Just look at those clamps! What with @Colin W use of a beltsander, this year's KUTA should have been sponsored by Screwfix!

Full of admiration for your work, I'd be so frustrated if having braced everything I then had to take some of it out again.

I'd say this build alone justifies a KUTA extension, which I think would be a first!

At the rate this is progressing, it would need to be one heck of an extension! 😂

 

It might, however, feature again in the next KUTA!

Just found this thread Matt.

 

What a giant this one is, 1/144 scale 747's are big enough for me, although I must confess one of the few purchases I made at Telford last November, was a 1/72 conversion kit for a Boeing RC-135V/W Rivet Joint, which will require an appropriate 1/72 C-135.

I keep relatively quiet about the 1/32 Lancaster that came into my possession last September 🫢

 

Big planes are in my future somewhere, so I'd better keep an eye on this one! 

 

Good luck!

Hi Matt, should you be interested in adding some nice detail to your 747 project:

Titan model Kits has an 'extended flaps set' in development :analintruder::

Hi Terry, welcome along! She's certainly a big beast...! 😁

 

1/72 big jets are very impressive once built but they have their own set of challenges along the way. The only reason for having detachable wings on this one was to make handling the model more practical, otherwise I would be constantly banging its extremities!

 

I would keep quiet about the 1/32 Lanc as well, but I'm sure somebody at home will notice it coming together! It should be a stunning model when it's done.👍

 

Work will continue sporadically on this one and I suspect it will make another reappearance in the next KUTA GB! Having said that, I'm very happy with the progress made over past few months, following decades of neglect - it might not look like much but some major hurdles have been overcome.👍

 

@Wolfhound32  Those Titan sets look the business. Unfortunately I don't think this particular model will ever be good enough to justify those add ons... Hopefully I'll build another large 747 at some point in the future and will certainly keep Titan in mind for any AM goodies! Extended flaps with that degree of detail will be a great addition.👍

 

A quick update on this build, which has been plodding away in the background more than the limited posts on BM would suggest...!

 

My first job is updating the title of the thread for the third(?!) time - this model is now destined to be a -300 again, having sold the -400 conversion kit I bought due to the belief that I could never make that conversion look right!

 

Other jobs have included cannibalising the huge stand that came with my 1/72 Concorde. That particular model will be stood on its wheels, so the stand is surplus to requirements and is ideal for this model:

 

s0.jpg

 

A suitable internal recessed structure was built for the stand to fit into:

 

p1.jpg

 

At the other end of the belly pan some sprue tabs were added to hold the front securely in place inside the fuselage without any movement:

 

p2.jpg

 

At the back end of the panel some plastic bolts were used to hold the centre section (eventually with the wings attached too) into place. Here are the bolts:
 

n1.jpg

 

And the whole assembly fitted together:

 

n2.jpg

 

A bit of tidying up will be needed (note the ever-present filler!) but this section is nearly done. Here it is with the stand in place:

 

st.jpg

 

Wings and engines still require attention - talking of which, here are the engines which will be the next area I look at fixing:

 

en1.jpg

 

Very, very rough at the moment but with some effort these will improve immensely. 🤞

Matt,there are problems with displaying photos of your builds-none loaded here,at your Concorde build-the same from page 4 backwards,only the last page has photos of the "what if" decals

Can you fix?

Unfortunately not easily - my hosting provider changed ownership a few months ago and the SSL certificate which was part of the package is now no longer included. Without this, a security warning pops up and prevents the images from loading. They’re all there still, but to see them you need to click on the links so it’s a bit of a faff… All recent images are now hosted on Flickr, which is why you can the newer ones on the Concorde build. To fix the older images I would have to individually re-host all of them on Flickr and edit every post to provide the new links - this would take ages! I’m still working with my hosting company to try to get this resolved but starting to lose hope…

Yeah-opening the photos individually-works. Thanks

I’d better dig it out of the cupboard

Cupboard? How big are your cupboards! I'd have thought garage at the very least🤔.

It's a 'jumbo' year what with this and @Gimme Shelter and his amazing SAA 747 SP (which is a lot of acronyms)

It's not that big a model - especially whilst still in its component pieces!

 

Time for a look at the remaining items, starting with the wings:

 

wings

 

From the ruler, you can see the wingspan is about 1m (or 3' if you prefer!)

 

The panel lines are nicely molded, but the trailing edges and pylons need serious attention:

 

pls

 

Here's the undersides, showing the recesses for the engine pylons:

 

wus

 

Finally the engines themselves:

 

ngs

 

Plenty of work here to keep me busy over the winter!

