1/72 Academy TBM / TBF-1 Avenger

Background

Grumman’s famous TBM/TBF Avenger is somewhat a paradox: it’s the largest single-engine aircraft in the war that flew from the smallest of aircraft carriers; designed for torpedo attacks, but dropped more bombs; still in service today, fighting fires and preventing destruction instead of causing it. 

Hello, my name is Leon and I’m from Singapore. This is my first submission to ARC although I’ve been a regular reader for over a year now. Like many, I’ve strayed from the hobby for a good number of years, but am now making a comeback. I hope all of you will enjoy my contribution.   

The Kit

The kit is a 1/72 Avenger TBM/TBF-1C from Academy. I picked the kit from a local hobby shop because a good deal of word going around that Academy is producing marvelous kits nowadays, and of course of its low price (about US $4 here in Singapore).  

There were a few disappointments upon opening the box.The most obvious was the omission of an instrument panel of any sort so some scratch building is in order. The engine was molded with the cowling as a single piece and the detail is very basic. The engine exhaust was solid ellipse-shaped object molded on the fuselage. The wings each lacked the gun port for the single 0.5 MG. Wheel well details are non-existence. The 0.5 and 0.3 cal defense armament should swap size. The clear parts are ok but too thick, the turret framing is missing so masking will require some imagination; the waist observation windows are the wrong bulge types for the British Tarpoons (strangely, Hasegawa has one of those…).

The bug list goes on… But hey, at least its got finely engraved panel lines plus it’s only a $4 1/72. And since this is going to only be a practice kit to hone the ‘lost’ skills, all is forgiven.

It was only later that I found that this kit is one of their earlier releases from the fine prints on the box.

Construction

I’ll try to remember what I’ve done because this project dragged on longer than I liked.  

Construction began in the very basic cockpit. There were a few sinkholes/ejector marks to be filled and sand here, no problem. The missing instrument panel was created by drilling a measured, cut and shaped styrene sheet. Sit belts were made from painted aluminum foil strips with buckles fashioned from tiny triangles from the same aluminum foil. Since this would be a closed canopy Avenger, I decided not to add any more details to the interior. 

The fuselage halves went well together. The only problem came when I tried to attach the engine cowling piece. After much sanding and adjusting, I came to conclusion the two were not meant to be match properly. So I just glued it and moved on, and hope the painting would hide the flaw. The wrong bulged waist windows is replaced with a flat clear styrene. 

The wings were given the gun ports by a 0.8 drill bit. Slightly oversized, but I like it big. The mismatch 0.5 and 0.3 are also scratch built from stretch sprue. The wingtip lights were clear sprue drilled with a 0.3 bit, touched with red and sanded to blend in with the wingtips.

The wings and horizontal stabilizers were glued to the fuselage. Again much sanding/puttying was required due to fitting problems. To protect the rivets detail at the wing roots, the details are masked prior to the sanding. 

The Avenger had a stowed arrester hook which only expose the hook end. This had been omitted from the kit as well. I corrected this by fabricating one with sheet styrene. 

Forwarding to after painting came the attaching of the fine parts. The antennas wires were made from my wife’s hair and glued to the rigging simulated by thin twisted copper wire strands extracted from normal electric cables. The Yaghi radar antennas were enhanced by drilling, and adding small lengths of copper wire strands. Wire strands were also used for brake lines.

Painting, Decals, and Weathering

I brought the US Navy pack from Gunze. The pack contains 3 bottles of thinner based bottles: gloss sea blue, intermediate Blue, Grey Blue. Since the Avenger is to be taking the Tri color scheme, the gloss sea blue (for the top surface) and intermediate blue (vertical surface) are used. The bottom color is matt white with a drop or two of light grey. The cowl ring was matt yellow. 

After spraying the base colors some panels are randomly selected and masked the unmasked surface are given light sprays of various tones of the base colors. This gives a realistic patchwork look that was common to aircrafts operating in the Pacific. The areas to be decaled were given shots of Tamiya Clear to smoothen out the matt roughness. 

The kit decals were super thick and did not go down well, despite heavy coaxing with Gunze’s Mr. Mark softener. Since I have already decided not to invest in any aftermarket product on this kit. The kit decal would have to do. After the decaling, the whole model was given a dull cote of Humbrol. 

The panel lines were given wash made from a mixture of watercolor black/brown and a little washing detergent. This concoction is non-corrosive to underlying paint and easy to remove in case of mistake. Oil stains were done using this brew too and given the finger drag treatment in the direction of airflow. Paint chips were simulated by dry brushing Gunze aqueous silver on the leading edges of the wings, stabilizers and selected panels. It’s easy to overdo the paint chips effect, so I took the advice from the more experienced modelers here in ARC: stop when you feel that its almost done. Gun stains are black pastel brushed on. 

A final matt cote was shot and the tiny bits and antenna wires were added. 

Conclusion

Not the greatest of builds. The project took me about 3 weeks of daily grinding to complete. At the end it was a sigh of relieve more than anything else. Nonetheless I am glade the finish project looked like an Avenger.  

With the practice in this build, next the will be the definitive AM 1/48 Avenger just arrived from Squadron.com
