    so here is a link to a quick video I have posted on you-tube. this is the Iwata just running airbrush cleaner at 20PSI to see if this sounds normal ?

    Also at 7 seconds I didn't open the flow any further.

      If your compressor is new, have you tightened things back down now it has been used for a while? I know i was advised by the manufacturer to do so after a while of using it to ensure that everything would be working correctly

        here are a couple of examples of what I'm getting as a result of this "spittling". These where done straight after the video above with my H&S with Ammo green. Running at 20 PSI again and no matter what I do I cant get smooth even coat down, if I open the feed further the "spittling" effect gets worse.

          Sorry for all the posts on this but I'm at a loss and hope the vids and pics help you identify my problem.

          This video is with the H&S at 20 PSI with the Ammo Green just before attempting the spoons

              I'm at a real loss and starting to loose heart a little. This morning I swapped out the 0.2mm Nozzle and Needle combo in the H&S for an unused 0.4mm set never out of the box and attempted some tests on previously primed spoons. I was using Ammo Mig with one drop of thinner to ten paint.

              Spoon on the Left - First Test to try and get a dust coat down at 18 PSI and lightly pulling back on the feed
              Spoon in Middle - Second Test with reduced PSI lightly pulling back on the feed
              Spoon on Right - un-primed attempt to build up several layers - grainy finish

              Going to try other paints now with the 0.4mm setup.

                I've given up on Ammo Mig after having to strip a model because their paint wouldn't dry (after 3 weeks!) but that doesn't seem like enough thinner to me. Are you using their thinner?

                  Yes their thinner and previously I was able to spray these out of the bottle no issues just would have built up in fine layers. The main problem I see at the minute is the speckling effect I am ending up with as a result of this "spittling" noise I get as gradually open the paint feed

                    Sorry this thread is becoming image heavy but only way I can explain what I am getting

                    ok here are some shots from priming more spoons - MIG one shot primer although building in layers from left to right. You can see immediately on the left two spoons the speckling. 1st two done at 22PSI second two reduced to 18PSI

                      Warren.
                      I can sympathise with you. It nearly made me give up ,the shear frustration with trying everything in the book.
                      When you showed the two videos was I right in seeing a gap in the spray at one point and then it cleared and started again.
                      Think you should try to find someone local who can try our your ab's.
                      If they work then it's the compressor on the hose .

                        That's a good idea. Where are you Warren?

                            Ah. I don't think we have any other posters from NI.
                            Is there a branch of Games Workshop near you? Maybe they have a compressor you could try your airbrushes with.

                            Just a thought - I know you tried a new hose, but do you have a quick release adaptor on your hose, and did you change that?

                              Now interestingly before doing the white above I did one Red Tamiya 50/50 same as the white but here u can see I have the expected result and nothing changed when I did the white above but the speckling is back.
