discussion Another A/B problem Sorted

[Gern]

Hi guys. Back to pester you again.

I tried to do a bit of painting this morning but got very little paint from my A/B (H&S Ultra, 0.4mm needle set up, Tamiya paint thinned with MLT at around 20psi). Stripped the brush and found LOTS of residue paint from the last time it was used - I'll be having WORDS with grandson PJ later as he was the last to use it!

Got it all cleaned up and now the paint is flowing OK. Problem is I'm getting drops of paint on the top horn of my pinch tip which eventually fall off. Any ideas what's causing it? I've checked my needle and the pinch tip and I see no damage, and the spray pattern looks straight and central.

I had exactly the same issue with an Ultra 2024. Contacted H&S who acknowledged a few users had the same experience and they were working to develop a solution, they advised to buy their fineline tip and round cap which I did. Problem solved for me and easy to remove cap and spray and/or clean tip dry. HTH.

That's the one I'm using.

Could it possibly be the needle isn't sitting tight enough in the nozzle and excess paint is flowing past and gathering on the pinch tip ? I've had this before and ended up pushing the needle gently against the tip whilst screwing the locking screw up to hold it, making sure the needle is fully seated against the tip.
(hope that makes sense)

Sorted, but thanks for the suggestions guys. Turns out my nozzle has split allowing paint to bypass it and run along the inside of the pinch tip. Just got to check if I've got a 0.4mm setup or 0.45mm.

Got to ask a question from the guys using the very expensive Air Brushes, are you using the Air Brush to do paintings similar to "The Ceiling of the Sistine Chapel", or are you just using it as a one colour spray at a time, like just agricultural spraying ?

I tend to use mine for various types of painting, mainly single colour usage but I'll also use it for 'shading / tonal' and other variations on the single colours I've previously laid down.

I've had numerous types, from H&S , had no end of trouble before they actually marked the needle and tips. Then had a cheaper Neo and recently one from Ultimate.
Main use primer, top coat, and shading

I have always used Iwata Airbrushes, mostly used for primer, base coat and varnishing.
Recently bought a GSI Creos/Procon Boy/Mr Hobby PS289 with a 0.2mm needle for some finer detail work.

My hands are far too shaky for brush painting and I enjoy using airbrushes.

You should find a lot of similarities, since Iwata & Creos airbrushes are almost certainly made by the same Japanese factory and have some interchangeable parts.

I once asked a top guy at Iwata if the rumours were true and his reply was "I can neither confirm nor deny ".

Sounds like a yes to me
