Iwata Micron 0.23 vs 0.18? -.-

No difference at all Husky, in fact some say that you can get a finer line with the .23 I don't know since I don't have one. but if someone has then please join in the conversation.

There is a difference, for sure - just may not be what you think it is. It is quite possible that most, and I do mean most, may never develop the technical skill(s) to take advantage of one over the other.

Aside from the advertised numbers - .18 vs. .23 (if you physically measure you will find something quite different in nozzle size) - what you will find is that the relationship between needle and nozzle vary between the two. Even though they both use the same needle contour, they relate to the nozzle completely different from one another.
 
is there a difference how much reducer you need?
That depends on the paint but CI will flow through either nozzle without reduction @30psi.
But as far as seeing a huge difference in how they spray not really , The .18 seems to allow paint to start flowing out faster then the .23 But line for line pretty much the same.
Are you thinking of buying one?

yep, it's slowly time to up my game. I am thinking about buying micron and hp for some time now. I kinda feel it's time to get something, cause I see I am here to stay - in airbrushing I mean. I find my self keep going to sites to check prices and I am doing this for quite some time now. I was checking side feed versions of both series.

edit:Maybe it would be more logical to go hp first, dunno still thinking about it...

I am also wondering if this goes on sbs and what benefits would user got with conversion

1 94 i 535 2 Fluid Head System 0.23 mm - C2
https://www.dixieart.com/MicronParts.html

there is also on the same link

1 94 i 535 1 Fluid Head System 0.18 mm - C1
I wonder if this can go on micron cs and what would user gain with this conversion

But if I understood DaveG correctly, you should be quite an expert to notice the difference.

Mine is the CM-C+ while the gain isn't much I can go to a super low pressure 1psi with the .18 set up .
 
If I wanted a Micron, and a "C cup was on the table, virtually 10 or 10 times I would choose the Creos GSI PS770/771. If a "B" or "SB" was my goal, I would go with the Iwata .18 Micron, and eventually change out the nozzle for the 770/771...

By measurement, the 770/771 nozzle is physically the largest among the .18/.23 bunch, and allows for a level of forgiveness while in action. You give up nothing in terms of fine detail potential either.
 
Not sure what import taxes and shipping
22% is taxes i think so it would be cheaper at aircraft.net for me.Mr hobby PS 770 is 300 Euros, Micron sbs is 410 Euros. But I am looking mostly for side feed. For the amount of money mr.hobby cost, it is very tempting, but I would love to see them make side feed option as well.

I guess it's time to send 2 mails. :rolleyes:

One to Mr.Hobby and tell them to start making side feed airbrushes.
The second one to Iwata and tell them if they already bought H&S, they need to buy Rotring patents and make those pencil like airbrushes so I can order one :laugh:

what will the reduction be on that low pressure @Mr.Micron ?


I'll post soon about the cost of taxes and shipping...Ordered the 770 from spraygunner he had on sale (210$ / 195 E)... Although it's mention at the invoice a free shiping cost, but I doubt that stands for overseas shipping...
the price for 770 in Europe is about 300 Euro
 
I only have the one set (.18) on my Micron, but I have multiple size sets for both my Eclipse and VL.

My experience with those is that the size doesn't pertain to any relative "ceiling" in terms of line width or quality. You can ultimately pull the same thinness and quality lines with the larger size as with the smaller.

The difference is a trade off between trigger handling and paint reduction/pigment size. A smaller nozzle/needle gives you a broader response curve in terms of paint volume-to-trigger travel, making it much easier to find and hold the "sweet spot" for fine lines, as well as giving you better general control over line width at the "fine" end. It's easier to do a tiny dagger stroke with a smaller nozzle/needle, as trigger travel between the beginning and ending widths of the stroke will be larger.

I can do Micron-thin lines using my Eclipse with the .5 nozzle/needle installed, BUT the trigger sweet spot is so tiny it's basically an on/off switch that takes very careful finger control to hit. I can do the micro lines, but forget micro dagger strokes, and a needle stop would become desirable for repeating lines, whereas I never really use the stop at all on either my Micron or the .3 set on my Eclipse.

The cost of that is the brush will have less tolerance for paint viscosity or larger/irregular pigment sizes as you go down in needle/nozzle size, as the passage the paint has to flow through at the tip becomes both narrower in an absolute sense, and narrower relative to its length. The venturi effect has to work harder to pull more viscous paint through a narrower passage, and large or irregular pigment particles have more opportunity to bind and clog in a narrow passage.

This means you can sort of get the benefits of a smaller nozzle/needle without the viscosity/particle size drawbacks by switching to a taller trigger. Though that of course has it's own ergonomic tradeoffs.

If you were to ask me what the difference is between a stock Micron and an Eclipse with an extra tall trigger pad mod, I'd say better atomization and ergonomics on the Micron, more forgiving paint tolerance on the Eclipse, but not line width or control.

Very nicely put Nessus. That’s a great way to explain things.
