Revell B-17

B-17, 1/72, Revell, adskilt for genopbygning - først skal alle klardele og andet limes på plads i hver sin kropshalvdel. 

B-17 Testfit eller tørsamling af de to allerede bemalede kropshalvdele. Metaltråd holder delene på plads, mens limning sker med Pin-Flow.

F-84F Monogram 1/48 / B-25J -airfix og Revell 1/72

Revell B-25J


Tørsamling med metaltråd kræver at der bores et antal huller. Det er en ulempe, men til gengæld kan opnås en meget præcis positionering – med lille risiko for at skævheder opstår, mens limen tørrer. Metoden kræver limning med tyndtflydende plastlim, der påføres med Pin-Flow kanylen.

Monogram-sættet af ældre dato er med hævede panellinjer, der er rimelig nemme at slibe ned. Fikseringen med metaltråd og Pin-Flow limning giver god sikkerhed for præcis positionering med lille risiko for skævheder.

Efter anden gang bemaling skete voldsom ”lifting”, da maske-tapen blev fjernet. Årsag: Mangelfuld rengøring før første bemaling. 

Lys-grøn, Humbrol 117, blev påført i for tykt lag. Det har visse steder medført ophobning af ”bræmmer” af maling tæt på modellervoks-afmaskingen. Heldigvis kunne ”bræmmerne” rimelig nemt fjernes med P 600 og 800.

Plesberg Bearcat 1/72


Monogram 1/72 F8F-2 Bearcat
KIT #:PA 144
DECALS:One option
REVIEWER:Nicolai Plesberg
NOTES:1967 release. Falcon vac canopy
With the advent of the F6F Hellcat the Allied air forces in the Pacific were winning the air war against the Japanese air forces, most notably against the once so dreaded Mitsubishi Zero, which so effectively had hacked Allied airpower out of the sky during the first year of the Pacific war. Even so, the growing Allied success was a combination of the Allied planes, namely the aforementioned F6F (not forgetting the F4U Corsair) and the fact that pilots had improved combat experience, while the Japanese still suffered from those crippling defeats at Midway and the Solomon Islands, which cost them their most skilled pilots not to mention their largest carriers. They were never able to recover from these defeats by training new pilots, nor rebuilding its carrier force because it takes time and the Japanese didn’t have the necessary time at this stage of the war.
The Hellcat was, because of its weight (fully loaded the Hellcat weighted more than double of the Zero), not able to turn directly with the Zero in a dogfight, so the Navy put out a request for a carrier based interceptor, which should be capable of outrunning, out climbing and outmanoeuvring anything in service or under design at that time. To achieve this, the Navy was willing to sacrify range and armament.
Grumman’s engineers responded to the request by taking the best feature of the Hellcat, namely by keeping the Pratt & Whitney R-2800 Double Wasp, and then simply design the smallest possible airframe this monster of a fuel thirsty engine would fit into. The main goal was to reduce weight and this was mostly accomplished by reducing fuel capacity the resulting airframe being sleeker, but without compromising the Grumman trademark of rugged construction. The Hellcat´s armament of six .50 cal. machine guns were reduced to four in the new fighter, since it was reasoned to be adequate to destroy the lighter build and less rugged Japanese aircraft, such as the Zero, which fireballed immediately if hit.
The first prototype designated XF8F-1 flew on 21 August 1944, and the first production F8F-1 Bearcat (as the new Grumman fighter was named) in November 1944 and in the following months Bearcats were delivered to squadrons, and training commenced simultaneously. By July 1945 the first squadrons were almost combat ready, but the war ended before any Bearcats had reached the combat zone. The Bearcat served in first line service in the US Navy until 1951-52, when jets finally had surpassed its performance – the Bearcat could climb faster than most early jets, but by 1950 this gap had rapidly been closed.
The Bearcat also attracted foreign service; with the Armée de l’Air in Indochina the French used it in the fighter bomber role and it served with distinction during the battle for Dien Bien Phu in 1954. In service it was known as the “Beercat” because most French personnel did mispronounce its name. Ex- French machines served with the VNAF (South Vietnamese Air Force) until 1959, when these were replaced by Trojans (and later Skyraiders). Also Thailand received more than 100 Bearcats, where they served until around 1960.
The Bearcat has also been used as civilian racing aircraft more or less modified to attain as high a speed as possible. Notably the Conquest 1, Daryl Greenamyer´s Bearcat, set a new world speed record for non-jet aircraft at 482.5 mph (776.3 km/h) in August 1969. A later record pushed this figure up past 520 mph in 1989, but that was achieved in a highly modified and tuned Bearcat named Rare Bear.

