Iwata neo spares

No matter what the needle and nozzle size you should be able to introduce from zero to one hundred per cent of the maximum flow by controlling the amount with the trigger. I don't see what is confusing about this

Of course a larger diameter will pass more paint at maximum flow, with the needle fully retracted, but that's not the point.

I just can't wait to try the brush out I just looks cool.

Completely agree Steve.

But ! The amount of paint being released for the full range of a trigger releases with a .35 needle near 3 times that of a .2 needle. This is true for half the trigger range or what ever amount the trigger is pulled back.

My point was that a .2 needle releases two thirds less paint than a .35 what ever the trigger position. Therefore you must have far better control over the amount of paint released one to the other over the trigger range..

Actually in reality this is probably closer than those amounts quoted. But with an Iwata HPBS (.35) compared with an Iwata HPBH (.22) it takes 16 secs to clear a cup of airbrush cleaner compared to 28 secs full flow.

Also think that with a very much less release of paint from a .2 that this will enable much less PSI to be achieved. With my relatively short experience with the .2 I have been down to 8PSI. I could not achieve that with a .35. But then that may be my inexperience. As mentioned earlier I was not getting by a long way the control on the .35 to the .2 with close up detail work.

Be pleased and interested to get others experience here.

Well for what it is worth I use a Tamiya basic airbrush with a 0.3mm nozzle airbrush and it can do lines as thin as Steve mentions as well as broad passes with the trigger limit set full back (Tamiya have a slide which limits the needle movement on top of the airbrush). Have not had any issues with spraying thin lines, unless I get the paint consistency wrong (Humbrol, White Ensign and Xtracolour enamels), but that is a user issue and not the fault of the airbrush. I can't adjust the air pressure on the compressor, just the needle aperture.
