Sir George Cayley's Gliding Parachute completed


Here is Sir George’s flying carriage in all its kite-looking beauty.
I followed neither the “flying” replicas nor the modern renditions but the original Cayley’s drawings. In his description he states that wire or rope may be used for the rigging, so I used “rope”, more accordingly to contemporary ballooning and nautical practices. In his drawings the fore mast does not protrude above the sail, and so it was depicted here too.
The step-by-step post explaining the building of the model is here:
The sight of this model is refreshing and helps us understand and appreciate the hard labor, keen minds and ingenuity of the aviation pioneers.

Gwinn Aircar (Scracthbuilt 1/72 model of second plane) completed

The second model –this time of the second plane built- is now completed.
I want to thank Mr. C Psarras and the wof-wof team from Malabamba for their kindness and diligence in providing the decals needed for this project. Without them I could not have finished it.
The first Gwinn Aircar model on this blog is here:
Building process:
Finished model:
Building process of this second model:
Nice references were published in Skyways Magazine, which is an overall excellent publication with lots of useful information:
This second, bronze-colored model was also a demanding endeavor due again to small size, complexity, shape, details, etc. and took -as the first- a long time to build.
The results are nice, though, and almost justify the time, resources and effort invested.
Enjoy!
(you can, you did not have to build it :-)

Scratchbuilt Cayley's Gliding Parachute, 1853

 (The completed model is here:)
http://wingsofintent.blogspot.com/2013/07/sir-george-cayleys-gliding-parachute.html

Since we are already involved with the pioneer period I thought I’ll have a go with a true ancestor of manned flight: Sir George Cayley’s gliding parachute of 1853.
Although usually understood as a pure glider, it seems that Sir George envisioned it more as a way to descend from an air balloon in a controlled and safe fashion.
Do you know who Sir George was? Nope, I am afraid he did not create an app for your smart phone. Say again? Rock star? Hum, perhaps not.
Let’s do this, why don’t you go and research him and his creations? it will be a rewarding experience. Sure, it will take a little time and you will have to abandon the comfort of the couch, even better then.
I'll only say that he was from Yorkshire, that is where my wife comes from (this is another futile attempt on my part to demonstrate to her that modelbuilding is an interesting activity).
Anyway, there is out there a nice model kit created by Aircraft in Miniature Ltd, in its series “Historic Wings”. It is a mainly photoetched kit in 1/72 scale, accompanied by some accessories in white metal and covering material.
Even with that nice little kit available I decided to go some different way and use mainly styrene sheet and rods for its construction, since I usually work with them and am familiar with its characteristics and potential. 
After a brief period gathering the usual amount of confusing and contradicting information -that makes of research the truly entertaining activity it is- I was ready for a version of my own.
The subassemblies: a gondola, the wing structure, the tail and a sort of second, smaller tail used to steer the flying carriage. Other parts like wheels and masts and covering and some rigging are in order too.
Now, whilst every drawing, model and museum reproduction has its masts one leaning forward and the other backwards, the “Historic Wing” model has both leaning backwards. This you may want to correct if you are building that kit.








 Here I demonstrate how to make rings with the magnetic power of your fingers:
Just for the heck of it I grabbed some Milliput and modeled the gryphon head present in some of the old drawings:
The sail is cut:
 The tail feathers are prepared, whilst masts and spars are painted wood color:
 The wheels are now ready to be painted:
The painted frame and the sail which was faintly embossed with a stitching pattern:
 Tail under construction:
 Finished tail and sail dry-fitted to the frame to appreciate the overall translucent effect:
The assembly that constitutes the steering device with its tiller is also finished, the wheels are painted a base color:
 A view if the sub-assemblies so far:
The two masts are anchored on the gondola:
The sail is glued to the frame:
 The tail is then glued too:
 A slot is made at the fuselage bottom as per some Cayley drawings. The idea was to install some kind of breaking mechanism:
"Rib tape" is applied on the extrados and also some "reinforcement" patches, all done in rice paper:
The gondola is given a couple of layers of paint, a darker wash will be later applied:
After the wash:
The wheels are installed:
The gondola is attached to the frame:
Rigging under way:
