 Well, we got the fuselage closed up tonight...

 First a piece was made from 1/16" balsa to reach from the firewall all the way to the tail. The proper shape was determined by simply pressing the sheet against the bottom of the fuselage and then tracing the fuselage sides. After cutting the outline it was sanded for a perfect fit all around. Then I marked a centerline across the wing chord and cut a slit in it from front to rear to "relieve" the piece over the wing dihedral area during attachment. In the one close-up photo the slit can just be seen, running between the two red Sharpie dots.
 
 Then it got tricky. I discovered it was going to take about eight hands to hold pressure everywhere that would be necessary during the attachment because of the varying contours from front to rear. I don't have eight hands so I ended up gluing just the front section down first, from across the wing L/E to the firewall. I used 5 minute epoxy, and held it for ten minutes.
 
 Next, I taped off the wing root line on the wing surface and then dribbled CA all down the inside of the fuselage sheet from the wing T/E forward. I taped the wing root off first so that the CA wouldn't ooze into that area as I squeezed the sheet down during attachment. It took all eight fingers and both thumbs.
 
 Finally, I got out the Titebond and attached the rear section. I used Titebond for that step because again I couldn't hold down it everywhere it needed to be at the same time. I could have probably pinned it but it took quite a bit of pressure to get it to lay down well, and I didn't really want to pepper the thing with pinholes either. I ended up pulling it down tight with blue tape, Ace bandage style, working my way from the wing T/E to the tail.

 Boy, that was easy! n~

I use masking tape in place of pins most times.   Can you imagine doing this back when I started, no epoxy, no CA and no Elmers.  It was either Duco, Testors and/or Ambroid.  The model is looking better,

The boys in my hood bought real hollow logs for $1.49, Testors glue for 20 cents and paint for 15 cents a bottle.
The build was about two days.
The useful life might be more or less than the build time.

I had the Scientific ME-109.  Sheet aluminum cowl.  We flew it inside a large shed which was mostly open on the 4 sides.  Made a couple of flights in a day then I don't remember whatever happened to it.

 Made a little more progress over the past couple evenings...

 The Blackhawk kit does provide some clear sheet plastic for making a pair of windscreens, but again I didn't feel that they'd be up to some of the "rigors" this model will likely be subjected to. Looking naked without them though it needed some representation, so I made a couple out of solid balsa. Kinda corny looking but they'll do the job.

 After that was adding a support/brace piece forward of the firewall, between the lower part of the fuselage sides. I thought that would help toughen up the nose a bit more. Those couple of steps now complete the "build" portion of the PT-19 project.

 We're into finishing now. Tonight it got the first two coats of 50/50 Brodak clear. After it dries and it all gets a light sanding I'm going to do some light fillet work in a few areas with Aero-Fil. Once that's all done it will be full bore into the final finishing. ;D

 Doh, I almost forgot to put the tip weight in! :o

 Got that done last night. First I marked and "routed" a recess into the bottom of the wing with the Dremel and a small bit. I did that so the kit supplied tip weight washer would end up fitting more flush to the wing surface when finished. Then I sanded each side of the washer for a better glue grip, filled the recess with 30 minute epoxy, and then set the washer into the wing, "burying" it...

I just spoke to the fellow in Canada who is suppose to make our kits, maybe by Fall.  Question:  If this kit was back in production, would you want one.  We offered it with or without an engine but I do not think that an engine will be included in the new kits.  The list price was $66.00 the kit was all laser cut.  Sowhat do you think?

 Tonight the PT got a good coat of DC540 primer shot on it and then all sanded out. The NAPA DC540 works really well, I shot a good heavy coat over the entire model and was sanding it 20 minutes later with 400, no problem. The plane is all ready to start shooting color on it now. I'm hoping to get the yellow airbrushed on the wings and tail after work tomorrow night. ;D

 Just finished the first bit of color. Yellow never covers well at all so those areas were shot with white first. As soon as the white was done I went right from that to spraying the yellow over it. Next will be masking off those areas and shooting the fuselage with Miami Blue.  ;D

 Jim,

 An airbrush makes a LOT of things easier, especially with smaller projects like this. You also use a LOT less paint overall.
 
