Airfix Short Stirling Tug completed WIP.
Posted by rtfoe on Wednesday, May 12, 2010 7:51 AM

Hi Guys,

Thanks to Steve, a fellow modeler from UK who kindly sent me the kit, I'm able to build a tug for the Horsa glider I built earlier.

The packet arrived and was pleasantly surprised that the kit came in grey.
Took a day or two off during Chinese New Year and tackled the kit with some simple add ons and scratch builds to bring the kit up to present standard of current kits.

Areas of build were the cockpit, rear turret, deleting the top turret, re-scribing panel lines, sanding down of the rivets, adding interior for the rear entrance, refining the cowling flaps.
 
For those who don't know what a Stirling Bomber looks like, below is an example.
I'm attempting to convert the Mk3 to a Mk4 and probably the one that is not the full glazing and only replacing the front turret with plexiglass.


The kit that I'm using and is the only one of it's kind that I know off is an Aifix kit in 1/72nd scale.
The alignment of its panels and rivets all match when put together, surprizingly for a kit that's nearly as old as me. There are some gaps here and there that can easily be fixed with putty and plastic strip.
The only grouse I have is the lack of interior detail which I will tackle.

Scribing was done using the Dymo strip as a guide and a pin locked in a pin vice.

Then I sanded the rivets and any raised lines left over from the scribing...washed the parts with a tooth brush to get all the muck that had built up in the grooves.

The rudimentary cockpit was put together. Detailing will be done at a later stage.

I added some ribbing to the super structure.

Dry fitted to see how it looks.

I scratch built some scaffolding for the rear as I wanted to pose the rear door open. This was done with plastic strip and textured Evergreen strip.

Notice some of the tiny windows...they're peppered all over the planes body. Thought of using crystal clear for this but instead I'll use the kits clear parts as it looked good the last time I used them on my previous stolen kit.

Look at them windows...man so many to mask later.

There were some unsightly sink marks on the wings that I had to fill.

I used the tape to mask off so the surrounding details will not be sanded off.

Tamiya putty was added.

Sprayed the interior with interior green(should be more pale) and gave it a wash with a mixture of black and brown poster color.

Then I cut away the top turret opening.

Added plastic strip.

The plastic strip was supported by plastic beams glued across the bottom.

I did the same painting to the cockpit area with the same wash.

Added seat belts and a paper map just to spruce things up abit to make the rather dull cockpit lively.

Another angle...I've only dry fitted the halves together with tape.

Thanks for looking. C & C welcomed. There's more to come for instance the nose modification and the tail turret plus the rear door detailing.

Cheers,

Richard

That looks great so far. I had a similar masking exercise with the Airfix Sunderland recently, but at least they are round, so I used a hole punch to make the masks. One way is to put a dot of white glue on each window, and pop it off at the end.

Thanks Rick, more progress to come.

Thanks Bondoman, yes that's what I did to mask of the windows. The white glue is a technique I learnt by chance when a blob dried on the surface that I was spraying and it peeled away easily.

Scorpiomikey

thats a crap load of windows. you poor bugger. cant wait to see more

Ha, ha Scorpiomikey...the window don't scare me, I just got to make sure I don't get any cement on it. The windows aren't the hard part...it's the turrets that's a bummer with Airfix...lots of up grading.

Cheers,

Richard

While waiting for the sub assembly's to dry I had an hour to improve the engine cowling flaps. The original is kind of thick and the surface detail very soft.

With a motor tool I thinned down the flaps/slats...

...had to be careful and maintain the same thickness throughout. I cleaned out the burrs with a hobby knife...

...I chucked in a circular saw into the motor tool and sawed the slats then using masking tape as a guide I scored the joint and sanded an indentation at the base of the slats.

You can compare the before and after of the cowling in this pix. The last one on the right hasn't been modified.

Did you know that the wings of the Stirling were deliberately shortened to fit into the British hangars of that period. The result of that produced a low surface ceiling performance which plagued this bomber. Even with this handicap the Stirling was rushed into production because Bomber command needed heavy bombers and the Lancaster was still the Manchester with two engines.

Ahh... the English.

More updates on the cowlings,

There were two racks of pistons per engine that I glued together... painted them black and dry brushed with silver. The firewall was painted interior green.

Painted all of them like factory :lol:

Then I painted the cowlings with interior green...

...then with black I sprayed it to look like grime and soot deposits.

The propeller needs sanding to get rid of flash.

More progress. This time it's the nose conversion from the nose turret to the plexiglass.

I did this without glueing the halves together but just taping them with masking tape.

I then sawed away the upper lip extention. Notice that I had drilled and carved away the turret base supports.

....then I traced out the outline of the plexiglass dome onto three blocks of balsa wood...glued them together and carved away the excess. My blade is so rusty, I need a tetanous jab by just looking at it. :lol:

I sanded and filed until satisfied with the shape and look, everytime checking it against the reference drawings and placing it on the nose of the kit.

All these years of modeling and I've not vacu-formed clear parts. I was going to attempt it the first time.

