      Hi fellows, I'm gathering courage to start this one, in LanChile old livery of course. Could you please help/guide me through some questions? I've never tackled anything with resin before, and though many say these kits are easier and faster they are quite intimidating to me.

      1. I have to clean the fuselage of some excess resin and make a long centerline uneveness disappear. How would you tackle it? I have an adequate motor tool and breathing equipment, but I have one go and this fuselage is quite expensive . Maybe saw and then sand the old fashioned way?

      2. The tail seems a bit warped at the top, just leave it in very hot tap water bowl for ____ minutes and start working it with my hands cautiously?

      Any advice will do, as I said this is a one-go with such a kit and it'll calm my nerves a bit if I get to convince myself I've got most things covered before trying for the first time.

      Pd: What is your suggestion for attaching pictures? Photobucket is out of the game it seems.

      To answer your questions...

      For #1) What I do is lay a light layer of Mr. Surfacer 1200 over the area and on either side. Then let that cure and then lightly sand the surface until the lines go away. You could probably get away without the Mr. Surfacer by my worry would be to sand away too much of the resin and create flat spots.

      Because of the resin dust and how soft resin is I avoid using power tools. Generally sand paper/sanding sponge or a file will make quick work of whatever it is you need to do.

      #2) You're on the right track. I've only had to do this a couple times but I've found it doesn't take very long for the resin to warm up enough to bend it back. Just a few seconds (10 or so). I've used two pieces of wood to "press" the resin flight. But be careful not to over do it. Also it does get hot! Someone with more experience doing this may have other ides.

      Also... Make sure you give the resin parts a VERY good clean before trying to paint. The mold release compound will absolutely not allow paint to stick to the surface.

      Hope this helps!!

      I'll second the cleaning. Give all the parts a bath in dish detergent and water, then carefully dry them.

      #1: I like to wet-sand, and use CA as a filler. If there's a small gap, fill it, then wet-sand to the right shape. Rescribing is not a big problem.
      #2: Inspect them all very carefully, and drop them in 70* water for 10 seconds before bending them back. I once did this with an assembled wing, not the brightest idea, but it worked

      Just for clarification, 70 Celsius? Fahrenheit seems a bit cool, but as a tip, it seems an important difference.

      Yes, 70 C. I assumed based on his geography that he'd use those, but it never hurts to disambiguate.

      Hi

      Sounds like a fun project.

      You can attach photos here at Airlinercafe. It's under "My Files"
      Load them from you computer and copy link and paste. Away you go. A lot better than photbucket.

      Cheers

      Thank you very much for the help. Will try for sure sanding the classic way (wet) by hand. For such a ridge this fuselage has I guess I'll try filling with CA for the first time, I am attaching a picture now.
      Thanks for the cleaning and warping tips as well, indeed we use Celsius here, guess hot tap water will do for a few seconds then pressing with two flat surfaces (for the tail).

      Thanks also for the tip on uploading pictures, I had totally missed it somehow.

      This is the raw product...



      And the target:

      I have seen AA 737-200 with clear nose section and most of mine solid resin but
      I did not know AA made a 737-200 Minicraft style nose section.
      Or did you cut it out?
      Not to mention none of my AA kits are that rough and not a single one of them warped!
      ha!

      No Walter, it came like this, seems I got an early release version. Just checked on Kurt's website and indeed the fuselage appears to now come in one piece for the nose with the tail apart, both updates being so much better in my opinion, and yes, looks way more tidy as well. Maybe I could sell it and buy the new version...

      If you are using CA glue as a filler make sure you sand it within 5-10 minutes of applying it otherwise it will set harder than the surrounding resin and you will end up with flat spots and other problems.

      Authentic Airliners haven’t made kits with clear nose sections for several years so you’ve definitely got an old one.

      +1. Or cut it with something. I use dental resin but I've heard of people using baby powder as well.

      ;) hahahahah

      But really... It does work! And you don't have to start sanding immediately!

      Hi Ignacio,

      If you return your 737 fuselage plus the clear cockpit piece to me, IŽll send you 1 of the current production fuselages.

      I agree with Chris: That's top-notch Kurt, really appreciate it. Will send you an email for details.

      And never heard about cutting the CA, maybe Tamiya's gray putty will do...

      I hadn't either until I stumbled upon a video sometime last year about it. CA glue is a wonderful filler (it NEVER shrinks and dries extremely quickly) but it curse almost rock hard. The problem with that is the dried CA is much much harder than the surrounding plastic/resin which makes sanding quite difficult. Cutting it with a powder solves this problem while maintaining the integrity of the CA itself.

      Here is the video I've referenced so you get the idea: https://www.youtube.com/watch?v=a4URAxj6oz0

      I've been able to source some of the dental acrylic referenced in the video and it works AMAZINGLY. But it is very expensive and difficult to obtain in the US because you have to have to be a dental professional. Other countries will probably be different. In any event, Baby powder is said to work very similarly.

      Hope this helps!

      P.S., Kurt really is the best! Absolutely top notch.

      I need to explain something here identifying myself as not being that generous. The reason for my offer to exchange the fuselages is, that I am interested in that single piece fuselage with the clear cockpit section to build it myself.
