  1. Also, while a single spoke is very thin and fragile, all the spokes combined result in relatively strong wheel.  Just like the 1:1 scale wire wheels. They use thin steel spokes to support the entire car and withstand rough roads, and the forces of cornering.  As for sagging resin, yes some resins have been known to lose integrity in time, but other resins are much more stable.  Once can hope that the wheels (and other 3D parts we buy) are printed using the more stable resin

    Now UV curing CA would be perfect... it would stick to everything and cure immediately.  CA cured with accelerator just is not quite the same as letting it cure naturally. 

    There is such a thing, but UV light cures it similarly to a standard liquid accelerator. Try it.

  3. LOL! Well, AA is not really naughty. It is just a Alcoholic's Anonymous group helping people to quit the addiction.

    We on this side of the pond also have American Automobile Association, and  the acronym is AAA.  🙂

    These simple black decals should be easy to make yourself using some basic graphic editing program and print them on decal paper.

  4. Take a high resolution scan (not just a photo), to have a backup if you need to have them custom printed).  At least 600 dpi, and save the scan using a non-lossy format (like PNG).  To try using the old decals, get some Microscale liquid decal  film and brush paint several  layers over the decal sheet.  That will put a fresh clear film over the cracked old decal film. Of course you will have to trim each decal close to the image before placing them in water.

  5. Next size down from 00-90 is 000-120, then even smaller is 0000-160.  In the past I was able to get mine (in brass) from some sources which evaporated.  Yes, the 0000-160 are very pricey, but if you can find 000-120, they should be less expensive.

    You might also look at metric size fasteners. Those might be available from China for less money (but I cant' give you any specific sizes - not very familiar with them).

  6. Thanks guys.  This is not a project I'm ready to tackle, but it is good to have options.  Silver plating sounds interesting but unlike aluminum, in my experience silver tarnishes, turning dull or even black. I suppose it could be clear coated, but that just adds another layer to the finish.

    As for problems vacuum aluminizing 3D printed parts, there are different printing technologies and materials out there.   If I do decide to send them to Dale, I'll discuss it with him first.

    Pete in an earlier post was considering having the wheels plated. Would this process lead to the spokes looking a bit heavy and defeat the object of their scale appearance due to the build up on each spoke?

    Good question.  I'm talking about the standard vacuum aluminizing process used for decades on model kit's "chrome"parts (not real chromium electroplating). The process where a clear coat is applied to the part, then the shiny aluminum layer is deposited over the clear. The thickness and overall quality of the process can vary.  I have worked with some factory "chromed" parts where no appreciable thickness has been added (Japanese made kits are usually the best).  I have also seen where the clear coat was applied rather heavily.  But the aftermarket vacuum aluminizing ("plating") companies (at this point I think we only have one left in USA) usually do a good job with the process, not adding much thickness to the part's surface.  Not more than a layer of black gloss enamel followed by Alclad II chrome.  I'm still not sure how I'll handle finishing those wheels.

    To the people making the arguement that you can use some lacquers over enamels.

    Not to insult the original post person, but that user is having trouble finding bottles of paint, and it is pretty clear to me they have a very novice understanding of paint in general. So I spoke in absolutes in order to help them avoid possible mistakes.

    As a general rule, you should not apply lacquer paints or clears over enamels. Odds are the lacquer will be to "hot" and react with the enamel. Are there some lacquer products that will work on enamels, sure. But the OP seems to know very little about the topic, so it is best to tell them it won't work, and to test spray first.

    I have included a chart that is a great starting point. As Steve and others have said, there are always exceptions, but in most cases, this chart works.

    A perfect example of an exception to the rule: The chart says acrylics work as a top coat over enamels. However, Tamiya acrylics like lacquer thinners for airbrushing. Thin a Tamiya acrylic with lacquer thinner and it very well might not work over an enamel.

    Another example: The chart says you can't topcoat an acrylic with a lacquer. I topcoat Tamiya acrylics with Mr Hobby lacquer clear all the time and I have never had a problem.

    This is the bane of the modelers.  "Acryilc" is a nebulous term. Acrylic resin is the paint's binder (look it up if unfamiliar https://en.wikipedia.org/wiki/Paint ).  There are acrylic lacquers *AND* enamels, using hot and milder solvents (including water).  Modelers really need to gain better understanding of paint chemistry for successful results (especially if using multiple coats of different types or brands of paints).

    Yes, yes, I know that in modeler's colloquial terms "acrylic" is supposed to mean "water based acrylic-binder enamel". Still, that is not the best way to to approach the subject of compatibility.

    The thing that most people don't understand is there are several different types of lacquer, about a 1/2 dozen, maybe more. 

    Some are hot like the nitrocellulose lacquers that were used on cars and others like the waterborne ones that are relatively neutral. 

    The ones made for hobby use are usually the cooler waterborne types.

