TreehuggerA trick to try help smoothen out the stepped resin parts, is to mix a drop of water into a bit of Vallejo putty to liquify the putty. This creates a more friendly filling mass that can be help fill the tiny cavities. Best to not thin the putty too much or the filling power goes away.

Desert MarlinI ordered it and it showed up! The guys at Air Graphic sent one!
20 December 2023, 16:38
Desert MarlinOkay, the issue is that the Air Graphic bay is about 3/4 cm short. At least according to the bay doors molded into the fuselage. Looks like my options are to request a stretched bay, modify the bay, or cut the fuselage doors short and blend the remainder...
Thoughts anyone?

Spanjaardasking for a correct set seems a good idea, if they say no, or say that their set is correct and your model not.... then maybe sand the doors and scribe new of the size of the piece you want to fit? (I hate rescribing....)
20 December 2023, 19:50
Desert MarlinI'm leaning toward that solution. I need to obtain the torpedoes (5 ea) and they need to fit in length. I am building the kit wheels up, bay open with weapons deployment in progress.
20 December 2023, 19:58
Desert MarlinTough choice between moving off of the aft panel lines or moving off of the wing fillet on the forward end of the bay. I guess this is what I need to do. The only hope is that the Mk. 44 or Mk. 54 Torpedoes will fit appropriately.

DerMattesI would like Air Graphic to sell the STL files for self-printing the parts. I bought the MW 1 for the Tornado and was not happy with the printing quality, seemed like there were printign issues. Would be interesting to know if they send you a replacement part in the correct size.
Also watching your build of this big bird with interest, keep the pictures coming! 👍 🙂

Desert MarlinCockpit is pretty much done. Would like to find some figures to put in the seats...
30 December 2023, 04:07
Mr JamesLots of lovely detail going into this and very well documented too... Great work 🙂
31 December 2023, 04:17
Desert MarlinWelp… I now have to switch my focus to the bomb bay… there is a ton of work to accomplish there. First, I have to figure out where each of the broken door control arms go so that the doors attach correctly. Let the real fun begin!
31 December 2023, 17:52
Desert MarlinI chose to join the fuselage halves before installing the cockpit so that all the sanding and shaping can be completed. The interior of the fuselage windows can be cleaned until the bomb bay and wings are attached.
31 December 2023, 17:57
Desert MarlinIt appears I will need to shorten the length of the fuselage in order to have the bomb bay work within the panel lines of the actual aircraft. The alignment of the aft end of the bomb bay is very close to the square panel on the bottom of the fuselage and the front of the bomb bay is essentially butted up against the wing filets. Miserable conditions...

Desert MarlinSadly, the BPK kit fuselage is 21.85" long which is spot on with the dimensions given by NavAir...
2 January, 00:22
Desert MarlinDepends. If Air Graphic is correct, then the details and sonobouy ports are 10 mm too far back. If BPK is correct, then the Air Graphic bay is 10 mm too short. The Mk 54 torpedo will fit in the bay but I am not sure the residual length is correct. There probably needs to be a compromise between the two. Since I've already joined fwd and aft fuselage halves, shortening the aft fuselage is not a very good option but could be done… ahhh, new product growing pains…
2 January, 16:41
Desert MarlinWell, it's time to modify the bomb bay. I am using an extended length of 6.25 mm to compromise between the BPK panel lines and the door lengths. Also, the armatures inside the bomb bay will probably belie the modification. This adaption will require the use of the doors cut from the BPK kit since the 3D printed doors are kinda mated to the original door armatures. I will probably sand everything down to meet the needs of the doors since that is going to be the most visible portion of the modifications. Sad that Air-Graphic will not re-print with an adjusted (scaled) length. 5 mm is the least I could add. 8 mm is the full difference from the BPK dimensions. This is the price (and joy) of doing one of these...

Shar DipreeHello Marlin.
The discrepancy in length is annoying.
Wikipedia gives a length of 2.715m (german Wiki) / 2,72m (engl. Wiki) for the MK54. That would be 3.77cm in 1:72.
Maybe there are pictures somewhere where you can estimate how much space the torpedo has in the bay at the front and back.
Or maybe you can even find size information for the P-8 bay?
5 January, 23:59
Desert MarlinI did that very calculation. Came up with the same. I have accepted that the hard points are going to be about 5% to 10% forward of a neutral position. The centering of the Mk 54 torpedos with the HAAWC modification can be fudged to make the whole thing look a little more accurate. it's probably a nudge on the residual space anyway. I have to further modify the bay to build up the structure and the sides of the bay for the additional length. It's going pretty well so I guess I can't complain...
6 January, 00:46
Desert MarlinThe modification to the bay is almost complete. Once the orientation of the bay in the fuselage is set, I can start cutting the doors open. Then I get to figure out what to do with the doors that are now too short...
6 January, 08:13
Desert MarlinHere's hoping ResKit will be successful in sending me their Mk 54 torpedoes. Kinda need those! But, I think there is a war going on… pray for those guys!