Built my homemade vac-form. Made it from Ferrero Vocelle container. Drilled some holes at the top and a large one for the vacuum cleaner nozel attachement.

Close up of the perforated holes and the master...the masking tape is to cover the extra holes.

Ha Ha!!  My first attempt is going into the bin... :lol:  :lol:

Aahhh!! the second attempt was a success...need to polish and dip in Future.

Now I can vac-form parts anytime. the plexi-glass will be fitted when the the halves are joined in a later post. That's all for now till later.

Cheers,

Richard.

There are two things that may have caused the interior green to look intense. One is the light source may have been too close and the second is my tweeking of contrast in photoshop may have done it. The other possiblity is the interior green color I used could be wrong. The British had their own interior green that was much more pale and dull. The intense green doesn't show up in real light and after the canopy has been placed.

I think that someone else is me. Same thing happened to my SBC-4 Helldiver.

Cheers,

Richard.

quite possibly, that was the biplane wasn't it? a close look at the image with the window on reveals your right, its not so intense when the lights not directly on it.

What was stopping me from putting the fuselarge halves together was the front perspex and the rear turret. I've done the front perspex so now you will see how I tackled the rear turret.

The kit provides a very basic assembly so I had to improve on it...

...a figure was used to hold the four brownings so I cut the body away and left the moorings for the guns...I also shaved the shell casing chutes...

...colored and weathered the interior...

...cut strips of plastic card, measured and glued the sections...

...accidently got some glue on the glazing so lots of fine sanding and polishing ahead...

...other angle...

...dry fitted just to look see.

I was quite satisfide with it and proceeded to closing it up, fill up gaps, sand and paint.

I dipped the rear turret clear part into future and placed it on a paper towel to drip dry.
Lucky me it took out most of the scratches and smudges. I painted the inside and outside paneling before gluing to the bulk head.

Then I added more detail to the gun assembly with a front deflector and sight...

...painted it black...following picture shows another angle.

Glued and clamped it down as the sides of the clear part stuck out.

Then last night I masked the canopy edge and puttied to later sand level to main bulk head.

Next after sanding I masked and painted the panels.

The little turret has finally been sealed, puttied and painted. The gun barrels were drilled with a 0.2 drill bit.

Then the windows were glued down...make sure to add more glue...don't want it to pop in once the fuselage halves are joined together. :lol:

More windows <_<

I finally joined the halves together...made sure the fit was aligned with tape.

For the windows on the exposed cockpit, I painted the back edges with interior green so it wouldn't stand out. Some purist would cut away the extra plastic...I'm not that mad. :lol:

A lot more windows <_<

I botched this part by accidently smudging the third window with glue. I sanded and polished it but it still is quite hazy.

Aahhh!...the culprit or one of it that stalled the building process. The other is the plexiglass for the front.

I sprayed the surrounding area of the turret mount in black first so that it would be simpler when it came to masking later on.

Next is what I dreaded...puttying and sanding of the body and wings.

C&c welcome.

Cheers,

Richard

Richard, check out Quickboost. They sell beautiful sets of .303 and .50 gun barrels. Oval and round holes. I keep a stock handy- it's remarkable how fast you can go through a set building a big "heavy".

I like that turret. I have built them from the ring up, but I like your method better. One thing, I believe the interiors of British turrets were black.

Posted by rtfoe on Monday, May 17, 2010 7:08 PM

Thanks Bondoman, I'll check out Quickboost. This Stirling only had the rear gun turret  remaining after the conversion so it's only four barrels thats needed.

Black is it? That's the trouble working with only B/W photograph reference material. If I had painted the interior black, I would have made it a shade lighter so the inner framing would show up against the outer frame...that's me. Thanks for pointing it out. Now my Lanc, Halifax and Wellingtons will have the correct turret interior colors.

Cheers,

Richard

Richard your Stirling is really looking GREAT!!!! Have been meaning to grab that kit after seeing my mate's build in a pic. Will be watching with great interest and taking notes. Btw, what was your heat source for the vac-form, a hair dryer? Have also heard of using an embossing gun found in the scrapbooking section of craft stores. Often wanted to try that technique out myself but just haven't worked up the nerve. Awesome work!!!!Toast

Thanks Lt. Cdr Ritchie. Glad you have a reference to follow when you get the kit, if you don't mind it's in-accuracies.A hair dryer would be one very good heat source. I used the flame from a tea light with mixed results. Have not heard of an embossing gun before. Go ahead and experiment...the good thing is you can try over and over again till you get it right. Cost won't be the issue if you've got extra CD covers lying around.

More updates.

Before puttying and sanding I added some shims and card to gaps. The following pictures show these areas.

The tiny gap on the ex-top turret position closed with slotted thin card.

The canopy didn't fully fit to the back. Card was added.

The front was too thin so I shored it up with card as well.

Used the cowlings for support to maintain dehydral for the tail planes.

More to come later.

Cheers,

Richard

Even more updates...

The big Stirling put together with dry fitted wings and engine cowlings...

The flaps are workable and that leaves an unrealistic gap between the wings and the flap...

Some thin plastic card glued in place helped fill this gap...