 Other than the rattle can primer that was used I've painted this entire model with my cheapo Badger 350 airbrush. I've actually gotten to where about the only time I use my spray detail gun anymore is for very large color areas on bigger planes, and final clear coat work. Even there it kind of depends on the task(s) at hand. On the Nobler/P-40 project that I recently finished I did the entire model with the airbrush except for the final clear. On it I don't think I even used a 1/4th of the paint it would have taken with the detail gun. Another bonus of course is that less paint=less weight.
 
Getting pretty close on the little PT now, paint work is finished and now I just have to wait for the mailman to deliver a bit of vinyl I've had cut for it. Get that stuff put on and then maybe a little clear coat and we'll have her whipped! y1

 Thanks Doc, and everyone. Yeah, a lot more work than necessary going on here but I've been having fun with the "upgrades" and applying some "big plane" techniques and details. I figure there's no reason a 1/2A plane shouldn't be nicely finished too. ;D

 Yesterday the mailman finally brought the last of the vinyl details I've been waiting for, back with finished pics here soon! o2oP

 I've been slacking on the updates here, but I do finally have all of the graphics applied to the PT. y1

 Well planned and laid out graphics make a BIG difference in the final result, no matter the size of the model. After carefully determining desired sizes of all insignias, lettering and numbers etc., here are some tricks that I typically use for accurate placement and alignment of graphics.

 Preparing to add the U.S. Star insignias I figured I wanted them 1/2" back from the wing L/E. The first step then was to add a 1/2" wide strip of tape along the wing L/E to use as a reference and "set" the L/E to T/E spacing. Then I measured out from the fuselage sides and put a small Sharpie mark on the tape where the top center of the star needed to be, duplicating the same measurement and mark for each side, on both the top and bottom of the wings...

 Once all four star insignias are in place they then help create their own reference points for adding the rest of the graphics. y1

 Next was adding the "U.S. ARMY" to the bottom of the wing. First step there was to simply add a piece of fine line masking tape all the way across the wing, from the top of one star insignia to the other. Since we already know that those insignias are properly placed that tape line then becomes the primary reference line that you base everything else off of.
 
 Then, below that line, I added another 1/2" piece of green tape that is simply for use as a spacing and alignment reference for applying the graphic. (These processes are where it's very handy to have a lot of different widths of tape around, and even cutting your own custom "spacing" widths when necessary)
 
 Next I drew reference lines onto the transfer paper of the actual graphic for alignment during application. After that was determining "center" of each graphic, marking it, and then measuring out from the fuselage sides and marking the green tape where I wanted that "center" to be. After that it's simply applying the graphic, aligning that "center" mark while also making sure the horizontal reference lines are properly lined up...

 With graphics you typically get ONE shot at proper application and placement. Taking a little extra time to plan, measure and line things up makes it a lot easier to get it all "right" and makes all the difference in the final result. ;D

 Thanks Doc, but it is still just a basic sheet wing trainer. Paying attention to details while building does make a difference in how the small models perform and appear or "present" too though. Along with trying to offer some tips these are also thoughts and ideas I'm trying to point out or remind people of with this thread.
 
 With the little PT here I've just been having some extra fun, practicing and testing some techniques with the build. Every once in a while I find it fun to take a break from the 'big" models and build a simple, small model. Part of that fun is trying to turn out a nice example of a model that most normally assume is just a "crappy" little plane. That doesn't always have to be the case though, the way I see it the smaller planes deserve a little extra time and a good finish too, it can be just as satisfying as doing the same with a "big" plane. y1

 Anyway, as of a few nights ago the final clear is on, just gotta get a chance now to do the final assembly. ;D