TreehuggerRe. photo #16, I tried to drill into 3d printed resin, but it only went well when the drill bit was small, as the drill bit got larger, the drill bit started to chip the resin in places. I used a hand drill, I could have used an electrical one and presumably it might perhaps had not chipped for me, or who knows. I prefer hand drilling, as it sort of gives me more control.
10 January, 07:44
Desert Marlin@Treehugger, absolutely true. It was an extremely slow and manual process. The actuator rod on the inside was used to support the resin as I drilled through. The back wall is actually cracked in about five places just from handling. Mostly applied medium and thin CA to fill cracks and strengthen the wall. Adding primer and paint will add some strength as well. No power tools were used. Chipping is filled with medium CA. Hope it all looks okay!
10 January, 17:19
Desert MarlinLooks like the fuselage around the bomb bay opening needs to be thinned to about 1/4 mm (1/64 in) to allow for the bay door armatures to reach the actuator shaft on the side of the bay... the fun never ends!
11 January, 03:23
Desert MarlinThese Torpedoes are really small. Or my eyes are getting really old...
15 January, 01:56
Jennifer FranklinWish I had seen this sooner; love all the documentation following 👀
23 January, 05:33
Desert MarlinSo, the doors at a bit of work. I need to extend the forward and trailing edges about 1.5mm on each end to make up for the additional length of the bay. The doors look pretty good as is. Just need to make it a bit more accurate.
25 February, 20:43
Desert MarlinThe 3-D printed doors just have too much detail that is somewhat compressed so the goal is to give them the appearance of appropriate size…
25 February, 21:17
Desert MarlinThe bay doors are now corrected for length. Not a bad option. The control arms on the doors are not going to reach the control rod in the bay correctly. I needed to thin the fuselage skin much further than I did. However, the torpedoes in the bay will probably hide most of this sin...
6 March, 09:27
Desert MarlinThe HAAWCs are almost done. I have to add the remaining straps to the stowed weapons. Still waiting on an aqueous paint FS36495 to mix with the FS36622 to make my "Boeing Gray".
12 March, 06:02
Desert MarlinGot the main coat on, mounted the bay doors, started some weathering. Trying to decide which VP to use.
24 March, 04:49
RandoThe Tigers are cool. I like the look of VP-9 and especially VP-10 with the "Big Dipper" logo. Wish it was easier to find a higher resolution image of the instructions (I assume this is the Furball sheet)
25 March, 22:36
Desert MarlinI'm guessing the aircraft that made the pipeline run didn't have a very elaborate tail marking...
25 March, 23:59
Desert MarlinI could be wrong, but I think the VX-1 squadron is a Test & Eval squadron...
26 March, 00:07
RandoAhh I see what you're trying to make. Love that paint job and the look of the torpedo bay 👍
26 March, 01:01
CuajeteI agree with Rando 👌
Desert Marlin, I like the VP-9, VP-16, VP-30 and VP-46, but the one who is going to observe the model daily is you 😉
26 March, 19:11
Desert MarlinI suspect more than myself will see it. But I like VP-42 the best. Mostly because that's the squadron my uncle was in and piloted the SP-5A(B) Marlins. Perhaps that bears some relationship to my online name...
26 March, 20:49
Desert MarlinSadly, I do not believe VP-42 flys the P-8. Or if it is even active today.
26 March, 20:54
Desert MarlinAdding gloss coat today. Looks like it will get a couple of days to dry and cure before the markings arrive.
28 March, 17:21
Desert MarlinGlosscoat looking good so far! As soon as the Furball gets here, I can start applying the markings!!!
29 March, 00:27
Desert MarlinThanks Michael and Cuajete! I need a little more glossy finish before markings!
29 March, 21:07
Jos JansenBecause I only set 1:48, I don't get to see the 1:72 builds...wow, this is a beauty, nice build so far.
30 March, 19:17
Thomas Bischoffgreat job! Followed this build for quite some time and love how it is developping 👍
30 March, 19:22
Desert MarlinIt is taking much longer than I anticipated! I think the torpedoes and the bomb bay are way more work than planned. Now a stand is needed and I'm not sure how that is going to work yet…
30 March, 21:20
RandoVP-16 looks like a great choice 👍 I got 1/48 Moose Republic Draken and 1/72 DXM F-4 decals coming now
4 April, 04:03
Desert MarlinI got the base finished for cradling it at shows! Pictures after markings are on!
4 April, 18:15
Michael KohlBig and good don't go together often. Here they do. Fine modelling we see here.
11 April, 08:19
Desert MarlinThank you all!
@Michael Kohl - Yes, annoyingly big. Don't know how many times I thought it would break hitting the work lamps...
@Rando - the base was its own project. Thanks!
@David Taylor - The Aussie and Brit decals are in the box.
Thanks again everyone! It took about three times longer than I originally expected!
11 April, 16:25
Desert MarlinThe entryway hatch decals need to be cut in quarters before being applied to the doors. Their shape is a bit too exaggerated for the actual shape of the doors. The overwing hatch door decals are perfect. The observation window decals were also perfect and did not interfere with the window masks!
11 April, 16:38
Desert MarlinThe pilots sit too high in the cockpit. More work to lower the seats would help.
