for you but I have a sneaking suspicion that you probably already have this potential (minor) issue resolved.

 

Keep up the great work!! Everyone is finding your journey fascinating and we admire your ingenuity.
