                        Rich,

                        It's hard to say but diaphragm compressors get hot easily and sometimes have problems.
                        I wish you lived closer as I have three compressors here that we could try out. Wink [;)]

                        It was my pleasure helping out where I could. I enjoy talking airbrushes in case you couldn't tell. Big Smile [:D]

                        Im starting to think you might be right ill see about another compressor im sure one of my neighbors has one. What would cause it to go bad all of a sudden especially when it does not get used all that often?Besides i think we have exhausted all other avenues with the brush itself i have taken it apart and put it back together now 12 times. Im starting to think its not the brush. Ill get back to you sometime tomarrow with the verdict. I cant thank you enough for your time and patience, Thank you so much!Big Smile [:D]Cool [8D]Bow [bow] It never pulsated before that i can remember but there have been times that i have had it wide open when shutting it down, but when i turned it back on not remembering it was wide open it struggled hard to run until i released the valve could this be the cause?Black Eye [B)]Dead [xx(]Question [?]

                        Rich,

                        Is this the first time it has ever pulsed air like this?
                        I am wondering if your compressor is the culprit now.
                        The diaphragm compressors like the Paasche D500 will pulsate when new so if it is getting old it may not be putting out enough air pressure.
                        Is there another compressor that you can borrow to see if that is the problem?

                        Mike

                        Its funny you should mention the cap i was just thinking that for another problem in this forum how funny. There is no preasure guage on my compressor so i really dont know. I have never strained my paint thats a cool idea but it pulses when i run water and straight thinner (or a mix of both) so thats not it. I am useing a compressor made by paasche specificly for this airbrush im at a loss i dont know what started this and its hindering my progress on another aircraft im starting to pull my hair out.Angry [:(!]Disapprove [V]Banged Head [banghead]

                        Rich,

                        Did you strain your paint first?
                        I am wondering if clumps are causing this.
                        Try 3 parts Model Master enamel to 2 parts thinner and strain it through a piece of women's nylons to remove any particles.
                        This may sound dumb but it has happend more than once, you do have the aircap cover off of the airbrush correct?
                        Since they have a hole in them I have seen people leave them on when airbrushing not knowing that you have to remove them. Wink [;)]
                        Also, you never said what pressure you are spraying at did you?

                        It sprays better but only because it has a steadier pulse it would coat better but it still pulses i would be takeing a chance by useing it.Banged Head [banghead]Confused [%-)]Grumpy [|(]

                        The reason I ask is because the #1 tip and needle can be picky about what paints will go through them reliably. The #3 would be a better choice.

                        Rich,

                        A couple more questions:

                        What tip and needle are you using?
                        Is it the #1 (fine) set?
                        Do you have a #3 (med) set that you could try instead?

                        It started out as spitting (leaveing bumps on the aircrafts paintjob) thats what prompted me to clean the brush in the first place i usually keep it like new as far as cleaning goes the brush is treated like royalty. After i broke it down and cleaned it more thorouhly it started sputtering sort of a spraaaaaaaaay spray spraaaaaaaaaaay if that makes any sence there is a break in the strem of liquid that passes through the brush that isnt there when it just sprays air.

                        So with just air coming out, the airstream is steady with no sputtering, but with any liquid it sputters as it exits the airbrush correct?
                        You described it as "spitting" in one post and "sputtering" in another, so I am wondering if you mean it just skips the line you are shooting, or that it spits bigger particles out onto the surface?

                        I am beginning to think it is the packing nut or washer which is parts #8 and 9 in the diagram below.


                        On page 3 of this link it tells you how to tighten the packing nut in step "F"

                        Remove the head of the airbrush and shoot air through it and see if it sputters.

                        It starts to spray for a split second when you pull back the trigger then sputters, ill check to see if it does it without pulling back just pushing down please hold.

                        Richard,

                        Does the air coming out sputter without pulling the trigger back, or is it just the medium that's coming out of the airbrush that sputters?

                        thanks Mike... I am learning a lot about airbrushes just through everyone's daily problems/questions, and your answers! I can't help you harbormaster, if it were an Aztec I know what to do (torque that tip down tighter) but being new to 'other' airbrushes I wouldn't know.. that's why we have people like Mike around!!!

                        Glad I could be of help.

                        Concerning the sputtering:
                        Are you using a glass or plastic jar? Did you check the hole in the cap of the bottle you are using?
                        If you press the trigger down without pulling it back, does the air pulsate?

                        Let's see if we can hopefully narrow it down. Wink [;)]

                        Pull the trigger back out, then remove the handle of the airbrush.
                        On the back of the airbrush, rotate the piece # 20 in the diagram below and get that little tab to stick back up through the slot in the top of the airbrush where the trigger goes.


                        Once you have that tab sticking back up there again, pull that tab back (it is spring loaded) and hold it back while you insert the trigger back down into the opening in the air valve that it sits in. It is a little difficult to do since the trigger pivots and I never liked that feature of the VL. Use a bright light so that you can see in there.

                        I'm also wondering if chunks of dried & broken air valve rubber got blown up into the body. You said it doesn't stop which I'm probably not imagining accurately, so I'm making another guess.

                        New needle was put in before the second cleaning so no the problem was not solved, Mike, that sounds like my problem how do i fix it? Remember fellas the brush shot water and thinner perfectly after both cleanings and i used different bottles too why did it have a problem with paint mixed 2 parts thinner 1 part paint this makes no sence. It was spraying paint like it had no preasure even when i had it cranked.Plus it was spraying in intervals (sputtering) I was useing model master paint like always!Banged Head [banghead]Banged Head [banghead]Banged Head [banghead]

                        Regarding the trigger problem, did you pull the rocker back before inserting the trigger into the airvalve? If that rocker gets out of its slot and down into the airbrush at all it will bind and cause problems like you are having.
                        I think that might be your problem....I think. Wink [;)]