This is the old but venerable Monogram kit in 1/72 scale which, considering its age (on my box as well as instructions says 1967) still seems ok. Molded in a dark blue plastic you get 31 parts, including the display stand, and two parts in clear plastic; namely the windscreen and canopy. However, I had bought this kit second hand, so quite a few parts were missing. The prop, prop shaft, two of the four rockets, but most importantly and annoying, too: the canopy! I considered for a time what to do. But then I remembered that Revell had merged with Monogram. So I send an email to Revell asking them, if they where able to help me. They replied willingly, and requested the kit number plus the missing parts numbers.
After sending them the required information and waiting for a few weeks I got the parts minus the canopy! I asked myself how that could be. I had clearly written “Kanzel” (canopy in German) in the email. I came to the conclusion that it might have been the fact that the canopy (and windscreen for that matter) didn’t have a part number; it was apparently some sort of a Monogram trademark from that time not to number the clear parts; I don’t know if Revell has changed that in the mold nowadays. But apparently so much for German efficiency! In the end the problem was solved, as I bought a set of Falcon vac canopies where a canopy for Monograms Bearcat was included and thereby correcting Revell’s spare parts mistake. The decal sheet looked okay despite its age. Some yellowing effect of the carrier film could be detected.
I began construction by cleaning up all the parts, both from flash (not that much) and sprue attachment points as well as in soapy water. The wing pieces, bombs and droptank were glued together as well as the propeller to the shaft. Then I painted the gear legs, inner side of gear doors and engine Silver (Humbrol 11 Acrylic). The cylinders got a touch of burnt metal (Humbrol 53 Acrylic), the seat was glued in place, then I painted the interior plus gear bays green zinc chromate (Model Master 1734). Later I learned it was more or less painted gloss sea blue, but what else should I believe…than the instructions?!
After all this had been followed up (read painted a second time), I glued the instrument panel decal to the left fuselage half with white glue, the black painted stick to the floor and the engine plus tail plane to the left fuselage half also. I dry fitted the right fuselage half to make sure the engine and tail plane did not dry out of alignment. According to the instructions the propeller should have been fitted at this stage by flaring the end of the shaft once through the engine, but I decided to leave it off to ease of painting later. In order to get a tight fit with the engine I painted the propeller shaft a couple of times so it still would revolve and could be left off until the kit was finished.
The next day the main wing got the same treatment by gluing it into the left fuselage half, then after a couple of hours gluing the fuselage together ensuring everything was in flush and securing the fuselage / wing joins with extra glue. After drying and treatment of the fuselage join with filler and sanding I concentrated on the cockpit area by touching up the zinc chromate, scratching a gun sight, painting it Black (Humbrol 33 Acrylic) together with the instrument panel shroud.
Then the, kind of, big thing had arrived, namely the Falcon vac canopy. It was removed from the sheet and by help of a small pair of nail pliers cutting off as much of the redundant material as I dared, then by careful sanding with various grades of sandpaper I had a whole and well fitting canopy to my Bearcat. It was glued in place with Humbrol Gloss Cote. The framing was then painted zinc chromate – twice and then blue (Humbrol 15 Acrylic) twice – together with the outside of gear doors and the drop tank.
At this stage I focused on the cannon barrels (the kit is a F8F-2 all right); the left ones had broken off and the right ones seemed a bit thick, so they were carefully thinned and the left ones cut from stretched sprue, holes drilled and glued in place. After a careful wash with soapy water and cleaning with an antistatic cloth the gear was glued in place and the model went to the paint shop.
Since I had chosen to paint the gear doors with Humbrol 15 Midnight Blue, which I took to be a close match to the gloss sea blue color of the real planes, I then took my tinlet of ’15, but this time the enamel variant. It was an almost perfect coverage with one layer, but wait – the tone of the enamel was considerably lighter than the acrylic variant. WHAT?? That came to me as a surprise. But it must have something to do with differences of the color itself – in different batches of the same color – so nothing new was really the case. Anyway I decided that the acrylic one looked more like the real thing, so two layers of this went on with plenty of drying time between each layer. After a few touch up sessions the markings went on; as the paint was gloss I felt no need to use my Gloss Cote to gloss the surface!
Despite their age the decals went on with no hassles other than there was silvering – a lot of it! Especially the small numbers at the cowling edge were reluctant to stick well to the surface because of the curved shape of the cowling, but when dry I Gloss Coted the decals and around them (not the whole surface of the model was gloss coted; that I deemed unnecessary), I was actually able to eliminate almost all of the silvering. At the same time I marked four spots with the gloss cote on the prop blades for the prop logos, as they seemed prominent on pictures and I was also complementing some other prop planes at the same time. I used some Hamilton Standard logos even though I’m aware the Bearcat had an Aeroproducts prop, but I only had Hamilton Standard and Curtiss Electric logos at my disposal. Anyway I reasoned the Hamilton Standard logos to closely look enough like the Aeroproducts ones to use them. The only things left to do was the marking of the navigation lights, gluing the under wing stores in place and, after securing the propeller logos with Humbrol Matt Cote and pushing the prop in place, the model was finished.

Well it’s a beauty still after 45+ years. Maybe old-fashioned in some areas, but definitely still worth constructing although aftermarket decals would be a good idea. Even though I have the Frog kit in my stash only time will tell how that goes together; the Monogram one went easily together and can be recommended to modelers of all ages and skills.

