  1. Adding Memory to Computer?

    I agree 100% More info is needed for an accurate assessment.
  2. Headlights

    There are vacuum pickup tools available for this type of work, but someone recently mentioned to just place a tiny ball of sticky substance at the end of a tootpick. It might have been Playdough. Then use that to pick the lens up and position it in the bucket. I use similar method. I found a roll of adhesive-only 3M tape (basically it is like just Scotch tape's adhesive on a transfer paper, without the clear. I make a small ball of the adhesive and place that on the end of a toothpick.
  3. I have no problems when I swirl the bottle for a while. The airbrushed paint is thin, so it is easy to re-mix the metallic particles back into the liquid. Then, like I mentioned, I blow the "stale" paint out until it comes out properly mixed. But I agree, this would not work with a gravity-fed airbrush and a paint cup.
  4. Adding Memory to Computer?

    I assumed that TJ was telling us that his RAM seems to be only around 50% utilized. If he only uses his Win 7 computer for some simple tasks (like browsing the Web and streaming music) and not for some really fancy CAD apps, or serious video games, then he should be fine with what he has. My thought is that there is no need to upgrade anything unless there is a real need or a reason for it. If his 2Gb is only half utilized, adding another 6Gb will not be very helpful. A defrag is a good idea, but the cooling fan running fast while doing Windows updates is a good sign that Windows updates is the likely culprit. Sunning some sort of cleanup program would also likely improve the performance.
  5. A Thought about the Magazine, etc.

    There are couple of active threads related to your question: Positive one: And a not so positive one:
  6. Two chrome platers left - which do you prefer?

    In my experience with vacuum metalized plastic parts, the process is to first coat the parts with a glossy clear lacquer. Then it goes into the metalizing chamber where a very thin layer of aluminum gets deposited on the glossy clear. That results in a chrome-like silver finish. Sometimes at that point the parts are considered ready, but the metallic finish is rather fragile. So, in most cases there is another clear lacquer coat applied overt the shiny metallic surface. That makes the "chrome' a bit more durable. That final coat can also be tinted with a color dye which gives the final color. It can be any color like gold, red, blue, etc. That is how the colored metallic finishes are produced. And you're right - lots of items can be vacuum metalized not just plastic model parts.
  7. You would probably have a reason to worry is you used water-based paints. But with organic-solvent-based paints (the stinky type), you worry about nothing. This is not a 2-part paint which will harden (by chemical reaction) inside your airbrush. You should be fine leaving it in the airbrush. I use a siphon-fed airbrush with a glass paint bottle on the bottom. When done with one coat I close the needle to stop the paint flow, but blow the air through it (to blow the paint off of the tip). When getting ready for the next coat, I gently swirl the airbrush around for a while to mix the pigment which might have settled down to the bottom of the bottle (not need to do that with clear lacquer). Then I open the needle and spray onto some unwanted surface (like a paper bag), to make sure the paint flows smoothly again, then spray the next coat onto the model.
  8. I have a similar idea, using vinyl gutter downpipe. I will cut the downpipe into pieces long enough to hold the Evergreen bags, then glue then together into something like 2 X 4 or 3 x 3 array of "tubes". I will also need to use a flat piece of plastic (or wood) for the bottom. I bought the downpipe few years ago but haven't found the time to actually work on this low-priority project.
  9. Two chrome platers left - which do you prefer?

    That is not what you want Greg for "chroming" plastic or resin kit parts. I explained that in my earlier post. You need vacuum metalizing equipment. If you want to go the electroplating route, even Micro-Mark (and other companies) sell setups for hobbyists. But not with real chromium (because that plating process requires some really nasty and poisonous chemicals). Chrome plating also requires undercoating of copper, and possibly nickel (to get that smooth mirror-finish). Just like 1:1 metal car parts to.
  10. Adding Memory to Computer?

    That is probably normal. Windows update process can be really hard on the CPU (which will make it run hotter). If you were to bring up the task manager (performance) while the fans are running fast, and show the CPU usage graph, it will likely show high percentage of utilization. Your PC also has a CPU fan (mounted over the CPU heat sink). That could also be clogged up with dust. The power supply (in the rear of the case) could also have another fan which might be partially clogged.
  11. Two chrome platers left - which do you prefer?

    Greg, not too long ago (in another section of the forum) we were discussing this same subject. I'll quote my post there: To get familiarized with the terms and processes, some good info on both plating and metalizing (which is the process we want for plastic model parts) is in: https://en.wikipedia.org/wiki/Plating https://en.wikipedia.org/wiki/Metallizing We don't even know for sure (or do we?) whether either Dale or Kystom Khrome own the vacuum metalizing equipment, or have it done by an outside company. While I have no actual info, I suspect that the cost of the equipment might be a bit much for an individual to acquire, and start a business catering to modelers. If the equipment was cheap and easy to use, why would all of the current companies which offer this service to modelers outsource the metalizing to an outside company?
  12. Adding Memory to Computer?

    Optiplex is a desktop computer - no batteries (well except the little coin cell). What does "acts like it is overheating" exactly mean? As for the number of processes running, that is not unusual, however the longer you own your computer the more cruft (programs and utilities which run in the background, and sometimes spyware) get installed and run in the background, slowing things down. The Windows 7 update process itself has some known bugs where it will hog the computer slowing everything down. If you aren't computer literate, it might be the best to find a local computer geek (hopefully some friend) who could clean it up for you.
  13. Adding Memory to Computer?

    <Old man's voice> Well, I remember when my computer had 256KB of memory. I upgraded it to 1MB, then all the way up to 4MB! </old man's voice> The amount of the memory (RAM) has nothing to do with overheating. The cooling fans and heat sinks are likely plugged up with dust and lint. And if you have lots of programs pegging out the CPU utilization, that will make the CPU produce more heat (as it runs at full clock speed). If cooling is compromised, it will run hot. Depending on what programs you are running, and how many of them are running at the same time, 2 GB maybe be plenty. Especially since only half is being used. If you were constantly running at 80% utilization then I would start worrying about it. Also, where exactly are you getting the statistics? Is your computer is also running slow or is sluggish? The problem might not be low memory. There might be too many programs sucking up the CPU cycles. There are all sorts of cleanup programs available out there. Or a full reinstall of the OS would clean things up.
  14. What Irked You Today?

    I can think of 3 reasons: 1. Laziness 2. Complete cluelessness (not realizing that the quoted post can be edited) 3. Total lack of caring about others who will be reading their post (with lengthy quote), and lack of any sort of logical thinking in general. I suspect that #3 is most common reason.
  15. The Tamiya transparent acrylic paints can be thinned with 90% Isopropyl alcohol to extend their drying time. Alcald II makes transparent colors too. But the paint is very thin (designed for airbrushing) and hot (acetone-based). But since the piece is metalized, it might not attack plastic.
