Spit props.
It could also be down to availability of parts.It,s not like you can drop down to the local shop to pickup a spare prop hub these days.Blades can be remade,bearings replaced but crack a hub and it,s fun time….:diablo:
Also removing radio sets,IFF equipment would upset the COG to a degree I would think.Remember new sets are a lot lighter and compact than an original.An extra couple of weights in the back…..
Sakai 21…I think
Plus they had found a way of being able to cruise the aircraft at a very fuel effecient speed.Think it was high boost and low revolutions(rpm) but this is based on memory.It gave the allies a huge shock finding bombers being escorted by fighters hundreds of miles outside of known range.
Have heard a story,can,t comfirm it did or didn,t happen but a Japanese plane took off from East Timor,flew to Darwin,across to Sydney,up to Brisbane and back home without being intercepted sometime in 1943.One time being passed by Boomerangs without being touched…Anyone know the story???There is a photo of the Sydney Harbour Bridge taken from the air with a Hinaramu on the wing…apparently…..
Ahhh can see it now….
A dreary morning in England…June 1940….
“JENKINS!!!!!!”…
-“Yes sah!!!!”…
-“Where the Bleedin hell is my good Dinner Jacket!!!??”
-“It was hanging up to air this morning sah!!”
-“Well it,s not there now is it!!!”
-“Errr no sah,will kip around and see if anyone has seen it….”
-“Oh and one more think Jenkins….When did the order come down from Hq to paint the Hurricanes in new Cammo?”
-“Sah?????”
-“Yes that Hurri over there,G for George.The one with the black and white dots all over it……”
-“Errr dunno sah,she was up for an early morning hop.Will talk to the ground crew about it…”
-“Good lad and be quick about it….I have a dinner reservation with the Wingies family…”
😮
Times that by three for Aussie dollars….
Aaaawwwww stuff it…I like a challenge so I think I,ll make my own…:D
There,s demolishing and there,s demolishing….
Would it be prudent to allow the Hanger to be unerected properly than by a large bulldozer?That way it could be reused at another site to help protect the heritage of it.
Ahhh but Mr Sherlock……
The welding of Chromeolly is doable.Firstly the item must be heated before and after welding to neautralise the stresses involved.How do I know??Using a two foot long heating torch to preheat fabricated beams in the engineering industry.All the more pleasant by doing it in a welding jacket in the middle of an Aussie summer.Then welding it with flux cored Mig wire then reheating.And all you used to guage the temp were welding crayons that turned colour when the correct temp was reached.:)
To keep the planes in the air the ground crew would have to accomplish all sorts of miracles with whatever was available.Bully beef tins,fence wire,bits of trees…..;)
Maybeeeeeee!!!
They were part of an early PR Spit.A MkI or II airframe converted.???????:confused:
Doh!!!
Forgot about Pukkas panel.Oh well I found this one.Might be Ok…

Will still keep an eye out…;)
Have you….
Checked out the modelling or Flight sim fraternities?The new whizz bang computer generated models are pretty bang on and the modellers are pretty vicious when it comes down to aircraft details…. 😀
Hmmm interesting….
I haven,t got the holey Spitfire bible on me but I thought the drop tanks didn,t arrive till the MkV Spits.That would have it as a 349 number.I noted this as that,s the Mk number where Frame 9 was modified to accept the drop tank mechanism.Check drawing 34927-5-c.Just theorising though….Someone with more knowledge than me can correct me….;)
Missed a bit..Yeah I shoulda edited…
With Parametric we did up a Spitfire rudder pedal in 3D.Then we put virtual stresses on it and found that it would take 50 pounds of pressure on the top bar before it broke off at the pedastal.Material was 6061 aircraft grade Aluminium…. Try doing that with a real one.:diablo:
Swingin the thread….
Nearly derailed…..:D
I have never tried Catia but it is one of the worlds leading Programs in Engineering.If you want to go Inventor I would learn straight 2D AutoCad first to get to grips with the functions and command lines.Nothing beats Parametric though….:p We have the same problem with Experimentals as well.They can do just about anything they want but build a proven design that has been reengineered with new Technolagies and materials then it,s dramas,dramas,dramas.”It must be a bad design as they only built 22,000 Spitfires…”:diablo: Isn,t the saying goes the most dangerous men in the world are dreamers!!!!!
If I was emporer of Earth I would network all the Mozzie projects together.Everyone helping each other out…:D That way everyone wins….
Aircraft Grade Aluminium Alloys….
Haven,t got much into the theory of casting but from my holed memory some grades of Aircraft ally contain Silicon as an element…Instead of trawling through my old apprenticeship books found this site…http://www.luskmetals.com/basic_alloy.html
I agree
Some of the best work I,ve ever seen…Very enthralling and motivational…Keep up the great work guys….:D
Castings….
I agree this is one area we thought we would have troubles with.The Spit also contains quite a few of them.We are looking hard at a small CNC router to machine up “masters” for molds and such and a small foundry crucible and furnace to produce small parts.I,ve heard of guys saving their small offcuts from the guillotine,organising them into piles then melting them down to reuse in castings.Justa thought….:cool:
