Airbrush - Which needle size?

[Noel]

Question:

 

Which airbrush needle size should I use for detail such as weathering, and which for re-spraying larger areas such as a coach or loco?

 

It came with 0.2, 0.3 and 0.5mm needles and nozzle pair. so far I have only used the 0.2mm. I'm not sure for which applications I should use the other needle sizes?

 

Thanks in anticipation

Just make sure the nozzle, needle and nozzle cap are all from the same size range. Don't mix and match 0.2mm needle with 0.5mm nozzle and 0.3mm nozzle cap. A blunderbuss you'll be holding, not an airbrush

Thanks Richie. Is 0.5mm more suitable for say coach sides and coach roofs, walls, etc? Noel

The 0.5mm will do for everything once you get the hang of it. There's a regulating screw at the rear of the airbrush to prevent the trigger and needle fully retracting, so you can throttle the amount of opening to suit the amount paint you want to spray.

 

Other airbrushes also have valve underneath the nozzle which when tightened, will also regulate the amount of air entering the nozzle. I rarely use a 0.2mm or 0.3mm brush for the reasons above.
