    This is a small project inspired by a model by one of my favorite artists. This is a low pressure build based on an idea I'd been kicking around for quite some time.

    The design is a modified TOS era Starfleet scout. I've included sensor masts with sensor assembly pods which (when done) should feel a bit like the sensor pod on the tail fin of the space shuttle Columbia.

    The model will be totally scratch... no third party or kit parts will be harmed in the making of this model. It is at 1/500th scale, the same scale as my Phase II Enterprise study model.

    Here are some of the parts I've gotten together so far (with foam core board stand-ins for the dorsal and upper sensor mast)...

    [​IMG]

    Anyways, nothing is glued together yet, everything is basically set (or taped) in place. Mostly I wanted to see how the mast idea would work and play with some ideas before starting in on the construction of the actual parts.

    While the pod assembly was inspired by the space shuttle, the mast itself was inspired by one of the early Voyager concept designs. I liked the idea, but being a TOS era ship it won't be as busy as the Sternbach version.

    I got together a few more parts and worked a bit on the fit of the primary hull pieces. Because the top piece isn't perfectly even on the inner surface, it is easier to use a series of spacers to close the gap between the upper and lower pieces. Oddly, it wasn't nearly as uneven as I was expecting it to be.

    More pics...

    [​IMG]

    I also need to build an internal structure to support the nacelle (which is bending a bit with the large hole for the channel being wide open). I'm still working out how to build that structure as it will support both the nacelle, the primary hull and dorsal and the display mounting point.

    I glued the top and bottom halves of the primary hull together and started in on sanding out the seam. I haven't done any puttying yet, just hit it with a quick primer coat to see where I'm at.

    [​IMG]

    And this is a sketch of the approximate configuration of the Columbia that I'm aiming for...


    Even with the drawings missing a bunch of the details, I think it gives a good feel for how it'll look in the end.

    This is meant mainly as a fun build that should move along pretty quickly. And unlike my 33 inch Enterprise replica, this should show some nice progress (I've made a lot of progress on the Enterprise, but not much that is very visually interesting at this point).

    Looks great so far! (I'm partial to smaller ships like that.)

    I'm glad that version of Voyager was passed over - the under slung engines are cool and all, but the fins make the design too complicated.

    Thanks!

    Yeah, when you consider that the outboard panels on the warp nacelle of the Voyager concept design swept outward during warp, it really just had way too much going on. I'm glad they ended up dialing it back quite a bit for the final design.


    Small update...

    This is another configuration test, again with some foamcore board stand-ins for parts I haven't started yet...

    [​IMG]

    This is pretty much how I envisioned it and even in this rough state I like the overall feel. I'll most likely start in on the dorsal next (as I've done a bunch of those in the past) and I'm pretty close to attaching the bridge/B/C deck structure.

    Looking good, as always! I'm curious what's your plan for a deflector dish? Hang it from a boom Franz Josef style? Leave it off altogether? Something else?

    Can't wait to see more!

    I'll be leaving it off. Jefferies originally had all that equipment under a nose cone on the secondary hull, which was removed to make the ship more interesting looking. I figure that type of functionality would be part of the sensor pods.

    And I like how it looks without the dish.

    I've decided to forgo the nacelle channels. I realized that this is the same detail that I was getting hung up on with the Enterprise, and I was running into the same issue here... which is exactly the type of thing I wanted to avoid with the build (which is supposed to be a fun, low pressure project).

    Here are a few more shots with the start of the dorsal and lower sensor mast. That is a spare nacelle body I am using to get a feel for how everything will be arranged in the end.

    [​IMG]

    I'm about to make the molds for parts for the sensor pods. Once I have those in hand, I'll trim down the ends of the sensor masts to join them.

    I made a little more progress, mostly on the upper sensor mast...

    [​IMG]

    Even without the sensor pods in place, I think it is starting to come together. The upper and lower sensor masts are about half the thickness of the dorsal.

    A bit more work done...

    I spent some more time puttying/sanding the primary hull rim, sharpening up the upper edge and evening out some spots I noticed after my last close inspection of the surface.

