I/32nd I.D Vacform RAAF Canberra B.20

Recommended Posts

Canopy and Framework  .... Takin' Shape :

 

I decided to use the spare 'Round' new canopy for final fitment as well as using it , for the cutting template for the final assembly 'Flat' canopy later...

This would be the way to go when choosing either of the rounded or flat  versions and to use the other canopy on the vac-sheet for the cutting template... as you only get one go at the final canopy!

Now a look at the progress of the canopy and framework so far.....

... Now the clear Bubble top inserted in frame-part ... Hmm... snug fit! B)

The overall look?....She's sitting and looking nice! (at least to me!) 

.. as mentioned earlier in thread , the aim is to get close to the  finished part - @ 75% complete .... which I think I'm getting close. 

Once I'm satisfied that I'm close enough...  the next step is copying the framework in resin and working the resin copy further - detailing / massaging - wise...

I will need to detail underneath frame as well in coming threads... 

 

Now for a quick look of the part in place for over-all effect....

Yep . It's taking shape alright! ^_^

Great effort - but I have to admit I think the shape of the canopy is totally off. The kit part is way too bubble shaped, causing its front and rear being way too steep. The canopy appears way more flat on the photo of the real a/c in the background. Your frame also needs some minor modifications compared with the photo. As it is now, your canopy and frame look like they are put on top of the fuselage whilst they smoothly grow out of the fuselage on the real aircraft. No offense intended, but you are doing such an excellent job - it would be a shame to spoil the overall result with a strange looking canopy...

Thanks Starfighter, constructive comments - they are always welcomed!

Yes you're right in most respects... but as i said in the thread... It's taking shape, but it's no-way near the point it needs to be... the target is 75% finished of a canopy that at the end of the process...(copying in resin and working more on it) will then be at it's  100% 'sweet spot' perfect finished... I think I'm at 50% right now... I know there's further work to do on it - to get it at that 75% preparation target. I have a few more photos coming to show the how complex this canopy and how interconnected all the elements, in this canopy area are. (Stay tuned) 

There's still a way to go till I think I'm ready to copy the framework and then work it further to the finished product. 

Yes your right , It's sitting higher and appears to be so, because the bottom of the framework is thicker then it needs to be... ( and the blue clear protective liner perhaps makes it look bigger then it is)  also the back of the canopy ( extension collar ? or angled piece)  needs to be trimmed further towards the canopy. ( too long) and less angled or 'flatter' as you say  -  which I've since done. 

I wasn't focused on the thickness of the bottom framework at the time but more on getting the clear canopy to properly sit in the framework in the first place ( a challenge in itself).

Now that i have accomplished this ( to a major degree) I will focus more on thinning the bottom framework area,  as  I've  mentioned... and the inner parts of the framework as well ( coming threads).

I can easily miss stuff and extra sets of eyes and comments here, are very welcome.

Canopy - Continued 

 

Now that the Canopy's outside 'basic' shape is established .. my focus is now to the inside of canopy...

I now make a  mounting - ring that inserts into the top of the fuselage and locks itself in - for want of a better description..

I'll let the photos tell the rest of the story.....

Once i had the mounting ring made... I realised the back - inside area of canopy was raised and the tubular vent system went up with it..

This effects the clear window shown as red arrow... (above)

... Here's a better view of back of canopy area...

t0wvw0P.png?1

 

Now for the tubular vents that goes right around the edging of the canopy ...

( to strengthen the canopy frame and to  stop the canopy misting up - I should think) 

Its rather a very bendy and twisty affair  - as shown in photo below...

Because of the roller coaster tubular vent design ... it's makes it very hard to make unless you make a jig or something... so I took the next option of making it in sections and joining them up later...

....All to do now is simply clean up the weld points 

 

Pc14jp4.png?1

 

 

Now test for fit and appearance ...

The canopy sits and fits well.. and thats one battle - won for now!

Cockpit / Fuselage:

 

Time to check for Canopy fitment  and to really show you how bloody complex this cockpit area really is!

The photos speak for themselves...

25XZQQc.jpg?1

 

Now that I've got the major mounting points of most of the parts established .. I can now continue with the wall - liner

 

Here's an interesting comparison between my efforts so far and a 1/48th example of same area..

The padded - wall section comes out as one piece clam-shell design and will be copied in resin at a later stage ( when i got all the cockpit components done)

 

So far - soo Good!

