Look up Onmanmodel on eBay. I have 4 of his kits, the service and packaging is very good. 

I've just bough his 1:72 HP42 kit, so hopefully it'll arrive in a month or so and I'll get cracking. 😁

 

So Iain, do you simply wipe the surface with a fine smear of Revell filler then sand off? Would PPP do as well? Any special tips for a newbie in 3D printed stuff, grades of wet'n'dry etc?

Watching this one.  Have been eyeing up the 1/48 version.  But north of £120 means it will stay a pipe dream for me.  Would look good with my Italeri Herc.

Hi gang,

 

Apologies for lack of posts - a bit more progress:

 

Several areas I'm keen to find info at present, as well as anything that might help with the tail area, the most immediately required was to confirm the internal Layout for the E3/E3A conversions as it looked like there was a second console added next to the navigator's position for the AEO that managed the approach calibration equipment.

 

To that end, Ebay came up with some help, for very little outlay, in the form of three old period publications from the 70s/80s:

Most useful for the Calibration E3 versions was the following:

Unfortunately the quality of magazine photographs/print has improve hugely over the years, and many of these images are a little grainy, but they do help!

 

The latter article certainly confirms the different internal layout on the 115 Sqn airframes - if not the specific details.

 

I've just joined the 115 Sqn association page on Facebook to see if any ex. members have any suitable details.

 

But - it is progress, as I've made some decisions regarding the internal sections as printed - and need to get some fresh scalpel blades out for more cutting.

A little more progress bubbling away this week - but I'm going to take a break from sanding for a few days and pick up on some other projects for a few days...

 

More primer on the tail - and a start made on opening up the slots for the tail door hinges:

 

48b427_60c2af1b8b3a4253a47d860cbd7d20d4~

 

48b427_f441fae97ce6498bb3cce9c2ad678198~

 

And yet more sanding of detail areas on the tail interior - with home-made 240 grit sanding sticks to get into nooks and crannies:

 

48b427_67a8d1a5a7d944e5ba0747b55e3e7df5~

 

Interior fuselage sections after initial clean-up and a coat of primer - can see what I'm doing now!

 

Note - these are photographed upside down so I could capture more of the relevant detail:

48b427_82df57bd87204577946afd19295b2ca4~

 

All external aerial details, along with external hinges and rain channels have been removed - to be replaced with finer detail later in the build.

 

48b427_8db9b98c17ee4832922da35bb4d5f552~

 

And getting ready to remove the internal sections - to be re-arranged later:

 

48b427_63f08d0011f748ed830bc1fba653f0e6~

 

And, whilst everything out, I couldn't resist a quick fuselage shot!

 

Too big to fit on the photo background I normally use at home:

 

48b427_0218eb92a13c4040a3c6e157fcbe4767~

 

Oh, and after a bit of a search, a stock of 0.25mm/10 thou clear PETG sheet has arrived - more on this to follow...

 

Have fun!

OK - I was planning to put this away this afternoon, but got sidetracked and ended up following more of Baldricks 'cunning plan' and creating more parts by cutting up existing ones!

 

The tailpane...

 

The sections of elevator were removed from both the inner sections of tailplane (removed from the fuselage tail earlier) and the separate tailplane sections themselves.

 

This was really hard work on the inner sections as the 'skin' is quite thin here - and I had to do some re-bonding of broken sections afterwards.

 

The outer sections were an absolute walk in the park as they are printed mostly separated along the hinge line and so the main cuts have to be made to the hinges.

 

So, more parts:

And then, well, I had to glue something back together - so I now have mostly complete port and starboard tailplanes and separate elevators - to be left for a few days to harden off:

Hello Iain,

 

 

Thank you for this in-progress post, will be most useful for my 1/48 Andover that is now on his way.

 

According to Shinimizu it'll have the corrected tailplanes.

 

Do I spot a recess on the fuselage sides ? To include a strip of clear plastic strip for the windows maybe ?

