Bubbles and blobs!

Ahhh. That is different then.
Have you ever tried a Sotar 20/20 and compared it with the Micron?

MikeV, I'm a professional artist and use it for more than modelling (although not much). I do some toy prototype painting and figure work, so the super-fine lines of the CM are a real treat. Until now, I've had few troubles- this brush has been great!

Why buy a CM for models?

Glad to see you got it fixed.

congrats!!!

New o-rings and "Super-Lube" - all is well and I'm back up and runnin'. Sweeet!

Thanks for all the help, guys. I got my new parts (o-rings and a needle, lube, etc) and will have the long weekend to get it goin'. I'll keep y'all posted!

How was the brush damaged? Was it a swinging motion? I'm wondering if a bit of the tread to the old tip is still in the brush. Is sounds like the brush has a clog preventing the paint from flowing. A piece of the old thread might be blocking the paint passage.

If all else fails, ship it back to the manufacturers and they should replace it... Iwatat is a good company.

This advice straight from Iwata/Medea- It could be one of four things:
1. The fluid needle head needs to be sealed (either with their Super-lube or a non-drying wax on its threads)
2. Turn the needle clockwise a couple of times to seat it in the head- sometimes they don't mate perfectly.
3. Cracked needle tip. I was warned that machining them down past the flaw only makes them look nice, but they remain non-functional.
4. Bad o-rings. Don't soak the thing in solvent!

Hope this is informative and helpful! Thanks to those who offered help.

No prob with getting it back together- but I've never been able to get the head unit off. I've got it soaking in Mr. Thinner- I'm a bit loathe to use penetrating oil, as that would be a risk to that o ring, as well as a contaminant. Buh!

reassembly ?

Um, my fault: I did replace the tip! I also got a spare needle at the time, so I'm going to try that , too- damn parts are microscopiuc, and I have no microscope! ;) It was suggested at my lhs that the problem might be a bad o ring, but mine seems to check out.

I think a replacement tip is the only solution. You can't expect a broken AB to perform well.