    I also put more time into the nacelle, adding the rear box features to the body and started in on sculpting the forward box features (they are just taped in place in the images below). I also cut the holes in the body for the dorsal/lower sensor mast to go through (I made that part as a single piece to make sure they aligned nicely).

    Here are some closer views of the areas I was working on...

    [​IMG]

    One of the other reasons for doing this build (besides the fun of it) is to get a chance to put some of these parts into action and see how they look while I still have the chance to make alteration on my Enterprise study model (based on the 11 foot filming model as a model). And it is nice to take a fresh look at these parts after putting the project on hold about a year ago.

    I need to still make the molds for the sensor pods, but I've been putting it off because it tends to be a messy process.

    I've made some more progress...

    The nacelle dome I'm using is actually made from the same batch of resin I used to make the front end caps of my Phase II Enterprise when I realized I had extra.

    This is a series of test assembly shots as the model stands right now...

    [​IMG]

    I included a mockup shot of my Columbia insignia on a uniform just for the fun of it at the end of that series. Someone had asked about the insignia, I based the shape on the last mission patch of the space shuttle Columbia (though I had also considered basing it on the Columbia's first mission patch).

    [​IMG]

    I thought you guys might like to see the Columbia next to my studio scale Enterprise. The Columbia is using the alignment box that was made for my Phase II Enterprise (because they are the same scale, 1/500) rather than building a new one for it. It shows how much bigger the Enterprise model is (at approximately 1/333 scale) and the contour differences between the primary hulls (the Columbia is based on the 11 foot model's contours).


    I started in on adding the grills to the dorsal. And I wanted to test the graphics for my decals to get a feel for how they would look on the model (so I can make alterations before I print the final decal graphics on the decal sheet).

    [​IMG]

    I've already started modifying the decals a bit based on some suggestions, and I'm debating other alterations mainly based on the limitations of my abilities to print decals (I'd need to have JT Graphics print them if I wanted to incorporate colors close to white in the graphics).


    So... you guys haven't said much. Even though this is a side project, this is a full and completely scratch built model, using no third party or kit parts. And it is a live test of the one-sixth studio scale Enterprise parts to help find short comings while I can still fix them for that scratch built project. And the Enterprise parts are all based on my plans of the 11 foot model, so this is another opportunity to check my research as a physical model.

    The only real difference between this model and the one-sixth studio scale Enterprise is the material I used to make the parts (I'm using TC-1630 for the Columbia where I had used Alumilite White for the Enterprise), but the parts shared between the two projects are from the same molds.

    Any thought or comments?

    Well, all I can say is that the work is lovely. As ever, your technique is clean and downright enviable. I like the markings too, very Trek traditional. If anything, and this is on a purely subjective--my own opinion level--I'm not sure how I feel about the red pennant on the upper sail. It's horizontal stubbiness seems at odds with the vertical nature of the structure. The large area could lend itself to a more graphical approach, as seen on many commercial and even military planes. But, again, just my opinion.

    I look forward to seeing this unfold. It really is an interesting project. I'm perfectly happy to assume this is the ship the TMP comm chatter was talking about.

    Thanks!

    After playing with a number of ideas and suggestions, I'm actually leaning toward a less is more approach (I don't want to move too far away from the look of the tail of the space shuttle Columbia). AdmiralBuck suggested the simple number/name on the masts (which I liked as it feels very naval), so I'll most likely limit the additional hull markings to just those.

    Here is a quick sketch of what I'm planning on currently...


    Did a bit more work on bringing aspects of the dorsal, nacelle and lower mast together. I've also made some pretty good progress on adding the lower sensor pod.

    [​IMG]

    I've also started in on the upper sensor pod, I just didn't take any shots of it.

    The sensor pods are going to be a bit larger than I had originally drawn them, I wanted to make sure I could include some detail on them.

    Another series of test assembly shots, this time including the front of the sensor pods.

    [​IMG]

    The reason for doing the sensor pod domes in copper is to maintain the visual language of the original series. The sensor pods are supposed to serve a similar role to the navigational sensor/deflector assembly on the Enterprise, so I wanted the colors to be similar.

