sick airbrush needs a doctor1

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.

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.
Also, you never said what pressure you are spraying at did you?

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.

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?

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! 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?

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.

It was my pleasure helping out where I could. I enjoy talking airbrushes in case you couldn't tell.

Mike

Well you seem to be the expert here and you definitely know what you are talking about! ill see what happends with another compressor and i will certainly get back to you. ill talk to you soon thanks again for the help.