The tail sections also got some card fillers.

The Stirling taking shape...canopy masked and stuck on...

So are the front plexiglass observers and bomb aimers station...

Close up of the amount of sanding to correct the nose section...

Undercarraige doors were thinned out...the right one is still in its original thickness...

The intakes had dimples/sinkholes that were filled and sanded...phew!! lots more to go...

Cheers,

Richard

Yes they would still be opposite to each other when parked as back then they would have been mechanically linked. Wasn't until full hydraulic controls came into being that they would have been in the same positions when parked. I work on 747s and when they are on the ground after shut down the hydraulic systems bleed pressure and the inbd ailerons both slowly droop after awhile. The otbd ailerons remain in the neutral position. Soon as the appropriate systems come online the inbd's snap back to center and then work accordingly.

Thanks for the heads up. Very helpful indeed. I can understand the older planes were literally "fly by wire" SmileWould you happen to have a list for fully and non hydraulic assisted WW2 planes. I think the P-51 would have been hydraulic assisted as many modelers mention the main undercarriage doors swing open after a while when parked.

It's a good thing my ailerons aren't stuck down, I can move them depending on the direction of the vertical tail stabiliser. Would the tail flaps(?) behave the same?

Cheers,

Richard

The tail planes are elevators. They move up and down together. These kinds of things generally are pretty centered on the ground because they often have chocks or locks installed to keep them from flapping in the wind.

Also the amount of deflection it takes to change flight attitude is less than you would think, after all they aren't supposed to slow the plane down. Esp. a big old slow bomber isn't set up to make radically unstable moves like a fighter.

The rudder on the vertical stab doesn't really follow the ailerons either. They create roll while the rudder changes the heading. I deflect my rudders usually, just to give the model a little life and they seem to be that way in pictures, but don't do much to the other control surfaces.

Something I do like to do, although it takes work, is to open all of the flaps around the base of the cowls.

Now you need a Hamilcar glider!

Cool Bondoman,

Now I'll know how to pose all my aircraft. I've got the Horsa done up to accompany the Stirling. Will post it next.

More updates for you guys...

Just prior to spraying a layer of surfacer I masked the little windows with white glue diluted with a bit of water and applied with a toothpick.

One window has the white glue settled and beginning to dry clear and others have freshly applied glue. The tooth pick helps for easy application and to tease the glue to the corners of the edges.

It works just the same as masking frisket. When the painting is complete just peel off.

Basically it is the scratch building of the tugging arm at the back of the Stirling. Every aircraft had it's own design specifically as I had noticed in a friends Airborne book.
With what ever reference I had, mostly drawings this was the best I could come up with.

Close up and not weathered yet.

What it looks like from underneath. I'm guessing the cable was attached some where along the tail wheel spine which was also scratched in.


Other additions were the antenna chin mounts with styrene rod.

I might add these antenna on the front nose too.

Pre-shading.

After this I couldn't feel my fore-finger :(  Ouch!!

Example of another masking technique. :lol:  This angle makes it look like a bull with horns.

Next to proceed with invasion stripes.

Cheers,

Richard

More updates. I know you guys want to see more color...here is some progress spraying the invasion stripes and masking...

...spraying the dark earth and masking...

...results after all that masking and spraying...

...the glider in the background and the tug in the front...

...some lift off when peeling...my sweaty hands must have left some finger oils so the paint didn't stick well. I noticed that paint that was thinned with commercial thinner bites better and doesn't lift off.

I'm going to decal and then weather. The Stirling will look more weathered than the Horsa being in service longer. It's also got radial engines that spue lots of oil smoke.

The sharp camo was done with blu tac masking...the rest of the plane was masked with tape and below is the result of tape collected for just one of the sessions.

More progress during one of my weekends.

Still lots more to do. Side decaling and weathering of the undercarriage and cleaning of the canopy and windows. Actually the close up pictures sure reveal the roughness of the finish. I've got to burnish the cockpit frames and polish it down a bit. Still to highlight the black areas and weather the engine cowlings, propeller tips and hub. The exhaust hasn't been attached yet.

Cheers,

Richard

Thanks Lt. Cmdr. Richie,

Here are the last set of pictures and not before I show you the blunder I made with the camo. Something didn't look right. With all the reference at hand I still made a big blunder. The camo should be in reverse. Looks like I had to re-mask and spray again.

Can't leave it as it is as RAF aircraft all followed a certain template in camoflage. I finally took the guts to rectify the camo mistake . Remasked the canopy and sprayed. At this point I gave the kit a water color wash with black/brown mixture and soap detergent.

Close up of the engine nacelles. Notice that I added the engine bracings commonly found in Bristol Hercules engines.

This is the left wing...

...this is the right wing.

Close up of the aerial bracing and canopy.

The wash. Looks like not enough soot from the exhaust. Will airbrush this in later.

Drama shots.

Airbrushed the soot and oil stains to make it look more grimy.

Finally can close the book on this build. I'd build an Airfix kit anytime.

I hope Steve who sponsored this kit(Thanks again Steve) is pleased with it's outcome.

Cheers,

Richard
