Hi All, I've finally given up with my Badger 200 Airbrush after yet another orange peel job and decided to go for an Iwata one. Can some one help with a bit of advice. I have a very basic Revell starter compressor one of the plastic blue ones with a handle on the top, I think it pushes out about 3 bar. Would this be sufficient to power an Iwata HP- C Plus or an Iwata Hi-Line HP-CH ?
Can any one please tell me the difference between these two Air bushes and which would be most suitable for spraying model Aircraft. I build mainly 1/72 and 1/48 post war aircraft.
Finally will my Badger hose be usable with an Iwata or do I have to buy a bespoke hose and adapter to fit on my compressor.
Thanks in advance.

I may be completely wrong about this, but I would have thought that 3bar is probably a bit too high. I've most often heard of airbrushes being pushed at between 20 and 30 PSI - 3 bar is about 43.5 PSI and might just explain your orange peel effect.

I have my compressor which is coupled to a Badger 200 set to a maximum of 2 bar. If I ever have problems at this pressure, it's usually down to the paint / thinner mix not being correct, paint temperature and ambient room temperature may also play a small part. An orange peel effect, to me, would signify a thick paint mix and too high a pressure and that's for enamels. For Acrylics, 1.5 bar seems adequate.

After first coat sprayed on I use only 10 psi with paint thinners. As for the hose, I think a Badger hose would not fit an Iwata spray gun. 'Well', my badger hose would not fit my new Iwata and the badger is used for first(base) coat only now.

You can get an adapter to go on the bottom of an Iwats (1/8th fitting ) brush to connact to a badger hoze, price is £5.
If your compressor has a fixed output you can buy an inline mac valve (pressure regulator) that also fits of the bottom of the brush, price is £19.

just had a problem with my hose as well , alougth I have a water trap at the compressor end, just as I was happily spraying an alcad finish - SPAT! - a great dallop of water shot through and spoiled the finish. lots of profane language later, It was all smooth again . when testing the hose before resparaying when applying backpressure there are an awful lot of water droplets being shot out. anyone have any ideas as to why this is happening and for a poosible cure?

First thought - and forgive me for stating what may seem obvious - but have you drained the water trap? I ask because if your trap is opaque (and my original water trap is all brass) it may have water in it, which can escape downstream through the hose.
Second thought - if your compressor has a tank, there should be a draincock somewhere on it. If there's water in the base of the tank, it may emerge in quantities that your trap cannot cope with.
