    G’day Carl, the extraordinary work you are putting in on this build is most impressive. I am doing somewhat of the same thing as my first model but am heading towards a Netherlands East Indies P-36 on Java in early 1942 but with a very steep learning curve I cannot realistically expect to come anywhere close. The boxing I started with has the decals for ‘JOE SOAP’ so as I will not be using them you are welcome to them. I am totally new to this game so if you would like the decal sheet you will need to show me how to trade contact details offline to give me your address and I will send them

    Thanks for the offer John (@wackett). I have a set of decals with "Joe Soap" as well so I wouldn't need yours. But I appreciate the offer.

    As for the learning curve, do what you can and don't worry if you think it doesn't match what someone else does. We all started at the same point and bring different experiences to the hobby. I used to be an aircraft mechanic so I am quite familiar with aircraft in general. That makes building model airplanes easier. Please post what you're doing in this group under your own build thread. I am sure there are people who would love to see your work and there are also many who will provide extra encouragement.

    Gear looks really nice in their new incarnation, Carl (@clipper). I think they will look better than the plastic. Well done with the metal replacements.

    Welcome, John (@wackett), to iModeler. Looking forward to seeing your Dutch P-36. I think you will be surprised how well your P-36 will come out. The only thing needed to improve your skills is the willingness to try new things. YouTube and the Internet is a great source for all of the techniques you will ever need for your models. Cheers.

    I'm gradually making progress on the wings now. I will get back to the landing gear after getting the wings out of the way. I want to have them installed before attempting to do the final fitting (but not installing) of the landing gear because I have to scratch build the gear doors as well. Having the wings where I want them will add in getting the doors to look right.

    I had some fit issues with the resin casting inserts I made, mostly self inflicted, but I am working through correcting them. Mostly gaps, but some steps as well. Fortunately, the steps are in areas where some careful filing can eliminate the problem. I am, however, going to have some surface detail restoration to perform afterwards.

    Because my resin casting inserts could not include the top of the wing portion (due to the way I had to cast them), my plan had been to add the inserts, and then build up the top portion at the leading edge using milliput epoxy putty filed to shape. So the first step was to add it to the wing leading edges. It is by design that the amount added was more than needed. I wanted to leave enough to do the final shaping without having to add more later.

    When I do these sort of things, I tend to get in a bit of a hurry and end up with something less than what I like. So I made sure to take my time on the left wing first. Shaping was carefully using a hobby knife, different shapes of files, sanding sticks and paper, and some scraping with a #10 blade. I switched back and forth between these tools, gradually working my way from the sides at the leading edge, to the bottom and then back up to the top. During the process, I also gradually reduced the amount sticking out forward of the leading edge. I used the Academy wing parts as a general guide for this by comparing it to my shaped part.

    I am going to complete the left side of the wings (including surface detail restoration), before I start on the right hand wing.

    This is impressive scratch build work, Carl @clipper
    The blob does indeed look like to have the correct size and shape, nice idea to create it this way.

    Super job on creating those wing portions, my friend @clipper!

    Thanks John(@johnb) and Spiros (@fiveten). I'm pleased with the way these came out.

    That work was the first of a few things I wanted to do to the wings before gluing them to the fuselage. After working on those leading edge fairings, I had to smooth out the resin inserts and restore the surface detailing. That went pretty well with only a small amount of second round filling required. I rescribed the few panel lines obliterated during sanding and then used a rivet tool to replicate the surface riveting in the same areas. The tool was .55 inch and matched up perfectly with the molded in rivet detail.

    Next thing was the center-line hump on the lower wing. Looking at photos shows this to be open at the back end whereas the kit is molded closed. So I drilled and filed this area to open it up. The center-line hump also has fasteners on its edges which are not included in the molding, so I replicated these using a palm punch set after marking the locations with a pencil.

    So it was time to fit the wing. Probably because of some assembly error on my part, the wing was slightly off at the back lower end. Not very much, just enough that it required me to hold it in position to be straight. I also noticed that the aft end of the left hand wing was a bit low, which would have resulted in a step at the joint if not corrected.

    I spent some time cleaning up various spots and relieving certain areas to get the back end of the wing to mostly lie straight without having to hold it. And to correct the low edge on the left hand wing, I insert a small shim on the inside that pressed up on the wing so that it was raised up to the level of the fuselage wing root.

    Given that I still sort of had to hold the wing straight, I elected to glue only the back end initially. Once it's dry, I will go back and complete gluing the wing to the fuselage.

    Excellent job, my friend @clipper! Looking nice and smooth. Good dealing with the wing to fuselage joints.

    Thanks Spiros (@fiveten) and John (@johnb). I got the seams cleaned up and ready to go. They were fairly clean already, so it only took a small amount of sanding and restoration. The wing root seams were also good, only getting a bit of MrSurfacer 500 and then wiped off.

    The cowling will be soon, but first I need to get the engine built up, so I moved over to that. The kit engine is quite detailed, it's really amazing what they can mold these days. The only thing not included are the spark plug wires (more on that in a moment). The exhaust stubs for the Hawk 75 (fixed gear version) have fairings over them and the kit parts have an extended exhaust tail at the opening. The kit parts are also solid (not drilled out). The RAF Mohawk does not use the fairings and the exhaust tail is shorter. I modified the exhaust by shortening the exhaust tail and then drilling out the exhausts using progressively larger drill bits. The photos show the exhausts after drilling but before I shortened the tails.

    The spark plug wires modification was difficult (that's putting it mildly). Drilling the tiny (.3mm) holes in the ignition harnesses and then gluing .010 inch lead wire into them using CA glue that was not worth beans was enough of a pain that I may not do any more modeling today!

    Engine preparation looks perfect, Carl @clipper
    I fully understand attaching those lead wires tested your nerves.

    Those wires look scary, Carl (@clipper). Better you than me trying to do something like that. All the effort will be worth it in the end.

    Work on the engine is excellent and you rendition of spark plug wires is really supreme, my friend @clipper!

    Thanks John (@johnb), George (@gblair), and Spiros (@fiveten). I really need to throw out my CA glues and buy new ones. And I need a consistent way to hold these small parts still when I am working on them. Half the battle in gluing these wires in place was holding them still long enough for the CA glue to grip. Model builders really need three hands. Two to hold the model and the tools, and a third hand for those times when you need a second tool in the process.

    I have all the base colors applied to the engine parts and will get it assembled today. Then a bit of touch up will be required, no doubt. I've already painted those wires, but I wouldn't be surprised if some of it flakes off when positioning them in the final position.

    Hi Carl (@clipper): You are right about needing 3 hands (or more). Many times I struggle with simply prepping small parts prior to assembly. Holding small parts to clean them up with a sanding stick or Xacto can be a real trial. I try to leave them on the sprue while I do this, but inevitably I have to take them off the sprue to finish the job. Holding on to tiny parts become a real problem which often results in the part flying off into oblivion. I have had pretty good luck recently recovering the parts from the carpet, but frustrating, at best.
