    So with my J2M3 build slowly winding down, I decided to start on the A6M2 from my Pearl Harbor box set (A6M2, B5N2, D3A1). I plan on this being a quick, OOB build with little to no additional details added past maybe a few wires in the cockpit.

    Compared to @fiveten and @johnb A6M2 mine looks to have been injected on a Friday. The moulds didn't properly align up, causing the tail to be shifted. Similarly, the cowl was shifted in the same manner. This seems more of an improper setup than poor moulds, but it is not a good sign of Hasegawa's quality control. even the 1980's vintage Tamiya A6M5 I built last year was far better than this. Good thing Eduard is releasing a new A6M2 later this year.

    Moving on to the fuselage, I sanded it to remove the misalignment with 600 grit Infini sanding stick. The panel lines will have to be re-scribed, which is probably a plus as they were wobbly and net well defined (perhaps a result of how the part was ejected from the mould?). I did the same for the cowling, removing the raised panels and sanding smooth the air intake (there was a panel line created from the mould misalignment there as well). I thinned the cowl flaps on one side with a combination of a scraper, knife and sandpaper. I think the result looks better , you can actually see inside the cowl from behind when it is installed on the fuselage.

    The weakest feature of this kit is the fact that the oil cooler is a separate piece from the wing, and that the attachment is right through the landing gear. Again, this part suffered from bad moulding. I dry fit it and glued it in place, with the lower wing leading edge (the front of the oil cooler piece ) needing to be sanded down to fir the main wing. I think this was better/easier to do then have a gap in the landing gear bay.

    I drilled the holes for the aileron mass balances and the drop tank (the latter to 1.2 mm, not 0.8mm, to fit the drop tank), and removed the aileron trim tab control rods from the lower wing. The fit of the wings to the fuselage leaves the wings higher than the wing roots and the front lower fuselage (that nasty oil cooler piece) about 1mm too far aft and 1mm too low of the fuselage firewall. I considered moving the wing forward to make the firewall flush, but that would leave a gap at the rear of the wing/fuselage mating area (easy fix) and a misalignment of the inner leading edge area (harder fix). with the cowl on, the firewall misalignment is not visible, so I think that is the route to go (and shim the lower firewall/oil cooler piece).

    As for the upper wings being higher then the wing root, I will use @lgardner method of gluing the upper wings to the fuselage and then glue the lower wings on. I'm still not sure why the upper wings are so high, unless the lower wing needs to be dropped down (but that would leave a gap at the leading edge).

    Anyways, what a mess. I either messed up the oil cooler alignment or this kit is worse than I thought. So much for a quick build.

    Great to see another Zero being started, Woody @wkubacki
    Looking forward to see yours progressing although yours seem to be a 'close to the weekend' mold.
    With your expertise I'm sure it will still result into a fantastic looking Zero.
    Will be following this one with lots of interest.

    This should be a fun build, Woody (@wkubacki). I also am looking forward to following along with your build.

    Great to see your entry to our ever growing EoJ GB, my friend @wkubacki!
    Your superb skills will produce yet another masterpiece. Yep, quality control issues may take place even at Hasegawa factory...
    Looking forward to your progress!

    Finished the cockpit save for some weathering and making seatbelts. Its fairly simple compared to the Tamiya new tool kits, but as this is supposed to be a fast build I'm not too worried. I did add a few wires to spruce it up, but I doubt much will be seen once it's all closed up. Not pictured is the IP that I painted and then applied the kit decals to.

    I'm still having issues with the oil cooler/wing/fuselage join, so I grabbed a lower wing and oil cooler from a A6M2-N kit and did some dry fitting. I think the best way to go forward is to glue the the wing to the fuselage and then glue the oil cooler on to get the best alignment of the cooler to the fuselage. When i glued the oil cooler to the wing first, it skewed the cooler nose down compared to the fuselage (despite the cooler and wing fitting very well to each other). I'll take some photos tonight to better illustrate this.

    Then I got to thinking, do the A6M3 suffer from this issue too, since they have the same seperate oil cooler? I am happy to say that no, the A6M3 type 22 is a far better fit.

    You are doing some fantastic work here, and it's looking great ! I know exactly what you are talking about with the odd way the oil coolers are installed on these Hasegawa A6M's. To my knowledge each of the different Zero kits use this method. Some fit better than others. I just went through the same thing with my prototype A6M-1 Shi kit. Luckily for me, it went smoothly.

    I'll be looking forward to seeing your next installment. Your Raiden turned out magnificently.

    Beautiful cockpit, Woody @wkubacki
    On my Zero I also mounted the wings at first, prior to the cooler.

    I've been working off and on on the Zero the past couple of weeks, mostly on cleaning up the seams on the gun troughs and fuselage. I made some seat belts, which are a decent copy of the real thing, but I do need to get a set of Eduard IJA and IJN belts. I also drilled out the landing gear doors, the upper deck handholds above the instrument panel and thinned the panel above the IP, and drilled out the exhaust.

    Amazing details added, Woody @wkubacki
    To me those seatbelts look great, no PE required.

    These seat belts look incredible ! You my friend have some serious modeling skills... 🙂 I would not attempt making a seat harness like that even in 1/32 scale. I also have noted your other upgrades as well. I have several of these Hasegawa kits under construction at various stages, and right now is the perfect opportunity to use your ideas. Thank you for these wonderful tips !

    I eagerly await your next installment.

    Sluggish progress on this build, mainly due to the poor fit of the Oil cooler and me cutting off some locating tabs on the fuselage that keep the fuselage at the proper height relative to the wings. After many rounds of sanding and filling I have smoothed over the step at the firewall. I primed the Zero last night with Mr Surfacer 1500, but noticed a few spots that need some minor attention as well as two sink marks on the bottom of the wing. These will be hopefully fixed tonight and the plane will finally be ready for paint.

    This is incredible craftsmanship here. You have done a splendid job with the joints and they have disappeared.
