Guessing again on Florian's mystery puzzle part with the following guess:
Is this guess correct or not?: The part joins two queenposts to keel and allows a direct hang-pilot connection

I am being blocked from posting the tech discovered by JoeF.
http://www.northwing.com/wing-junctions ... ossbar.htm
this shows why telescopic tubes are impossible.
a spar pin remedis this situation but I am blocked.
we found the glider used in moon raker made by UK birdman

the spar pin is a game changer thak you JoeF.

I've reached a decision to invest soon for a mockup of a Wing4 for TPHG 4    rather than the border deal of "5" where "5 ft" is the border upper limit of the topic of this discussion thread. 

 A comparison has been occurring in my development notes between the 5 deal and the 4 deal and the 3 deal and the 1 meter deal. Here are some of the 4 deal potential asset spaces:
4+4+4+4=16    Couplers.
4-0.5+4-0.5+4-0.5+4=16-1.5=14.5   overlap telescopy
4+4+4=12   Couplers without extension
4+0.5+4+0.5+4=12+1=13 with couplers involving interior stops giving extensions. If a coupler adds 1, then: 14 here.
Possible more COTS-supply choices with 4 rather than 5.
Easier DIY CF tube making at 4 rather than 5. 
Buckling-resistant compound beams using 4 with 4, either telescopy overlap or coupler. Consider KP, QPs, struts, ribs, ...
---- 4-2+4=6
---- 4-3+4=5
---- 4-1+4=7
4 for various uses or 3 or 2 or 1 ... battens, sprogs, stiffeners, controls, axles, Invites an option for ribbing that may moot stuffers and pressers for "airfoiling" the wing.
Invites a more polite length for busing, storage, trunking, carting, training, hiking. 
Still at about two cubic feet for tote volume.    
Part exchanges might then be less expensive
Dividing matters into two packs for frame beam parts seems easier to option when in the 4 area, if needed.

ChatGPT gave me a "sure"-kind of response on the "airfoiling" word:

Yes, "airfoiling" could be used in the context of aviation to describe the process of forming or shaping airfoils in a wing. While it's not a standard term in the industry, it logically conveys the action of creating or refining the aerodynamic shape of a wing or other surface to optimize its performance. In aviation and aerodynamics, the term "airfoil" refers to the shape of the wing or blade (of a propeller, rotor, or turbine) that generates lift or thrust when moved through air, so "airfoiling" would be a reasonable way to describe the crafting or modification of these shapes

My usage of queen post or queenpost may not be common in hang gliding.

https://en.wikipedia.org/wiki/King_post
Spelling variant: kingpost, king post
Spelling variant: queen post, queenpost
Kingpost may be at top of a wing used for stay-line anchoring to stabilize geometry of glider when wing is not cantilevered.
Queenposts are downtubes of TCF (triangle control frame). Two of them are common.


Flying rigging may use queenposts to stabilize wing geometry.
Landing or neg-G lines may use kingpost to stabilize wing geometry.
Use of "queenpost" in different fields of application may get confusing. I am using the queenpost term for the two compression members that are below the wing and thus below the kingpost. In some field of appications, queen posts may be tension members but still be posts. In hang gliders queenpost is not as common as "down tubes" of control frame. Queen post is not common in hang gliding, but I have chosen to use the term for the downtubes of the TCF, to have king and queen doing stabilizing and rigging matters!

Thank's for your definition of the "Kingdom Posts"

But regarding this definition, your guess is not correct in this case.

Try again

Florian's puzzle piece
He confirmed that my three guesses were not on target. Not spar deflexing bracket, not nose plate, not bracket for downtubes (queen posts) to keel. Others have yet to post their guesses for the puzzle part of his TPHG 4.6 that is underway being built presently. See the part in a post not too far back in this discussion topic. He teases to have us draw the third dimension of the flat-imaged part.
????? TIME FOR ANOTHER GUESS ... by anyone!

My fourth guess: The part will be bonded to the end of many spar-segment tubes; then two such items will be bolted together to act then as a spar-segment coupler. Such is my fourth guess. what, Reader, is your guess?
My fifth guess: The part will be the base of tote bag; mount casters; place packed wing atop the part. Is that it?

[Bob Kuczewski]

what, Reader, is your guess?

My first guess was a nose plate, but that's been guessed by Joe and rejected. My second guess would be part of a "deflexor system" (as Joe also guessed), but that's also been rejected.

Florian suggested imagining the third dimension. Hmmm...

I think we could use another hint.   

[JoeF]

Another guess: I think the Florian part folds and becomes a bracket for the lower terminus of the downtubes (queen posts) of the TCF (triangle control frame).
Is this correct or not???

[Semper Fidelis]

Please read carfuly my previous answer to Joe

Not a plate
Not shur to be lighter
But, even if it might look like a "heavy A-Frame"... the nose (2d view)

Yes it is the nose but not a plate !

[Semper Fidelis]

I think we could use another hint.

Ok, I'm not going to give you the right answer just like that.

Just read carefuly and take time to think, like a SUDUKU game.

You already know that this KEY PART is the NOSE PART... but not a plate, nor a bended sheet of steel.
You see that it is a shadow of the piece, so you only have two dimensions and I'm asking you to discover by your cleaver imagination the third dimention of this element.

The shape of it should help your imagination too. For instance, if you see a hole in a piece, probably thant something will go into this hole, but what and why, those are the deep questions ! This piece will be machined soon, I do hope you find the answers (only one answer but composed of WHAT and WHY).

Please, take the time to draw something so explain your guess.

9 pm, good afternoon to you