You got the 1/48 one - that does look good.  It would be interesting to see how it compares to the 1/32.  It’s a bit pricey for me so watching is probably as close as I am going to get!

Just caught up on this one. Loving your work, I have a few of his kits but don’t have the balls to start them yet. Think I’ll get one of these though, had planned on the grey/green Camo 51sq frame for my 1/48th kit but think It will look better in 1/32nd.

Hi Iain, Any update on this kit. We're still following with great interest. 

I've ordered the 1/48 kit and should have it soon.

Just a few bits and bobs - I've been mainly trying to find reference material on the interior AEO's position in the E3 Variant - as well as any more tailplane detail - and still drawing a few blanks.

 

I think I'm getting there with the tailplane - with the various elements/angles/interfaces now making sense, after some surgery and scratch-building:

And some filler-primer on the interior of the tail:

Another update to follow in a mo...

With a fresh supply of 1.5mm clear HIPS sheet I thought I'd take a break from sanding/cutting/reinforcing big chunks of ABS and have a play with a glazing - to see if this particular cunning plan was going to work.

 

I'll let you guys be the judge by the end of this post.

 

The quality of clear parts can make, or break, a model and so I usually spend a lot of time on a project trying to get these as good as I can get them.

 

I try to use the most suitable material for any given purpose. The fuselage windows I'm going to do as a single strip each side - so wanted a clear, non-yellowing, plastic that would easily conform to the single curve of the fuselage - and could be glued to the ABS fuselage prints with solvent. So - 0.25mm UV Stabilised PETG sheet will be used.

 

For the cockpit windows I wanted something absolutely flat and distortion free - and something I could use wet and dry followed by polishing with Novus Plastic Polish. PETG doesn't like sanding/polishing at all - but HIPS does - and at 1.5 mm thick substantial enough for shaping and to hold it's flat shape on fitment.

 

Add to that the trick of 'edging' the clear part with a permanent marker that I've been using for years to make neat edges, as well as create the impression of thinner 'glass', I thought I might have the tools to make a go of these.

 

Cutting the first window:

 

spacer.png

 

An oversize section was laid over the window aperture and the edges marked on the surface with a new scalpel blade.

 

The section was then trimmed back using Tamiya side-cutters to within about 1mm - then the edges taken back with the T-Bar sander - bit by bit, with lots of trial and error - as well as corner rounding, until it fitted absobl**dy perfectly - even if I do say so myself!

 

Here it is just press fitted in position - took about an hour - but hopefully looks OK!

 

spacer.png

Final bonding will be with a little solvent touched into the corners and into the joint - followed by a polish.

 

So, I think there's another challenge sorted, perhaps...

 

Blue skies!

Yes - recess is really useful. Needs cleaning up and deepening a little - but I'll be skinning with 0.25mm PETG before masking the windows.

 

Corrected tail is still out IMHO - and I'd still be cutting up as I have so far (I have one of the corrected prints).

Hi Iain

 

First time I've seen anyone doing this type of kit. Seems like a 21st century cross between a high end vacform and a short run injected kit... though the printing looks very sharp.

 

It's interesting that you say many of the movable parts (on the real aircraft) are mostly separated in the print. I assume that's because he designs stuff like a traditional kit (i.e. separate parts for elevators etc) but then brings them back together for the printing.

 

For windows, could you save some time/effort by asking the chap to print out the patterns from the 3D model? He could send a file which would not only serve to cut out your glazing, but also be used to cut a set of masks.. seems a bit of an oversight uses of the data to me... It wouldn't be like he was giving away sensitive data from the model. Just a thought.

 

Will watch this.

Hi Matt,

 

Long time, no speak!  :)

 

The 'kit' includes pre-cut 'windows' in a thin, clear, material (along with frames in white plastic).

 

I could have used those as patterns - but easier to mark and cut new ones to fit as the openings have been sanded to remove print texture and this way, I know they fit perfectly.

 

I've gone for thicker material so they end up as optically 'flat' as I can get them - and blended in with surrounding fuselage.

