    Hi, guys... so my next build will be the 1/72 scale Arado Ar232B from the French manufacturer Mach 2; there will also be some additional parts from the German-produced Airmodel vacuform offering of this aircraft, and although the use of parts from the latter will be minimal, they will nonetheless be beneficial to the model.

    This kit, despite its 'rough round the edges' reputation, has endured since at least 1991. I had it in my collection at least the best part of 20 years ago, but in keeping with several models that I've revisited in more recent times, I am looking forward to taming this one and producing a decent outcome.

    This will include improving both the lamentable cockpit detail that comes with the kit and also the construction and presentation of the undercarriage parts in the lower fuselage. I would like to try and show off the complex control surfaces on the wings, but that will require a bit more consideration as to whether or not it would be feasible without messing up the entire kit. The intention is not to produce complete replication of detail in the afore-mentioned areas, but rather, sufficient to effect some much-needed improvement to the model.

    So far, I have done as much scratch-building of the fuselage interior as I feel will suffice. The fuselage has been closed up and new pieces have been made for the 14 lateral transparencies, seven on each side and weights have been added in to hopefully allow the model to sit on its tricycle main undercarriage without tilting backwards.

    I expect to have the initial photos of the build added in sometime over the next few days. As ever, I hope you will look in when you have time, and enjoy the build as it progresses.

    Regards,

    Paul

    Amazing entry, my friend @paulh! Have the same exact kit, so your build will be quite an inspiration (of course, opting for a result half as good as yours at best, since my skills are way lower than yours).
    Really looking forward to this wonderful project!

    Well, here are a few more photos. I have others showing the work up to this point, but they're on my now-no-longer-properly-functioning mobile phone! That's what happens when it gets accidentally dropped into water... ho-hum :-(.

    Everything works fine, except the upload function, so all my photos and a few video clips of this build are currently hostages to misfortune. Once I pay the ransome to the god of mobile phones, thus securing the release of my captive images, I will add them in here... diplomatic manoeuvring is ongoing... :-). So, largely out of necessity, these images only show wing details at this point. The first two photos show the underside of the right wing. The necessary removal of offending lumps of plastic from the moulding process was addressed first. Then the undercarriage bay was added in and sealed round the edges. Small lead fishing weights were added into the lower wing nacelle spaces and secured with super glue, all of the above happening after I removed the control surface sections from both the top and bottom wing pieces. The resultant gap was blocked off using plasic card and any small gaps filled in and sanded smooth. There are several indents in the plasic on the external surfaces, and these too were filled in. Once dry and sanded, I took medium and then fine grade wet and dry paper and lightly sanded the entire assembly as it has an ever-so-slight grainy texture. Some panel lines suffered a little but these have been easy enough to revive with some careful rescribing.

    With there being a greater amount of plastic removed from the wing undersides than the uppersurfaces, the control surfaces require to have certain sections reproduced to make them complete again, as I hope to show them deployed, rather than in neutral position. In the fourth image, the wing is viewed from below, and the detached parts are shown laid out in the positions they will eventually fill. The fifth photo shows the interior of two of the pieces, and how the recreated uppersurfaces have been attached at the correct position by using small plastic card inserts to support them. Their leading edges will have filler applied along the length of the piece, then sanded to a curve to finish the process. The final three photos show the opposite wing from beneath, similarly tidied up and then closed up. Its control surfaces were started first, therefore are shown at a slightly more advanced stage.

    All in all, the model is progressing slowly but rather well. The left wing is now attached to the fuselage and the model is starting to feel a little bit heavier with the added weights coming into play.

    So, that's it for now. I hope I can get the other photos posted soon once the technical difficulties are resolved. Thanks for looking in.

    Regards,

    Paul

    Thanks you, guys, for your comments. I am pleased to say a partial resolution to my technical issues was achieved and I got my pics uploaded. So, the images below show the other aspects of the build so far.

    The first shows the process of addressing the side transparencies. Each space had to be enlarged slightly, and then circular windows cut from clear plastic were fashioned using a hollow punch from a leather-working set. What fun that was, belting a hammer onto the punch to create each window...! 🙂 In truth, the punches only cut so far into the plastic, but sufficiently so for it to be easy enough the cut them free and tidy them up before inserting them into position. I may have to revisit this area as the surrounding edges in their respective locations still look a bit rough. Anyway, that's an issue for later, before painting the kit.

    I was then able to cut open the under-fuselage space for the multiple coupled wheels, which were such a feature of this design. Weights were then inserted at the front of the large cut-out area, then boxed off using plastic card. The area at the very front of the opening, where the large nosewheel will be attached, had prominent circular cut-outs, so I included these in the plastic card inserts in that area.

    One of the big issues with the kit is the forward canopy which is, sadly, both ill-fitting and sufficiently opaque as to be unable to see much through it. I have hope of remedying that concern, but I'll keep you wondering about that for now. Needless to say, the cockpit area absolutely requires copious amounts of TLC. To this end, so far I have managed to modify and manipulate various items from the spares box to produce something more akin to the actual layout, but by no means an accurate representation; the housing for the main undercarriage's rear leg appears to have been included with the model, but it is woefully inaccurate in dimension and location; due to the incorrect position and rendition of the kit bulkhead and cockpit floor, the former stands too far forward, thus eliminating any detail or space for the installation of the gunner's position for the dorsal turret.