Great to see your persistence on this!

Thank you! Not entirely sure if that's a good thing, but I will persevere a bit longer in the hope of producing a silk purse. Or at least a polyester one...!😁

 

Progress has been slower than planned, as I know what's ahead of me - loads of filling and sanding! Here's a better look at one of the engines:

 

eng1

 

The filler is a bit of a mess(!), as the tube was old and the filler a bit 'thick' - the only way to extract it was using a clamp!

 

sq

 

Note the new tube in the background, which will be used from this point onwards - this older stuff was adequate for rough filling, but not for finesse work.

 

I was also distracted one evening last week when I was planning to do some work on this, as Paddy McGuinness cycled past the village:

 

paddy

 

It would have been rude not to go out and support him!

 

One other unplanned task was to take a look at the stand, which is a ball and socket affair for easy positioning of the model. The tension should be adjustable with a screw, but unfortunately the recess the screw goes into has snapped off (shown by the arrow), making the joint too floppy:

 

std

 

A quick repair should soon fix this!

 

The next update will be after a sanding session...😁

Not sure that tube of filler in the background will last the project out! Good luck with it.

Thanks - the more I look at this, the more I think you're correct!😁

 

I sanded all the initial filler back and gave the engines a coat of filling primer to see how they looked:

 

yel

 

The exhaust cones are the worst fitting parts on these engines and will need the most work - there are some very noticeable kinks that need removing:

 

 

knk

 

I gave the engines a very aggressive session with some 240 grit paper to remove the excess plastic then reapplied filler in any low areas that I could see. The red marks are to highlight areas that need more sanding:

 

fil

 

It will be a battle, but I think I'll get these beaten into submission - eventually!

 

I have also fixed the stand, gluing it together and clamping in tightly around the ball joint whilst the glue set. It seems to have worked - the socket moves but is no longer loose:

 

std

 

Seeing as I'm using the filler at the moment(!), I'll try to hide the joint line and redundant screw hole to make the stand smoother.

 

Another sessions with the engines is next!

Progress on this one has been pitiful of late but some work has been done...

 

The stand is now filled to (partly) eliminate the gaps:

 

std2

 

 

Clearly a bit more work is needed here!

 

I have also improved the engines considerably:

 

gryp

 

Although again, more work is needed here too!😁

 

I'm hoping to have this ready for painting in the summer months when things have warmed up, so that gives me a good reason to get this finished!

I must admit, work on this one has been slower than planned...! 😁

 

A quick picture to show how the engines fit to the wing:

 

engatt

 

The recesses on the wing and inserts on the pylons are a different shape/size at each attachment point, to prevent errors, Once fitted there will still be some significant gaps that require attention!

 

When the engines are finally completed, my plan is to attach them to each individual wing to give me more room to manoeuvre when dealing with those gaps - as once the wings are joined together I will be juggling a huge piece of plastic:

 

wngss

 

As mentioned before, the pylons and wing trailing edges need significant attention too - they are a tad 'chunky' at the moment:

 

tte

 

I split the wings back into their upper and lower sections:

 

open

 

Note the clumps of polyfilla (!) in the pylons!

 

Some sanding took place to thin the trailing edges:

 

sand

 

The sandpaper is A4 sized!

 

I offered the lower sections into the central section to see how well (or not!) they fitted:

 

rdts

 

A good fit at the front, but huge gaps towards the rear marked by the red dots.

 

This area will need some serious bracing, so I looked out a few potentially suitable pieces of wood:

 

spar

 

I think the coat hanger will make a good starting point and once trimmed down it should fit into the centre section:

 

sspr

 

The areas marked in red will need removing to get the coat hangar to fit into the space. The separate wood spar will be fitted to the lower wing section in the hope that it can all be glued together at the end!

 

At least some progress has been made! 😁

Coat hanger? interesting solution, but HEAVY as hell

one of the things that bothers me-how to create a proper wing

insert reinforcement profile? how to create exact matching taper shape?

trial and error? chipping away a mm each time?

The whole model is quite heavy, so a section of coat hangar won’t make a huge difference.

 

I’m still not 100% sure how to brace the wing. I think I will epoxy a wing spar to the lower surface, aligning it with the central coat hangar spar. Once the upper surface is glued to the lower one the structure is quite rigid, so getting the wing spar to fit perfectly will not be necessary. I can then epoxy each wing into position and let the glue harden. I think it will be strong enough for a static model…🤞