    That is the main problem with the hobbyists.  Many just put every paint in the enamel or acrylic buckets, where when in fact are many formulations of each type of paint out there (especially if one starts using paints not made for the hobby market).  Same goes goes for even different brands of paints. When you do that, you are always doing an experiment (on your precious model, if you didn't to a spoon test first).  When  mixing paints and brands you always run a risk of  incompatibility.

  10. I doubt you can save it.  Even ignoring the facts that cured enamel is difficult to remove, and it also likely soaked into the paper, the most problematic is that whatever solvent is used to remove the paint, will almost certainly also start dissolving the ink that was used to print the box.

    But you have nothing to lose by  trying..

  11. Should not dull the chrome paint (you use water, and decal has water-soluble adhesive), but any clear film outside the image will be noticeable. But if you also use decal setting solutions, those might affect the chrome paint's surface.

    Also wondering if the same thing would work for round decals?  Or would they paper just tear?

    That depends on how  precise the fit of the punch and die is.  If they have very close fit then they can punch even very thin materials, but it the fit is too sloppy, then the thin punched material will tear or even stretch.

  13. If someone is willing to spend such an excessive amount of money on one of those models, it is their prerogative to do so. That way the buyer is happy that they got what they wanted, and seller is happy with the profit.  :)  Unless we actually were to ask the buyer "why", we'll never know what drove them to buy it.

    I see this all the time on certain buy/auction sites where people take high quality photos of models like Franklin Mint and Carousel One and ask $1,000+ prices for them.  I don't know who they think they are fooling or maybe they fool enough buyers to make it worth their time.  ?

    If the photos are of the actual model they're selling then nobody's fooling anybody. The buyer knows exactly what they are getting and is willing to spend the (unreasonably high to many) amount of money on the model.  It is worth it for them, and they have the money to spend.

    Our own Paul Hettick regularly sell finished models on eBay which often fetch way more than a thousand dollars.  Those are curbside resin models. No  engine, no opening features.  But they are unique.

    HAHAHAHAHAHA

     

    My orange cap and orange label tamiya cement doesn't smell anything like citrus. What are those people smoking?

     

    Funny or  not, my orange capped hexagonal bottle (Item 87012) doesn't have "LIMONEN" on its label (just "TAMIYA CEMENT"), and it smells like acetone and alcohol.  Is your bottle hexagonal or square? What is the item number (on its label)?

    I'm not here for a peeing contest - I just warned members here to stay away from any citrus-based cements, after it messed up my model.

    Could say the same bout anything with adhesive like BMF etc, just gotta have faith lol.

    No way man! Faith gets humanity in huge trouble (more ways than one).  :)

    Metal foil which is incredibly thin, and retains its shape after forming is nothing like the fuzzy stuff you are using,  I have never seen BMF lift off any surface (including it's backing carrier) all by itself. Sure, BMF can be lifted off if someone applies force to it (like scratching it), but like I mentioned, I worry that your stuff will lift all by itself.  And trying to fix something on the car interior floor is not the easiest job.  Yes, in your example, black carpeting deep in the model's deep and dark foot wells will not be very visible (especially if the floor was painted black to begin with.

    But I'm not trying to discourage you from using it - I just voiced my views on this method of model carpeting, and clearly also stated my reasons.  This is from my life's experience with pressure sensitive adhesive materials.  Others can make up their own mind.

  17. I'm very surprised that a wash would discolor BMF (which is metal foil).  Some modelers actually foil the scripts on the bare plastic  body, then paint the model, then remove the paint over the scripts with lacquer thinner, then polish the exposed foil scripts.

    Sounds  like you probably didn't clean the wash residue well enough from the foil. You should not only be able to clean off the wash residue, then polish the foil to a very bright finish.  To me BMF would be the best and cleanest way to accomplish what you want.

    Tamiya orange cap doesn't have a citrus smell. And doesn't do that. It melts the plastic together and cures just fine. So I don't know if that Limonen is the culprit.

    A Slusher's photo clearly shows, there are multiple glue "flavors" with an orange cap.

    The "limonene" is also clearly stated on the label.  I just warned others about it, even though I have never seen that specific Tamiya cement in any hobby stores in USA.

  19. I originally bought a set from Jack Modeling, but they (while extremely well done, with thin interwoven spokes) are not accurate for for this car.

    I then bought a set from www.motobitz.uk Part# MBA24059.  Those are also well made, and include very well rendered tires (much nicer than the Revell tires).  They also include corrected disk brake/hub spindles for the Revell kit.  My problem is that the wheel and tire are one-piece. I wanted to send the wheels to be "chromed" and with the tire being part of it, that makes things more difficult.

    I'm planning on contacting Jason from Jack Modelling with suggestions on how to modify this wheels to make them accurate for the Jaguar model.  it would be nice to have multiple options available.