    As a result, I decided early on prior to closing up the fuselage, to scratch-build some of the basic internal ribs and bulkhead detail which will be visible when the canopy is attached, as well as the platform where the gunner's stand was located. This work was naturally a little time-consuming but ultimately, I hope it will give a better impression when all is said and done.

    And now, as mentioned in the previous post, the left wing has been permanently attached and its control surfaces are nearing completion. When I am happy with the opposite wing's control surfaces, that wing can also be attached, at which point I can start to believe that the kit is well and truly up and running and I can move on to other areas; the main undercarriage may need some attention, the under-fuselage area will require to be divided up into compartments for each of the double-wheel assemblies, and then I can turn my attention to the engines and tailplane.

    So, more images in due course. I hope you like the model so far... :-).

    Regards,

    Paul

    Great additional work, Paul @paulh
    Definitely well worth the amount of time you put into it.

    Well, it's seems like ages since I posted into this thread, but in between attending to necessary day to day things, I have been making some lumbering and monotonous progress with the build.

    The first issue was with the engine cowlings. The kit pieces are very reminiscent of the old Italeri Do24 flying boat cowlings, and their rear area where the cowling gills are located show these in the open position. But I've never been a fan of their appearance so I decided to substitute them with spares from RS Models' Do17P kit. These look better to me from the front, but the gills at the back are moulded closed. The cowlings for the BMW-Fafnir engines used in the Ar232B variant appear to have no gills as such, but do have raised sections as exhaust outlets. From all of the images of the 'B' variant I have seen, there are none that show good close up detail of the cowlings, so I have had to do some guess work as a result. I bought two very good, and very technical, publications on this aircraft, but almost entirely, they focus on the earlier, twin-engined 'A' version, so in respect of the engine cowlings, they are no use at all.

    Anyway, I started off removing the rear strip from Airmodel's vacuform Ar232 kit - they offer the best suggested layout of the rear area, and the curve fits the rear curve on the RS Model's nacelle. However, they are rather flimsy as you might imagine, but I wasn't sure they would look as good as I would like once finished. The first image below shows these pieces while I was trying to match them up.

    Ultimately, I discarded that approach. SInce I had spare Do24 cowlings handy, I cut the rear gills off, sliced them up and reattached them at the areas where I felt they should be, as best as possible, raising only the 'open' sections and modifying the other pieces to sit 'flat', as if in closed position and matching the curve of the nacelle. Any small gaps were filled in and sanded smooth. I still have reservations about how good they will look at the end of the day, but I'll only be able tell when I get an undercoat of paint on them.

    Turning to the undercarriage, I have started to work out how best to assemble the under-fuselage wheels. As you can see, I have cut dividers from plastic card and numbered them so I know which ones fit best and in which order. Small tabs were cut and attached to the top of each divider. You can see them dry-tested in the images below. The upper tabs will require adjustment to improve the look. The underwing area has had small strips of adhesive tape attached to give some basic sense of the framework in that area.

    As you will appreciate, these attempts to adjust and improve are fiddly and time-consuming, not to mention very frustrating at times, but I hope the endeavour will be worth it in the long run.

    Thanks for looking in... :-).

    Nice job on the cowlings and wheels, my friend @paulh!
    You surely tame this very challenging kit!

    Some great work done on the cowlings and undercarriage, Paul @paulh
    It will definitely be worth the time and frustration you put into it.

    Looks great, Paul (Paul @paulh). I am looking forward to following your construction. I think you have to be mentally ready to start some kits that you know might be challenging. I think you will be able to work through all of the challenges and come out with a real standout.

    Guys, thanks for your previous comments. I have some more images for you now. A lot of time recently has been spent seemingly going over and over some parts trying to get them looking good, thinking I'd done that, only to find another issue further along on the same piece... I dare say we all get a little bogged down from time to time.

    These few photos show the progress to date. I've added in the pilots' seats, control columns and pedals. One of the seats tried to escape but I managed to retrieve it and will reinsert it at a later point. The engine cowlings are more to my liking now and I sourced better looking engines from the spares box. Intakes on the cowling undersides have been made from plastic card.

    Some tentative work has commenced on the main undercarriage items, with replacement wheels and the plastic legs and wheel attachment points being removed and alternatives being fashioned from spare brass parts; the nose wheel leg has been dismembered, keeping only the revised lower section. The upper section has still to be completed; the new 'horseshoe' attachment to fit around the wheel was created from spare plastic from the sprue, gently heated and manipulated into the correct shape before being tidied up with some sanding.

    The third and fourth photos show the model from front and rear angles, with the abovementioned pieces and the wing control surfaces alongside. I also removed and reattached the elevators but decided to leave out fighting with the rudders, so they remain in neutral. The engraved detail on the horizontal tailplane was filled in as I didn't think it was particularly accurate; two small access panels were recreated using adhesive tape. A couple of access panels under each wing were also replicated using the same method.

    And finally... two thin, all-encompassing applications of paint... thank goodness! I was beginning to think I'd never get to this point. Now that most sections are painted, I feel a sense of better things to come. Yes, there are still some niggling issues to address and the undercoat will have to be reapplied as and where necessary, but I can now see light at the end of the tunnel. I hope to be able to post more photos in the near future, and hope you continue to enjoy these build instalments.

    Regards,

    Paul