Problemløsning ved modelbygning

Revell 1/35 Gaz 66 - russisk truck
1) Motor-dele og udstødning er umulige at samle hvis man vil følge byggevejledningen.
2) Panel med gearvælger-håndtag kan ikke monteres i kabinen.
3) Dele til hængsling af førerkabinen mangler forankring.
4) Sæt-konstruktørerne har tilsyneladende opgivet projektet.
5) Detail-dele passer ikke.
6) Sættets ydre dele, førerkabine, chassis, lad, har fin pasning.

Delene limes før bemaling.
Hoveddele bemales efter limning.
Motoren afmaskes før chassis’et males sort.

Herfra skrives normal-tekst.

Ju-87B Airfix 1/24 - et imponerende stort sæt..
Når man normalt bygger 1/72 flymodeller, er 1/24 Ju-87B-sættet fra Airfix  nærmest overvældende.
Arbejdet begynder så småt med at opdele diverse dele, for eksempel til cockpit og motor.

Efter nærmere studier af ætssættet fra Airscale (ovenfor) har jeg opgivet at anvende noget herfra til cockpit-detaljering af Ju-87B fra Airfix. Decals-arket, der omfatter 1/24 instrumenter, kan sikkert anvendes på andre 1/24 flybyggesæt, vel at mærke af mere moderne udgaver, som Airscale-sættet åbenbart er tiltænkt. Hvis ætsdele skulle anvendes til det gamle Ju-87A sæt, vil det kræve en omfattende research, som jeg ikke vil bruge tid på. Instrumentpanel og andet cockpit-indhold må "nøjes" med en noget "nødtørftig" detail-bemaling. Sættet skal altså bygges "ud af boksen". Bedre bliver det ikke. Det gamle decals-ark, der kun giver to bemalingsmuligheder, er af betænkelig dårlig kvalitet. Indtil videre har jeg besluttet, at samtlige decals derfor skal påsættes efter et "bad" i Pledge Future. Det har jeg tidligere haft gode erfaringer med, når det gælder gamle decalsark af tvivlsom kvalitet.
Metaltråd (blød) i stedet for limklemmer
Cockpit-bunden til Ju-87B 1/24 Airfix forsynes med håndtag ved brug af blød metaltråd. De nødvendige borehuller kan placeres et diskret sted og/eller fyldes med termotrukket sprue.

Motordelene fikseres med metaltråd, mens limen tørrer. Limklemmer er vanskelige eller umulige til denne og lignende opgaver.
Når motordelene er fikseret med metaltråd, sker limning med tyndtflydende lim, der påføres med Pin-Flow redskabet. Det er til tider en fordel, at lim ikke skal påføres delene samles.
Hoveddelene blev midlertidig pålimet med hvidlim og herefter bemalet med grå autoprimer og efterfølgende med basisfarven RLM 02. Fremstilling af denne "prototype" giver kendskab til byggeprocessen, så fejltagelser forebygges. Når primer og basisfarven er tør, kan cockpittet adskilles. Næste fase er eventuel montering af ætsdele fra Airscale - og afsluttende detailbemaling før permanent limning finder sted. 

Bemaling med autoprimer pr. spraydåse virker fint - især til større dele.
Silver-bemaling af fly kræver systemarbejde
Den bedst mulige silver-finish kræver flere, for eksempel 10 arbejdsfaser.
Arbejdet sker nemmest ved at følge et planlagt forløb.
Start med at nedskrive alle faser i den forventede rækkefølge.
Filler på vingekrop-samlingen kan være ret vanskelig at nedslibe - især når der anvendes to-komponent Presto polyestersparkel.

Mirage III C 1/48 Academy skal bemales med silver på spraydåse. Processen indledes med filler, nedslibning og primer. Herefter følger silver og Rød Johson. Hensigten er at tydeliggøre manglende filler eller utilstrækkelig nedslibning. Når denne del af nedslibningen er sket, påføres et lag Mr. Surfacer. Overfladebehandlingen afsluttes med nedslibning med 800 og 1200. Modellen får nu igen en silver overalt. Efter tørring påføres endnu et lag Rød Johnson. Enkelte paneler afmaskes og males (med airbrush) med afvigende silver-farver.

ICM Krupp WW2 german truck (1/35)

Min sædvanlige sprue-cutter viste sig ubrugelig til de mindste dele, for eksempel forbindelsesstænger til bremserne. Den uundgåelige vridning, sprue-cutter tangen frembringer, brækker ganske enkelt de små dele. Istedet monterede jeg (desværre for sent) den lille rundsav på min Proxxon-maskine. Med det laveste omdrejningstal på 5.000 omdrejninger/minut kan indløbskanalerne overskæres uden "vrid", så trækstænger og lignende små dele forbliver intakte. Problemet er også, at ICM-sættet er støbt en en lovlig sprød plast.

Undervognen, især bogien med ophæng, til ICM Krupp WW2 german truck (1/35), er noget af et mareridt.