 

It's no biggie!  :)

Aha. I see.. makes sense...

 

His stuff is very interesting - well some of it, but the thought of getting hit by 20% VAT on top of the listed prices pushes them a bit out of (financial) reach..

 

I love the HP42 and Scylla.. :)

Hi Iain

You deserve the madness reward only for smoothing all that abs; and I am complaining about removing only a few hundredths of a millimeter on my 3D resin staples. Joking aside, congratulations for the excellent work I have done so far, I will follow you with interest, even if only to see if you come out of this adventure healthy😂

Apologies - just spotted I haven't updated this thread - and there's been progress...

 

BiG news since last update was that Ladislav Hančar of LACI models has created some superb engines and cowlings for the HS-748 and HS-780 in 1:32 for the One Man Model 'kits' - and I now have a set of each. I'll come back to those shortly.

 

What I did need to work out was how to fit these parts on the One Man Model wing.

 

So, 'Operation Dart' began...

 

This wasn't simple - as the One Man Model parts have the nacelles/cowlings printed contiguously with the inner wing sections - front and rear each side.

 

48b427_5ee9f16fa7574023ad057e057d958b20~

 

48b427_0ca11255c2f6448fa9d9fe42508c1047~

 

So, out with the razor saw - and some careful cutting:

 

48b427_45e5cf1d45a64baeb9d2299aeb62d9fd~

 

Which gave us this - surfaces where cuts have been made need dressing off - that will come after some important stabilising work - more on that shortly.

 

48b427_f8ebbb827d5e4f7883455881b9f71caa~

 

48b427_2ce18de332e6495eb8667987c371b697~

48b427_fae248540a1b43be8703e7c27d69610e~

 

Leaving four components to make up the Port inner wing section.

 

48b427_20179fbd7c064290a0850e922d4fb904~

 

Disappointingly on my inner wing prints there is no internal 'fill', or structure, from the print process. Even before modification, you could squeeze the upper and lower surfaces of the inner wing section together - and they would 'give'. Even looking at the parts when they first arrived, you could see the upper and lower surfaces 'bowing' out'. Cutting up these parts confirmed the interior is completely hollow - disappointing as a fill is easy to add at the print slicing stage and would have helped a lot with strength - but we have a 'plan' that I'll come back to...

The leading edge pieces of the starboard wing inner section have been bonded to the main/rear section - using Plastic Weld cement liberally flooded into the joints:

 

48b427_2612d8b8d0cc47d783da6d4094a14463~

 

You'll probably notice something else...

 

If you look at the rear of the opening where the upper cowling has been removed, the printed in flaps have gone:

 

48b427_fcc8771ecbf24a159fbebb9543b2bbb4~

 

The trailing edge on the flaps - and ailerons - is quite thick - and the strengtheners are the wrong shape - so I'd decided a while back that I'll draw up new flaps and print them.

 

This meant removing the printed-in sections, before we can start on building up and strengthening the inner wing sections again:

 

48b427_0fb634c36cf94cb3b75907a870fd3fa3~

 

48b427_c81155a6ac264dcdb3ffa4bea19d63c1~

 

Next stage will be to 'box in' the section where the flap section has been removed.

 

But, in the mean-time - a quick test positioning of the LACI nacelle parts (note - these are the HS-748 versions - I'll cover the correct HS-780 set a little later) on the inner wing before the latest progress.

 

Width looks spot on compared to the One Man Model parts - but some tweaks were needed to the fit of the LACI parts to the wing cross section:

 

48b427_a4ad9535537543fd91c58155f9e96dbf~

Looking at orientation on wing - thrust line, alignment in vertical plane from the front etc. - again - these are prototype HS-748 units, not the ones that will be used.

 

Some tweaks needed - but given the parts weren't designed for this model, or scale - actually pretty good!

 

48b427_336bed03592149f0be9dee66ff963d01~

 

48b427_58756f7c70ab48b4a7d87a6321f315a5~

 

And a final 'overview'...
