1:32 Hawker Siddeley Andover E.Mk 3A - 3D Print

Recommended Posts

More finessing on the nose section - now with a few layers of Filler Primer applied for final shaping.


A few blemishes filled with Revell Plasto filler.




These parts spend their life in the warm airing cupboard when not being worked on - to ensure that every layer of primer and filler is properly dried off at each stage.




As the nose is a very obvious/most looked at section of any model it's important it's as good as I can get it.


Back in a mo...

Now - back to those wings...


Earlier on I'd posted images of the assembled wings - minus the removed flap areas.




The flap areas need boxing in - both for neatness - and for strength.


I wanted to get these boxed in before smoothing and truing up the wings.


Photo below shows the Starboard wing (upper in photo) with new styrene sheet sections added - and Port wing (lower) withe the edges trimmed back to the wing surface/rear edge after allowing the Plastic Weld to dry off for 24 hrs.


Vertical section is about 0.5mm thick - horizontal is 1.5mm - wing now a lot stiffer - and straight along the rear edge.


Flaps will need to be drawn up in CAD and printed on my 4K resin printer - and will be fitted in the fully up position - so no detail needed inside the flap area.




Easier to cut sheet over-size and trim back - note that rear edge is not the trailing edge - that will be formed by the flap sections when eventually fitted.






Below is the Port wing - which has had everything trimmed back and a start made on sanding everything flush along the wing surface - in this case using 60 grit Glass Paper on a flat surface - a la vacform...






Hopefully get some of the 'low' areas on the wings filled and sanded later in the week.


Model on dudes!

The nose section is getting there - but still some areas to sand back/re-profile.




I've marked the areas to be reduced with the letter 'x' - and a dot where I need to add a little to the nose to make it just slightly sharper.






This is after a lot of pouring over photos and comparing with the printed parts.




I think it will still be a little 'jowly' in plan view - but I don't think it'll be *that* noticeable on the finished model.


If I can get these tweaks done by the weekend I can do some surface detailing of this area - and make a start on the interior... 


I might even get some filler primer on the wings. 


Really enjoying this - and the strength of the printed parts makes things so much easier than a vac!


Have fun...

Time for a long overdue update - I have been tinkering in the background - quite a bit of work, but not a lot of noticeable progress - such are the ways of a build like this.


Wings - surface sanded with coarse wet and try on my sanding bar - followed by a couple of coats of automotive grey primer - followed by a few coats of my favourite yellow filler primer:






Marks are where some slightly uncured resin (old stock - and may not have been mixed thoroughly enough) has bled through the paint. These areas have been scraped back to solid material using a small, round edged, scalpel blade.


These areas will then be filled with superglue and, once that's dried, smoothed off with a little filler.


This will be mostly hidden by the nacelles - but it's well worth stabilising the area to prevent issues in the future.


Other than that, they are coming along nicely and won't take much now to bet perfectly smooth, ready for surface detailing.


Prep work has also been ongoing with the fuselage interior - smoothing print lines and the front/rear joint in preparation for paint and detailing.




Current plan is to assemble the two half shells, add the tail unit, and clean the joints before inserting the floor section, with internal sections, from the front afterwards - a little like a ship in a bottle! 🙂

With the wings getting there it was time to try out the new Dart nacelles for the HS780 designed and printed for us by Ladislav Hančar:




HS780 on the left, HS748 on the right - quite a difference!




HS780 nacelle prints - port side upper and lower removed from supports - starboard side as supplied.


If you're not used to working with 3D Printed resin parts then all I can advise is take your time, use really sharp/fine side cutters, work methodically from one support to the next - and, whatever you do, don't drop them on a hard surface as they will probably shatter! Clean off any residual 'nubs' with a fresh scalpel blade and then true the surface with a good quality file.


Ladislav tweaked the fit of the original HS748 components to fit the One Man Model printed parts from photographs I took - and has got the fit incredibly close!




In these images the parts are just approximately placed in position on the wings - very pleased!










Some fettling will be needed, but nowhere near as much as I'd been expecting.  :)


Onwards and forwards...

More wing and fuselage prep this evening - and decanting that spray can filler primer into a cap so that I can do some pin-point filling with a brush - including some smoothing of the side window apertures..


Fuselage interior tube has been given a final coat of filler primer and, once this is sanded back, I'm going to spray the interior colours of White, Light Blue and Grey.


A dry assembly of the fuselage yesterday has shown that even with the rear and side doors open - it's only a few areas of the interior surfaces that will be visible - so I'm going to kick my usual OCD into touch on this and go for a 'looks good' were you can clearly see the surfaces and 'that'll do' for the rest.


This means that I may be able to get the Port and Starboard fuselage halves together - and the tail section bonded on in the near future - which will be a BiG step forward psychologically.


I'm back to not being able to put this one down at the moment - but letting things dry fully between filling and sanding means I have time to do some other stuff too...  :)


Pix when I've sprayed the interior colours - and I have the wing sections fully prepped and back into grey primer.

I just gotta say: this is an ambitious project.  It seems that you are spending quite literally months just to get the surfaces ready for painting, which augers ill, I think, for other would-be purchasers of One Man Models products.  Is Ladislav Hančar amenable to producing his components in 1/72 also?  Alex

No, that's not the issue at all!  :)


Surface prep is reasonably quick in most areas using primer and wet and dry. Yes - it's work, but it's really not that taxing.


The model is taking time to get to this stage largely because of the modifications I've chosen to make - on a large scale model. It's rare that I leave *any* kit alone, let alone a very limited run 3D printed one.


I'd hate to put off prospective customers - Toshihico has designed and printed a great product IMHO - but you need to go in eyes open and understand it's a canvas. Way better than scratchbuilding, or a vac/resin kit as a starting point in my opinion - but they *will* need modelling work. Go in with that mindset and you'll enjoy the project.


I've chosen to remove the nacelles and flaps from the wings - so that's a lot of clean-up required from that - and that has taken most of the time.


I strongly suspect Ladislav could run off some engines/nacelles in 1:72 - drop him a line, he's a really helpful chap!  :)


Have fun,
