  1. Sorry to be late responding...I spent the weekend running a state conference....


    The fit was really good overall...there was a bit of seam work here and there due to the modular construction of the fuselage, but nothing that couldn't be handled with time and a little bit of effort. I was originally planning to use the pilot figures in the cockpit...however, they didn't fit very well, so I dropped that idea.

  2. Both are excellent airbrushes, Dick...


    On the Grex, I unscrewed the color cup to change to a different size after cleaning, and without thinking (like I was using a color cup from a siphon feed), I dropped it into a jar of thinner to soak...I didn't notice the seal was missing after going back to it, because it screws in tightly and securely. Almost overlooked the missing seal completely, until I happened to look closely at the other cups...oh, well.

  3. Dick, I've used lacquer thinner to clean both the Grex and the Eclipse...and it caused no problems with either one. During a phone conversation, I specifically asked the Marketing Director of Grex USA about it...and he told me it would be fine to use lacquer thinner to clean their airbrushes. However, you would likely want to removed the seal from the threaded section of the removable color cup if you intend to soak it...the lacquer thinner will dissolve that seal (found out the hard way myself)...the good news is I didn't even notice it was gone until later, as the tolerances are so tight that there was no leakage whatsoever with it missing.

  4. You might also check the air outlet...it's one or two small holes on the front of the airbrush body, beside where the tip seats into the body. If there is blockage there, it would cause your airflow to be spotty. Clean that area, and use a small wire or something similar to be sure tthe opening is clear. Otherwise, I'm with the others...it may be the air supply source, or moisture in the compressor tank.



    At 40 psi, you may be getting blowback at the tip...paint coming out around the tip instead of going through it (a friend had this problem at 35 psi)...that would allow paint to get into the air outlet as I described.

  5. Our chapter has modelers that individually build in almost every genre...armor, aircraft, cars & trucks, sci-fi, figures, ships, dioramas, you name it. There is such a large amount of techniques that potentially cross over between genres,,,,and learning new ones is a lot of fun. That diversity of subjects serves us quite well...and makes for interesting discussions at meetings. The shows I've attended have been just as much fun, and I get to ask questions about the models that are there...
