Strings and Things

At the end of the last update, I had assembled most of the wooden components of the fuselage. Since then, almost all of the rest of the wooden parts have been attached, the whole thing has been stained, and I've added a few coats of polyurethane. I'm now on to an intermediate step of adding many of the rigging strings to the back half of the fuselage before starting to add the various controls and engine parts to the front half.

With that in mind, here are some photos of what I've been up to, along with brief explanations.

Below is an image of the turtleback all assembled. It turns out that it would have probably been a better idea to assemble this off of the main fuselage, and then add it later, as it ended up making some of the rigging a bit harder.

Here is the whole fuselage right after having the turtleback attached and right before staining.

Here are the two control panels. The front one (for the navigator) has a little scratch-built map case. Although it's a little blurry in this image, the knob for the map case door is made from a pin head. I've left the dials and such off, as I wanted to stain and polyurethane the parts first.

Once the stain and polyurethane were on there, I could start gluing on some of the photo-etch metal parts. Here is a close-up of the frame that goes in front of the engine.

Next up was something new to me: printing my own decals. The kit doesn't provide any sort of instrumentation graphics, but rather only comes with the cast metal base parts. I thought this might be a good excuse to try my hand at making decals. I picked up a package of ink-jet-printer decal sheets and a can of decal sealer at my local hobby shop and then spent a few hours scouring the internet for images of old airplane gauges. With some cleanup work in Photoshop, and a bit of experimentation with the printer, I was able to print myself a few sheets of gauges. The sheets below have so many because I wasn't sure how tough the decals would be, and fully expected to ruin a few before getting one to transfer correctly. I also printed one set on a clear sheet and one on a white sheet. It turned out that the decals held up great and the white-backed ones looked good, so I have lots of extra gauges now.

Here you can see a few of the gauge decals in place. Once all was said and done, I think they ended up a bit smaller than I would like, but I had erred on the small side to be sure that they would fit in the tiny embossed ring of the cast metal part.

Here are the two completed control panels in place and with all decals applied.

A few more photo-etched parts in place. The half-circle one is where the pilots step is, used to step up into the plane.

Finally, a sneak preview of the (in progress) next fun-filled step: Rigging the fuselage.

Thanks for tuning in! Hopefully next update will see the fuselage complete and work on the engine beginning.

Fuselage Continues

In the last post, I mentioned that I was not happy with the construction method used in the kit instructions to make the mortised fuselage ribs. The instructions wanted the ribs to be cut from a solid piece and the mortises carved out from those. I made one test piece and found that: a) this is really hard b) the wood that the kit came with for these parts was not the best quality, and tended to flake apart during the carving and c) the final product, because of a and b, was simply not as refined and clean as I would like.

So, what I ended up doing was to get three strips of wood, cut the mortise shape out of two of them, and then sandwich them all together to create a much better looking part. Below you can see what I ended up with, as it is being glued to one half of the fuselage.

Once I got those parts all made, putting together the two sides of the fuselage went pretty quickly. Below you can see the two sides attached to the fuselage building jig, which holds everything straight and square while the cross pieces are glued in.

On the real plane, the top longerons (supposedly a real word) are spliced together behind the cockpit. I'm assuming this is because either a piece of wood that long was tricky to find, or perhaps the front of the plane needed wood of a different type that the tail did. Either way, my whole plane is made of basswood, and it's actually pretty easy to find a 16" long strip of wood, so I don't have to put in a real splice. Instead, the instructions had me wrap a section in thin nylon cord, to give the look of a spliced section.

At the tail of the fuselage, there are a number of additions that are meant to strengthen the structure around the tail skid. For my purposes, this just meant a couple thick strips on the sides and a few steel wires in between the top and bottom.

It was at this point that I found that I am going to need to start skipping sections of the instructions in order to facilitate the stain and polyurethane that I am putting on the model. I need to get as much of the wooden parts together, skip the addition of various metal parts, and still try to leave it all open enough that adding the metal parts later is easy. So, at this point I've skipped adding some of the engine mounting hardware because of the large photo-etch parts that that would require and have, instead, moved on to installing the cockpit flooring. Below you can see my efforts to get the two floors relatively level before fitting all the support beams underneath them.

Finally, here is the fuselage out of the building jig, and with the floor support beams in place. There is still lots of work to be done on the fuselage, but actually only a few more steps before I stain the whole thing and apply the polyurethane.

That's all I've got for now. Stay tuned for more action-packed model-building chronicles!!