    There are a few spots on the upper and lower sensor masts that need a little more attention, then I'll return to work on the primary hull. I need to catch a few rough spots along the rim, and then I'll finally attach the bridge/B/C deck to the primary hull.

    I love, love, love the fin on the underside of the nacelle. It really makes the FJ scout design pop. But, I have to say that I'm not sure about that upper fin. The ship just looks...unbalanced? Have you considered going with a much smaller fin up top? Lovely model overall, no doubt.

    I had played with a few different sizes, specially as Jefferies had originally included a small fin in that spot in his original design, but for this model I wanted something that felt a bit like the space shuttle Columbia's tail fin, yet with a large enough sensor pod that you could make out some details (even at this small scale).

    I think the other thing that I'm partial to is the fact that it feels a bit like a model of a sail boat.

    I've also been playing with ideas on painting the model so these modifications are a slightly different hull color from the rest of the model... to make it look like these are unique additions to just this one ship and not a standard design for a sub-class. But there is still a ways to go before I get there.



    Okay, so not too much progress, but here is a larger view of the model (still just set/taped together) with some of the design's inspirations included...


    And I finally got a chance to shoot the model in day light (I'd been shooting at night in very low light recently), so hopefully more details are visible in this set...

    A little more progress...

    I've worked on a few additional elements of the model, the biggest being attaching the bridge/B/C deck structure to the primary hull. I've got to iron out a couple spots and then I'll start painting and assembling the model. I still need to make the lower sensor dome (which is on one of my Phase II molds) and finalize the decal graphics (I'm trying to decide if I want to just use the windows from one of my Phase II Enterprise decal sheets).

    At any rate, here is a quick inventory shot of the parts and paints I have on hand for this build...


    Also I figured I'd share some of closer views of the last series of test assembly shots with you guys. Hopefully it shows the level of detail I'm attempting to reach (even if it also shows some of the rough spots too). Anyways, here ya go...

    Thanks!

    Yeah, I need to go back to work on the decal graphics. It really bugged me that I made the first test printing too big (about 105% of what they should have been), so I've been avoiding working on them since then. Because I don't build a lot of models I don't get as much practice in doing decals as I think I should have to do a reliable job each time. So I end up stressing a lot at about this stage of my builds.

    Of course this is part of the reason for doing this model, to practice all these skills. But I tend to get attached to even practice models by the end.

    As a dress rehearsal of many of these elements for my 1/500 scale Enterprise, I'm actually quite happy with how they are coming together. Even if the individual elements look good as masters, the real test is if they play nicely with each other when brought together.

    Thanks again!

    Weird. I had just been sketching a design similar to this, but with half-length nacelles on both upper and lower pylons. I was contemplating a scratch build, but watching your perfection is so discouraging. Lol.

    I really like your design. Something that might be neat, that I just thought of, would be a vertical impulse engine design. Maybe one that went from pylon to pylon over the back of the saucer.

    I'll have to give that a try sometime. In this case, I wanted to see how close to the 11 foot model's impulse housing I could get to cross check my plans. But yeah, this has started me thinking about a number of other variations I'd like to experiment with someday.


    A bit more progress...

    Here she is with a bit more done...


    I've finished applying most of the decals. Once I've made sure that there isn't any silvering I'll apply a few coats of gloss and then a few coats of matte and she'll be done.

    Here is how she looks right now...


    For a 100% scratch built model, I think she turned out pretty nice. I think she could have been better if I hadn't rushed, but she was fun to build!

    Could be better?!?! I suppose there must be little imperfections in person, but from where I sit, it's a pretty damned excellent model! I like the port-side docking hatch on the neck section. Is that just a decal or is it actually modeled as a recessed feature?

    Also I'm glad you went conservative on the markings on the sail. Very convincing design. I'd be happy to load this version of Scout Columbia into my personal head-canon. And I still want to try my hand at building a 1:2500 replica if you don't object.

    Thanks!

    I'd love to see a 1/2500 version! I'll be putting together a more complete set of plans for her, but the main difference from the one I posted is that I made the sensor pods larger (which will also help at 1/2500 scale). The main thing to note is that the sensor masts are about half as thick as the dorsal.

