Turns out giant thin draggy structures don’t hold up that well against multi-vortex tornadoes.

Procured from ebay, this piece of concept art sadly comes without context. It shows a tanker aircraft (pretty much a McDonnell-Douglas YC-15, though the engines appear a bit different… perhaps higher bypass turbofans) topping up an F-15.

Obviously not a lot of blogging of late. A lot of this is due to much of the function of blogging having been transferred over to my Twitter (@UnwantedBlog), but also a lot of it is due to my time having been consumed by the new 3D printer. After some weeks of tinkering with it, I’ve gotten it to reliably produce some things easily, unreliably produce some things with difficulty, and fail to produce some things whatsoever. However, I’ve gotten it to make a lot of a number of different things. So as previously mentioned on Twitter and in the Aerospace Projects Review/Unwanted Blog emails, I’m planning on doing a “crowd funding” project. I’m looking at three levels… $50, $100, $150. Each would come with a package of 3D printed projects, from 1/285 scale “minis” to 1/18 scale aircraft ordnance and nuclear weapons. The top level would also have cast-metal minis in the mix.
I’m working on getting it all together and hope to have it available in the next few days.
1/350 War Rocket, 1/18 Pulse Units, 1/18 Atomic Artillery Shells.
The War Rocket was modified & printed from a file created for Fantastic Plastic. Their version – currently available – is in much larger 1/144 scale. I was impressed with the tiny details that this smaller print picked up, but the wings are mutated. Two have been printed, both with mucked-up wings. Another round of printing is planned with the models standing straight up to see if that fixes the issue; but since that’ll be a *16* *hour* print job, it’s a low priority.
Buttons horned in on the photography. He’s allowed. He’s old, he was unwell last night, he wanted attention, he gets it. He’s at this moment making typing a challenge for me.
The “pulse units” are actually failed Casaba Howitzers. The telescope components failed rather spectacularly. But with some minimal mods, they’ll make great pulse units for the 10-Meter Orion.
The 1/18 Atomic Artillery Shells have printed numerous times fantastically. They’re basically in production, but the rather simple stand I created for the set refuses to print right. Weird.
I’ve printed off two more Fat Man bombs in 1/18. I can see where improvements can be made to the CAD model, but as is they’ll build up into spiffy little pieces.
Right now I’ve got 2 Fat Man, 2 Little Boy hopefully to sell to help defray costs; if there is interest I can clearly print out more. If interested, let me know. I have two of each right now hopefully to sell to help defray costs; if there is interest I can clearly print out more. So… who wants ’em? $60 per Little Boy, $100 per Fat Man, plus postage. If you want both Little Boy and Fat Man… $150 + postage.
If I refine these for a regular production run, there will be some changes for improved printing, some additional details and importantly stands. But “if” is doing a lot of heavy lifting, and the refined production kits will probably run 1.5 to 2 times as much. 3D printed kits provide options that cast resin kits can’t match, such as complete tail units, but they take many hours each to produce.

1/ Second version of the 1/18 Little Boy. Two fit on the printer at once; both came through with flying colors. the thickened tail surfaces worked like a charm; doesn't seem too out of scale. Flash seems to exaggerate surface imperfections. pic.twitter.com/m8nWg1TdAY

I’ve been running the 3D printer, with mixed results. Failures and disappointments are the fault of the CAD models; the printer itself (Anycubic Photon Mono X 6Ks) is working as advertised. Printing is not a fast process; some prints took 12 hours.
Some early results with the 3D printer.
First up: some 1/144 and 1/285 X-20 Dyna Soars. Once I got the angle right, the results are pretty spectacular. The 1/285 ones will definitely be used to make metal castings; probably the same with the 1/144. pic.twitter.com/1O2fBWxy2P

As a lark, I threw in the M61 Vulcan in 1/18 scale, in two orientations. Both seem to have come out looking pretty spiffy, though I haven't trimmed off the supports yet.
Did this just because I wanted to. But if anyone wants one – or more – I can provide. pic.twitter.com/E5NdGp8eCS

The Casaba Howitzer in 1/18 scale. The original CAD model was created solely to create line diagram illustrations and was in no way optimized for 3D printing, thus the telescope shroud printed funny and fell off. Impressed that it did as well as it did. Model needs revision. pic.twitter.com/XIvNrtSdtT

