What have I done here?

I think what amazes me is the amount of thought and research that went into whether the lines should have hard edges or not in times of limited technology!

No wind tunnels, no liquid flow dynamics, or any of the other technologies sat at the back of a Formula One team garage that costs tens of millions to return a 0.004 second improvement in lap times!

They knew all about aerodynamics though. A lot of the data was gathered by experiment. They had wind tunnels too. The Germans had one big enough for a full sized fighter. Most, as today, were big enough for models.



This is the Hermann Goering wind tunnel at the 'Luftfahrtforschungsanstalt' (aviation research institute) Braunschweig in Germany (obviously).

You might be able to make out the typically Nazi slogan on the wall in the background:

"Das deutsche Volk wird sich

durch die Eroberung der Luft

seinem ihm gebührenden Platz

in der Welt erzwingen."

This translates roughly as "The German people will by the conquest of air seize its rightful place in the world."

A couple of interesting articles.

A knew of a wind tunnel at the NPL (National Physical Laboratories) as the year before leaving school I had decided, on the recommendation of my Church Organ Tutor who was a scientist at the NPL, to study Metallurgy and the Fatigue of Metals. Decided in the end to join the Fatigue of Architectural Training. I have always wondered if I would have become involved on the Comet metal fatigue problem.

How did we get from an airbrush problem to a wind tunnel although I suppose it is all pushing air around.

Getting even further off topic, there is a BIOS report (British Intelligence Objectives Sub-Committee) on this facility. It covered four square miles and the British, or more accurately the Canadians who wrote the report, were mightily impressed with it. I have a copy of the report, but for anyone else interested it is No. 160 and comprises 44 pages of data about the site, the various wind tunnels, including a supersonic wind tunnel capable of achieving Mach 1.75 and a water tunnel.

Report No.119 covers the other major aviation research institute the Deutsche Versuchsanstalt fur Luftfahrt (D.V.L.) It covers the different fuels and a bit of engine testing.

Sorry to throw a curve ball but the OP of the "freehand" comment, was I think possibly referring to the actual shape of the line rather than the demarcation between the colours.

The flow of the line being soft curves rather than jagged.

Still the resulting posts where very informative.

Hahaha!! OK, I see your point now! You mean a more flowing camo pattern like in the real thing:

And not the randomness of mine! Come to think of it I seem to have replicated something more akin to tank camo, I see your point!

I also notice the above picture of a Hurricane in the RAF museum quite clearly isn't a hard edge camo either!

Good point, and he'd be absolutely right too. I love the S shaped curve on the starboard side, under the cockpit of a Spitfire like Johnson's here.

Is that the real one, or the one you built last year Steve. ;)

Mike: Steve is a gold mine of info (thank God). He has helped me out many a time.

Yes there is Steve but for the life of me I can not remember what it is. :eek::oops::rolleyes:o_O:D

That is very funny and I had a good laugh. Cannot tell Pauline my wife tho. as she will have a better come back. O yes she will. Plus she will fall about laughing.

You're not wrong John :smiling3:

Here's one of the original photos I took of the model when I was really trying to match it to the famous photograph from Spitfire:The Canadians.



I reckon I got the prop a bit closer then !

Now whilst you've all been researching, I thought I'd get back to my Hurricane which is now fully painted, it's just a case of putting the decals and fiddly bits on. This new tooling lark is an absolute dream, right up until I accidentally cut a fiddly bit when taking it off the sprue, I didn't think it an issue, but turns out it's structural! Take a look below:

On the left hand landing gear, we have a horizontal stick that goes under the sticking out thing right into the wheel well where it is glued.

On the right hand gear, that bit was accidentally cut taking it off the sprue and what's left doesn't reach the sticking out thing and it's particularly flimsy because of the lack of support. I fear when the glue's dried and I put the wheel on it's just going to collapse under the weight of the plane!

In other news, I had to respray this aluminium colour in an area here after the masking tape was removed, with this extremely close-up photo, you cannot tell where it was, so thanks for the airbrush advice! Worked a treat :smiling3:

Looking at it in a photo it looks OK Mike. Not much weight and providing you are gentle with it it should be OK.

But if you are concerned can you not make up from the sprue a piece to splice in where you have occidentally chopped it off. can you reuse the bit you chopped off ?

The landing gear is always fragile I have found. I have in the past used Super Glue the gel type to coat pieces which just gives an added strength. Also try not to fit the landing gear until the last moment or pad out with foam in order that the landing gear does not come in contact with the work top.