    I look forward to see what you come up with. I'm always impressed with how much detail I've seen people get out of their 1/2500 builds.

    The docking hatch is recessed a small amount, so even if you can't see the decals because of a glare on the surface, the physical circle would still show. The decal for the door is from the Phase II Enterprise decal sheet, but the target ring decal was made for the Columbia. I figured this modification was during the Phase II era.

    I always felt that with the scout/destroyer configuration the dorsal spaces would be mostly devoted to engineering, so the only windows I put on the dorsal were directly across from the docking hatch for the receiving area. Engineers don't need windows.

    Speaking of the Phase II Enterprise, I thought I'd share a few shots of the Columbia with the Enterprise as both are at 1/500 scale...


    I'll inspect the decals on the Columbia today and if they are all good I'll start in on the clear coats. After that, a few small details and I'll start taking beauty shots of her.

    I love how green-grey it looks in these pictures verses how blue-gray it looked in the previous set. Would you mind telling us what paints you used?

    Thanks!

    Yeah, the color pulls more blue when the main (or only, in the case of those test shots) light is ambient light from outside on a sunny day. In does the same thing, only towards yellow brown with some of my lamps at night (or shooting near sunset).

    These are the colors I used...
    • Tamiya Luftwaffe Light Blue (AS5): Base hull color
    • Tamiya Light Ghost Gray (AS26): Accent under front of nacelle
    • Tamiya Medium Sea Gray (AS11): Impulse housing, rear nacelle accents, leading edges of masts and sensor pods
    • Tamiya Light Gray (AS18): Leading edge of dorsal

    For the base color I was looking for the best color that closely matched the best sample color I had on hand... Behr Frozen Pond.

    Luftwaffe Light Blue looked like it would work, but the fact that blue was part of the name made me run some test to be sure. Here are a few test shots of the paint with the Frozen Pond color sample.

    First with normal lighting...
    [​IMG]

    And with the flash (compared to the 33 inch Enterprise under studio lighting)...
    [​IMG]

    And this is on my Phase II Enterprise right after painting her with the color sample resting next to the model...

    I used all the same colors on the Phase II Enterprise, which meant I had all the paint on hand when I started painting the Columbia.

    Another set of pictures... this time I took a few in front of a white background to see how it looked (I had set up the background for my wife's project). Even in low light it is easier to take shots against the white background... but I still like the black better ('cause it is more like space). I also included one quick-n-dirty composite image, hopefully I'll have some time to do more soon.

    I also put together this collection of shots showing how I made the lower primary hull as an example of how I make larger parts...


    I figured this part was one of the better examples of the process I use.

    I'm not sure if I missed it, but is there an internal armature supporting all the pieces together or are these just pinned together and glued?

    Not really... there is a small piece of metal tubing coming down from the primary hull into the dorsal, but it is really more to help with alignment. The dorsal and primary hull parts are pretty rigid (and not very heavy), and I extended out a small structure forward from where the dorsal entered the nacelle that supports the mounting tube (because the body of the nacelle is cardboard).

    If I had made the nacelle body of the same TC-1630 that I used to make the primary hull, this wouldn't have been an issue. Even when laid up pretty thin, the TC-1630 is quite strong and rigid. So I'll most likely be making masters and molds for the nacelle body parts for the Enterprise in the future.



    Okay, a few more composite shots...

    Really pretty. I think your less is more approach is entirely appropriate. After all, who is 'outside' to see the markings anyway? ;^)

    Thanks for sharing your 'turning board' technique. I recall seeing David Merriman demo basically the same technique which he used for his TOS Enterprise build (he made a mold for vacuforming the saucer parts for his project...), longer ago than I care to consider. I've been considering using this method to fabricate some 1/48 scale Saturn V parts (you can use a 'scree' for linear as well as rotational scraping.) Good to see the old skills still in use...

    Yeah, I've used that technique to help build the masters of the secondary hulls of both my 33 inch TOS Enterprise replica and my 1/500 scale Phase II Enterprise...

    [​IMG]

    I had been putting some thought into using the same technique to build a Gemini spacecraft at some point. While slower than a laithe, I actually like the hands on sculpting aspect of this method.