Another one thrown in Just Cuz, a 1/350 North American Aviation Mars Excursion Module. Clearly failed, but again the model was not made for printing. The printer made a valiant effort to reproduce the RCS system, with is on hair-thin struts. Not much point in this at this scale. pic.twitter.com/fq6k2hM11k

1/18 Little Boy, again printed from a non-optimized model. Even so, I'm impressed… the tail was modeled as 3mm thick sheets, and the printer fully replicated that: 0.167 mm thick. Clearly too thin. So currently printing is an updated version. These would make great kits. pic.twitter.com/0D92hWuc0s

Lastly, two shells from a 1/18 Fat Man. The tail struct has the same issue as little Boy, so it'll need to be fixed before printing. Again I think this'd make a great kit. pic.twitter.com/OoxMmuUpHl

This is a little outside the usual for APR, as it is satire rather than actual aerospace design. But I thought it appropriate nonetheless; I remember dreaming up just about the exact same ideas when I was twelve. There was something about the design of those pens that just *screamed* for them to be envisioned as spaceships and missiles and whatnot.

I went ahead and ordered an Anycubic Photon Mono X 6Ks. The reviews are good and the price was ok; I have high hopes that it won’t be a monumental learning curve, but I guess I’ll find out. i expect I’ll be watching a fair number of YouTube tutorials.
The CAD models I’ve made in the past for the likes of Fantastic Plastic will in many cases not translate over directly… something made to be printed at 1/72 scale would have fabulously thin wings, say, at 1/285 scale. So few of the things I’ve already done will be directly usable. But some will. Going to have to go through my catalog-o-stuff for some first test objects. Expect to see some badly mangled Orions…
Financially this was probably not a great idea. So I will doubtless try to come up with something near-term as a way to “crowdfund”a purchase I’ve already made. One thought: my plan was for “standard” metal minis in the area of $25, and a set of 8 slightly smaller minis in the range of $100-$125. So… how about for early funders, $60 gets you one “standard” and one “set,” once I get things dialed in? These items *may* be “mystery items,” or possibly a choice from a very limited preliminary catalog.
Something I *really* want to do: a modification set for the Tamiya 1/350 scale USS Enterprise, CVN-65. This would replace the radar on the island with the original “beehive…” and put the launch shelters/platforms at for and aft for the Pegasus troop transports. *THAT* is the CVN-65 I want next to me 1/350 NCC-1701.
Here are some hypothetical subjects for metal casting as “minis.” I have three pages (standard 8.5X11) of diagrams, all depicting possible subjects at the size they would be at the stated scales. First page shows what I consider a number of interesting designs… not at a constant scale, but size.
Second page depicts a range of Project Orion vehicles again at a roughly constant size. Constant size means, hopefully, a consistent cost.
Third page shows two sets of 8. The US Bomber Projects #1 set has 8 bombers at roughly constant size; US Fighter Projects #1 set has the fighters all at the same scale. 1/285 at least used to be a kind of standard for wargaming, though I’m not sure how widespread it truly was.
Sets like USBP01 would probably all be at about the same price, but those like USFP01 might vary since some designs at quite a bit bigger. What I’m kinda hoping for is the individual minis being about $25 each, while the 8-sets be about $100 each. Thoughts?
These are of course not the full possible catalog, nor would all these here necessarily come to pass. And scales/sizes could vary substantially. A lot of it would depend on actually trying them and see what works, what fails spectacularly.
I’ve achieved a measure of success with getting metal casting up and running. I don’t intend to make too many of these NX-Excelsiors; they’re practice. But I have some spares and can make some more. Anyone interested? Say, $20 plus postage? It is my intention to make some NCC-2000 Excelsiors, and then some NCC-1701-B Enterprises.
BEHOLD WHAT I HAVE CREATED!
I've put the Excelsior into *very* low rate production, mostly just as training. Learned some mold practices that work and some that just don't, but I'm fairly reliably stamping them out. I don't really need a fleet of NX2000s… anybody interested? pic.twitter.com/pOBaSppyGG