Very taxing work, Phil - but also very impressive!

Thanks Kev,

I hope I've conveyed here, how complex this cockpit really is... Taxing?  Yes very! ... at times, it does push me to my limits - I feel.

It's that 'Love-Hate' feeling we get with modelling as we all experience at times.

Thanks for the comments Guys, really appreciate them!

 

Instrument Panel  

The Pilots Instrument panel ( and navigators too for that matter) are different between all the marks of the Canberra in set up and general 'look'.

Since mine is the RAAF version , I am concentrating on that... but cannot do a 'Generic version' to cover all the marks.

I try to cover all bases but unfortunately, this is a one choice affair for me  regarding this part. Perhaps it's just a simple case of altering the resin panel copies for your own version.( or make a completely new one) .

Here is a study of the Pilots Instrument panel... ( this is the British version - I believe) 

5q4oh0n.jpg

 

You will notice the panel on the far-right is angled back and in two extra smaller sections

Here is a photo of this area in question.... 

 

OdCjKHt.jpg

 

You can clearly see the two angled panels on the right... ( marked red and yellow) 

The B-20 RAAF version has only one angled panel on the right - half side... as shown in next photo.....

 

YhPPPK0.png?1

 

 

Interestingly,  Some Canberra models aren't completely correct in their renditions in this area... ( as per 1/48th model depiction below)

 

 

C1Iy3Xb.jpg?1

 

 

The photo-etched flat panel (above) would be designed for the 2-seater trainer version I should think....

 

 

5W5D3MA.jpg?1

 

 

Maybe the angled panel ( above) is a little too angled? ( depends on what mark or version this is ) 

 

 

 

HEduYhD.png?1

 

now you can see what I mean... also the instrument clusters are different too... 

now to make the Pilots Instrument Panel ( RAAF version) ...

 

CUJtF0M.jpg?1

 

dWLiI2C.jpg?1

 

The cover plates are an entrance tunnel  for the navigator ( and to stop bumping sensitive instrument switches and snagging on sharp edges) 

 

9gpAGyH.png?1

 

ua38uKZ.png?1

 

730cMGB.png?1

 

Basic shapes - Yes, but they must all fit together with other parts in the cockpit - before I detail.....

Cockpit : ( Continued) 

 

Pushing ahead to get the main components made - though in basic form...for the moment

Next , is the Navigator Electrical Control Tower ( highlighted in grey below) 

 

mqqNWH8.jpg

 

Now a study in the Control Tower... The first photo is a British version with an extra component/fitting  on top

 

YCiXr9i.png?1

 

zfgV8RB.png?1

 

UqxJzL3.jpg?2

 

Which version of the Navigators work facia on the Electrical Control Tower I will make,  is undecided right now....

Though, with this information - I made a basic shaped box, which I think will be connected to the Pilots back-partition when the part is finished and ready for molding.

 

sG8R65D.png?1

 

 

Next is Pilots Instrument panel and Electrical Control Tower in place....

 

Xc38GBC.png?1

 

 

You will notice I made additional  'L-shaped'  Pilots flooring ( a separate piece ) which will be detailed on top and sides with possibly the rudder pedals incorporated ( yet to be decided) .....

 

 

WMDe8Ax.png?1

 

Everything 'slides in' as it suppose to... and the basic component shapes are there...

This process is almost like a sculptor chipping away at a block of Marble, until the shapes slowly emerge... and then once that is established, the finer detail is massaged out. (Well this is my approach - anyways :whistle: )

Next... we move onto the Navigators work area....

Navigators work station:

 

A study of Navigators work console/ bench / instruments.....DHUxOfH.jpg

 

Here's a Navigators instrument panel being restored in the workshop.... ( no not mine)

 

gCsYtxE.jpg?1

 

55L34Yf.png?1

 

You will notice that the instrument cluster/ layouts on the two versions shown above and even the workshop manual illustration (top) are very different!

The Canberra B-20 was in Australian service between 1954 and 1982 and there was constant upgrades of equipment and technologies,over the years.. (as most countries)

So! which one to do ?... I Dunno!:shrug:   ( See! I don't have all the answers!)

Lets start with basic construction and hopefully the answer will emerge itself in time...

 

7FPhYFD.png?1

 

XKkMHC0.png?1

 

As I detail this area later - some decision will be made on the navigators layout...
