I was trying to do some fairly fine lines for a camo pattern on the skirts of a Stug III I'm working on and I couldn't quite get the results I wanted because to get close enough to get the fine line I was getting too much overspray. Its a single action brush and I was using a Campbell Hausfeld compressor at around 20 P.S. I. Any suggestions?? This was a relatively inexpensive brush around 40 bucks and so far I have been pretty pleased it works great for large to medium areas but w/ fine lines I just can't seem to make them "crisp" Please take into consideration that I am new at this airbrushing thing.

Helloooo anybody outthere??

Try to thin yur paint a little more than usual. Then see if you can get your PSI down in the 10-15 range. If you can get the PSI down, just keep adding a little thinner at a time to your paint and test it to see what kind of line the brush will put down. If you thin gradually, you will find the pefect consistancy for your airbrush, if you go thinner that that you will start to have other problems with your paint job. Just have to experiment with it.

Hi Andrew:

I am by no means an expert with an airbrush, however, I find that lower pressure (I also use a Campbell Hausfeld compressor) works well for me when I am trying to do detail painting like fine camouflage lines. Also, it might help the real experts if you let them know what brand of paint you were using, as well as how thin it was (I have problems with overspray also if the paint is too thin). Finally, the fine lines may be beyond the capabilities of your single action airbrush. It may also help the experts if you identify the brand of airbrush you are using. Hope this helps until someone who really knows airbrushing comes along!

Hi Andrew i have an old Paasche single action airbrush i don't use it anymore i use Iwata's, this airbrush is not normally used to make fine lines or to detail work thats the reason you are having trouble most Paasche single action airbrushes were made to spray a wide to medium pattern, and you can also use thicker paints with it thats its stong points a real workhorse. I think to get a real fine line you will have to mask the area off but that defeats the whole purpose. Check this website out they explain all about airbrushes, and which ones to use for what ever you needs are. go to frequently asked questions.

I had a single action Paasche, probably the same as yours and was able to get tight camo patterns on 1/72 scale kits.
There are a lot of reasons you could be getting overspray and the other giuys touched on several. Another piossibility s a bent needle or cracked tip. Look at these parts under high magnification and replace. The finet the needle, the more likely you are to have damage parts affecting your paint.

Andrew one other thing the Paasche H model if this is what you have can accept 3 different size tips fine medium and large check to see which one you have they are not that expensive i think they are less than $5.00 each, you may not have the fine tip in yours that may also be a problem. Lets us know what happens i am curious. I also agree with Al if the parts are damaged the brush will not work well.

I would also check the needle and tip to be sure both are fine. I can do fine detail with either my Badger single or Paasche duel.

I've only had this a couple of months and I've only used a half dozen times or so. Surely you don't think that its got a damaged tip?? By the way who sells the accessories for Paasche because I can't find them locally?

I don't think its damaged because you said you have already used it and it seems to be working good. The website is below, i also checked the 3 parts for the fine setup in total cost about $11.00, i would check first to see what needle setup you have before you spend any money, also as Al said just to be shore check your parts to see if they are in good condition.
